技术领域technical field

本发明涉及一种车辆。The invention relates to a vehicle.

背景技术Background technique

在电动车辆中,通过使冷却水循环过作为其动力源的电机来冷却电机。因此,在电动车辆搭载有用于冷却电机的冷却水的散热器。另一方面,将电动车辆与发动机车辆进行比较,作为电动车辆的动力源的电机的发热量少于作为发动机车辆的动力源的发动机的发热量。因此,需要向用于冷却电机的冷却水的散热器供给的空气量少于需要向用于冷却发动机的冷却水的散热器供给的空气量。因此,在以往的电动车辆中,如例如下述的专利文献1所记载的那样,用于将车辆前方的空气导入散热器的格栅开口部的开度被设定为小于发动机车辆的格栅开口部的开度。具体而言,在专利文献1所记载的车辆中,以仅与散热器的下半部分相对的方式形成格栅开口部。在该车辆形成有将从格栅开口部导入的空气导向散热器的管道。管道形成为其流路截面积从格栅开口部朝向散热器逐渐扩大。像专利文献1所记载的车辆那样通过缩小格栅开口部能够提高车辆的空气动力性能,使延长车辆的续航距离等成为可能。In electric vehicles, the motor is cooled by circulating cooling water through the motor as its power source. Therefore, electric vehicles are equipped with a radiator for cooling water for cooling the motor. On the other hand, comparing an electric vehicle with an engine vehicle, a motor that is a power source of the electric vehicle generates less heat than an engine that is a power source for the engine vehicle. Therefore, the amount of air that needs to be supplied to the radiator for cooling the cooling water of the motor is smaller than the amount of air that needs to be supplied to the radiator for cooling the cooling water of the engine. Therefore, in a conventional electric vehicle, as described in, for example, Patent Document 1 below, the opening degree of the grille opening for introducing the air in front of the vehicle into the radiator is set to be smaller than that of the grille of the engine vehicle. The opening degree of the opening. Specifically, in the vehicle described in Patent Document 1, the grille opening is formed so as to face only the lower half of the radiator. In this vehicle, a duct is formed to guide the air introduced from the grill opening to the radiator. The duct is formed such that its flow path cross-sectional area gradually expands from the grill opening toward the radiator. By reducing the grille opening as in the vehicle described in Patent Document 1, the aerodynamic performance of the vehicle can be improved, and the cruising distance of the vehicle can be extended.

在专利文献1所记载的管道中,与在上下方向上靠近格栅开口部的部分的压力相比,在上下方向上远离格栅开口部的部分的压力容易变高。其结果是,在散热器中,与流过靠近格栅开口部的部分的空气的风量相比,流过远离格栅开口部的部分的空气的风量变少。这样的空气的风量分布的偏差成为使散热器的热交换效率降低的要因,并不优选。In the duct described in Patent Document 1, the pressure of the portion farther from the grill opening in the vertical direction tends to be higher than the pressure of the portion close to the grill opening in the vertical direction. As a result, in the radiator, the air volume of the air flowing through the portion away from the grill opening becomes smaller than the air volume of the air flowing through the portion close to the grill opening. Such variation in the air volume distribution of the air is not preferable because it causes a decrease in the heat exchange efficiency of the radiator.

发明内容Contents of the invention

本发明的目的在于,提供一种能够提高热交换器的热交换效率的车辆。An object of the present invention is to provide a vehicle capable of improving the heat exchange efficiency of a heat exchanger.

本发明的一方式的车辆具备:热交换器,该热交换器与从格栅开口部导入的空气进行热交换;开闭装置,该开闭装置能够通过开闭部的开闭动作改变向热交换器供给的空气的风量;以及控制部,该控制部控制开闭装置。格栅开口部的开口面积小于热交换器的前表面投影面积。开闭装置具有第一开闭部和第二开闭部作为开闭部,该第一开闭部对该开闭装置的第一部位进行开闭,该第二开闭部对在该开闭装置中与第一部位相比远离格栅开口部的第二部位进行开闭。控制部以使第一部位的开度小于第二部位的开度的方式使第一开闭部和第二开闭部动作。A vehicle according to an aspect of the present invention includes: a heat exchanger for exchanging heat with air introduced from the grill opening; an air volume of air supplied by the exchanger; and a control unit that controls the opening and closing device. The opening area of the grill opening is smaller than the projected area of the front surface of the heat exchanger. The opening and closing device has a first opening and closing part and a second opening and closing part as the opening and closing part. The first opening and closing part opens and closes the first part of the opening and closing device. A second portion of the device that is farther from the grill opening than the first portion is opened and closed. The control unit operates the first opening and closing unit and the second opening and closing unit so that the opening degree of the first portion is smaller than the opening degree of the second portion.

通过像该结构这样,使开闭装置的第一部位的开度小于开闭装置的第二部位的开度,与开闭装置的第一部位相比,空气变得容易向第二部位流动。由此,能够使在热交换器中配置于格栅开口部的附近的部分处的空气的压力向变高的方向变化,并且能够使配置于远离格栅开口部的部分处的空气的压力向变低的方向变化。通过像这样通过开闭装置的开度的偏差来使空气的压力局部地变化,能够减轻因格栅开口部的位置导致的空气的压力的偏差。其结果是,能够减轻向热交换器供给的空气的风量的偏差,因此能够提高热交换器的热交换效率。By making the opening degree of the first part of the switch device smaller than the opening degree of the second part of the switch device in this configuration, air flows more easily to the second part than to the first part of the switch device. Thereby, in the heat exchanger, the pressure of the air arranged in the vicinity of the grill opening can be changed to increase the pressure, and the pressure of the air arranged in the part far from the grill opening can be increased. Going low for directional changes. By locally changing the pressure of the air due to the variation in the opening degree of the opening and closing device in this way, it is possible to reduce the variation in the air pressure due to the position of the grill opening. As a result, variation in the air volume of the air supplied to the heat exchanger can be reduced, and thus the heat exchange efficiency of the heat exchanger can be improved.

接着,对使用了散热器5的冷却回路和使用了室外热交换器6的热泵装置各自的概略结构进行说明。Next, the respective schematic configurations of the cooling circuit using the radiator 5 and the heat pump device using the outdoor heat exchanger 6 will be described.

如图2所示,在冷却回路20设置有散热器5、泵21以及发热体22。在冷却回路20中,冷却水在这些要素循环。散热器5通过使在其内部流动的冷却水与在其外部流动的空气进行热交换来对冷却水进行冷却。泵21吸入被散热器5冷却后的冷却水,并向发热体22排出。冷却水通过该泵21的驱动而在冷却回路20循环。泵21是基于电力的供给而驱动的电动式的泵。发热体22包含构成车辆C的动力单元的电机220、逆变器装置221、电池222等。逆变器装置221将向电池222充电的直流电力转换为交流电力而向电机220供给,并且将由电机220的再生动作而产生的交流电力转换为直流电力而向电池222充电。从泵21排出的冷却水流过电机220、逆变器装置221以及电池222。该冷却水通过吸收电机220等的热而将它们冷却。因吸收电机220等的热而温度上升后的冷却水通过被向散热器5供给而再次被冷却。As shown in FIG. 2 , the cooling circuit 20 is provided with a radiator 5 , a pump 21 , and a heating element 22 . In the cooling circuit 20, cooling water circulates through these elements. The radiator 5 cools the cooling water by exchanging heat between the cooling water flowing inside and the air flowing outside the radiator 5 . The pump 21 sucks in the cooling water cooled by the radiator 5 and discharges it to the heating element 22 . Cooling water circulates through the cooling circuit 20 by driving the pump 21 .

The cooling water whose temperature has risen by absorbing heat from the motor 220 and the like is supplied to the radiator 5 to be cooled again.

热泵装置30是车辆C的空调装置40的构成要素。在热泵装置30设有室外热交换器6、水冷冷凝器31以及蒸发器32。在热泵装置30中,制冷剂在这些要素循环。热泵装置30通过使制冷剂的流动状态在空调装置40以制冷模式动作的情况和空调装置40以制热模式动作的情况下变化,而实现车室内的制冷和制热。The heat pump device 30 is a component of the air conditioner 40 of the vehicle C. As shown in FIG. The heat pump device 30 is provided with an outdoor heat exchanger 6 , a water-cooled condenser 31 , and an evaporator 32 . In the heat pump device 30, the refrigerant circulates through these elements. The heat pump device 30 realizes cooling and heating of the vehicle interior by changing the flow state of the refrigerant between when the air conditioner 40 operates in the cooling mode and when the air conditioner 40 operates in the heating mode.

具体而言,在空调装置40以制冷模式动作的情况下,热泵装置30使制冷剂在室外热交换器6和蒸发器32循环。此时,室外热交换器6作为冷凝器动作。即,室外热交换器6通过使在其内部流动的制冷剂与在其外部流动的空气进行热交换来冷却制冷剂。通过被室外热交换器6冷却而生成的高压的液相制冷剂在因通过设置于热泵装置30的减压阀而被减压转移为低压的液相制冷剂之后,被向蒸发器32供给。蒸发器32通过使在其内部流动的制冷剂与流过空调装置40的空调管道41的空气进行热交换来冷却空调管道41内的空气。该空气通过空调管道41而向车室内吹送,由此进行车室内的制冷。在蒸发器32中,低压的液相制冷剂通过与空气的热交换而转移为低压的气相制冷剂。该低压的气相制冷剂在因被设置于热泵装置30的泵压缩而转移为高温和高压的气相制冷剂之后,通过向被室外热交换器6供给而再次被冷却。Specifically, when the air conditioner 40 operates in the cooling mode, the heat pump device 30 circulates the refrigerant between the outdoor heat exchanger 6 and the evaporator 32 . At this time, the outdoor heat exchanger 6 operates as a condenser. That is, the outdoor heat exchanger 6 cools the refrigerant by exchanging heat between the refrigerant flowing inside and the air flowing outside. The high-pressure liquid-phase refrigerant generated by being cooled by the outdoor heat exchanger 6 is decompressed and transferred to a low-pressure liquid-phase refrigerant by passing through a pressure reducing valve provided in the heat pump device 30 , and then supplied to the evaporator 32 . The evaporator 32 cools the air in the air conditioning duct 41 by exchanging heat between the refrigerant flowing therein and the air flowing through the air conditioning duct 41 of the air conditioning device 40 . This air is blown into the vehicle interior through the air-conditioning duct 41, thereby cooling the vehicle interior. In the evaporator 32, the low-pressure liquid-phase refrigerant is transferred to a low-pressure gas-phase refrigerant by heat exchange with air. After the low-pressure gas-phase refrigerant is compressed by the pump provided in the heat pump device 30 and transferred to a high-temperature and high-pressure gas-phase refrigerant, it is supplied to the outdoor heat exchanger 6 and cooled again.

另一方面,在空调装置40以制热模式动作的情况下,热泵装置30使制冷剂在室外热交换器6和水冷冷凝器31循环。此时,室外热交换器6作为吸热器动作。即,室外热交换器6通过使在其内部流动的制冷剂与在其外部流动的空气进行热交换来加热制冷剂。因被室外热交换器6加热而生成的低压的气相制冷剂在通过设置于热泵装置30的泵而转移为高温和高压的气相制冷剂之后,被向水冷冷凝器31供给。在水冷冷凝器31中,通过使从热泵装置30供给的高温和高压的气相制冷剂与在空调装置40的冷却水回路42流动的冷却水进行热交换来加热冷却水。在冷却水回路42中,除了水冷冷凝器31之外,还设置有空调装置40的加热器芯43和泵44。泵44使冷却水在冷却水回路42中循环。加热器芯43通过使在其内部流动的冷却水与在空调管道41流动的空气进行热交换来加热在空调管道41内流动的空气。该空气通过空调管道41向车室内吹送,由此进行车室内的制热。在水冷冷凝器31中,高温和高压的气相制冷剂通过与冷却水的热交换而转移为高压的液相制冷剂。该高压的液相制冷剂在通过设置于热泵装置30的减压阀而被减压转移为低压的液相制冷剂之后,通过被向室外热交换器6供给而再次被加热。On the other hand, when the air conditioner 40 operates in the heating mode, the heat pump device 30 circulates the refrigerant through the outdoor heat exchanger 6 and the water-cooled condenser 31 . At this time, the outdoor heat exchanger 6 operates as a heat sink. That is, the outdoor heat exchanger 6 heats the refrigerant by exchanging heat between the refrigerant flowing inside and the air flowing outside. The low-pressure gas-phase refrigerant generated by being heated by the outdoor heat exchanger 6 is transferred to a high-temperature and high-pressure gas-phase refrigerant by the pump provided in the heat pump device 30 , and then supplied to the water-cooled condenser 31 . In the water-cooled condenser 31 , the cooling water is heated by exchanging heat between the high-temperature and high-pressure gas-phase refrigerant supplied from the heat pump device 30 and the cooling water flowing in the cooling water circuit 42 of the air conditioner 40 . In the cooling water circuit 42 , in addition to the water-cooled condenser 31 , a heater core 43 and a pump 44 of the air conditioner 40 are provided. The pump 44 circulates cooling water in the cooling water circuit 42 . The heater core 43 heats the air flowing in the air-conditioning duct 41 by exchanging heat between the cooling water flowing therein and the air flowing in the air-conditioning duct 41 . The air is blown into the vehicle interior through the air-conditioning duct 41 to heat the vehicle interior. In the water-cooled condenser 31, high-temperature and high-pressure gas-phase refrigerant is transferred into high-pressure liquid-phase refrigerant through heat exchange with cooling water. The high-pressure liquid-phase refrigerant is decompressed and transferred to a low-pressure liquid-phase refrigerant by a pressure reducing valve provided in the heat pump device 30 , and then is supplied to the outdoor heat exchanger 6 to be heated again.

接着,对风门装置8的概略结构进行说明。Next, a schematic configuration of the damper device 8 will be described.

以下,也将框架主体部500的长边方向X称作左右方向,并将框架主体部500的短边方向Z称作上下方向。另外,也将与左右方向X和上下方向Z这双方正交的由箭头Y表示的方向称作“空气流动方向Y”。Hereinafter, the longitudinal direction X of the frame main body 500 is also referred to as a left-right direction, and the short-side direction Z of the frame main body 500 is also referred to as an up-down direction. In addition, the direction shown by the arrow Y perpendicular to both the left-right direction X and the up-down direction Z is also referred to as "air flow direction Y".

纵框架加强部501设置为用于加强框架主体部500。横框架加强部502设置为用于加强框架主体部500且保持叶片51。通过纵框架加强部501和横框架加强部502将框架主体部500的内侧的空间划分为四个开口区域A11~A14。The vertical frame reinforcement part 501 is provided to reinforce the frame main body part 500 . The transverse frame reinforcement part 502 is provided for reinforcing the frame main body part 500 and holding the blade 51 . The space inside the frame main body 500 is divided into four opening areas A11 to A14 by the vertical frame reinforcement 501 and the lateral frame reinforcement 502 .

此外,以下,将四个开口区域A11~A14中的与横框架加强部502相比配置于上方的两个开口区域A11、A12称作“上侧开口区域A11、A12”,并将与横框架加强部502相比配置于下方的两个开口区域A13、A14称作“下侧开口区域A13、A14”。In addition, hereinafter, among the four opening areas A11 to A14, the two opening areas A11 and A12 arranged above the horizontal frame reinforcement part 502 are referred to as "upper side opening areas A11 and A12", and will be compared with the horizontal frame reinforcement part 502. The two opening areas A13 and A14 disposed below the reinforcing portion 502 are referred to as "lower opening areas A13 and A14".

如图1所示,下侧开口区域A13、A14的大致下半部分位于与格栅开口部2相对的位置。格栅开口部2的开口面积小于散热器5和室外热交换器6各自的前表面投影面积。在本实施方式中,下侧开口区域A13、A14相当于第一部位。另外,上侧开口区域A11、A12相当于与第一部位相比远离格栅开口部2的第二部位。As shown in FIG. 1 , substantially lower half portions of the lower opening areas A13 and A14 are positioned to face the grille opening 2 . The opening area of the grill opening 2 is smaller than the respective front surface projected areas of the radiator 5 and the outdoor heat exchanger 6 . In the present embodiment, the lower opening areas A13 and A14 correspond to the first portion. In addition, the upper opening areas A11 and A12 correspond to a second site that is farther from the grill opening 2 than the first site.

The lower part 5b of the radiator 5 other than the upper part 5a and the lower part 6b of the outdoor heat exchanger 6 other than the upper part 6a are arranged so as to face the lower opening areas A13 and A14 of the damper device 8 . . In addition, the two-dot chain line described in the heat sink 5 of FIG. 1 shows the boundary part of the upper part 5a of the heat sink 5, and the lower part 5b. Similarly, the two-dot chain line described in the outdoor heat exchanger 6 indicates the boundary portion between the upper part 6 a and the lower part 6 b of the outdoor heat exchanger 6 .

如图3所示,多个叶片51分别配置在框架50的四个开口区域A11~A14。在四个开口区域A11~A14中,多个叶片51以在上下方向Z上具有长边方向的方式配置,并且在左右方向X上排列地配置。以下,为了方便,将多个叶片51中的配置于框架主体部500的上侧开口区域A11、A12的叶片51称作“上侧叶片511”,并将配置于下侧开口区域A13、A14的叶片51称作“下侧叶片512”。在本实施方式中,叶片51相当于开闭部,下侧叶片512相当于第一开闭部,上侧叶片511相当于第二开闭部。As shown in FIG. 3 , the plurality of vanes 51 are respectively arranged in the four opening areas A11 to A14 of the frame 50 . In the four opening areas A11 to A14, the plurality of blades 51 are arranged so as to have a longitudinal direction in the up-down direction Z, and are arranged side by side in the left-right direction X. As shown in FIG. Hereinafter, for convenience, among the plurality of blades 51, the blades 51 disposed in the upper opening areas A11 and A12 of the frame main body 500 are referred to as "upper blades 511", and the blades 51 disposed in the lower opening areas A13 and A14 are referred to as "upper blades 511". The blade 51 is referred to as a "lower blade 512". In this embodiment, the vane 51 corresponds to the opening and closing unit, the lower vane 512 corresponds to the first opening and closing unit, and the upper vane 511 corresponds to the second opening and closing unit.

电机52通过螺钉等固定于框架主体部500的上表面的一端部。电机52通过经由未图示的连杆机构向上侧叶片511和下侧叶片512施加旋转力来使各叶片511、512旋转。此外,本实施方式的风门装置8能够独立地控制上侧叶片511和下侧叶片512各自的开度。The motor 52 is fixed to one end of the upper surface of the frame main body 500 with screws or the like. The motor 52 rotates the blades 511 , 512 by applying rotational force to the upper blade 511 and the lower blade 512 via a link mechanism not shown. In addition, the damper device 8 of the present embodiment can independently control the respective opening degrees of the upper blade 511 and the lower blade 512 .

在该风门装置8中,在上侧叶片511和下侧叶片512处于开状态的情况下,在各上侧叶片511之间形成间隙,并且在各下侧叶片512之间形成间隙,因此,通过这些间隙,从格栅开口部2导入的空气被向散热器5和室外热交换器6供给。另一方面,在上侧叶片511和下侧叶片512处于闭状态时,各叶片511、512之间的间隙被封闭,因此,向散热器5和室外热交换器6的空气的供给被切断。另外,通过独立地控制上侧叶片511和下侧叶片512各自的开度,能够单独地调整分别向图1所示的散热器5的上部5a和下部5b供给的空气量以及分别向室外热交换器6的上部6a和下部6b供给的空气量。In this damper device 8, when the upper blades 511 and the lower blades 512 are opened, a gap is formed between the upper blades 511 and a gap is formed between the lower blades 512. In these gaps, the air introduced from the grill opening 2 is supplied to the radiator 5 and the outdoor heat exchanger 6 . On the other hand, when the upper vane 511 and the lower vane 512 are in the closed state, the gap between the vanes 511, 512 is closed, so that the supply of air to the radiator 5 and the outdoor heat exchanger 6 is cut off. In addition, by independently controlling the openings of the upper blades 511 and the lower blades 512, it is possible to individually adjust the amount of air supplied to the upper part 5a and the lower part 5b of the radiator 5 shown in FIG. The amount of air supplied by the upper part 6a and the lower part 6b of the device 6.

接着,对车辆C的电结构进行说明。Next, the electrical configuration of the vehicle C will be described.

如图4所示,在车辆C设置有用于检测其行驶状态、冷却回路20的状态、热泵装置30的状态、车辆C的内外的环境状态等的各种传感器60。传感器60包含外气温度传感器61、车速传感器62、制冷剂压力传感器63、水温传感器64、内气温度传感器65、外气温度传感器66等。外气温度传感器61检测作为车辆C的外部的空气的外气的温度。车速传感器62检测作为车辆C的行驶速度的车速。制冷剂压力传感器63检测在热泵装置30中从室外热交换器6流出的制冷剂的压力。水温传感器64检测在冷却回路20中从发热体22流出的冷却水的温度。内气温度传感器65检测作为车辆C的室内的温度的内气温度。各传感器61~65输出与检测到的物理量对应的信号。As shown in FIG. 4 , the vehicle C is provided with various sensors 60 for detecting its driving state, the state of the cooling circuit 20 , the state of the heat pump device 30 , the environmental state inside and outside the vehicle C, and the like. The sensors 60 include an outside air temperature sensor 61 , a vehicle speed sensor 62 , a refrigerant pressure sensor 63 , a water temperature sensor 64 , an inside air temperature sensor 65 , an outside air temperature sensor 66 , and the like. The outside air temperature sensor 61 detects the temperature of outside air which is air outside the vehicle C. As shown in FIG. The vehicle speed sensor 62 detects the vehicle speed as the running speed of the vehicle C. As shown in FIG. The refrigerant pressure sensor 63 detects the pressure of the refrigerant flowing out of the outdoor heat exchanger 6 in the heat pump device 30 . The water temperature sensor 64 detects the temperature of the cooling water flowing out of the heating element 22 in the cooling circuit 20 . The interior air temperature sensor 65 detects the interior air temperature which is the temperature of the interior of the vehicle C. As shown in FIG. Each of the sensors 61 to 65 outputs a signal corresponding to the detected physical quantity.

在车辆C设置有在使车辆C起动时被操作的起动开关70、用于操作空调装置40的操作部71。操作部71包含在进行车室内的制冷或除湿时被操作的A/C开关710。The vehicle C is provided with a start switch 70 that is operated when the vehicle C is started, and an operation unit 71 for operating the air conditioner 40 . Operation unit 71 includes an A/C switch 710 that is operated when cooling or dehumidifying the vehicle interior.

而且,在车辆C还设置有动力总成ECU(Electronic Control Unit,电子控制单元)80、空调ECU81以及热系统ECU82。ECU80~82构成为以具有CPU、ROM、RAM等的微型计算机为中心。ECU80~82通过执行预先存储于ROM的程序来执行各种控制。各ECU80~82能够利用设置于车辆C的CAN等网络通信Nc来彼此接收各种信息。Further, the vehicle C is also provided with a powertrain ECU (Electronic Control Unit) 80 , an air conditioner ECU 81 , and a thermal system ECU 82 . ECU80-82 is comprised centering on the microcomputer which has CPU, ROM, RAM, etc. ECU80-82 executes various controls by executing the program prestored in ROM. Each of the ECUs 80 to 82 can receive various information from each other by using network communication Nc such as CAN provided in the vehicle C.

动力总成ECU80是统筹控制车辆C的行驶状态的部分。例如,在检测到起动开关70被进行了接通操作时,在此之后直到起动开关70被进行切断操作为止的期间,动力总成ECU80基于由油门位置传感器检测到的油门位置来设定电机220的目标输出转矩。并且,动力总成ECU80基于目标输出转矩来设定电机220的目标通电量,并且以使电机220的实际的通电量追随目标通电量的方式驱动逆变器装置221。动力总成ECU80通过这样的电机220的通电控制来控制车辆C的行驶状态。The powertrain ECU 80 is a part that overall controls the running state of the vehicle C. For example, when it is detected that the starter switch 70 is turned on, and thereafter until the starter switch 70 is turned off, the powertrain ECU 80 sets the position of the motor 220 based on the accelerator position detected by the accelerator position sensor. target output torque. Then, powertrain ECU 80 sets the target energization amount of motor 220 based on the target output torque, and drives inverter device 221 so that the actual energization amount of motor 220 follows the target energization amount. The powertrain ECU 80 controls the running state of the vehicle C through such energization control of the motor 220 .

空调ECU81是统筹控制空调装置40的部分。例如,内气温度传感器65和操作部71各自的输出信号输入到空调ECU81。在A/C开关710被进行了接通操作的情况下,空调ECU81通过使图2所示的热泵装置30以制冷模式动作来进行车室内的制冷或除湿。另一方面,在由内气温度传感器65检测的内气温为规定的制热温度判定值以下的情况下,空调ECU81通过使图2所示的热泵装置30以制热模式动作来进行车室内的制热。制热温度判定值是预先设定的温度,例如被设定为“15℃”。The air conditioner ECU 81 is a part that overall controls the air conditioner 40 . For example, the output signals of the inside air temperature sensor 65 and the operation unit 71 are input to the air conditioner ECU 81 . When the A/C switch 710 is turned on, the air conditioner ECU 81 operates the heat pump device 30 shown in FIG. 2 in the cooling mode to cool or dehumidify the vehicle interior. On the other hand, when the internal air temperature detected by the internal air temperature sensor 65 is equal to or lower than a predetermined heating temperature judgment value, the air conditioner ECU 81 operates the heat pump device 30 shown in FIG. Heating. The heating temperature judgment value is a preset temperature, for example, set to "15°C".

热系统ECU82是通过主要驱动风门装置8进行开闭来控制向散热器5和室外热交换器6供给的空气的风量的部分。具体而言,各种传感器60、起动开关70及操作部71各自的输出信号输入到热系统ECU82。热系统ECU82基于传感器60的输出信号来检测各种状态量,并且基于起动开关70和操作部71各自的输出信号来检测它们的操作状态。热系统ECU82基于由传感器60检测的各种状态量以及起动开关70和操作部71各自的操作状态等单独地设定风门装置8的上侧叶片511和下侧叶片512各自的目标开度,在此基础上,驱动风门装置8的电机52以使这些叶片511、512各自的开度成为目标开度。这样,在本实施方式中,热系统ECU82相当于控制风门装置8的控制部。The heat system ECU 82 is a part that controls the volume of air supplied to the radiator 5 and the outdoor heat exchanger 6 by mainly driving the damper device 8 to open and close. Specifically, output signals of various sensors 60 , starter switch 70 , and operation unit 71 are input to thermal system ECU 82 . The thermal system ECU 82 detects various state quantities based on the output signal of the sensor 60 , and detects the operating states of the starter switch 70 and the operating portion 71 based on their respective output signals. The thermal system ECU 82 individually sets the respective target opening degrees of the upper vane 511 and the lower vane 512 of the damper device 8 based on various state quantities detected by the sensor 60 and the respective operating states of the starter switch 70 and the operating portion 71 , and then On top of this, the motor 52 of the damper device 8 is driven so that the respective opening degrees of the vanes 511 and 512 become the target opening degrees. Thus, in the present embodiment, the thermal system ECU 82 corresponds to a control unit that controls the damper device 8 .

接着,对由热系统ECU82执行的风门装置8的驱动控制进行具体说明。Next, the drive control of the damper device 8 executed by the thermal system ECU 82 will be specifically described.

热系统ECU82以规定的周期重复执行图5所示的处理。此外,热系统ECU82在开始图5所示的处理时,将风门装置8的上侧叶片511和下侧叶片512各自的位置设定为初始位置。初始位置例如是与全闭状态对应的位置。The thermal system ECU 82 repeatedly executes the processing shown in FIG. 5 at a predetermined cycle. Further, when the thermal system ECU 82 starts the process shown in FIG. 5 , it sets the respective positions of the upper blade 511 and the lower blade 512 of the damper device 8 as initial positions. The initial position is, for example, a position corresponding to the fully closed state.

如图5所示,首先,作为步骤S10的处理,热系统ECU82判断起动开关70是否被进行了接通操作。在起动开关70没有被进行接通操作的情况下,热系统ECU82在步骤S10的处理中进行否定的判断,并暂时结束图5所示的处理。As shown in FIG. 5 , first, as the process of step S10 , the thermal system ECU 82 determines whether or not the start switch 70 has been turned on. When the start switch 70 is not turned on, the thermal system ECU 82 makes a negative judgment in the processing of step S10 and temporarily ends the processing shown in FIG. 5 .

在起动开关70被进行了接通操作的情况下,热系统ECU82在步骤S10的处理中进行肯定的判断,作为接下来的步骤S11的处理,判断是否需要向散热器5和室外热交换器6供给空气。例如,热系统ECU82基于同时满足了以下的(a1)和(a2)所示的条件,而判断为不需要向散热器5和室外热交换器6供给空气。When the starter switch 70 is turned on, the thermal system ECU 82 makes an affirmative judgment in the processing of step S10, and judges whether or not it is necessary to heat the radiator 5 and the outdoor heat exchanger 6 as the processing of the next step S11. supply air. For example, the thermal system ECU 82 determines that it is not necessary to supply air to the radiator 5 and the outdoor heat exchanger 6 based on the simultaneous satisfaction of the conditions shown in (a1) and (a2) below.

(a1)A/C开关710没有被进行接通操作,且由内气温度传感器65检测到的内气温高于制热温度判定值的情况。即,不需要使热泵装置30以制冷模式和制热模式中的任一个进行动作的情况。(a1) A case where the A/C switch 710 is not turned on and the internal air temperature detected by the internal air temperature sensor 65 is higher than the heating temperature determination value. That is, it is not necessary to operate the heat pump device 30 in either the cooling mode or the heating mode.

(a2)由水温传感器64检测到的冷却水的温度在规定的温度判定值以下的情况。即,不需要冷却发热体22的情况。温度判定值被预先设定为能够判断是否需要冷却发热体22的值。(a2) When the temperature of the cooling water detected by the water temperature sensor 64 is equal to or less than a predetermined temperature judgment value. That is, it is not necessary to cool the heating element 22 . The temperature determination value is set in advance as a value capable of determining whether or not cooling of the heating element 22 is necessary.

此外,关于(a2),例如在发热体22所包含的电机220、逆变器装置221及电池222分别设有水温传感器64的情况下,可以对各自的冷却水温单独设定温度判定值。在该情况下,对于电机220的冷却水温的温度判定值被设定为例如“65℃”,对于电池222的冷却水温的温度判定值被设定为例如“40℃”。Also, regarding (a2), for example, when the motor 220, the inverter device 221, and the battery 222 included in the heating element 22 are provided with water temperature sensors 64, the temperature judgment values can be set individually for the respective cooling water temperatures. In this case, the temperature judgment value for the cooling water temperature of the motor 220 is set to, for example, "65°C", and the temperature judgment value for the cooling water temperature of the battery 222 is set to, for example, "40°C".

在同时满足上述的(a1)和(a2)的条件的情况下,热系统ECU82判断为不需要向散热器5和室外热交换器6供给空气,在步骤S11的处理中进行否定的判断。在该情况下,作为步骤S12的处理,热系统ECU82执行将风门装置8的上侧开口区域A11、A12和下侧开口区域A13、A14设为全闭状态的全闭控制。具体而言,热系统ECU82驱动电机52,以将上侧叶片511和下侧叶片512都设为全闭状态。由此,通过格栅开口部2后的空气的导入被切断,能够提高车辆C的空气动力性能。因此,能够提高车辆C的电力经济性。When the above-mentioned conditions (a1) and (a2) are satisfied, thermal system ECU 82 determines that air supply to radiator 5 and outdoor heat exchanger 6 is unnecessary, and makes a negative determination in the process of step S11. In this case, thermal system ECU 82 executes full closing control to bring upper opening areas A11 , A12 and lower opening areas A13 , A14 of damper device 8 into a fully closed state as processing in step S12 . Specifically, the thermal system ECU 82 drives the motor 52 so that both the upper blade 511 and the lower blade 512 are fully closed. Thereby, the introduction of the air passing through the grille opening 2 is blocked, and the aerodynamic performance of the vehicle C can be improved. Therefore, the power economy of the vehicle C can be improved.

另一方面,在没有满足上述的(a1)和(a2)中的至少一方的条件的情况下,热系统ECU82判断为需要向散热器5和室外热交换器6中的至少一方供给空气。例如没有满足(a1)的条件的情况中存在A/C开关710没有被进行接通操作的情况和由内气温度传感器65检测到的内气温为制热温度判定值以下的情况。在前者的情况下,需要使热泵装置30以制冷模式动作,因此需要向室外热交换器6供给空气。另外,在后者的情况下,需要使热泵装置30以制热模式动作,因此需要向室外热交换器6供给空气。进而,在没有满足(a2)的条件的情况下,即发热体22的冷却水的温度超过了规定的温度判定值的情况下,需要驱动冷却回路20来冷却发热体22,因此需要向散热器5供给空气。On the other hand, when at least one of the conditions (a1) and (a2) above is not satisfied, thermal system ECU 82 determines that air needs to be supplied to at least one of radiator 5 and outdoor heat exchanger 6 . For example, when the condition of (a1) is not satisfied, the A/C switch 710 is not turned on or the internal air temperature detected by the internal air temperature sensor 65 is not higher than the heating temperature judgment value. In the former case, since it is necessary to operate the heat pump device 30 in the cooling mode, it is necessary to supply air to the outdoor heat exchanger 6 . In addition, in the latter case, it is necessary to operate the heat pump device 30 in the heating mode, and thus it is necessary to supply air to the outdoor heat exchanger 6 . Furthermore, when the condition of (a2) is not satisfied, that is, when the temperature of the cooling water of the heat generating body 22 exceeds a predetermined temperature judgment value, it is necessary to drive the cooling circuit 20 to cool the heat generating body 22, so it is necessary to supply heat to the radiator. 5 supply air.

在判定为没有满足上述的(a1)和(a2)中的至少一方的条件,而需要向散热器5和室外热交换器6中的至少一方供给空气的情况下,热系统ECU82在步骤S11的处理中进行肯定的判断,作为接下来的步骤S13的处理,执行调整风门装置8的上侧叶片511和下侧叶片512各自的开度的开度调整控制。具体而言,热系统ECU82将上侧叶片511和下侧叶片512都设为开状态,且驱动电机52,以如图1所示那样使上侧叶片511的开度小于下侧叶片512的开度。通过上侧叶片511和下侧叶片512都成为开状态,能够向散热器5和室外热交换器6供给空气,因此能够驱动冷却回路20和热泵装置30。When it is determined that at least one of the above-mentioned conditions (a1) and (a2) is not satisfied, and it is necessary to supply air to at least one of the radiator 5 and the outdoor heat exchanger 6, the thermal system ECU 82 In the process, affirmative judgment is made, and as the next step S13 process, opening degree adjustment control for adjusting the respective opening degrees of the upper blade 511 and the lower blade 512 of the damper device 8 is executed. Specifically, the thermal system ECU 82 sets both the upper vane 511 and the lower vane 512 to an open state, and drives the motor 52 so that the opening degree of the upper vane 511 is smaller than that of the lower vane 512 as shown in FIG. 1 . Spend. When both the upper vane 511 and the lower vane 512 are opened, air can be supplied to the radiator 5 and the outdoor heat exchanger 6 , so that the cooling circuit 20 and the heat pump device 30 can be driven.

如图5所示,在执行了步骤S12或步骤S13的处理的情况下,作为步骤S14的处理,热系统ECU82判断起动开关70是否被进行了切断操作。在起动开关70没有被进行切断操作的情况下,热系统ECU82在步骤S14的处理中进行否定的判断,并返回步骤S11的处理。另一方面,当热系统ECU82在步骤S14的处理中进行了肯定的判断的情况下,即起动开关70被进行了切断操作的情况下,作为步骤S15的处理,在使上侧叶片511和下侧叶片512位移到初始位置之后,暂时结束图5所示的处理。As shown in FIG. 5 , when the process of step S12 or step S13 is executed, as the process of step S14 , thermal system ECU 82 determines whether or not start switch 70 has been turned off. When the starter switch 70 is not turned off, the thermal system ECU 82 makes a negative judgment in the process of step S14, and returns to the process of step S11. On the other hand, when the thermal system ECU 82 makes an affirmative judgment in the process of step S14, that is, when the start switch 70 is turned off, as the process of step S15, the upper blade 511 and the lower After the side blades 512 are displaced to the initial position, the processing shown in FIG. 5 is temporarily terminated.

根据以上说明的本实施方式的车辆C,能够得到以下的(1)~(5)所示的作用和效果。According to the vehicle C of the present embodiment described above, the operations and effects shown in the following (1) to (5) can be obtained.

(1)通过使下侧叶片512的开度变得小于上侧叶片511的开度,与风门装置8的下侧开口区域A13、A14相比,空气变得更容易向上侧开口区域A11、A12流动。因此,能够使散热器5和室外热交换器6各自的下部5b、6b的空气的压力向变高的方向变化,并且能够使这些上部5a、6a的空气的压力向变低的方向变化。这样,通过风门装置8的开度的偏差使空气的压力局部地变化,由此能够减轻因格栅开口部2的位置导致的空气的压力的偏差。其结果是,能够减轻向散热器5和室外热交换器6供给的空气的风量的偏差,因此能够提高它们的热交换效率。(1) By making the opening of the lower vane 512 smaller than the opening of the upper vane 511, the air becomes easier to open to the upper opening areas A11, A12 than the lower opening areas A13, A14 of the damper device 8. flow. Therefore, the pressure of the air in the lower parts 5b and 6b of the radiator 5 and the outdoor heat exchanger 6 can be changed to be higher, and the pressure of the air in the upper parts 5a and 6a can be changed to be lower. In this way, the variation in the air pressure due to the variation in the opening degree of the damper device 8 can be reduced, thereby reducing the variation in the air pressure due to the position of the grill opening 2 . As a result, variations in the air volumes of the air supplied to the radiator 5 and the outdoor heat exchanger 6 can be reduced, thereby improving their heat exchange efficiency.

(2)风门装置8具备使上侧叶片511和下侧叶片512动作的一个电机52。根据该结构,与分别设置用于使上侧叶片511动作的电机和用于使下侧叶片512动作的电机的结构相比,能够削减部件数量。(2) The damper device 8 includes one motor 52 that operates the upper blade 511 and the lower blade 512 . According to this configuration, the number of components can be reduced compared to a configuration in which a motor for operating the upper blade 511 and a motor for operating the lower blade 512 are provided separately.

(3)风门装置8相对于散热器5配置在空气流动方向的正前方。根据该结构,能够利用设置于散热器5的前方的空间来设置风门装置8。(3) The damper device 8 is arranged directly in front of the radiator 5 in the air flow direction. According to this configuration, the damper device 8 can be installed using the space provided in front of the radiator 5 .

(4)如图1所示,车辆C的上下方向Z上的格栅开口部2的宽度H11短于车辆C的上下方向Z上的风门装置8的下侧开口区域A13、A14的宽度H12。通过像该结构这样将格栅开口部2的宽度设定得短,能够减少取入导风管道4的空气的风量,因此能够提高车辆C的空气动力性能。(4) As shown in FIG. 1 , the width H11 of the grille opening 2 in the vertical direction Z of the vehicle C is shorter than the width H12 of the lower opening areas A13 and A14 of the damper device 8 in the vertical direction Z of the vehicle C. By setting the width of the grille opening 2 short as in this configuration, the volume of air taken into the air guide duct 4 can be reduced, and thus the aerodynamic performance of the vehicle C can be improved.

(5)在车辆C的起动开关70被进行了切断操作时,热系统ECU82使上侧叶片511和下侧叶片512位移到初始位置。根据该结构,每当起动开关70被进行了切断操作,都能够修正上侧叶片511和下侧叶片512各自的位置。(5) When the start switch 70 of the vehicle C is turned off, the thermal system ECU 82 displaces the upper vane 511 and the lower vane 512 to the initial positions. According to this configuration, the respective positions of the upper blade 511 and the lower blade 512 can be corrected every time the starter switch 70 is turned off.

(6)热系统ECU82根据散热器5和室外热交换器6各自的动作状态来控制上侧叶片511和下侧叶片512各自的开度。根据该结构,能够实现对应于散热器5和室外热交换器6各自的动作状态的更适当的空气的流动。(6) The thermal system ECU 82 controls the respective opening degrees of the upper vane 511 and the lower vane 512 according to the operating states of the radiator 5 and the outdoor heat exchanger 6 . According to this configuration, it is possible to realize a more appropriate flow of air corresponding to the respective operating states of the radiator 5 and the outdoor heat exchanger 6 .

<第二实施方式><Second Embodiment>

接着,对第二实施方式的车辆C进行说明。以下,以与第一实施方式的车辆C的不同点为中心进行说明。Next, a vehicle C according to the second embodiment will be described. Hereinafter, description will focus on differences from the vehicle C of the first embodiment.

作为热泵装置30的动作状况之一,考虑在外气温度低的环境下热泵装置30以制热模式动作的状况。在这样的状况中,假设从格栅开口部2进入的水附着于风门装置8时,由于附着的水冻结,风门装置8的各叶片511、512可能不能进行开闭动作。在这样的情况下,当因各叶片511、512不能进行开闭动作而检测到风门装置8异常时,车辆C的指示器点亮等,可能使驾驶者产生困惑。As one of the operating conditions of the heat pump device 30 , consider a situation where the heat pump device 30 operates in the heating mode in an environment where the outside air temperature is low. In such a situation, if water entering from the grille opening 2 adheres to the damper 8, the attached water freezes, and the blades 511, 512 of the damper 8 may not be able to open and close. In such a case, when an abnormality of the damper device 8 is detected because the vanes 511 and 512 cannot open and close, an indicator of the vehicle C lights up, which may confuse the driver.

另一方面,在风门装置8中,相对于配置于格栅开口部2的附近的下侧叶片512容易沾水,从格栅开口部2分开配置的上侧叶片511不容易沾水。考虑到该情况,在存在附着的水冻结的可能性的环境下,如果将下侧叶片512维持为闭状态,并仅使上侧叶片511进行开闭动作,即使下侧叶片512因沾水而冻结,也能够通过上侧开口区域A11、A12向室外热交换器6供给空气。因此,能够使热泵装置30以制热模式动作。具体而言,热系统ECU82如以下那样控制风门装置8。On the other hand, in damper device 8 , lower blades 512 arranged near grille opening 2 are more likely to get wet, and upper blades 511 arranged apart from grille opening 2 are less likely to get wet. In consideration of this, in an environment where there is a possibility that the adhered water may freeze, if the lower blade 512 is kept closed and only the upper blade 511 is opened and closed, even if the lower blade 512 is wetted by water, Even in case of freezing, air can be supplied to the outdoor heat exchanger 6 through the upper opening areas A11 and A12. Therefore, it is possible to operate the heat pump device 30 in the heating mode. Specifically, the thermal system ECU 82 controls the damper device 8 as follows.

本实施方式的热系统ECU82从空调ECU81获取热泵装置30的动作状态的信息。在图5所示的步骤S13的处理中,热系统ECU82判断是否为热泵装置30以制热模式动作且由外气温度传感器61检测出的外气温为冻结判定温度以下。冻结判定温度是用于判定在水附着于风门装置8时是否为该水可能冻结的外气温度的温度判定值,被预先设定为例如“5℃”。在判断为热泵装置30以制热模式动作且由外气温度传感器61检测出的外气温为冻结判定温度以下的情况下,热系统ECU82驱动电机52,以使得如图6所示那样上侧叶片511成为开状态,且下侧叶片512成为闭状态。The heat system ECU 82 of the present embodiment acquires information on the operating state of the heat pump device 30 from the air conditioner ECU 81 . In the process of step S13 shown in FIG. 5 , thermal system ECU 82 determines whether or not heat pump device 30 is operating in the heating mode and the outside air temperature detected by outside air temperature sensor 61 is below the freezing determination temperature. The freezing judgment temperature is a temperature judging value for judging whether or not the outside air temperature is at which water may freeze when water adheres to the damper device 8 , and is set in advance to, for example, "5°C". When it is judged that the heat pump device 30 is operating in the heating mode and the outside air temperature detected by the outside air temperature sensor 61 is below the freezing judgment temperature, the thermal system ECU 82 drives the motor 52 so that the upper blades as shown in FIG. 6 511 is in an open state, and the lower blade 512 is in a closed state.

根据以上说明的本实施方式的车辆C,能够进一步得到以下的(7)所示的作用和效果。According to the vehicle C of the present embodiment described above, the operation and effect shown in the following (7) can be further obtained.

(7)根据本实施方式的车辆C的结构,即使在风门装置8因沾水而容易冻结的环境下,也能够使热泵装置30以制热模式动作。因此,能够继续车室内的制热,从而能够确保车室内的舒适性。(7) According to the configuration of the vehicle C of the present embodiment, the heat pump device 30 can be operated in the heating mode even in an environment where the damper device 8 is likely to freeze due to water. Therefore, the heating of the vehicle interior can be continued, and the comfort of the vehicle interior can be ensured.

<第三实施方式><Third Embodiment>

接着,对第三实施方式的车辆C进行说明。以下,以与第一实施方式的车辆C的不同点为中心进行说明。Next, a vehicle C according to a third embodiment will be described. Hereinafter, description will focus on differences from the vehicle C of the first embodiment.

室外热交换器6通常构成为具有多个管和分别与这些管的两端部连结的箱。在室外热交换器6中,在各管的内部流动的制冷剂与在各管的外部流动的空气进行热交换。在由这样的结构构成的室外热交换器6中,当霜附着于管的表面时,相对于空气的传热面积实质上减少,因此热交换效率可能显著降低。因此,热泵装置30会以所谓的除霜模式动作,该除霜模式在霜附着于室外热交换器6的管的表面时融化该霜。在除霜模式中,例如以切断向室外热交换器6的空气的供给的状态使制冷剂在室外热交换器6循环。由此,能够通过制冷剂的热来融化附着于管的表面的霜。The outdoor heat exchanger 6 is generally constituted to have a plurality of tubes and tanks respectively connected to both ends of the tubes. In the outdoor heat exchanger 6, the refrigerant flowing inside each tube exchanges heat with the air flowing outside each tube. In the outdoor heat exchanger 6 constituted by such a structure, when frost adheres to the surface of the tubes, the heat transfer area with respect to the air is substantially reduced, and thus the heat exchange efficiency may be significantly reduced. Therefore, the heat pump device 30 operates in a so-called defrosting mode that melts frost when it adheres to the surface of the tubes of the outdoor heat exchanger 6 . In the defrosting mode, for example, the refrigerant circulates through the outdoor heat exchanger 6 with the supply of air to the outdoor heat exchanger 6 cut off. Thereby, frost adhering to the surface of the tube can be melted by the heat of the refrigerant.

另一方面,在除霜模式中,为了切断向室外热交换器6的空气的供给,将风门装置8的上侧叶片511和下侧叶片512都设为闭状态即可。但是,当将这些叶片511、512都设为闭状态时,不能向室外热交换器6供给空气,因此不能使热泵装置30以制热模式动作。即,不能进行车室内的制热,从而可能损害车室内的舒适性。On the other hand, in the defrosting mode, in order to cut off the supply of air to the outdoor heat exchanger 6, both the upper vane 511 and the lower vane 512 of the damper device 8 may be closed. However, when these vanes 511, 512 are both closed, air cannot be supplied to the outdoor heat exchanger 6, and therefore the heat pump device 30 cannot be operated in the heating mode. That is, heating of the vehicle interior cannot be performed, and the comfort of the vehicle interior may be impaired.

因此,在图5所示的步骤S13的处理中,本实施方式的热系统ECU82在从空调ECU81获取热泵装置30的动作状态的信息的基础上,判断为热泵装置30以除霜模式动作的情况下,以规定的时间间隔交替地执行以下的(b1)和(b2)所示的控制。Therefore, in the process of step S13 shown in FIG. 5 , thermal system ECU 82 of this embodiment determines that heat pump device 30 is operating in the defrosting mode after acquiring information on the operating state of heat pump device 30 from air conditioner ECU 81 . Next, the controls shown in (b1) and (b2) below are alternately executed at predetermined time intervals.

(b1)驱动电机52,以使得如图7(A)所示那样上侧叶片511成为开状态,且下侧叶片512成为闭状态。(b1) The motor 52 is driven so that the upper blade 511 is in the open state and the lower blade 512 is in the closed state as shown in FIG. 7(A) .

(b2)驱动电机52,以使得如图7(B)所示那样上侧叶片511成为闭状态,且下侧叶片512成为开状态。(b2) The motor 52 is driven so that the upper blade 511 is in the closed state and the lower blade 512 is in the open state as shown in FIG. 7(B) .

由此,在车辆C中,交替地切换与(b1)对应的第一状态和与(b2)对应的第二状态。Thus, in the vehicle C, the first state corresponding to (b1) and the second state corresponding to (b2) are alternately switched.

根据以上说明的本实施方式的车辆C,能够得到以下的(8)所示的作用和效果。According to the vehicle C of the present embodiment described above, the action and effect shown in (8) below can be obtained.

(8)在执行上述的(b1)的控制的情况下,向室外热交换器6的上部6a供给空气,因此,能够将该部分用作吸热器。另外,由于没有向室外热交换器6的下部6b供给空气,因此在该部分中能够通过制冷剂的热来融化附着的霜。即,上部6a作为吸热区域发挥功能,下部6b作为除霜区域发挥功能。另一方面,在执行了上述的(b2)的控制的情况下,由于向室外热交换器6的下部6b供给空气,因此能够将该部分用作吸热器。另外,由于没有向室外热交换器6的上部6a供给空气,因此在该部分中能够通过制冷剂的热来融化附着的霜。即,上部6a作为除霜区域发挥功能,下部6b作为吸热区域发挥功能。根据该结构,能够同时去除附着于室外热交换器6的上部6a和下部6b的霜,因此能够避免因霜的附着导致的室外热交换器6的性能的降低。另外,由于能够继续将室外热交换器6用作吸热器,因此车室内的连续制热成为可能。(8) When the above-mentioned control of (b1) is performed, air is supplied to the upper part 6a of the outdoor heat exchanger 6, so this part can be used as a heat absorber. Moreover, since air is not supplied to the lower part 6b of the outdoor heat exchanger 6, the frost attached to this part can be melt|melted by the heat of a refrigerant|coolant. That is, the upper part 6a functions as a heat absorption area, and the lower part 6b functions as a defrosting area. On the other hand, when the above-mentioned control of (b2) is performed, since air is supplied to the lower part 6b of the outdoor heat exchanger 6, this part can be used as a heat absorber. In addition, since air is not supplied to the upper part 6a of the outdoor heat exchanger 6, the frost adhering to this part can be melted by the heat of a refrigerant|coolant. That is, the upper part 6a functions as a defrosting area, and the lower part 6b functions as a heat absorbing area. According to this structure, since the frost adhered to the upper part 6a and the lower part 6b of the outdoor heat exchanger 6 can be removed simultaneously, the fall of the performance of the outdoor heat exchanger 6 by the adhesion of frost can be avoided. In addition, since the outdoor heat exchanger 6 can continue to be used as a heat absorber, continuous heating of the vehicle interior becomes possible.

<第四实施方式><Fourth Embodiment>

接着,对第四实施方式的车辆C进行说明。以下,以与第三实施方式的车辆C的不同点为中心进行说明。Next, a vehicle C according to a fourth embodiment will be described. Hereinafter, description will focus on differences from the vehicle C of the third embodiment.

当热泵装置30以除霜模式驱动时,因霜融化而生成的水积留在室外热交换器6的表面。当该水冻结时,室外热交换器6的热交换效率可能显著地降低,或在室外热交换器6产生冻结破裂。因此,希望尽可能地除去积留于室外热交换器6的表面的水。When the heat pump device 30 is driven in the defrosting mode, water generated by melting frost remains on the surface of the outdoor heat exchanger 6 . When this water freezes, the heat exchange efficiency of the outdoor heat exchanger 6 may be significantly lowered, or freezing crack may occur in the outdoor heat exchanger 6 . Therefore, it is desirable to remove the water accumulated on the surface of the outdoor heat exchanger 6 as much as possible.

因此,本实施方式的热系统ECU82在热泵装置30以除霜模式动作之后,进一步执行从室外热交换器6的表面去除水的排水模式。Therefore, the heat system ECU 82 of the present embodiment further executes the drain mode for removing water from the surface of the outdoor heat exchanger 6 after the heat pump device 30 operates in the defrosting mode.

具体而言,作为排水模式,热系统ECU82以规定的时间间隔交替地执行上述的(b1)和(b2)所示的控制。由此,例如在从上述的(b1)的控制切换至上述的(b2)的控制时,室外热交换器6的下部6b从没有空气流动的状态切换至空气流动的状态。因此,能够使在室外热交换器6的下部6b流动的空气的风量急剧地变化。通过该空气的风量的急剧地变化,吹走积留于室外热交换器6的下部6b的水。另外,在从上述的(b2)的控制切换至上述的(b1)的控制时,吹走积留于室外热交换器6的上部6a的水。作为结果,能够去除积留于室外热交换器6的水。Specifically, as the drainage mode, thermal system ECU 82 alternately executes the controls shown in (b1) and (b2) above at predetermined time intervals. Thus, for example, when switching from the control of (b1) above to the control of (b2) above, the lower portion 6b of the outdoor heat exchanger 6 is switched from a state where air does not flow to a state where air flows. Therefore, the air volume of the air flowing through the lower portion 6b of the outdoor heat exchanger 6 can be changed rapidly. This sudden change in air volume blows off the water accumulated in the lower portion 6 b of the outdoor heat exchanger 6 . Moreover, when switching from the control of (b2) mentioned above to the control of (b1) mentioned above, the water accumulated in the upper part 6a of the outdoor heat exchanger 6 is blown away. As a result, water accumulated in the outdoor heat exchanger 6 can be removed.

根据以上说明的本实施方式的车辆C,能够得到以下的(9)所示的作用和效果。According to the vehicle C of the present embodiment described above, the action and effect shown in (9) below can be obtained.

(9)热系统ECU82在热泵装置30以除霜模式动作之后,执行使通过室外热交换器6的上部6a和下部6b的空气的风量急剧地变化的排水模式,由此去除积留于室外热交换器6的水。由此,能够去除因执行除霜模式而积留于室外热交换器6的水,因此能够避免室外热交换器6的热交换效率的降低、冻结破裂等。(9) After the heat pump device 30 operates in the defrosting mode, the thermal system ECU 82 executes a drainage mode in which the air volume of the air passing through the upper part 6 a and the lower part 6 b of the outdoor heat exchanger 6 is changed rapidly, thereby removing heat accumulated in the outdoor. Exchanger 6 water. Thereby, the water accumulated in the outdoor heat exchanger 6 due to execution of the defrosting mode can be removed, so that a decrease in the heat exchange efficiency of the outdoor heat exchanger 6 , freezing cracks, and the like can be avoided.

<第五实施方式><Fifth Embodiment>

接着,对第五实施方式的车辆C进行说明。以下,以与第一实施方式的车辆C的不同点为中心进行说明。Next, a vehicle C according to a fifth embodiment will be described. Hereinafter, description will focus on differences from the vehicle C of the first embodiment.

如图8所示,在本实施方式的车辆C中,散热器5与室外热交换器6经由外翅片9热连结。即,能够经由外翅片9在散热器5与室外热交换器6之间进行热交换。由此,例如在室外热交换器6作为吸热器动作的情况下,能够将散热器5的废热经由外翅片9传递至室外热交换器6,因此能够提高作为车辆C整体的热效率。作为结果,能够提高车辆C的电力经济性。As shown in FIG. 8 , in vehicle C according to the present embodiment, radiator 5 and outdoor heat exchanger 6 are thermally connected via outer fins 9 . That is, heat exchange can be performed between the radiator 5 and the outdoor heat exchanger 6 via the outer fins 9 . Thus, for example, when the outdoor heat exchanger 6 operates as a heat sink, the waste heat of the radiator 5 can be transferred to the outdoor heat exchanger 6 via the outer fins 9, so that the thermal efficiency of the vehicle C as a whole can be improved. As a result, the electric power economy of the vehicle C can be improved.

另一方面,在将散热器5的废热向室外热交换器6传递时,将风门装置8的上侧叶片511和下侧叶片512都设为闭状态是有效的。由此,散热器5不会被空气冷却,因此能够效率良好地将散热器5的废热传递至室外热交换器6。但是,仅像这样将散热器5的废热传递至室外热交换器6可能无法满足空调装置40的制热要求。On the other hand, when transferring the waste heat of the radiator 5 to the outdoor heat exchanger 6, it is effective to make both the upper blade 511 and the lower blade 512 of the damper device 8 into the closed state. Accordingly, since the radiator 5 is not cooled by the air, the waste heat of the radiator 5 can be efficiently transferred to the outdoor heat exchanger 6 . However, merely transferring the waste heat from the radiator 5 to the outdoor heat exchanger 6 may not be able to meet the heating requirement of the air conditioner 40 .

具体而言,如图9所示,散热器5构成为从其下部5b朝向上部5a而冷却水U字状地流动。在该情况下,散热器5的热经由外翅片9向室外热交换器6传递的结果是,在散热器5的内部流动的冷却水的温度随着朝向下游而降低。即,与散热器5的下部5b的温度相比,其上部5a的温度变低。因此,室外热交换器6能够从散热器5的下部5b吸收所需的热量,但同时也可能无法从散热器5的上部5a吸收所需的热量。由此,作为室外热交换器6整体的吸热量不足,且不能通过空调装置40充分地加热向车室内吹送的空气,因此难以适当地执行车室内的制热,可能损害车室内的舒适性。Specifically, as shown in FIG. 9 , the radiator 5 is configured such that cooling water flows in a U-shape from the lower portion 5 b toward the upper portion 5 a. In this case, as the heat of the radiator 5 is transferred to the outdoor heat exchanger 6 via the outer fins 9 , the temperature of the cooling water flowing inside the radiator 5 decreases as it goes downstream. That is, the temperature of the upper part 5a of the radiator 5 becomes lower than the temperature of the lower part 5b of the radiator 5 . Therefore, the outdoor heat exchanger 6 can absorb the required heat from the lower part 5b of the radiator 5, but may not be able to absorb the required heat from the upper part 5a of the radiator 5 at the same time. As a result, the heat absorbed by the outdoor heat exchanger 6 as a whole is insufficient, and the air blown into the vehicle interior cannot be sufficiently heated by the air conditioner 40. Therefore, it is difficult to perform proper heating of the vehicle interior, which may impair the comfort of the vehicle interior. .

因此,在仅经由外翅片9向室外热交换器6传递散热器5的热无法满足室外热交换器6的吸热量的情况下,本实施方式的热系统ECU82驱动电机52,以使得如图8所示上侧叶片511成为开状态,且下侧叶片512成为闭状态。由此,在室外热交换器6中,能够在其下部6b经由外翅片9吸收散热器5的废热,并且能够在其上部6a从空气吸收不够的量的热量。作为结果,能够确保作为室外热交换器6的整体所需的吸热量。Therefore, when the heat absorbed by the outdoor heat exchanger 6 cannot be satisfied only by transferring the heat of the radiator 5 to the outdoor heat exchanger 6 through the outer fins 9, the thermal system ECU 82 of this embodiment drives the motor 52 so that As shown in FIG. 8 , the upper blade 511 is in the open state, and the lower blade 512 is in the closed state. Thereby, in the outdoor heat exchanger 6, the waste heat of the radiator 5 can be absorbed in the lower part 6b via the outer fin 9, and the heat of the insufficient amount can be absorbed from the air in the upper part 6a. As a result, it is possible to ensure the required heat absorption amount of the outdoor heat exchanger 6 as a whole.

根据以上说明的本实施方式的车辆C,能够得到以下的(10)所示的作用和效果。According to the vehicle C of the present embodiment described above, the operation and effect shown in the following (10) can be obtained.

(10)在室外热交换器6作为经由外翅片9使制冷剂吸收散热器5的热的吸热器动作时,热系统ECU82将上侧叶片511设定为开状态,并将下侧叶片512设定为闭状态。根据该结构,能够更可靠地确保室外热交换器6的吸热量,因此能够适当地进行车室内的制热。由此,能够确保车室内的舒适性。(10) When the outdoor heat exchanger 6 operates as a heat absorber that allows the refrigerant to absorb the heat of the radiator 5 via the outer fins 9 , the thermal system ECU 82 sets the upper fins 511 to the open state, and turns the lower fins 511 to the open state. 512 is set to the closed state. According to this structure, since the heat absorption amount of the outdoor heat exchanger 6 can be ensured more reliably, the heating of a vehicle interior can be performed suitably. Accordingly, comfort in the vehicle interior can be ensured.

<第六实施方式><Sixth Embodiment>

接着,对第六实施方式的车辆C进行说明。以下,以与第一实施方式的车辆C的不同点为中心进行说明。Next, a vehicle C according to a sixth embodiment will be described. Hereinafter, description will focus on differences from the vehicle C of the first embodiment.

如图10所示,本实施方式的车辆C搭载了多功能热交换器10来代替散热器5,并且搭载了散热器11来代替室外热交换器6。As shown in FIG. 10 , a vehicle C according to the present embodiment is equipped with a multifunctional heat exchanger 10 instead of the radiator 5 and a radiator 11 instead of the outdoor heat exchanger 6 .

多功能热交换器10在其下部具有第一热交换部10A,在其上部具有第二热交换部10B。第一热交换部10A被用作上述的热泵装置30的室外热交换器6。第一热交换部10A与风门装置8的下侧开口区域A13、A14相对地配置。用于冷却电池222的冷却水在第二热交换部10B的内部流动。第二热交换部10B通过使在其内部流动的冷却水与在其外部流动的空气进行热交换来冷却冷却水。第二热交换部10B与风门装置8的上侧开口区域A11、A12相对地配置。The multifunctional heat exchanger 10 has a first heat exchange portion 10A at its lower portion and a second heat exchange portion 10B at its upper portion. The first heat exchange unit 10A is used as the outdoor heat exchanger 6 of the heat pump device 30 described above. The first heat exchange portion 10A is arranged to face the lower opening areas A13 and A14 of the damper device 8 . Cooling water for cooling the battery 222 flows inside the second heat exchange portion 10B. The second heat exchange portion 10B cools the cooling water by exchanging heat between the cooling water flowing inside and the air flowing outside it. The second heat exchange portion 10B is arranged to face the upper opening areas A11 and A12 of the damper device 8 .

用于冷却电机220的冷却水在散热器11的内部流动。散热器11通过使在其内部流动的冷却水与在其外部流动的空气进行热交换来冷却冷却水。散热器11的上部11a以与风门装置8的上侧开口区域A11、A12相对的方式配置。散热器11的下部11b以与下侧开口区域A13、A14相对的方式配置。Cooling water for cooling the motor 220 flows inside the radiator 11 . The radiator 11 cools the cooling water by exchanging heat between the cooling water flowing inside it and the air flowing outside it. The upper portion 11 a of the radiator 11 is disposed so as to face the upper opening areas A11 and A12 of the damper device 8 . The lower part 11b of the heat sink 11 is disposed so as to face the lower opening areas A13 and A14.

这样,在本实施方式的车辆C中,独立地设置用于冷却电机220的冷却回路和用于冷却电池222的冷却回路。在散热器11中,能够冷却温度高于第二热交换部10B的冷却水。在本实施方式中,电机220相当于第一发热体,电池222相当于第二发热体。In this way, in vehicle C of the present embodiment, the cooling circuit for cooling motor 220 and the cooling circuit for cooling battery 222 are provided independently. In the radiator 11, cooling water whose temperature is higher than that of the second heat exchange portion 10B can be cooled. In this embodiment, the motor 220 corresponds to the first heating element, and the battery 222 corresponds to the second heating element.

在没有被要求进行电池222的冷却的情况下,热系统ECU82驱动电机52,以使得如图10所示那样上侧叶片511成为闭状态,且下侧叶片512成为开状态。由此,成为从格栅开口部2导入的空气仅向多功能热交换器10的第一热交换部10A流动,与空气向第一热交换部10A和第二热交换部10B这双方流动的情况相比,能够增加向第一热交换部10A流动的空气的风量。When cooling of battery 222 is not requested, thermal system ECU 82 drives motor 52 so that upper blade 511 is closed and lower blade 512 is opened as shown in FIG. 10 . Thus, the air introduced from the grill opening 2 flows only to the first heat exchange portion 10A of the multifunctional heat exchanger 10, and the air flows to both the first heat exchange portion 10A and the second heat exchange portion 10B. Compared with the case, it is possible to increase the air volume of the air flowing into the first heat exchange portion 10A.

此外,在热泵装置30停止的情况下,也可以是热系统ECU82驱动电机52,以使得上侧叶片511成为开状态,且下侧叶片512成为闭状态。In addition, when the heat pump device 30 is stopped, the thermal system ECU 82 may drive the motor 52 so that the upper vane 511 is in the open state and the lower vane 512 is in the closed state.

根据以上说明的本实施方式的车辆C,能够得到以下的(11)所示的作用和效果。According to the vehicle C of the present embodiment described above, the action and effect shown in the following (11) can be obtained.

(11)在没有被要求进行电池222的冷却的情况下,热系统ECU82将下侧叶片512设定为开状态,并将上侧叶片511设定为闭状态。根据该结构,不向不需要与空气进行热交换的多功能热交换器10的第一热交换部10A供给空气,并且能够将与之对应的量向多功能热交换器10的第二热交换部10B供给而增加空气的风量。因此,在例如第一热交换部10A在热泵装置30中被用作冷凝器的情况下,能够更可靠地冷却在第一热交换部10A流动的制冷剂,因此能够提高制冷剂的冷却效率。因此,将第一热交换部10A小型化等成为可能。(11) When cooling of the battery 222 is not requested, the thermal system ECU 82 sets the lower vane 512 to the open state and sets the upper vane 511 to the closed state. According to this configuration, air is not supplied to the first heat exchange portion 10A of the multifunctional heat exchanger 10 that does not need to exchange heat with air, and an amount corresponding to it can be exchanged with the second heat exchange portion of the multifunctional heat exchanger 10. Part 10B supplies and increases the volume of air. Therefore, for example, when the first heat exchange unit 10A is used as a condenser in the heat pump device 30 , the refrigerant flowing through the first heat exchange unit 10A can be cooled more reliably, thereby improving the cooling efficiency of the refrigerant. Therefore, it becomes possible to downsize the first heat exchange part 10A and the like.

<其他实施方式><Other Embodiments>

此外,上述实施方式还能够通过以下方式来实施。In addition, the above-described embodiment can also be implemented in the following manner.

也可以对第三实施方式的车辆C应用第五实施方式的车辆C的结构、即散热器5与室外热交换器6经由外翅片9热连结的结构。根据该结构,热泵装置30在执行去除附着于室外热交换器6的表面的霜的除霜模式时,能够代替利用在室外热交换器6的内部循环的制冷剂的热这样的方法,而使用利用从散热器5经由外翅片9向室外热交换器6传递的热这样的方法。The structure of the vehicle C of the fifth embodiment, that is, the structure in which the radiator 5 and the outdoor heat exchanger 6 are thermally connected via the outer fins 9 can also be applied to the vehicle C of the third embodiment. According to this configuration, when the heat pump device 30 executes the defrosting mode for removing frost adhering to the surface of the outdoor heat exchanger 6 , instead of utilizing the heat of the refrigerant circulating inside the outdoor heat exchanger 6 , it can be used. A method of utilizing heat transferred from the radiator 5 to the outdoor heat exchanger 6 via the outer fins 9 .

风门装置8不限于具有上侧叶片511和下侧叶片512这两个开闭部,也可以具有三个以上的开闭部。The damper device 8 is not limited to having two opening and closing sections of the upper blade 511 and the lower blade 512 , but may have three or more opening and closing sections.

风门装置8也可以配置在散热器5与室外热交换器6之间,或相对于室外热交换器6配置在空气流动方向的正后方。The damper device 8 may be arranged between the radiator 5 and the outdoor heat exchanger 6 , or may be arranged directly behind the outdoor heat exchanger 6 in the air flow direction.

第一实施方式~第五实施方式的车辆C中,作为使向散热器5和室外热交换器6供给的空气的风量变化的开闭装置,使用了配置于散热器5的前方的风门装置8。取而代之,也可以在送风机7的风扇罩设置具有与风门装置8相同或类似的功能的风门机构。在该情况下,设置于送风机7的风门机构相当于开闭装置。关于第六实施方式的车辆C也相同。In the vehicles C according to the first to fifth embodiments, the damper device 8 arranged in front of the radiator 5 is used as an opening and closing device for changing the volume of air supplied to the radiator 5 and the outdoor heat exchanger 6 . . Instead, a damper mechanism having the same or similar function as that of the damper device 8 may be provided on the fan cover of the air blower 7 .
