The present invention relates to a cooling / heating device for a rear passenger side of a vehicle using a thermoelectric module capable of selectively attaching / will be.

BACKGROUND ART [0002] In general, an air conditioner for a vehicle is generally applied to a van, an RV vehicle, or an SUV vehicle, which is large enough to allow indoor air to be cooled and heated comfortably only by an air conditioning system. And is installed in a closed space to constitute a dual air conditioner.

There are two types of air conditioners for automobiles. The air conditioners can be classified into two types: an evaporator is used only for cooling and an evaporator and a heater core are used for cooling and heating.

However, in the case of the above-mentioned rear air-conditioning system, since the evaporator or the heater core must be installed in the interior, the volume of the evaporator or the heater core must be increased.

In order to solve the above-mentioned problem, a device for directly heating and heating an electric seat or a rear seat using a thermoelectric module has been developed. For example, Japanese Patent Laid-Open No. 2000-060681 discloses a seat heating and cooling apparatus using a thermoelectric module, Will now be described with reference to Fig.

The sheet heating and cooling apparatus 10 using the thermoelectric module is provided with a thermoelectric module 20 in the sheet 1 and a heat radiator 30 on one side of the thermoelectric module 20 And a heat pipe (40) is installed on the other side.

A heat dissipation path 2 is formed in the sheet 1 on which the heat dissipating member 30 is installed and a fan 3 is installed in the heat dissipating path 2. [

For example, the thermoelectric module 20 has an endothermic function at one side and a heat-radiating function at the other side according to the current flow direction, and the endothermic / So that the heat pipe 40 can be heated or cooled.

The thermoelectric module 20 may cool the heat pipe 40 by absorbing the heat to the heat pipe 40 to cool the sheet 1, And the heat discharging body 30 is heated because the heat discharging body 30 is heated.

At this time, since the efficiency of the heat absorbing side is improved as the heated heat radiator 30 is cooled more rapidly, the fan 3 installed in the heat radiating passage 2 is operated to improve the cooling performance, So that the heat discharging body 30 is cooled. In this process, the heated air (waste heat) while being exchanged with the heat discharging body 30 is discharged to the passenger compartment.

However, in the related art, waste heat generated by heat exchange with the heat discharging body 30 at the time of cooling / heating (operation) of the thermoelectric module 20 is discharged to the inside of the vehicle through the heat discharging passage 2, There is a problem that the cooling and heating efficiency and performance of the indoor are deteriorated.

FIG. 2 is a perspective view showing a rear heating unit for a vehicle rear seat using the thermoelectric module according to the present invention, FIG. 3 is a sectional view showing a rear heating unit for a vehicle rear seat using the thermoelectric module according to the present invention, Fig.

As shown in the figure, the rear heating / cooling unit 100 using the thermoelectric module according to the present invention is installed in the armrest 110 provided on the side of the seat 101 of the vehicle, A first blowing fan 113, and a second blowing fan 116. The heat-radiating fins 130, 131,

First, the armrest 110 is installed at the center of the seat 101 of the vehicle, and the interior of the armrest 110 is divided into two parts based on the thermoelectric module 120 to be installed therein.

At this time, in addition to the thermoelectric module 120, a separation wall 111 may be further formed inside the armrest 110 to divide the inside of the armrest 110.

The separation wall 111 is located at both ends of the thermoelectric module 120 as shown in the figure but the formation position of the separation wall 111 is changed according to the size or position of the thermoelectric module 120 .

The thermoelectric module 120 and the separating wall 111 are preferably disposed at positions that divide the interior of the armrest 110 up and down.

That is, the thermoelectric module 120 is horizontally installed inside the armrest 110, and the inside of the armrest 110 is divided into upper and lower parts by the thermoelectric module 120.

An air supply passageway 112 for circulating the passenger compartment air is formed in the upper portion of the armrest 110 with reference to the thermoelectric module 120 and the partition wall 111, An air discharge passage 115 for discharging air to the outside through a trunk is formed.

Meanwhile, the thermoelectric module 120 and the separating wall 111 may be installed at positions where the inside of the armrest 110 is divided into left and right sides.

Radiating fins 130 and 131 are installed on both sides of the thermoelectric module 120. The heat dissipation fin 130 installed on the upper side of the thermoelectric module 120 is positioned in the air supply passage 112 and the heat dissipation fin 131 installed on the lower side of the thermoelectric module 120 And is located in the air discharge passage 115.

The heat radiating fins 130 and 131 are formed by bending a thin plate material in a zigzag shape.

For reference, the thermoelectric module 120 has an endothermic action on one side and a heat radiation function on the other side according to the flow direction of the current.

The thermoelectric module 120 can heat and cool the air passing through the air supply passage 112 of the armrest 110 because heat can be absorbed and radiated simultaneously by switching the polarities of the currents. To the front side and the upper side of the seats 101, so that the entire seats 101 can be cooled and heated.

That is, if the polarity of the current applied to the thermoelectric module 120 is changed, the heat radiating fin 130 located on the air supply passage 112 side of the armrest 110 can be cooled or hot, . Therefore, the occupant can select the cooling and heating by the air conditioner control switch (not shown).

A first blowing fan 113 is installed in the air supply passage 112 which is one side of the thermoelectric module 120 and a second blowing fan 113 is installed in the air discharge passage 115 on the other side of the thermoelectric module 120. [ 2 blowing fan 116 is installed.

The first blowing fan 113 installed in the air supply passage 112 sucks in the room air and exchanges heat with one radiating fin 130 of the thermoelectric module 120, do.

The inlet 112a of the air supply passage 112 is formed to pass through the rear end of the armrest 110 adjacent to the back 101a of the seat 101 and the outlet 112b is connected to the inlet Which is the opposite side of the seat back 112a, and is configured to discharge air in the front side and the upward direction of the seat back 101. [

At this time, the first blowing fan 113 may be installed on the upstream or downstream side of the radiating fin 130 located on the air supply passage 112. In the drawing, the first blowing fan 113 is provided on the upstream side of the radiating fin 130.

Accordingly, when the first blowing fan 113 is activated, the in-vehicle air is sucked through the inlet 112a of the air supply passage 112, and the sucked air is sucked through the inlet 112a of the air supply passage 112, And is discharged to the front side and the upper side of the back side 101 through the outlet 112b of the air supply path 112 to cool and heat the entire back side 101 do.

The second air blowing fan 116 installed in the air exhaust passage 115 sucks indoor air and exchanges heat with the other radiating fins 131 of the thermoelectric module 120, and then discharges the air to the trunk. The air discharged through the trunk is discharged to the outside through a hole (not shown) formed in the bottom of the trunk.

The inlet 115a of the air discharge passage 115 is formed through the front end of the armrest 110 in the same direction as the outlet 112b of the air supply passage 112, Is formed to communicate with the trunk at the rear end of the armrest (110).

At this time, the second blowing fan 116 may be installed on the upstream or downstream side of the radiating fin 131 located on the air discharge passage 115. In the drawing, the second blowing fan 116 is provided on the downstream side of the radiating fin 131.

Accordingly, when the second blowing fan 116 is operated, the in-vehicle air is sucked through the inlet 115a of the air discharge passage 115, and the sucked air is sucked through the inlet 115a of the air discharge passage 115, Exchanged with the heat-radiating fins 131 to be cooled or heated, discharged to the trunk through the outlet 115b of the air discharge passage 115, and then discharged to the outside through holes formed in the trunk.

The air required for cooling and heating the entire back surface 101 is heat-exchanged with the upper heat radiating fin 130 of the thermoelectric module 120 located on the air supply passage 112, So that air (waste heat) unnecessary for cooling and heating is discharged through the trunk to the outside through heat exchange with the lower radiating fins 131 of the thermoelectric module 120 located on the air discharge passage 115 Thereby improving the efficiency of the thermoelectric module 120 and improving the cooling and heating performance of the interior of the vehicle.

It is preferable that the air passing through the heat radiating fins 130 and 131 provided on both sides of the thermoelectric module 120 pass through in opposite directions.

For example, in the cooling mode, the air passing through the heat radiating fin 130 installed on the upper side of the thermoelectric module 120 gradually decreases in temperature due to the endothermic action of the thermoelectric module 120, The temperature of the air passing through the radiating fins 131 provided on the lower side of the thermoelectric module 120 is gradually increased due to the heat dissipation action of the thermoelectric module 120 and the temperature deviation between the both sides of the thermoelectric module 120 is uniform do. As such, the temperature difference between the two sides of the thermoelectric module 120 becomes uniform, thereby increasing the efficiency of the thermoelectric module 120.

It is effective that the thermoelement module 120 is divided into a plurality of thermoelement modules 120 rather than one thermoelement module 120 and arranged in series along the wind direction inside the armrests 110.

That is, since the operating temperature of the plurality of thermoelectric element modules 120 varies depending on the position, the thermoelectric element module 120 optimized for operating temperature conditions and temperature differences can be used according to each position. Since the efficiency of the thermoelectric module 120 varies greatly depending on the operating temperature and the temperature difference, the efficiency of the thermoelectric module 120 can be increased by optimizing the thermoelectric module 120 according to each position, There are advantages.

In addition, since the temperature difference between the plurality of thermoelectric element modules 120 is constant, the stability of the thermoelectric element module 120 can be improved during the design of the thermoelectric element module 120, thereby enhancing the convenience of manufacture.
