This application claims priority to a patent application filed with the State Intellectual Property Office of China on October 19, 2022, with application number 202211289974.7 and invention name “Heat Exchange Equipment”.

Technical Field

The present application relates to the technical field related to heat exchange equipment, and in particular, to a heat exchange equipment.

Background technique

Heat exchange equipment has the function of temperature regulation, such as air conditioners. During the use of air conditioners, especially when the integrated air conditioner is in heating mode in winter, the outdoor condenser will produce condensed water through heat exchange or high-temperature defrosting and ice melting, which will slide down the fins and gather in the chassis. Due to usage requirements, the condensed water on the outdoor side of the integrated air conditioner does not need to be installed with water pipes and directly discharged, dripping onto the ground or buildings. When the outdoor ambient temperature is below 0°, the condensed water accumulated in the chassis will freeze, which may damage the high-speed running fan blades and the water rings set on the fan blades, causing the air conditioner to fail to work normally.

Although some air conditioners on the market currently have the technical effect of melting condensed water and supplying liquid to the evaporator to form steam so that the steam can achieve humidification, the amount of condensed water consumed by the steam is limited, and there is still the problem of condensed water needing to be discharged.

In the present application, unless otherwise specified, the directional words used, such as "up, down, top, bottom", usually refer to the directions shown in the drawings, or to the components themselves in the vertical, perpendicular or gravity direction; similarly, for ease of understanding and description, "inside and outside" refer to the inside and outside relative to the outline of each component itself, but the above-mentioned directional words are not used to limit the present application.

In order to solve the problems in the prior art, the present application provides a heat exchange device. The heat exchange device can be used in the industrial field or in the household field to achieve temperature regulation.

Specifically, the heat exchange device is an air conditioner.

In the present application, the air conditioner is an integrated air conditioner.

It should be noted that when the integrated air conditioner is used in the heating mode in winter, the outdoor condenser produces condensed water through heat exchange or high-temperature defrosting and ice melting, and the condensed water enters the water collection structure 101 of the air conditioner shell 10 to achieve the effect of collecting condensed water.

Embodiment 1

As shown in Figures 1 to 18, the heat exchange device includes a shell 10, an evaporator 40 and a liquid storage tank 20. The shell 10 has a water collecting structure 101, which is used to collect condensed water. The evaporator 40 is arranged in the shell 10. At least a portion of the water collecting structure 101 is connected to the inlet 201 of the liquid storage tank 20. At least one outlet of the liquid storage tank 20 supplies condensed water to the evaporator 40 for realizing a humidification function.

Specifically, the heat exchange equipment of the present application collects the condensed water generated during use through the water collecting structure 101, and supplies the condensed water to the evaporator 40, and evaporates and consumes the condensed water through the evaporator 40, so as to consume the condensed water and humidify the air at the same time; the present application is also provided with a liquid storage tank 20 to collect excess condensed water, and supplies liquid to the evaporator 40 through the liquid storage tank 20 or collects condensed water through the liquid storage tank 20 to discharge the condensed water in a centralized manner, thereby realizing centralized treatment of the condensed water and avoiding arbitrary discharge of condensed water to affect environmental protection.

In this embodiment, the water collection structure 101 includes a water collection tank 1011, through which condensed water is collected. The water collection structure 101 also includes a water pump 50 and a delivery pipeline 70. The water pump 50 transfers the condensed water in the water collection tank 1011 to the liquid storage tank 20 via the delivery pipeline 70.

It should be noted that when the temperature is too low and the condensed water freezes inside the water collection tank 1011 of the water collection structure 101, the heating element 60 provided in the water collection tank 1011 can be used to heat and melt the ice so that the condensed water remains liquid. The water pump 50 is provided with a float level switch 510. When the heating element 60 is heated to melt the ice to form condensed water, the float level switch 510 controls the water pump 50 to work. Under the drive of the water pump 50, the condensed water can be transported to the inside of the liquid storage tank 20 through the transport pipeline 70. The heating element 60 is an electric heater, such as an electric heating wire, an electric heating rod, and other structural members with heating functions.

In this embodiment, the shell 10 has a chassis with a water collecting tank 1011 formed on the chassis, the water pump 50 and the water collecting tank 1011 are arranged on a side of the shell 10 away from the evaporator 40, and the water pump 50 is located at a corner of the shell 10, and the liquid storage tank 20 and the water pump 50 are located in the diagonal direction of the shell 10.

Since the water collecting tank 1011 for collecting condensed water is some distance away from the evaporator 40, the condensed water is transported to the liquid storage tank 20 by setting up a water pump 50 and a delivery pipeline 70. The water pump 50 is located at the corner of the shell 10 to provide power for the condensed water to flow inside the delivery pipeline 70. The above-mentioned layout is conducive to the flow of condensed water and enhances the collection efficiency of condensed water.

Of course, the arrangement position of the water pump 50 is not limited to being arranged at the corner of the housing 10, but can also be arranged at other positions inside the housing 10, so as to provide power.

It should be noted that the corner of the housing 10 is formed by connecting two side surfaces of the chassis of the housing 10 .

In this embodiment, at least a portion of the inner surface of the bottom plate extends obliquely downward in a direction away from the evaporator 40 , so that the condensed water on the side where the evaporator 40 is located flows back into the water collecting tank 1011 .

As shown in FIG. 1 to FIG. 4 , a drain valve 1040 is further provided in the water collection tank 1011 to control whether the condensed water inside the water collection tank 1011 is discharged to the external environment by controlling the on-off of the drain valve 1040 .

Specifically, a rain detection device is provided on the shell 10 for detecting whether it is raining in the external environment and sending a drainage signal when rain is detected. The rain detection device is connected to the drainage valve 1040 so as to open the drainage when the drainage valve 1040 receives the drainage signal.

In this embodiment, the rain detection device is a rain sensor.

In this embodiment, the water collecting tank 1011 has different depth areas. As the condensed water in the deep area is pumped out, the condensed water in the shallow area will be replenished into the deep area. The liquid inlet of the delivery pipeline 70 is connected to the deepest area of the water collecting tank 1011 of the chassis to ensure that the condensed water can be fully transmitted.

As shown in Figures 1, 2 and 7, the delivery pipeline 70 includes a first section 701, a second section 702 and a third section 703 connected in sequence, the first section 701 extends along the side of the shell 10, the third section 703 is arranged along the height direction of the shell 10, and the liquid outlet of the third section 703 is located at the top of the liquid storage tank 20.

Specifically, a segmented delivery pipeline 70 is used to achieve the delivery of condensed water, wherein the first section 701 and the second section 702 are bent, and the first section 701 and the second section 702 both extend along two adjacent sides of the shell 10, wherein the first section 701 extends from the pump body toward the evaporator 40, and the second section 702 extends toward the liquid storage tank 20.

In this embodiment, the specific angles of the first section 701 and the second section 702 can be adaptively set according to installation requirements. The first section 701 and the second section 702 can be set at a right angle.

In this embodiment, a liquid inlet is provided at one end of the first section 701 away from the second section 702 .

It should be noted that the first section 701 is used to connect to the water pump 50, the second section 702 is used to transmit liquid in the direction of the liquid storage tank 20, and the third section 703 is used to transport the liquid to the top of the liquid storage tank 20. The three-section setting is used to transmit liquid to improve the output efficiency of the liquid.

In this embodiment, the delivery pipeline 70 is made of silicone rubber and can be used at a low temperature of -30°. To ensure that there is no ice or blockage in the pipe, the outer surface of the delivery pipeline 70 is covered with a thermal insulation sponge with a thickness of not less than 9 mm.

As shown in Figures 10 to 15, the liquid storage tank 20 has a primary cavity 202 and a secondary cavity 203 that are connected to each other. The inlet 201 of the liquid storage tank 20 is connected to the primary cavity 202. The primary cavity 202 is provided with a first outlet 204. The first outlet 204 connected to the primary cavity 202 is used to supply condensed water to the evaporator 40.

Specifically, a first outlet 204 for providing condensed water to the evaporator 40 is provided on the primary cavity 202. After the condensed water enters the primary cavity 202, the condensed water can flow from the first outlet 204 to the evaporator 40 to achieve a humidification effect.

Furthermore, in order to achieve controllability of the humidification effect, the liquid storage tank 20 further includes a first valve 80, which is disposed at the first outlet 204 to adjust the on-off state between the primary chamber 202 and the evaporator 40. The first valve 80 is controlled to control whether humidification is performed.

In this embodiment, the distance h between the first outlet 204 and the bottom surface of the first-stage cavity 202 is 3-5 mm, and can be specifically 3 mm, 3.5 mm, 4 mm, 4.5 mm, or 5 mm.

It should be noted that the on/off state of the first valve 80 can be remotely controlled, or the on/off state of the first valve 80 can be manually controlled. The first valve 80 is a solenoid valve.

In this embodiment, the volume of the primary cavity 202 is smaller than that of the secondary cavity 203 . The secondary cavity 203 is used to store condensed water. Two different implementations are provided according to different structures of the liquid storage tank 20 .

In the specific implementation shown in Figures 10 to 15, a partial area of the liquid storage tank 20 encloses a primary cavity 202, and another part of the liquid storage tank 20 encloses a secondary cavity 203. The height of the liquid storage tank 20 enclosing the secondary cavity 203 is greater than the height of the liquid storage tank 20 enclosing the primary cavity 202, and the liquid storage tank 20 has a 7-shaped structure.

Specifically, the volume of the primary cavity 202 is smaller than the volume of the secondary cavity 203 by not using a height.

In a specific embodiment not shown in the figure, the primary cavity 202 and the secondary cavity 203 have the same shape, the liquid storage tank 20 is an overall rectangular structure, the bottom of the primary cavity 202 is higher than the bottom of the secondary cavity 203, and the volume of the primary cavity 202 is controlled to be smaller than the volume of the secondary cavity 203 by the difference in bottom surface height.

In this embodiment, the primary cavity 202 and the secondary cavity 203 are arranged in a horizontal direction.

As shown in Figures 10 to 15, the liquid storage tank 20 includes a box body 210, a cover plate 220 and a partition plate 230. The box body 210 has an outlet, and the cover plate 220 is detachably installed on the top of the box body 210. The box body 210 and the cover plate 220 cooperate to form a cavity therebetween. The inlet 201 is arranged on the box body 210 or the cover plate 220, and the partition plate 230 is arranged inside the cavity. The partition plate 230 divides the cavity into a primary cavity 202 and a secondary cavity 203.

The inlet 201 may be arranged on the cover plate 220 or the box body 210 , and the specific setting is based on whether the condensed water can enter the interior of the cavity through the inlet 201 under the conveying action of the conveying pipeline 70 .

Specifically, the partition 230 divides the cavity into a primary cavity 202 and a secondary cavity 203, thereby ensuring that the condensed water first enters the interior of the primary cavity 202, and controls whether the condensed water is supplied to the evaporator 40 from the first outlet 204 of the primary cavity 202 as needed, to avoid the condensed water directly entering the interior of the secondary cavity 203.

In this embodiment, the partition 230 is vertically arranged in the cavity, and an overflow port 231 is arranged on the top of the partition 230. The primary cavity 202 and the secondary cavity 203 are connected through the overflow port 231. The overflow port 231 is arranged on the top of the partition 230 to ensure that the outlet is located below the overflow port 231. Of course, the overflow port 231 can also be arranged at other positions of the partition 230. The specific position of the overflow port 231 is based on being higher than the outlet.

In this embodiment, the overflow port 231 is not limited to be provided to enable the condensed water inside the primary cavity 202 to flow to the secondary cavity 203. An overflow gap may be formed between the top of the partition 230 and the cover plate 220 to allow liquid to flow through the overflow gap.

It should be noted that the above two methods can be set separately or simultaneously.

As shown in Figures 10 to 15, in order to avoid noise and splashing when the condensed water enters the liquid storage tank 20, the heat exchange device also includes a slow flow component 90, and the inlet 201 is connected to the primary cavity 202 through the slow flow component 90. The slow flow component 90 is used to guide and slow the flow of the condensed water entering from the inlet 201.

Specifically, the slow flow assembly 90 includes a water receiving groove 901, which is formed on the cover plate 220 or the box body 210, and has a water outlet 9011, which is connected to the primary cavity 202. After the condensed water enters from the inlet 201, the condensed water flows along the inner wall of the water receiving groove 901 and flows out from the water outlet 9011. Due to the guiding effect of the water receiving groove 901, the liquid is guided to enter the interior of the primary cavity 202.

In this embodiment, when the water receiving groove 901 is provided as a whole with the cover plate 220 , the water receiving groove 901 is formed by at least a portion of the cover plate 220 being recessed into the primary cavity 202 , and the notch of the water receiving groove 901 serves as the inlet 201 .

In this embodiment, the bottom surface of the water receiving groove 901 is inclined relative to the horizontal plane and has an inclination, the inclination S is 5°-8°, and the bottom surface of the water receiving groove 901 extends downwardly along a direction close to the water outlet 9011. The inclined bottom surface has the effect of not easily generating water accumulation, so that the condensed water flows smoothly into the primary cavity 202.

In this embodiment, the inclination can be 5°, 6°, 7°, or 8°. If the inclination angle is too small, it is not conducive to the flow of condensed water, and if the inclination angle is too large, the buffering effect is affected.

As shown in Figures 10 to 15, the slow flow component 90 also includes a water retaining rib 902, which is arranged inside the primary cavity 202. The water retaining rib 902 is connected to the cover plate 220 or the box body 210. At least a portion of the water retaining rib 902 is opposite to the water outlet 9011 and is spaced apart, and a flow gap is formed between the water retaining rib 902 and the water outlet 9011, so that the condensed water flowing out of the water outlet 9011 flows into the primary cavity 202 along the flow gap and the water retaining rib 902.

Specifically, the condensed water flowing out of the water outlet 9011 flows into the primary cavity 202 along the flow gap and the water retaining rib 902. Under the guidance of the water retaining rib 902, the condensed water flows along the water retaining rib 902 to the primary cavity 202, so as to achieve the effect of not generating water flow sound or dripping sound.

In this embodiment, the water retaining rib 902 has a plate-like portion and a raised portion arranged in a T-shape, the plate-like portion is spaced apart from the water outlet 9011 , and the raised portion is disposed toward one end of the inlet 201 .

In this embodiment, the protrusion is arranged opposite to the water outlet 9011 .

In this embodiment, at least one end of the plate-like portion is spaced apart from the side of the primary cavity 202 to form a flow channel 903 for condensed water to flow, so that the condensed water, after the buffering effect of the water retaining rib 902, enters the first outlet 204 area of the primary cavity 202 through the flow channel 903.
