Detailed Implementation

[0030] See also Figures 1 to 7 As shown, according to an embodiment of the present invention, a vehicle heat exchanger is provided, comprising: a plurality of interconnected first pipes 4, one end of each first pipe 4 being a first opening 1 and the other end being a second opening 3. When the vehicle is running, the heat exchange medium in the first pipe 4 can flow from the second opening 3 to the first opening 1, and air can flow from the first opening 1 to the second opening 3, so that the heat exchange medium can exchange heat with the air through the first pipe 4. See also [link to technical solution]. Figure 1 As shown, the working fluid in the first pipe 4 flows from the second opening 3 to the first opening 1, while air flows from the first opening 1 to the second opening 3. This fully utilizes the wind energy advantage during vehicle operation, allowing the wind energy during vehicle operation to exchange heat with the working fluid in the first pipe 4 and the air, thus achieving the purpose of heat exchange. This adopts natural convection, resulting in significantly lower noise compared to the forced convection method in traditional heat pump air conditioners. During air conditioning system operation, the noise is mainly generated by the compressor and fan; the overall system noise is reduced by more than 10 dB compared to traditional heat pump air conditioners, resulting in significant energy savings of approximately 7%. Traditional heat pump air conditioners have a higher probability of outdoor fan failure; this invention uses a natural convection system that is relatively stable and reliable. It does not require external forced convection control, making the entire system control, maintenance, and management more convenient. Of course, this invention is a vehicle heat exchanger; when the vehicle is stationary, the heat exchanger can also exchange heat with relatively still air, but the heat exchange capacity is relatively small compared to the operating state, and the cooling or heating capacity is also smaller.

[0031] In some embodiments, multiple branch pipes 2 are spaced apart along the axial direction of the first pipe 4, and in the vertical direction, the height of the second opening 3 is higher than that of the first opening 1, so that the heat exchange medium in the first pipe 4 flows from the second opening 3 to the first opening 1. See also [link to technical solution]. Figure 2As shown, a plurality of branch pipes 2 are arranged on the first pipeline 4 in the axial direction of the first pipeline 4, which increases the heat exchange area of the heat exchange medium and the air, and improves the heat exchange effect of the heat exchanger. The height of the second opening 3 is higher than that of the first opening 1, that is, the low side of the heat exchanger is in the direction of the vehicle head, and the high side is in the direction of the vehicle tail, so that the heat exchange medium flows from the second opening 3 to the first opening 1 under the action of gravity, thereby saving energy consumption.

[0032] In some embodiments, a plurality of branch pipes 2 are arranged on the first pipeline 4 in the circumferential direction of the first pipeline 4, and any two adjacent first pipelines 4 are connected through any branch pipe 2, so that the heat exchange medium in the first pipeline 4 flows in a plurality of first pipelines 4. In this technical solution, a plurality of branch pipes 2 are arranged on the first pipeline 4 in the circumferential direction of the first pipeline 4, which further increases the number of branch pipes 2, improves the contact area of the heat exchange medium and the air, and any two adjacent first pipelines 4 are connected through any branch pipe 2, so that the heat exchange medium in the first pipeline 4 flows in a plurality of first pipelines 4, which ensures the flow of the heat exchange medium between a plurality of first pipelines 4 and increases the flow area of the heat exchange medium.

[0033] In some embodiments, the vehicle heat exchanger further comprises a plurality of housings 6, and each of the plurality of housings 6 corresponds to one of the plurality of first pipelines 4. The first pipeline 4 and the branch pipe 2 are located in the housing 6, and the branch pipe 2 is connected to the housing 6. In this technical solution, the first pipeline 4 and the branch pipe 2 are located in the housing 6, so that the housing 6 wraps the first pipeline 4 and the branch pipe 2. The housing 6 can protect the first pipeline 4 and the branch pipe 2, and can maximize the effective heat exchange area. Each first pipeline 4 does not interfere with each other, and the reheat is minimized.

[0034] In some embodiments, the cross section of the housing 6 is rectangular, and at least eight branch pipes 2 are arranged on the first pipeline 4 in the circumferential direction of the first pipeline 4. Taking the cross section of the housing 6 as a projection plane, one end of at least the eight branch pipes 2 is connected to the first pipeline 4, and the other end is connected to the corner or side of the housing 6, respectively. In this technical solution, by taking the cross section of the housing 6 as a projection plane, one end of at least the eight branch pipes 2 is connected to the first pipeline 4, and the other end is connected to the corner or side of the housing 6, respectively, so that the connection between the first pipeline 4 and the housing 6 is more stable, and the heat exchanger can run stably when the housing 6 is installed on the vehicle. See Figure 5As shown, when two adjacent first pipes 4 are connected through any branch pipe 2, the branch pipes 2 in the two adjacent first pipes 4 are connected after penetrating the shell 6. Along the circumference of the first pipe 4, at least eight branch pipes 2 are uniformly arranged on the first pipe 4. Of course, the shell 6 can be provided with openings at both ends, and a part of air exchanges heat with the heat exchange medium through the shell 6, and another part enters the shell 6 to exchange heat directly with the branch pipes 2 and the first pipe 4.

[0035] In some embodiments, referring to Figure 3 As shown, the vehicle heat exchanger further comprises a second pipe 5, and a plurality of first pipes 4 are connected to the second pipe 5. The vehicle heat exchanger is connected to the vehicle air conditioning system through the second pipe 5, so that the heat exchange medium in the vehicle air conditioning system is transported into the first pipe 4 through the second pipe 5. In this technical solution, the vehicle heat exchanger is connected to the vehicle air conditioning system through the second pipe 5, and the second pipe 5 serves as the main pipe of the vehicle heat exchanger. After the heat exchange medium in the air conditioning system flows into the second pipe 5, it is transported into the first pipe 4 through the second pipe 5, achieving the effect of flow splitting, thereby improving the heat exchange efficiency.

[0036] In some embodiments, the vehicle heat exchanger further comprises a first fixing member 8, one side of the first fixing member 8 is provided with the first pipe 4, and the other side is mounted on the vehicle. When the vehicle is running, the flow direction of the heat exchange medium in the first pipe 4 is opposite to the flow direction of the air. In this technical solution, the first pipe 4 is mounted on the vehicle through the first fixing member 8, and when the vehicle is running, the flow direction of the heat exchange medium in the first pipe 4 is opposite to the flow direction of the air. The wind energy during vehicle driving is fully utilized to make the heat exchanger fully exchange heat with the wind, and at this time, the vehicle cooling or heating requirements can be met.

[0037] In some embodiments, referring to Figure 4As shown, the first fixing member 8 is provided with a plurality of second fixing members 7 and a plurality of third fixing members 10, the second fixing members 7 are close to the end of the first fixing member 8 relative to the third fixing members 10, and in the vertical direction, the height of the third fixing member 10 is higher than that of the second fixing member 7, and the second fixing member 7 and the third fixing member 10 are connected to the first pipeline 4. In this technical solution, in the vertical direction, the height of the third fixing member 10 is higher than that of the second fixing member 7, and the first pipeline 4 is installed on the second fixing member 7 and the third fixing member 10, so that the heat exchange medium flows from the second opening 3 to the first opening 1 under the action of gravity, saving energy consumption. When installing, place the vehicle heat exchanger of the present application on the top of the vehicle, fix the heat exchanger with the first fixing member 8, the second fixing member 7 and the third fixing member 10, and then fix it with the connecting member 9. The contact part of the first fixing member 8, the second fixing member 7 and the third fixing member 10 with the heat exchanger can be firmly welded,

[0038] The vehicle heat exchanger of the present application does not need to set a forced convection device on the outside of the heat pump air conditioning system, and other parts can be consistent with the traditional heat pump air conditioning system. On the basis of meeting the requirements of refrigeration and heating, low noise, low energy consumption, operation control and maintenance management are realized.

[0039] When the vehicle heat exchanger of the present application is applied to a vehicle, the heat exchanger inlet pipe is in the tail direction, and the outlet pipe is in the head direction, that is, the low side of the heat exchanger is in the head direction, and the high side is in the tail direction. During vehicle operation, air enters the heat exchanger shell and exchanges heat with the working medium in the opposite direction, which is opposite to the running direction of the heat exchange working medium, forms reverse heat exchange and improves the heat exchange efficiency. The heat exchanger working medium inlet is in the high side, and the outlet is in the low side. The gravity can also be used to strengthen the heat exchange. In terms of installation, the heat exchanger is placed on the top of the vehicle, the heat exchanger is fixed with the fixing frame, and then it is fixed with the fixing bolt. The contact part of the fixing support and the heat exchanger can be firmly welded.

[0040] The heat exchanger of the present application is applied to a vehicle, mainly in two modes. When the vehicle is running, the heat exchanger of the present application fully exchanges heat with the wind, and at this time the vehicle refrigeration or heating demand can be met; when the vehicle is in a static state, the heat exchanger of the present application can also exchange heat with the relatively static air. Compared with the running state, the heat exchange amount is relatively small, and the refrigeration or heating capacity is also small.

[0041] In terms of the heat exchanger body, each heat exchange unit has a main pipe and multiple branch pipes, and a shell, each heat exchanger can be assembled by multiple heat exchanger units, and the assembly method can use welding, for example, the high side is the working medium inlet, and the low side is the working medium outlet; on the pipeline, every certain distance, eight branch pipes are branched off in different directions, the included angles between the eight branch pipes are equal, and the related dimensions can be calculated according to the actual application of the heat exchanger. Each heat exchanger unit is provided with a shell wrapped outside the heat exchanger pipeline and branch pipes, and can be welded and fixed with the pipeline, and the shell can play a protective role. Each heat exchanger unit of the heat exchanger is not only provided with a pipeline and branch pipes, but also provided with a shell, so that the effective heat exchange area can be maximized, and each heat exchange unit does not interfere with each other, and the reheat is maximally reduced.

[0042] The heat exchanger of the present application can be used not only in vehicles, but also in ships and other occasions, and can be used not only outdoors, but also indoors, and can be used in cooperation with forced convection equipment. The heat exchange medium of the vehicle heat exchanger of the present application can be refrigerant, water or other heat exchange medium. The vehicle heat exchanger of the present application can also be assembled in other forms according to specific conditions.

[0043] The present application also provides an air conditioner comprising the vehicle heat exchanger.

[0044] In some embodiments, the air conditioner comprises a four-way valve 11, a first heat exchanger 14, an expansion valve 15, a second heat exchanger 16 and a compressor 17, the compressor 17, the four-way valve 11, the first heat exchanger 14, the expansion valve 15 and the second heat exchanger 16 are connected to form a circulation loop; the first heat exchanger 14 is communicated with the first opening 1, the second opening 3 is communicated with a pump body 12, the pump body 12 is communicated with a liquid storage member 13, one end of the liquid storage member 13 is communicated with the pump body 12, and the other end is communicated with the first heat exchanger 14, the first heat exchanger 14, the vehicle heat exchanger, the pump body 12 and the liquid storage member 13 are connected to form a heat exchange circulation loop. In this technical solution, referring to Figure 6 when the vehicle needs cooling in summer, the refrigerant circulation flow path system is: compressor 17→four-way valve 18→first heat exchanger 14→expansion valve 15→second heat exchanger 16→four-way valve 11→compressor 17, forming a complete refrigerant circulation system. The solution circulation flow path system is: pump body 12→liquid storage member 13→first heat exchanger 14→vehicle heat exchanger→pump body 12, forming a complete solution circulation system; referring to Figure 7 when the vehicle needs heating in winter, the refrigerant circulation flow path system is: compressor 17→four-way valve 11→second heat exchanger 16→expansion valve 15→first heat exchanger 14→four-way valve 11→compressor 17, forming a complete refrigerant circulation system. The solution circulation flow path system is: pump body 12→liquid storage member 13→first heat exchanger 14→vehicle heat exchanger→pump body 12, forming a complete solution circulation system.

[0045] The application further provides a vehicle comprising the air conditioner.

[0046] In some embodiments, the vehicle comprises a covering device arranged on the vehicle heat exchanger, the covering device is opened to cover the vehicle heat exchanger when the air conditioner is cooling, and the covering device is closed when the air conditioner is heating. In this technical solution, when the vehicle heat exchanger is running in summer, the vehicle heat exchanger is exposed to the sun due to the solar radiation of the vehicle roof, which is not conducive to the effect of the refrigerant system. The vehicle heat exchanger is covered with a roll-up curtain made of anti-exposure material to prevent the temperature of the solution in the vehicle heat exchanger from being too high, which does not affect the heat exchange of the vehicle heat exchanger when the vehicle is running. At the same time, the temperature is low at night in summer and there is no solar radiation, so the water pump can be started to pre-cool the vehicle heat exchanger. During the day, the refrigerant system can use the cold energy in the storage liquid tank to exchange heat with the refrigerant system through the first heat exchanger, thereby improving the energy-saving effect of the whole machine. When the vehicle heat exchanger is running in winter, the roll-up curtain made of anti-exposure material arranged on the vehicle roof is closed, and the vehicle heat exchanger is heated by solar radiation when it is running. At the same time, the vehicle heat exchanger can be heated by air convection when the vehicle is running. The heat generated by solar radiation when the vehicle is stopped can be brought into the storage liquid tank by the water pump for energy storage, which is used when the vehicle is running, thereby improving the energy-saving effect of the whole machine. The natural wind in summer and solar energy in winter can be effectively utilized, and the energy-saving and environmental protection effects can be achieved. The solution in the vehicle heat exchanger can be refrigerant, brine, 50% ethylene glycol, etc.
