[0050] Various exemplary embodiments of the present application will now be described in detail with reference to the accompanying drawings. It should be noted that unless otherwise specifically stated, the relative arrangement of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present application.

[0051] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the present application, its application, or uses.

[0052] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0053] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0054] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0055] Reference Figure 1-Figure 9 As shown, according to one embodiment of the present application, a radiation heat exchanger 1 is provided. The radiation heat exchanger 1 comprises a heat exchange component 11, an inlet component 12, an outlet component 13 and a heat-conducting shell 15, wherein the heat exchange component 11 has a first heat exchange side;

[0056] The inlet component 12 is connected to the inlet end of the heat exchange component 11, and the inlet component 12 is used to supply coolant to enter the heat exchange component 11; the outlet component 13 is connected to the outlet end of the heat exchange component 11, and the outlet component 13 is used to receive the coolant flowing out of the heat exchange component 11; the heat conductive shell 15 is connected to the first heat exchange side of the heat exchange component 11, and heat is exchanged between the heat exchange component 11 and the outside of the first heat exchange side through the heat conductive shell 15.

[0057] In the radiation heat exchanger 1 provided in the embodiment of the present application, the coolant flows into the heat exchange component 11 from the inlet component 12, and the heat exchange process of the coolant flowing in the heat exchange component 11 can cool down the heat exchange component 11; after completing the heat exchange process, the coolant flows from the heat exchange component 11 into the outlet component 13, and then flows out of the radiation heat exchanger 1 from the outlet component 13.

[0058] The heat exchange component 11 has a first heat exchange side, which can be, for example, a side with a larger area in the heat exchange component 11. In the radiation heat exchanger 1 provided in the embodiment of the present application, since the first heat exchange side of the heat exchange component 11 is connected to the heat conductive shell 15, the heat conductive shell 15 is made of a material with high thermal conductivity, such as a metal material, and has good thermal conductivity. Therefore, the coolant transfers the cold to the heat exchange component 11, and the heat exchange component 11 then transfers the cold to the outside of the first heat exchange side through the heat conductive shell 15, that is, radiates cooling to the outside of the first heat exchange side. In actual applications, when the radiation heat exchanger 1 is installed, the heat conductive shell 15 corresponds to the passenger compartment side.

[0059] In summary, the radiant heat exchanger provided in the embodiment of the present application does not need to adopt the method of direct blowing of cold air for cooling; it transfers the cold energy of the coolant to the heat exchange component 11 and then to the heat-conducting shell 15, so as to achieve the purpose of radiant cooling for the outside of the heat-conducting shell 15, thereby achieving a better cooling effect and improving the experience of the passengers in the car.

[0060] Reference Figure 1 to Figure 4 As shown, in one embodiment, the heat exchange component 11 has a second heat exchange side, and the second heat exchange side is arranged opposite to the first heat exchange side;

[0061] The radiation heat exchanger further includes a heat insulation component 14, which is connected to the second heat exchange side of the heat exchange component 11, and is used to isolate the heat exchange between the heat exchange component 11 and the outside of the second heat exchange side.

[0062] In this specific example, the heat exchange component 11 has a second heat exchange side surface arranged opposite to the first heat exchange side surface, and the second heat exchange side surface can be, for example, a side surface with a larger area in the heat exchange component 11. In the radiation heat exchanger 1 provided in the embodiment of the present application, since the second heat exchange side surface of the heat exchange component 11 is connected to the heat insulation component 14, the heat insulation component 14 has the function of isolating heat exchange, so it can avoid heat exchange between the heat exchange component 11 and the outside of the second heat exchange side surface. In actual application, when the radiation heat exchanger 1 is installed, the heat insulation component 14 corresponds to the outside of the vehicle, and the heat conduction shell 15 corresponds to the passenger compartment side. By setting the heat insulation component 14, the radiation heat exchanger can achieve radiation cooling only to the outside of the heat conduction shell 15, and isolate the heat exchange with the outside of the heat insulation component 14, so that the radiation heat exchanger can achieve better radiation cooling effect.

[0063] Reference Figure 1 to Figure 4 As shown, in one embodiment, the heat exchange assembly 11 includes a heat exchange tube 111 and a heat exchange fin 112, the heat exchange tube 111 is passed through the heat exchange fin 112, and the heat exchange tube 111 and the heat exchange fin 112 are cross-connected at a predetermined angle;

[0064] One side of the heat exchange fin 112 is closely connected to the heat insulation assembly 14 , and the other side of the heat exchange fin 112 is closely connected to the heat conduction housing 15 .

[0065] In this specific example, the coolant flowing through the heat exchange tube 111 transfers the cold energy to the heat exchange tube 111, and the heat exchange tube 111 then transfers the cold energy to the heat exchange fin 112 connected thereto; the heat exchange fin 112 then radiates the cold energy to the outside of the heat conductive shell 15 through the heat conductive shell 15; at the same time, due to the presence of the heat insulation component 14, the heat exchange fin 112 basically does not exchange heat with the outside of the heat insulation component 14.

[0066] Reference Figure 1 to Figure 3 As shown, in one embodiment, a plurality of the heat exchange tubes 111 are provided, and the plurality of heat exchange tubes 111 are arranged in parallel and at intervals.

[0067] In this specific example, a plurality of heat exchange tubes 111 are provided, and coolant can flow through each heat exchange tube 111, thereby improving the heat exchange efficiency of the radiation heat exchanger 1. In addition, since the plurality of heat exchange tubes 111 are arranged in parallel and at intervals, rather than being arranged as conventional serpentine heat exchange tubes, each heat exchange tube 111 constitutes an independent one-way flow channel, and the resistance to the flow of coolant in the heat exchange tube 111 is small, and the required driving power is low.

[0068] In one embodiment, the inner diameter of the heat exchange tube 111 is 3-5 mm.

[0069] In this specific example, the size of the heat exchange tube 111 is of a small diameter rather than a capillary diameter, which can also ensure that the resistance of the coolant flowing in the heat exchange tube 111 is small and the required driving power is low.

[0070] Reference Figure 2 , Figure 4 As shown, in one embodiment, a plurality of heat exchange fins 112 are provided, and the plurality of heat exchange fins 112 are arranged in parallel and at intervals.

[0071] In this specific example, a plurality of heat exchange fins 112 arranged in parallel and at intervals can improve the efficiency of transferring cold to the heat transfer housing 15. Each heat exchange fin 112 is provided with a plurality of through holes for the heat exchange tubes 111 to pass through, that is, any heat exchange tube 111 passes through all heat exchange fins 112. The heat exchange tubes 111 and the heat exchange fins 112 can be tightly connected by a tube expansion process.

[0072] Optionally, the predetermined angle at which the heat exchange tube 111 and the heat exchange fin 112 are cross-connected is 90°, that is, the extension direction of the heat exchange tube 111 and the extension direction of the heat exchange fin 112 are perpendicular to each other.

[0073] In one embodiment, the thickness of the heat exchange fins 112 is 0.2 mm to 1 mm; and the distance between two adjacent heat exchange fins 112 is 1 to 3 mm.

[0074] In this specific example, the heat exchange fins 112 are made of a material with high thermal conductivity and high strength; their thickness is 0.2 mm to 1 mm, and the distance between two adjacent heat exchange fins 112 is 1 to 3 mm, thereby ensuring that there is sufficient contact area between the heat exchange fins 112 and the heat conduction shell 15 to efficiently transfer cold to the heat conduction shell 15.

[0075] In addition, one heat exchange fin 112 closest to the inlet assembly 12 and one heat exchange fin 112 closest to the outlet assembly 13 have a greater thickness than other heat exchange fins to ensure structural strength.

[0076] Reference Figure 4 As shown, in one embodiment, the heat exchange component 11 further includes a phase change material 113 , and the phase change material 113 is filled between two adjacent heat exchange fins 112 ; the phase change material 113 is in contact with the heat conductive housing 15 .

[0077] In this specific example, the phase change material 113 can expand the equivalent specific heat capacity of the radiation heat exchanger 1 and enhance the cold storage capacity of the radiation heat exchanger 1 .

[0078] Therefore, the radiation heat exchanger 1 can work in the following working modes:

[0079] a. Direct cooling mode:

[0080] When the coolant flows through the heat exchange tube 111, the heat exchange fins 112 and the heat-conducting housing 15 are rapidly cooled, thereby absorbing the heat in the vehicle; in this process, part of the phase change material 113 is also cooled and solidified;

[0081] b. Energy storage mode:

[0082] When there is no cooling demand in the vehicle, but the vehicle is connected to low-cost electricity (such as night-time off-peak electricity), the cold storage mode is turned on. At this time, the coolant also flows through the heat exchange tube 111, and the phase change material 113 filled between the heat exchange fins 112 is cooled and solidified; when the phase change material 113 is completely solidified, the air conditioning system stops cooling;

[0083] c. Energy storage refrigeration mode:

[0084] During the day, as the temperature in the passenger compartment gradually rises, the phase change material 113 can continuously absorb the heat in the vehicle to maintain a constant temperature; at this time, the heat load in the vehicle can be reduced without consuming electrical energy, thereby achieving the purpose of saving energy. During daytime driving, if the phase change material 113 has not yet completely melted, the low-temperature phase change material 113 can still cool the passenger compartment, further saving air conditioning power consumption; when the phase change material 113 is completely melted, the air conditioning system can be turned on, and the coolant flows through the heat exchange tube 111 again to cool the passenger compartment.

[0085] In a specific example, the radiation heat exchanger 1 is a plate structure, which also has a third heat exchange side and a fourth heat exchange side that are arranged opposite to each other, and the area of ​​the third heat exchange side and the fourth heat exchange side is much smaller than the area of ​​the second heat exchange side and the first heat exchange side. Sealing plates 16 are respectively arranged on the third heat exchange side and the fourth heat exchange side, and the sealing plates 16 are made of a heat-insulating material with a certain structural strength. One of the sealing plates 16 is connected to a filling pipe 17, which is used to inject the phase change material 113 and facilitate the maintenance and replacement of the phase change material 113.

[0086] Reference Figure 5 As shown, in one embodiment, the inlet assembly 12 includes an inlet pipe 121 and a liquid outlet pipe 122, a liquid outlet is provided on a side wall of the inlet pipe 121, and the number of the liquid outlet, the liquid outlet pipe 122 and the heat exchange tube 111 is the same and is arranged one by one;

[0087] One end of the liquid outlet pipe 122 is connected to the liquid outlet, and the other end of the liquid outlet pipe 122 is connected to the first end of the heat exchange tube 111 .

[0088] In this specific example, the inlet pipe 121 with multiple liquid outlets on the side wall is in a flute-shaped structure, and the coolant flowing into the inlet pipe 121 is distributed to the heat exchange tube 111 through the liquid outlet and the liquid outlet pipe 122. Each heat exchange tube 111 corresponds to a liquid outlet pipe 122 and a liquid outlet, ensuring that the coolant can be evenly distributed to each heat exchange tube 111.

[0089] Reference Figure 5 As shown, in one embodiment, the inlet pipe 121 includes a first pipe section 1211 and a second pipe section 1212 , the diameter of the first pipe section 1211 is smaller than the diameter of the second pipe section 1212 ; the liquid outlet is opened on the side wall of the second pipe section 1212 .

[0090] In this specific example, the coolant first flows into the first pipe section 1211 with a smaller diameter, at which time the flow rate of the coolant is faster; then the coolant enters the second pipe section 1212 with a larger diameter, and the flow rate of the coolant decreases, thereby further ensuring that the coolant can be more evenly distributed to each heat exchange tube 111.

[0091] Optionally, the diameter of the second pipe section 1212 is 2 to 2.5 times the diameter of the liquid outlet pipe 122 ; the length of each liquid outlet pipe 122 extending into the second pipe section 1212 is 5 to 10 mm; the diameter of the first pipe section 1211 is 1.5 times the diameter of the liquid outlet pipe 122 .

[0092] Reference Figure 6 As shown, in one embodiment, the outlet assembly 13 includes an outlet pipe 131 and a liquid inlet pipe 132, and a liquid inlet port is opened on the side wall of the outlet pipe 131, and the number of the liquid inlet ports, the liquid inlet pipe 132 and the heat exchange tube 111 is the same and is arranged one by one; one end of the liquid inlet pipe 132 is connected to the liquid inlet port, and the other end of the liquid inlet pipe 132 is connected to the second end of the heat exchange tube 111.

[0093] Reference Figure 6 As shown, in one embodiment, the outlet pipe 131 includes a third pipe segment 1311 and a fourth pipe segment 1312 , the diameter of the third pipe segment 1311 is smaller than the diameter of the fourth pipe segment 1312 ; the liquid inlet is opened on the side wall of the fourth pipe segment 1312 .

[0094] The structure of the outlet assembly 13 is completely the same as that of the inlet assembly 12, and will not be described in detail here. Among them, the fourth pipe section 1312 can play the role of converging and buffering, and reducing the flow resistance of the coolant.

[0095] Reference Figure 3 , Figure 4 As shown, in one embodiment, the heat insulation component 14 includes a heat insulation layer 141 and a reflective layer 142 , and the reflective layer 142 is laminated and connected to a side of the heat insulation layer 141 away from the heat exchange component 11 .

[0096] In this specific example, the heat insulating layer 141 serves to isolate the conduction heat and the convection heat, while the reflective layer 142 serves to isolate the radiant heat. That is, the heat insulating component 14 can isolate both the heat conducted from the outside and the heat radiated from the outside. The material of the heat insulating layer 141 can be, for example, foam, and the reflective layer 142 can be, for example, a reflector.

[0097] The coolant may be composed of, for example, deionized water or a water-ethylene glycol mixture; it has low viscosity, high specific heat capacity, and a melting point below -10°C.

[0098] Reference Figure 7 As shown, in the radiation heat exchanger 1, the complete flow process of the coolant is divided into: a liquid inlet process P1, a liquid separation process P2, a heat exchange process P3, a liquid collection process P4 and a liquid outlet process P5.

[0099] According to another embodiment of the present application, an air conditioning system is provided, wherein the air conditioning system includes the radiation heat exchanger 1 as described above.

[0100] The air conditioning system provided in the embodiment of the present application adopts the above-mentioned radiation heat exchanger 1, which does not include a refrigerator that directly blows cold air, and has a better cooling effect.

[0101] Reference Figure 8 As shown, in one embodiment, the air conditioning system further includes a dehumidification evaporator 2, and the air conditioning system has two cooling circuits, the radiation heat exchanger 1 is arranged in one of the cooling circuits, and the dehumidification evaporator 2 is arranged in the other cooling circuit.

[0102] In this specific example, the air conditioning system sets the wet load cold source and the heat load cold source separately; wherein the dehumidification evaporator 2 is the wet load cold source, and the radiation heat exchanger 1 is the heat load cold source. As a heat load cold source, the surface temperature of the radiation heat exchanger 1 does not need to be as low as the dew point temperature, that is, it is not necessary to use low-temperature air to remove the heat load of the passenger compartment. This can reduce the heat transfer loss caused by the large temperature difference, improve the efficiency of the air conditioning system, and reduce the energy consumption of air conditioning.

[0103] The detailed working process of the air conditioning system provided in the embodiment of the present application is as follows:

[0104] First, the compressor 3 is started to drive the refrigerant circulation. The refrigerant squeezed out by the compressor 3 enters two cooling circuits after being cooled by the external condenser 4. One of the cooling circuits is provided with a partition-type heat exchanger 20, and its flow rate and throttling temperature are controlled by the opening of the first branch expansion valve 51; the other cooling circuit is provided with a dehumidification evaporator 2, and its flow rate and throttling temperature are controlled by the opening of the second branch expansion valve 52. In the partition-type heat exchanger 20, the refrigerant and the coolant exchange heat, and the cooled coolant is pumped into the radiation heat exchanger 1 by the driving pump 6.

[0105] The temperature and humidity sensor 7 is used to detect the temperature and humidity of the fresh air F in front of the blower 8, so as to control the opening of the second branch expansion valve 52 and further control the evaporation temperature of the dehumidification evaporator 2. When the passengers in the vehicle set the temperature of the air conditioning system, the vehicle controller calculates the predetermined absolute humidity value of the air in the vehicle, and the absolute humidity of the fresh air F passing through the dehumidification evaporator 2 must reach this preset value. The heat load in the passenger compartment caused by heat leakage from the enclosure structure and external radiation is cooled by the radiation heat exchanger 1.

[0106] In this specific example, three radiation heat exchangers 1 are provided; the branches where the three radiation heat exchangers 1 are located are respectively regulated by the first solenoid valve 91, the second solenoid valve 92 and the third solenoid valve 93 to adjust the opening and closing and the circulation flow of the coolant. The coolant after absorbing heat in each branch is collected and returned to the partition-type heat exchanger 20 to complete the circulation; the function of the one-way valve 90 is to prevent the coolant in each branch from flowing back.

[0107] The fresh air F refers to the incoming air passing through the blower 8 and the dehumidification evaporator 2; when the external circulation mode is turned on, the fresh air F is the fresh air entering from outside the vehicle; when the internal circulation mode is turned on, the fresh air F is the return air inside the vehicle.

[0108] In this air-conditioning system, the air entering the passenger compartment has been dehumidified by the dehumidification evaporator 2 in advance, and the surface of the radiation heat exchanger 1 does not need to be lower than the dew point temperature; therefore, the surface of the radiation heat exchanger 1 does not have common problems such as condensation and drainage, and the air-conditioning system operates more stably.

[0109] Reference Figure 8 As shown, in one embodiment, the number of the radiation heat exchangers 1 is at least two, wherein one of the radiation heat exchangers 1 is arranged on the roof of the vehicle to which the air-conditioning system is applied, and the other radiation heat exchanger 1 is arranged on the bottom of the vehicle to which the air-conditioning system is applied.

[0110] In this specific example, a plurality of radiation heat exchangers 1 can be arranged according to specific usage requirements, so that the working efficiency of the air-conditioning system is higher.

[0111] Reference Fig. 9 As shown, for example, a total of four radiation heat exchangers 1 can be arranged; namely, a front door radiation heat exchanger 101 arranged on the front door panel, a rear door radiation heat exchanger 102 arranged on the rear door panel, an upper radiation heat exchanger 103 arranged on the roof, and a lower radiation heat exchanger 104 arranged at the bottom of the passenger compartment. The inlet G, outlet E, and drive pump 6 of the coolant are all arranged in the front compartment.
