Description

Technical Field

[0001] The present application relates to the technical field of automobile air-conditioning accessories, and in particular to an automobile air-conditioning dual-purpose cooling and heating integrated core, an automobile air-conditioning and a vehicle. Background Art

[0002] At present, the automotive air-conditioning industry is implementing control, reduction and even elimination of HFCs refrigerants, and developing green refrigerants. Refrigerant substitution has become the mission of the times. Therefore, based on the industry's demand for environmentally friendly refrigerants, R290 (propane) refrigerant has been highly praised by the industry.

[0003] like Figure 1 As shown, a secondary heat exchange heat pump system is developed based on R290 to ensure that the R290 refrigerant does not pass through the passenger compartment to ensure the safety of personnel. As a result, the existing air-conditioning box cannot meet the requirements, and the evaporation core a of the existing solution needs to be cancelled and replaced with a cooling core b.

[0004] However, since the cooling core b and the heating core c in the R290 secondary heat exchange system air-conditioning box are currently designed independently, and the cooling core b needs to increase the heat exchange capacity, its size is larger than that of the conventional system air-conditioning box. This requires more space for the air-conditioning box, and this independent structure requires the manufacturer to process the cooling core b and the heating core c at the same time, which not only increases the labor capital, but also increases the input of raw materials.

[0005] Therefore, it is urgent to provide an integrated core body for cooling and heating of an automobile air conditioner, an automobile air conditioner and a vehicle to solve the above-mentioned technical problems. Summary of the invention

[0006] In view of the deficiencies in the prior art, the present application provides an integrated core for heating and cooling of an automobile air conditioner, an automobile air conditioner and a vehicle. By integrating the warm air core and the cooling core into one core, the space of the air conditioning box can be saved. The reduced space and lighter weight will not increase the weight of the car body too much when installed in the car, thereby reducing the energy consumption of the car and saving energy.

[0048] Example 1

[0049] This embodiment provides an integrated core body for cooling and heating of automobile air conditioner, which is described in detail below. Figure 2-Figure 4As shown, it includes: an upper header 1, a lower header 2, and a first heat exchange tube 3 and a second heat exchange tube 4 arranged between the upper header 1 and the lower header 2, and the first heat exchange tube 3 and the second heat exchange tube 4 are arranged alternately; wherein, a first heat exchange channel is formed between the upper header 1, the lower header 2 and the first heat exchange tube 3, and a first medium flows in the first heat exchange channel, and the first medium is a heat exchange or cooling medium; a second heat exchange channel is formed between the upper header 1, the lower header 2 and the second heat exchange tube 4, and a second medium flows in the second heat exchange channel, and the second medium is a heat exchange or cooling medium.

[0050] In this embodiment, a first heat exchange channel is formed between the upper manifold 1, the lower manifold 2 and the first heat exchange tube 3, and a first medium flows through the first heat exchange channel. The first medium can be a heat exchange or cooling medium. When it is set as a cooling medium such as cooling water, the first heat exchange channel is used to achieve the cooling core; a second heat exchange channel is formed between the upper manifold 1, the lower manifold 2 and the second heat exchange tube 4. A second medium flows through the second heat exchange channel. The second medium can be a heat exchange or cooling medium. When it is set as a heat exchange medium such as hot water, the second heat exchange channel is used to achieve the heating core. The function is to make the warm air core and the cooling core into an integrated core, which can save space in the air-conditioning box and is lighter in weight. When installed in a car, it will not increase the weight of the car body too much, thereby reducing the energy consumption of the car and saving energy. At the same time, compared with the traditional independent structure, the integrated core in this embodiment also reduces the production cost and the input of raw materials during processing and manufacturing, and is convenient and easy to install. In addition, the first heat exchange tube 3 and the second heat exchange tube 4 are alternately arranged between the upper collecting tube 1 and the lower collecting tube 2, so that the hot and cold mixed air is more uniform.

[0051] Please continue to refer to Figure 2-Figure 4 As shown, in the present embodiment, it should be noted that the upper collecting tube 1 and the lower collecting tube 2 are both configured as rectangles. Of course, they are not limited to rectangles, and they can also be cylindrical in other embodiments. In the present embodiment, only the rectangle is used as an example for explanation. The interior of the upper collecting tube 1 is provided with a first collecting chamber 11 and a second collecting chamber 12 of upper and lower layers, and the interior of the lower collecting tube 2 is provided with a third collecting chamber 21 and a fourth collecting chamber 22 of upper and lower layers. The first collecting chamber 11, the first heat exchange tube 3 and the third collecting chamber 21 constitute a first heat exchange channel, and the second collecting chamber 12, the second heat exchange tube 4 and the fourth collecting chamber 22 constitute a second heat exchange channel.

[0052] Specifically, the first heat exchange tube 3 and the second heat exchange tube 4 are both configured as flat tubes, which are not limited to flat tubes. In other embodiments, they can also be round tubes. In this embodiment, the flat tube is used as an example for explanation. The upper end of the first heat exchange tube 3, i.e., the first end, passes through the second liquid collecting chamber 12 and is connected to the first liquid collecting chamber 11. The lower end of the first heat exchange tube 3, i.e., the second end, is connected to the third liquid collecting chamber 21. Thus, the first liquid collecting chamber 11, the first heat exchange tube 3 and the third liquid collecting chamber 21 constitute a first heat exchange channel; the upper end of the second heat exchange tube 4, i.e., the first end, is connected to the second liquid collecting chamber 12. The lower end of the second heat exchange tube 4, i.e., the second end, passes through the third liquid collecting chamber 21 and is connected to the fourth liquid collecting chamber 22. Thus, the second liquid collecting chamber 12, the second heat exchange tube 4 and the fourth liquid collecting chamber 22 constitute a second heat exchange channel. Of course, in other implementations, the connection method of the first heat exchange tube 3 and the second heat exchange tube 4 can also be exchanged. The specific connection method is not specifically limited in this embodiment. In this embodiment, the upper collecting pipe 1 and the lower collecting pipe 2 are double-layered, and thus can be used as collecting pipes for the first heat exchange tubes 3 and the second heat exchange tubes 4 .

[0053] In this embodiment, it should be noted that the upper manifold 1 or the lower manifold 2 is connected to the first inlet pipe and the first outlet pipe, and the upper manifold 1 or the lower manifold 2 is connected to the second inlet pipe and the second outlet pipe. A first partition 13 is provided in the first liquid collecting chamber 11 or the third liquid collecting chamber 21, and the first partition 13 divides the interior of the first liquid collecting chamber 11 or the third liquid collecting chamber 21 into a first liquid inlet chamber 14 and a first liquid outlet chamber 15 for the first medium to enter and exit. In this embodiment, the first partition 13 is arranged in the first liquid collecting chamber 11 as an example for explanation. At this time, the first partition 13 divides the first liquid collecting chamber 11 into a first liquid inlet chamber 14 on the left and a first liquid outlet chamber 15 on the right. The first inlet pipe is arranged at one end of the upper collecting pipe 1 and is correspondingly connected to the first liquid inlet chamber 14. The first outlet pipe is arranged at the other end of the upper collecting pipe 1 and is correspondingly connected to the first liquid outlet chamber 15. The upper ends of all the first heat exchange tubes 3 located in the first liquid inlet chamber 14 are in a connected state, the upper ends of all the first heat exchange tubes 3 located in the first liquid outlet chamber 15 are in a connected state, and the lower ends of all the first heat exchange tubes 3 located in the third liquid collecting chamber 21 are in a connected state. Thus, the first medium enters the first liquid inlet cavity 14 through the first inlet pipe, and the first medium is distributed to a plurality of first heat exchange tubes 3 in the first liquid inlet cavity 14, and flows uniformly from the upper ends of the plurality of first heat exchange tubes 3 to the lower ends, and then all flows into the third liquid collecting cavity 21, and the first medium flows along the x direction in the third liquid collecting cavity 21, and then flows from the lower ends of the corresponding first heat exchange tubes 3 to the upper ends, and then all flows into the first liquid outlet cavity 15, and then flows out through the first outlet pipe, and then the direction of the first heat exchange channel is set in a U shape. The first partition 13 is set in the first liquid collecting cavity 11, thereby changing the flow direction of the first medium, so that the utilization efficiency of the first medium is better, the product structure is small, and it is easy to use.

[0054] A second partition 16 is provided in the second liquid collecting chamber 12 or the fourth liquid collecting chamber 22. The second partition 16 divides the interior of the second liquid collecting chamber 12 or the fourth liquid collecting chamber 22 into a second liquid inlet chamber 17 and a second liquid outlet chamber 18 for the second medium to enter and exit. In this embodiment, the second partition 16 is provided in the second liquid collecting chamber 12 as an example for explanation. At this time, the second partition 16 divides the second liquid collecting chamber 12 into a second liquid inlet chamber 17 on the left and a second liquid outlet chamber 18 on the right. The second inlet pipe is provided at one end of the upper manifold 1 and is correspondingly connected to the second liquid inlet chamber 17. The second outlet pipe is provided at the other end of the upper manifold 1 and is correspondingly connected to the second liquid outlet chamber 18. The upper ends of all the second heat exchange tubes 4 located in the second liquid inlet chamber 17 are in a connected state. The upper ends of all the second heat exchange tubes 4 located in the second liquid outlet chamber 18 are in a connected state. The lower ends of all the second heat exchange tubes 4 located in the fourth liquid collecting chamber 22 are in a connected state. Thus, the second medium enters the second liquid inlet chamber 17 through the second inlet pipe, and the second medium is distributed to a plurality of second heat exchange tubes 4 in the second liquid inlet chamber 17, and flows uniformly from the upper ends of the plurality of second heat exchange tubes 4 to the lower ends, and then all flows into the fourth liquid collecting chamber 22, in which the second medium flows along the x direction, and then flows from the lower ends of the corresponding second heat exchange tubes 4 to the upper ends, and then all flows into the second liquid outlet chamber 18, and then flows out through the second outlet pipe, and then the direction of the second heat exchange channel is set in a U shape. A second partition 16 is set in the second liquid collecting chamber 12, thereby changing the flow direction of the second medium, making the utilization efficiency of the second medium better, the product structure is small, and it is easy to use.

[0055] When working, the integrated core can realize the entry and exit of the first medium such as cooling water through the first inlet pipe and the first outlet pipe, and realize the entry and exit of the second medium such as hot water through the second inlet pipe and the second outlet pipe, thereby realizing the uniformity of the flow of both cold and hot fluids, and when the first heat exchange tube 3 and the second heat exchange tube 4 both pass through a medium such as the first medium or the second medium, they can be used in conjunction with the cooling core or the warm air core in an ordinary air-conditioning box.

[0056] In this embodiment, it should also be noted that a heat conduction structure 5 is provided between the first heat exchange tube 3 and the second heat exchange tube 4 to transfer heat by heat conduction. The heat conduction structure 5 is a fin, and the fin is a continuous structure or a discontinuous structure. Regarding the shape of the fin, a convenient arrangement can also be selected according to actual needs. Preferably, the fin is wavy or V-shaped. Between the cold side heat exchange tube 3 and the second heat exchange tube 4, the fin can be a continuous structure, that is, the fins are arranged continuously to achieve a larger heat dissipation area; it can also be a discontinuous structure, that is, the fins are spaced a certain distance apart, and key areas can be selected for enhanced heat exchange to save materials and simplify the manufacturing process while ensuring the heat dissipation effect.

[0057] Embodiment 2

[0058] Please refer to Figure 5-Figure 10 As shown, in the second embodiment, the first heat exchange tube 3 can be made into a double row or more rows, and the first heat exchange tube 3 is arranged in a plurality of rows along a direction perpendicular to the alternating arrangement of the first heat exchange tube 3 and the second heat exchange tube 4, and the first medium between the plurality of rows of the first heat exchange tube 3 is sequentially conducted. Of course, the second heat exchange tube 4 can also be made into a double row or more rows, and the second heat exchange tube 4 is arranged in a plurality of rows along a direction perpendicular to the alternating arrangement of the first heat exchange tube 3 and the second heat exchange tube 4, and the second medium between the plurality of rows of the second heat exchange tube 4 is sequentially conducted. The specific arrangement is not specifically limited in this embodiment, and this embodiment is only described by taking the double row of the first heat exchange tube 3 as an example.

[0059] In this embodiment, it should be noted that the direction in which the first heat exchange tube 3 and the second heat exchange tube 4 are alternately arranged between the upper collecting tube 1 and the lower collecting tube 2 is defined as the X direction, the direction perpendicular to the X direction is defined as the Y direction, and the height direction of the first heat exchange tube 3 and the second heat exchange tube 4 is defined as the Z direction.

[0060] In some embodiments, the first heat exchange tubes 3 are arranged in two rows along a direction perpendicular to the alternating arrangement of the first heat exchange tubes 3 and the second heat exchange tubes 4, that is, along the Y direction perpendicular to the X direction, and the first medium between the two rows of first heat exchange tubes 3 is conducted.

[0061] The second heat exchange tube 4 is configured as a wide flat tube, and the first heat exchange tube 3 is configured as a narrow flat tube. In the case of configuring a second heat exchange tube 4 with a wide flat tube, two or three or more first heat exchange tubes 3 with narrow flat tubes may be configured accordingly. Of course, in this embodiment, only the first heat exchange tube 3 with two narrow flat tubes is used as an example for description.

[0062] When the second heat exchange tube 4 is set as a wide flat tube and the first heat exchange tube 3 is set as a narrow flat tube, and the upper end of the first heat exchange tube 3 is connected to the second liquid collecting chamber 12 and the lower end is connected to the fourth liquid collecting chamber 22, and the upper end of the second heat exchange tube 4 is connected to the first liquid collecting chamber 11 and the lower end is connected to the third liquid collecting chamber 21 as an example, at this time, an upper partition 19 is provided in the second liquid collecting chamber 12, and the upper partition 19 is extended along the X direction, and the upper partition 19 is provided between two adjacent rows of first heat exchange tubes 3, and is used to isolate the two rows of first heat exchange tubes 3. Of course, the ends of the first heat exchange tubes 3 in the same row located in the second liquid collecting chamber 12 are interconnected, and the upper partition 19 is provided with flow holes 6 for the circulation of the first medium, that is, the first heat exchange tubes 3 between rows are conducted through the flow holes 6 opened on the upper partition 19. A lower partition 23 is arranged in the fourth liquid collecting chamber 22, and the lower partition 23 is extended along the X direction. The lower partition 2 is arranged between two adjacent rows of first heat exchange tubes 3, and is used to isolate the two rows of first heat exchange tubes 3. The lower partition 23 divides the fourth liquid collecting chamber 22 into a first liquid inlet chamber 14 and a first liquid outlet chamber 15. The first inlet tube is arranged at one end of the lower collecting tube 2 and is correspondingly connected to the first liquid inlet chamber 14. The first outlet tube is arranged at one end of the lower collecting tube 2 and is correspondingly connected to the first liquid outlet chamber 15. Thus, the first medium enters the first liquid inlet chamber 14 through the first inlet pipe, and in the first liquid inlet chamber 14, the first medium is distributed to the first heat exchange tubes 3 in the same row along the X direction, and flows from the lower ends of the first heat exchange tubes 3 to the upper ends, that is, along the Z direction, and then all flows into the second liquid collecting chamber 12, and in the second liquid collecting chamber 12, the first medium flows along the Y direction, and then flows to the first heat exchange tubes 3 in the next row through the flow holes 6 on the upper partition 19, and then flows from the upper end of the first heat exchange tube 3 to the lower end, that is, along the Z direction, and then all flows into the first liquid outlet chamber 15, and the first medium in the first liquid outlet chamber 15 flows out through the first outlet pipe along the X direction. In this way, the flow direction of the first medium in the second liquid collecting chamber 12 is from the inside to the outside, that is, it flows along the Y direction. The flow direction of the first medium is just opposite to the direction of the air intake, and countercurrent contact is achieved. Through the reverse contact, the cooling and heat exchange performance can be improved. At the same time, the inner and outer double-row form is adopted, and the first medium in each row of the first heat exchange tubes 3 flows uniformly from the inside to the outside at the same time, which can ensure the uniformity of the front and rear air outlets, and effectively improve the cooling and heat exchange performance.

[0063] In the above-mentioned setting mode, a first partition 13 is arranged in the first liquid collecting chamber 11, and the first partition 13 divides the first liquid collecting chamber 11 into a second liquid inlet chamber 17 and a second liquid outlet chamber 18. The second inlet pipe is arranged at one end of the upper collecting pipe 1 and is correspondingly connected to the second liquid inlet chamber 17. The second outlet pipe is arranged at the other end of the upper collecting pipe 1 and is correspondingly connected to the second liquid outlet chamber 18. The upper ends of all second heat exchange tubes 4 located in the second liquid inlet chamber 17 are in a connected state, the upper ends of all second heat exchange tubes 4 located in the second liquid outlet chamber 18 are in a connected state, and the lower ends of all second heat exchange tubes 4 located in the third liquid collecting chamber 21 are in a connected state. Thus, the second medium enters the second liquid inlet chamber 17 through the second inlet pipe, and in the second liquid inlet chamber 17, the second medium is distributed to the plurality of second heat exchange tubes 4 from left to right along the X direction, and flows uniformly from the upper ends of the plurality of second heat exchange tubes 4 to the lower ends, and then all flows into the third liquid collecting chamber 21, and in the third liquid collecting chamber 21, the second medium flows from left to right along the X direction, and flows from the lower ends of the second heat exchange tubes 4 to the upper ends, that is, along the Z direction, and then all flows into the second liquid outlet chamber 18, and then flows out through the second outlet pipe.

[0064] In one example, an upper transverse partition 7 is provided in the upper manifold 1, and the interior of the upper manifold 1 is divided into two layers, namely, the first liquid collecting chamber 11 and the second liquid collecting chamber, by the upper transverse partition 7. The upper partition 19 is connected to the lower surface of the upper transverse partition 7 and the bottom of the upper partition 19 abuts against the bottom of the second liquid collecting chamber 12. The top of the first partition 13 is connected to the top of the first liquid collecting chamber 11 and the bottom abuts against the upper surface of the upper transverse partition 7. Thus, the upper partition 19 and the upper transverse partition 7 can be made into a whole, and the whole can be detachably connected in the upper manifold 1, thereby realizing convenient assembly. At the same time, the upper partition 19 is set in a disconnected manner along its length direction, that is, it is set in multiple pieces, and the space between two adjacent upper partitions 19 is just enough for the second heat exchange tube 4 to be inserted.

[0065] A lower transverse partition 8 is provided in the lower collecting pipe 2, which divides the interior of the lower collecting pipe 2 into two layers, namely the third collecting chamber 21 and the fourth collecting chamber 22. The lower transverse partition 8 can also be assembled in the lower collecting pipe 2 in a detachable manner.

[0066] Of course, the second heat exchange tube 4 can also be set as a narrow flat tube and set in two rows, and the first heat exchange tube 3 can be set as a wide flat tube. In this case, the upper partition 19 is set in the first liquid collecting chamber 11, and the upper partition 19 is set between two adjacent rows of second heat exchange tubes 4. The lower partition 23 is set in the third liquid collecting chamber 21, and the lower partition 23 divides the third liquid collecting chamber 21 into a second liquid inlet chamber 17 and a second liquid outlet chamber 18; the second inlet pipe is set at one end of the lower collecting pipe 2 and is correspondingly connected to the second liquid inlet chamber 17; the second outlet pipe is set at one end of the lower collecting pipe 2 and is correspondingly connected to the second liquid outlet chamber 18. Through this setting, the flow direction of the second medium is from the inside to the outside, that is, it flows along the Y direction, and the flow direction of the second medium is exactly opposite to the direction of the incoming air.

[0070] Implementation principle of this embodiment: In this embodiment, the warm air core and the cooling core are made into an integrated core, which can save space in the air-conditioning box and is lighter in weight. Compared with the independent structural form in the prior art, it reduces production costs and reduces the input of raw materials in production. At the same time, it is more convenient and easy to install. At the same time, the upper collecting pipe 1 and the lower collecting pipe 2 are both arranged in a double-layer form. The upper collecting pipe 1 and the lower collecting pipe 2 can be used as the collecting pipe of the first heat exchange tube 3 and the collecting pipe of the second heat exchange tube 4. When the first heat exchange tube 3 and the second heat exchange tube 4 both pass through a heat exchange medium or a cooling medium, they can be used in conjunction with the cooling core or the warm air core in an ordinary air-conditioning box.

[0071] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0072] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
