DETAILED DESCRIPTION

[0036] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0037] It should be noted that the directions or positional relationships indicated by "front", "rear", "inside", "outside", "up" and "down" in this embodiment are based on the direction of the vehicle itself, where the head of the vehicle represents "front", the rear of the vehicle represents "rear", the top of the vehicle represents "up", and the bottom of the vehicle represents "down", the "inside" side refers to the side facing inside the cab, and the "outside" side refers to the side facing outside the cab.

[0039] Please also read Figure 1 and Figure 2Now, the vehicle double-layer condenser provided by the utility model is described. The vehicle double-layer condenser comprises a manifold group, a liquid inlet pipe 2 and a liquid outlet pipe 3, wherein the manifold group is extended in the up-down direction of the vehicle body; the manifold group comprises a first manifold 11 and a second manifold 12 arranged in the front-back direction of the vehicle body; a liquid inlet installation position 111 is provided on the first manifold 11, and a liquid outlet installation position 121 is provided on the second manifold 12; one end of the liquid inlet pipe 2 is connected to the liquid inlet installation position 111; one end of the liquid outlet pipe 3 is connected to the liquid outlet installation position 121; wherein, in the up-down direction of the vehicle body, the liquid inlet installation position 111 and the liquid outlet installation position 121 are not at the same height, and the diameter of the liquid inlet pipe 2 is greater than the diameter of the liquid outlet pipe 3.

[0040] It should be noted that in order to increase the heat exchange area in contact with the air, after the condenser in the prior art is installed, the collecting pipe group is extended along the up and down direction of the vehicle body. Therefore, this embodiment limits the collecting pipe group to be extended along the up and down direction of the vehicle body, which borrows the direction after the vehicle double-layer condenser is assembled, and is only for the convenience of explaining the installation positions of the liquid inlet pipe 2 and the liquid outlet pipe 3.

[0041] The liquid outlet end of the liquid inlet pipe 2 is connected to the liquid inlet installation position 111, and the liquid inlet end is connected to the compressor outlet. The compressor can output the refrigerant to the manifold group. The liquid inlet end of the liquid outlet pipe 3 is connected to the liquid outlet installation position 121, and the liquid outlet end is connected to the inlet of the throttling component. The refrigerant circulates in the vehicle double-layer condenser and enters the throttling component through the liquid outlet pipe 3.

[0042] The liquid inlet installation position 111 and the liquid outlet installation position 121 are not at the same height and are not on the same header, and the diameter of the liquid inlet pipe 2 is larger than the diameter of the liquid outlet pipe 3. Since the refrigerant flowing into the liquid inlet pipe 2 is a gaseous refrigerant, when the flow rate remains unchanged, the larger the diameter of the liquid inlet pipe 2, the lower the refrigerant flow resistance, thereby facilitating the refrigerant to circulate inside the header group.

[0043] Preferably, the diameter of the liquid inlet pipe 2 is 1.25-2 times the diameter of the liquid outlet pipe 3 .

[0044] In some embodiments, the liquid inlet installation position 111 and the liquid outlet installation position 121 can be used as follows: Figure 1 , Figure 2 and Figure 3 The structure shown, see Figure 1 , Figure 2 and Figure 3 The liquid inlet mounting position 111 is located in the axial middle part of the first collecting pipe 11, that is, the liquid inlet pipe 2 is installed in the axial middle part of the first collecting pipe 11; the liquid outlet mounting position 121 is located below the liquid inlet mounting position 111, that is, the liquid outlet pipe 3 is installed below the liquid inlet pipe 2, and the height difference between the liquid inlet mounting position 111 and the liquid outlet mounting position 121 is 1 / 6-1 / 5 of the height of the collecting pipe group.

[0045] The liquid inlet pipe 2 is installed in the axial middle part of the first header 11. After the refrigerant enters the first header 11 through the liquid inlet pipe 2, it can flow in the first header 11 in two paths, one upward and one downward. The liquid outlet pipe 3 is installed below the liquid inlet pipe 2, and the distance from the liquid outlet pipe 3 to the bottom surface of the header group is much greater than the distance to the liquid inlet pipe 2. The refrigerant flowing back to the second header 12 is also divided into two paths, one upward and one downward, and flows back to the liquid outlet pipe 3. Figure 3 shown.

[0046] Compared with the method of installing the liquid inlet pipe 2 / liquid outlet pipe 3 at the upper or lower part of the first collecting pipe 11, the liquid inlet pipe 2 is installed in the axial middle part of the first collecting pipe 11, the refrigerant is divided into two paths, and each refrigerant path does not need to flow through the entire collecting pipe group and the flat tube group, which reduces the temperature of the refrigerant returning to the liquid outlet pipe 3 and improves the heat exchange efficiency.

[0047] In some embodiments, the liquid inlet installation position 111 and the liquid outlet installation position 121 may also be Figure 2 The structure shown, see Figure 2 The liquid inlet installation position 111 is a liquid inlet hole opened on the first collecting pipe 11, and the liquid outlet installation position 121 is a liquid outlet hole opened on the second collecting pipe 12; one end of the liquid inlet pipe 2 extends into the liquid inlet hole and is welded to the liquid inlet hole; one end of the liquid outlet pipe 3 extends into the liquid outlet hole and is welded to the liquid outlet hole.

[0048] The liquid inlet pipe 2 is welded to the first collecting pipe 11, and the liquid outlet pipe 3 is welded to the second collecting pipe 12. The welding connection method is simple, and the transition structure for connecting the liquid inlet pipe 2 and the first collecting pipe 11, and the liquid outlet pipe 3 and the second collecting pipe 12 is omitted, thereby reducing the overall weight of the vehicle double-layer condenser.

[0049] In some embodiments, the above-mentioned double-layer condenser for vehicle can also be used as follows Figure 1 , Figure 2 and Figure 3 The structure shown, see Figure 1 , Figure 2 and Figure 3 The manifold group further includes a third manifold 13 and a fourth manifold 14 arranged along the front-rear direction of the vehicle body, the third manifold 13 corresponds to the first manifold 11 along the left-right direction of the vehicle body, and the fourth manifold 14 corresponds to the second manifold 12 along the left-right direction of the vehicle body;

[0050] The vehicle double-layer condenser also includes a first flat tube group 41, a second flat tube group 42 and a fin group 5. The first flat tube group 41 includes a plurality of first flat tubes spaced apart along the up-down direction of the vehicle body; one end of each first flat tube is inserted into the first header 11, and the other end is inserted into the second header 12. The second flat tube group 42 is spaced apart from the first flat tube group 41 along the front-to-back direction of the vehicle body; the second flat tube group 42 includes a plurality of second flat tubes spaced apart along the up-to-down direction of the vehicle body, and the plurality of second flat tubes correspond to the plurality of first flat tubes in the front-to-back direction of the vehicle body; one end of each second flat tube is inserted into the second header 12, and the other end is inserted into the fourth header 14; the fin group 5 includes a plurality of fins spaced apart along the up-to-down direction of the vehicle body, and the plurality of fins are sequentially arranged on the first flat tube group 41 and the second flat tube group 42 from top to bottom.

[0051] The first header 11 has the same structure as the second header 12 , and the third header 13 has the same structure as the fourth header 14 . The difference between the first header 11 and the third header 13 is that a flow hole is provided on the first header 11 or the third header 13 .

[0052] The first flat tube group 41 and the second flat tube group 42 are main heat exchange component groups. The first flat tube and the second flat tube have the same structure. Each of the first flat tube and each of the second flat tube is provided with a plurality of flow channels which are spaced apart along the width direction and pass through along the length direction. The flow channels are used for circulating refrigerant.

[0053] Each fin is folded and bent in a wave shape, and a fin is connected between two first flat tubes adjacent to each other and two second flat tubes corresponding to the two first flat tubes in front and behind. The fin group 5 is a key heat exchange component. The fin group 5 transfers the high temperature generated by the compression of the refrigerant in the first flat tube group 41 and the second flat tube group 42, and exchanges heat with the air, transferring the heat to the outside to achieve the purpose of heat exchange.

[0054] In some embodiments, the connection method of the header group can be as follows: Figure 3 and Figure 5 See the method shown in Figure 3 and Figure 5 The first collecting pipe 11 and the second collecting pipe 12 are isolated from each other; the side wall of the third collecting pipe 13 is in contact with the side wall of the fourth collecting pipe 14, and a plurality of first connecting holes 131 are provided on the side wall of the third collecting pipe 13 at intervals along the up-down direction of the vehicle body, and a plurality of second connecting holes 141 are provided on the side wall of the fourth collecting pipe 14 at intervals along the up-down direction of the vehicle body, and the plurality of second connecting holes 141 correspond to and are connected with the plurality of first connecting holes 131 one by one along the front-rear direction of the vehicle body.

[0055] The first header 11 and the second header 12 are isolated from each other, and the third header 13 and the fourth header 14 are connected to each other, so that the refrigerant forms a circulation flow in the vehicle double-layer condenser. Specifically, after the refrigerant enters the first header 11 from the liquid inlet pipe 2, it flows in two ways, then enters the third header 13 through the first flat tube, enters the fourth header 14 through the first connecting hole 131 and the corresponding second connecting hole 141, then flows back to the second header 12 through the second flat tube, and finally flows back to the throttling component through the liquid outlet pipe 3, such as Figure 3 The refrigerant releases heat when passing through the first flat tube and the second flat tube, and the heat is dissipated through the fin group 5.

[0056] In some embodiments, the above-mentioned header group can also be used as follows Figure 4 and Figure 5 The structure shown, see Figure 4 and Figure 5 The first header 11, the second header 12, the third header 13 and the fourth header 14 are respectively provided with a plurality of plug holes 15 spaced apart along the up-and-down direction of the vehicle body; wherein the plug holes 15 on the first header 11 and the plug holes 15 on the third header 13 are used for plugging in the first flat tubes, and the plug holes 15 on the second header 12 and the plug holes 15 on the fourth header 14 are used for plugging in the second flat tubes.

[0057] Limiting plates 16 are provided on the inner walls of the first collecting tube 11, the second collecting tube 12, the third collecting tube 13 and the fourth collecting tube 14 at the upper and lower edges of each insertion hole 15. The two limiting plates 16 of each insertion hole 15 are used to limit the first flat tube / the second flat tube along the upper and lower directions of the vehicle body.

[0058] The two ends of each first flat tube are correspondingly inserted into the insertion holes 15 of the first header 11 and the insertion holes 15 of the third header 13, and are preferably connected by welding. In addition, the ends of the first flat tubes are limited up and down by two limiting plates 16, which improves the fixing stability of the first flat tubes, and the two limiting plates 16 can also be welded to the ends of the first flat tubes, increasing the welding area and facilitating the welding operation.

[0059] The same effect is applicable to the second flat tube and the limiting plate 16 corresponding to the second flat tube.

[0060] In some embodiments, the above-mentioned header group can also be used as follows Figure 2 The structure shown, see Figure 2 The first header 11, the second header 12, the third header 13, and the fourth header 14 all penetrate the vehicle body in the up-down direction; and the upper and lower ends of the first header 11 and the second header 12, and the upper and lower ends of the third header 13 and the fourth header 14 are respectively provided with end covers 17.

[0061] Each end cover 17 includes an end plate and two bosses, and the two bosses of the end cover 17 corresponding to the first header 11 and the second header 12 are correspondingly inserted at the ends of the first header 11 and the second header 12. The two bosses corresponding to the third header 13 and the fourth header 14 are correspondingly inserted at the ends of the third header 13 and the fourth header 14. The end cover 17 is used to block the first header 11 and the second header 12, and the third header 13 and the fourth header 14 to prevent refrigerant leakage.

[0062] In some embodiments, the above-mentioned double-layer condenser for vehicle can also be used as follows Figure 2 The structure shown, see Figure 2 An upper side plate 61 is provided above the first flat tube group 41 and the second flat tube group 42; a lower side plate 62 is provided below the first flat tube group 41 and the second flat tube group 42. In the front-to-back direction of the vehicle body, the front edge of the upper side plate 61 is aligned with or exceeds the outer edge of the second flat tube, and the rear edge of the upper side plate 61 is aligned with or exceeds the outer edge of the first flat tube. The structure and installation position of the lower side plate 62 in the front-to-back direction of the vehicle body are the same as those of the upper side plate 61.

[0063] A fin is connected between the first flat tube and the second flat tube located at the top and the upper plate 61 , and a fin is also connected between the first flat tube and the second flat tube located at the bottom and the lower plate 62 .

[0064] The upper plate 61 and the lower plate 62 protect the fin group 5, the first flat tube group 41 and the second flat tube group 42 to prevent damage to the upper and lower fins, the upper and lower first flat tubes or the upper and lower second flat tubes due to collision during production and transportation.

[0065] Based on the same inventive concept, an embodiment of the present application also provides a vehicle, including the above-mentioned vehicle double-layer condenser.

[0066] The vehicle provided by the utility model adopts the above-mentioned vehicle-use double-layer condenser, which facilitates the full heat exchange of the refrigerant, improves the heat exchange capacity, and reduces the refrigerant flow resistance.

[0067] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
