[0039] The term "plurality" used in the present application refers to two or more (including two).

[0040] Reference below Figure 1-Figure 6 An intercooler 100 and a vehicle according to an embodiment of the present invention are described.

[0041] like Figure 1 As shown, the intercooler 100 according to the first embodiment of the present application includes: a core 10 and a shell 20.

[0042] Among them, Figure 6 As shown, the core 10 has a gas channel, the shell 20 surrounds the core 10, and defines a liquid channel with the core 10. During operation, the pressurized high-temperature gas flows through the gas channel, and the cooling medium (such as coolant, cooling medium, etc.) flows through the liquid channel. The heat exchange between the coolant and the pressurized high-temperature gas reduces the temperature of the gas entering the engine, thereby improving the working stability and reliability of the engine and avoiding engine misfire and damage.

[0043] Combination Figure 2 and Figure 3 As shown, the shell 20 of the embodiment of the present application is surrounded by a plurality of plates, and the shell 20 is generally a cubic structure. The air intake structure and the air outlet structure of the intercooler 100 are respectively formed on two opposite plates of the shell 20, so that the first plate 211 of the shell 20 is connected to the inlet end of the liquid channel, so that the cooling medium can enter the liquid channel to complete the heat exchange with the high-temperature gas.

[0044] Furthermore, at least one row of first flow channel holes a is provided on the first plate 211. In the first direction, the first flow channel holes a are arranged sequentially from the center line of the first plate 211 to the edge of the first plate 211, and the equivalent diameters of the plurality of first flow channel holes a gradually decrease in the direction away from the center line.

[0045] Specifically, one row, two rows or more rows of first flow channel holes a can be set on the first plate 211, and the multiple first flow channel holes a in each row are arranged in sequence in a first direction. The first direction can be the length direction, width direction or any direction of the first plate 211. Among the multiple first flow channel holes a arranged in sequence, the equivalent diameter of the first flow channel holes a adjacent to the center line of the first plate 211 is larger than the equivalent diameter of the first flow channel holes a away from the center line of the first plate 211, and in the direction away from the center line, the equivalent diameters of the multiple first flow channel holes a arranged in sequence gradually decrease.

[0046] It should be pointed out that the gradual decrease in the equivalent diameters of a plurality of first flow channel holes a arranged in sequence can be that the plurality of first flow channel holes a decreases in sequence, or the plurality of first flow channel holes a are equally divided into a plurality of groups in the first direction, the equivalent diameters of the plurality of first flow channel holes a in each group are consistent, and decrease in sequence between the plurality of groups.

[0047] The first flow channel hole a in the embodiment of the present application can be a circular hole or a non-circular hole, and the equivalent diameter means that when the first flow channel hole a in the present application is a non-circular hole, the diameter of a circular hole with the same radius as the cooling medium force is defined as the equivalent diameter of the non-circular hole.

[0048] It can be understood that the larger the equivalent diameter of the first flow channel hole a, the greater the flow rate per unit time, and the smaller the equivalent diameter of the first flow channel hole a, the smaller the flow rate per unit time. In this application, the equivalent diameter of the first flow channel hole a on both sides of the first direction is made smaller than the equivalent diameter of the first flow channel hole a in the middle position of the first direction, so that the cooling medium can flow from both sides of the first direction to the middle, and the flow in the middle area and on both sides can be made roughly consistent, the overall flow consistency is better, and the liquid flow uniformity is higher.

[0049] According to the intercooler 100 of the embodiment of the present application, by setting the first flow channel hole a on the first plate 211, and in the direction away from the center line, the equivalent diameters of the multiple first flow channel holes a arranged in sequence gradually decrease, so that the flow consistency in the liquid flow channel and the uniformity of the liquid flow can be improved, so that the heat exchange efficiency and heat exchange effect of the multiple liquid flow channels are similar, which can not only improve the cooling efficiency and cooling effect to reduce the probability of engine stalling and improve the working stability and reliability of the engine, but also avoid local overheating of the intercooler 100 and improve the working stability and reliability of the intercooler 100.

[0050] like Figure 2 and Figure 3 As shown, according to some embodiments of the present application, the first flow channel holes a are arranged in an array, and each column of the first flow channel holes a has at least two first flow channel holes, and each column of the first flow channel holes a corresponds to the same liquid channel.

[0051] Specifically, the first flow channel holes a can be arranged in multiple columns in the first direction and in multiple rows in the second direction, with at least two first flow channel holes a in each column and at least two rows in the second direction, so that each liquid channel can correspond to at least two first flow channel holes a, and at least one of the two first flow channel holes a is arranged according to the above-mentioned arrangement trend, so that the flow rates of the multiple liquid channels can be closer, and the overall heat exchange efficiency and heat exchange effect of the intercooler 100 are higher.

[0052] Exemplarily, the number of liquid channels is 15, the first flow channel holes a are 3 rows and 15 columns, and each column has three first flow channel holes a.

[0053] Furthermore, the hole center spacing between two adjacent rows of first flow channel holes a in the second direction gradually decreases in the direction away from the center line, and the first direction is orthogonal to the second direction.

[0054] It should be pointed out that the hole center spacing refers to the spacing between the hole center of the previous first flow channel hole a and the hole center of the next first flow channel hole a in two adjacent first flow channel holes a in the same row, and the hole center spacing adjacent to the center line is smaller, and the hole center spacing away from the center line is larger, and the equivalent diameter of the first flow channel hole a away from the center line is smaller, so that at least part of the cooling medium on both sides of the first plate 211 can flow to the middle area, so that the amount of cooling medium overflowing through the first flow channel hole a in the two side areas is closer to the amount of cooling medium overflowing through the first flow channel hole a in the middle area, so as to improve the flow uniformity, thereby improving the heat exchange effect and heat exchange efficiency.

[0055] In some embodiments, the first flow channel hole a is configured as an elliptical hole or an oblong hole.

[0056] That is to say, in some embodiments, the first flow channel hole a is constructed as an elliptical hole, and in other embodiments, the first flow channel hole a is constructed as an oblong hole. It is also possible to make a part of the first flow channel hole a constructed as an oblong hole and another part of the first flow channel hole a constructed as an elliptical hole, so that the first flow channel hole a is more narrow and long, which can not only correspond to the densely arranged liquid channels in the core body 10, but also reduce the flow resistance of the first flow channel hole a, increase the flow rate of each first flow channel hole a, and improve the cooling effect.

[0057] like Figure 2 and Figure 3 As shown, further, the size of the first flow channel hole a in the first direction is 2.5 mm to 3 mm.

[0058] Exemplarily, a dimension of the first flow channel hole a in the first direction is 2.5 mm, 2.6 mm, 2.7 mm, 2.8 mm, 2.9 mm or 3 mm, etc.

[0059] It should be pointed out that a plurality of liquid flow channels are arranged in sequence in the first direction, and each liquid flow channel is constructed as a flat tube structure, and the size of the flat tube in the first direction is 2.5mm~3mm, and the corresponding size of the first flow channel hole a in the first direction is also 2.5mm~3mm, which can not only increase the flow rate of the first flow channel hole a, but also make the size of the first flow channel hole a in the first direction similar to the size of the flat tube in the first direction, thereby improving the flow uniformity and making the sealing difficulty between the liquid flow channel and the first flow channel hole a (first plate 211) lower and the sealing effect better, thereby reducing the probability of leakage of the intercooler 100 and improving the working stability and reliability of the intercooler 100.

[0060] exist Figure 2 and Figure 3In the illustrated embodiment, according to some embodiments of the present application, the shell 20 includes: a first plate assembly 21 arranged at the inlet end of the liquid channel, the first plate assembly 21 includes: a first plate 211, a liquid inlet chamber 212 arranged on the first plate 211, and a liquid inlet pipe 213 installed in the liquid inlet chamber 212, and the liquid inlet chamber 212 is connected to the liquid channel through the first flow channel hole a.

[0061] Specifically, the first plate 211 and the other multiple plates of the shell 20 surround a cubic shell 20, and a liquid inlet chamber 212 is arranged on the first plate 211. A liquid inlet pipe 213 can be arranged on the liquid inlet chamber 212, that is, the liquid inlet pipe 213 supplies the cooling medium to the liquid inlet chamber 212. The liquid inlet chamber 212 can buffer the incoming cooling medium and improve turbulence. The cooling medium with more stable flow can be evenly diverted to multiple liquid channels under the action of multiple first flow channel holes a.

[0062] It can be understood that the liquid inlet chamber 212 can be constructed as a plate structure with a groove, and the plate can be fixed on the first plate 211 by laser welding and other processes, and the liquid inlet pipe 213 (such as screw connection, clamping connection, etc.) can be integrated and arranged on the corresponding area of ​​the bottom wall of the groove of the liquid inlet chamber 212. The first plate 211, the liquid inlet pipe 213, and the liquid inlet chamber 212 can be processed separately. After the processing is completed, they are assembled into components and the next step of assembly of the intercooler 100 is carried out. It can not only reduce the difficulty of assembly and improve production efficiency, but also simplify the structure of the water inlet area, so that the mold structure of the first plate 211, the liquid inlet chamber 212, etc. is simpler, the production reliability is higher, and the cost is lower.

[0063] like Figure 4 and Figure 5 As shown, further, the shell 20 also includes: a second plate assembly 22 arranged at the outlet end of the liquid channel, the second plate assembly 22 includes: a second plate 221, a liquid outlet chamber 222 arranged on the second plate 221, and an upper liquid outlet pipe 223 installed on the liquid outlet chamber 222.

[0064] Specifically, the first plate 211, the second plate 221 and the other multiple plates of the shell 20 surround a cubic shell 20, and a liquid outlet chamber 222 is arranged on the second plate 221, and a liquid outlet pipe 223 can be arranged on the liquid outlet chamber 222, that is, the cooling medium that completes heat exchange in multiple liquid channels can flow back to the liquid outlet chamber 222, and the liquid outlet chamber 222 can buffer the incoming cooling medium and improve turbulence, and the cooling medium with more stable flow can be discharged through the liquid outlet pipe 223.

[0065] It can be understood that the liquid outlet chamber 222 can be constructed as a plate structure with a groove, and the plate can be fixed on the second plate 221 by laser welding and other processes, and the liquid outlet pipe 223 (such as screw connection, clamping, etc.) can be integrated and arranged on the corresponding area of ​​the bottom wall of the groove of the liquid outlet chamber 222. The second plate 221, the liquid outlet pipe 223, and the liquid outlet chamber 222 can be processed separately. After the processing is completed, they are assembled into components and the next step of assembly of the intercooler 100 is carried out. It can not only reduce the difficulty of assembly and improve production efficiency, but also simplify the structure of the water outlet area, so that the mold structure of the second plate 221, the liquid outlet chamber 222, etc. is simpler, the production reliability is higher, and the cost is lower.

[0066] See also Figure 5 As shown, the second plate 221 is provided with second flow channel holes b arranged in an array, the liquid outlet chamber 222 is connected with the liquid channel through the second flow channel holes b, and the equivalent diameters of the plurality of second flow channel holes b are the same.

[0067] That is to say, the cooling medium that has completed heat exchange in multiple liquid channels can flow back to the liquid outlet chamber 222 through the second flow channel hole b, and the equivalent diameters of the multiple second flow channel holes b are similar, so that the outflow speeds of the cooling medium in the multiple liquid channels can be similar, so as to further improve the liquid circuit flow stability and uniformity of the intercooler 100, further improve the cooling effect, avoid blockage or slow flow rate of the cooling medium in a certain liquid flow channel, improve local overheating, and improve the reliability and stability of the intercooler 100.

[0068] Combination Figure 1 , Figure 2 and Figure 4 As shown, further, the first plate assembly 21 is arranged opposite to the second plate assembly 22, and the liquid inlet chamber 212 is located at one end of the shell 20 in the second direction, and the liquid outlet chamber 222 is located at the other end of the shell 20 in the second direction.

[0069] That is to say, projecting within the plane defined by the first direction and the second direction, the first plate assembly 21 is located at one end of the second direction, and the second plate assembly 22 is located at the other end of the second direction, so that the cooling medium can enter from one end of the shell 20 and flow out from the other end of the shell 20, extending the cooling medium flow path, making the heat exchange more complete, the heat exchange effect better, and the heat exchange efficiency higher.

[0070] Exemplarily, the first direction can be the width direction of the shell 20, the second direction can be the length direction of the shell 20, and at least one of the liquid inlet pipe 213 or the liquid outlet pipe 223 can be constructed as a bent pipe and bent along the height direction of the shell 20, so that the liquid inlet pipe 213 and the liquid outlet pipe 223 can extend to the same side of the shell 20, which is convenient for the liquid pipeline arrangement of the intercooler 100, making the arrangement of the intercooler 100 more compact, occupying less space, and less difficult to arrange.

[0071] The vehicle according to the second embodiment of the present application includes: the intercooler 100 in the above embodiment, which has the same technical effect as the above intercooler, and will not be repeated here.
