[0033] It should be noted that the features in the embodiments of the utility model can be combined with each other without conflict.

[0034] In the related art, when the gas pressurized by the engine enters the intercooler, the gas flow rate is fast, and due to the large number of fins inside the intercooler and the uneven distribution, the flow of the gas between the fins is uneven, thereby affecting the cooling effect. Specifically, after the high-temperature and high-pressure gas pressurized directly enters the intercooler, its high-speed flow characteristic causes uneven distribution of the gas between the fins, and the gas flow rate in some areas is too high, while the gas flow rate in other areas is too low. This uneven flow rate distribution can cause the cooling fins in some areas to not fully exert their cooling effect, thereby reducing the overall cooling efficiency.

[0035] Therefore, how to improve the flow uniformity of the gas in the intercooler to improve the cooling efficiency has become a technical problem to be solved at present.

[0036] To solve the above problems, the utility model provides an intercooler 100 which can ensure uniformity of the intake air, thereby improving the cooling efficiency, and thus can improve the problem of non-uniform intake of the gas in the intercooler 100.

[0037] The utility model also provides an automobile, which comprises a vehicle body and a power system, the power system is installed on the vehicle body and used to provide power to the vehicle body. Specifically, the power system comprises an engine and an intercooler 100, the gas outlet chamber 40 of the intercooler 100 is connected with the engine of the power system, the intercooler 100 is used to cool the gas and deliver the cooled gas to the inside of the engine, thereby reducing the thermal load of the engine and improving the power of the engine.

[0038] Understandably, the power system further comprises a transmission system, a fuel supply system, an exhaust system and an electrical system, the engine, the intercooler 100, the transmission system, the fuel supply system, the exhaust system and the electrical system work together.

[0039] The overall structure, working principle and technical effects of the intercooler 100 are described in detail below through embodiments and in combination with the drawings.

[0040] It can be understood that the intercooler 100 is a device for reducing the temperature of air entering the engine cylinder. It is mainly used in a turbocharged or mechanically supercharged internal combustion engine system to improve the intake efficiency and engine performance. The intercooler 100 increases the intake density by reducing the intake temperature, thereby improving the output power and combustion efficiency of the engine.

[0041] The intercooler 100 provided in the embodiment is mainly applied to the power system of an automobile. In other embodiments, the intercooler 100 can also be applied to the power system of a motorcycle or a ship, etc. to enhance the power output, which is not specifically limited here.

[0042] Please refer to Figures 1-3 The intercooler 100 includes a cooling chamber 10, an intake chamber 20, a partition plate 30 and an outlet chamber 40. The outlet 202 of the intake chamber 20 is communicated with the cooling chamber 10. The partition plate 30 is arranged in the intake chamber 20 and is used to separate the intake chamber 20 into a plurality of intake channels. The plurality of intake channels are used to respectively pass in gas and make the gas enter the cooling chamber 10 for cooling. The outlet chamber 40 is communicated with the cooling chamber 10 and is connected with the engine, and is used to pass in the cooled gas and make the cooled gas enter the engine.

[0043] In the embodiment, the cooling chamber 10 includes an outer shell 11 and a heat dissipation fin 12. The heat dissipation fin 12 is installed in the outer shell 11. The outer shell 11 is communicated with the outlet 202 of the intake chamber 20. The inlet and outlet of the heat dissipation fin 12 are respectively communicated with the intake chamber 20 and the outlet chamber 40. After the gas in the intake chamber 20 enters the heat dissipation fin 12, the heat dissipation fin 12 takes away the heat in the gas by increasing the surface area in contact with the air, so as to achieve the purpose of cooling the gas. The cooled gas is passed into the outlet chamber 40 and finally enters the engine.

[0044] It can be understood that the heat dissipation fin 12 has a plurality of fins. Adjacent two fins form a heat dissipation channel therebetween, so as to Figure 2The relative positions in the drawings are described, and the plurality of fins are arranged in sequence in the up-down direction. In the prior art, when the intercooler is used, the gas entering the air inlet chamber is easy to concentrate on the lower side of the air inlet chamber, resulting in that a large amount of gas is concentrated in the heat dissipation channels on the lower side of the heat dissipation fins, and the gas in the heat dissipation channels on the upper side of the heat dissipation fins is less, thereby causing the gas in the whole heat dissipation fins to be unevenly distributed, the gas on the lower side of the heat dissipation fins cannot be completely cooled, and the overall cooling efficiency is reduced. In order to solve this technical problem, the intercooler 100 provided in the embodiment is used, and a baffle 30 is arranged in the air inlet chamber 20. The baffle 30 divides the inside of the air inlet chamber 20 into a plurality of air inlet channels. Each air inlet channel can pass the gas and make the gas enter the cooling chamber 10 for cooling through the plurality of air inlet channels. The plurality of air inlet channels can disperse the gas, so that the gas enters the cooling chamber 10 for cooling more uniformly. The baffle 30 in the air inlet chamber 20 can ensure the air inlet uniformity, thereby improving the cooling efficiency.

[0045] It should be noted that the two sides of the baffle 30 are a first side 301 and a second side 302, respectively. The first side 301 and the second side 302 form a first air inlet channel and a second air inlet channel with the inner wall of the air inlet chamber 20, respectively. The first air inlet channel and the second air inlet channel can shunt the gas in the air inlet chamber 20, avoid the gas from concentrating on the lower side of the air inlet chamber 20, the gas in the first air inlet channel can enter the lower side of the cooling chamber 10 for cooling, and the gas in the second air inlet channel can enter the upper side of the cooling chamber 10 for cooling, thereby ensuring the air inlet uniformity and improving the cooling efficiency.

[0046] Please refer to Figure 2 , the first air inlet channel and the second air inlet channel are arranged in sequence in the air inlet direction of the air inlet chamber 20.

[0047] In the embodiment, the cross-sectional area ratio of the first air inlet channel and the second air inlet channel is 1:1-1:3. Specifically, the cross-sectional area ratio of the first air inlet channel and the second air inlet channel is 1:2. In other embodiments, the cross-sectional area ratio of the first air inlet channel and the second air inlet channel can also be 1:1 or 1:3, which is not limited here.

[0048] Please refer to Figure 3 , the baffle 30 includes a first segment 31, a second segment 32 and a third segment 33 connected in sequence. The arrangement direction of the first segment 31 is parallel to the air inlet direction of the air inlet chamber 20, and the arrangement direction of the third segment 33 is parallel to the air inlet direction of the cooling chamber 10. The second segment 32 is an arc structure for guiding the gas on the first segment 31 to the third segment 33.

[0049] With Figure 3The relative position relationship in the figure is described as follows: the air inlet direction of the air inlet chamber 20 is the up-down direction, the air outlet direction of the air inlet chamber 20 is the front-rear direction, the first section 31 is arranged along the up-down direction, the first section 31 divides the air inlet 201 of the air inlet chamber 20 into two parts, the second section 32 can guide the gas entering the second air inlet channel to flow towards the third section 33, the third section 33 is arranged along the front-rear direction, and can guide the gas to enter the upper side of the cooling chamber 10, thereby increasing the amount of gas entering the upper side of the cooling chamber 10, and making the gas entering the upper side and the lower side of the cooling chamber 10 more uniform.

[0050] In order to change the flow direction of the gas in the air inlet chamber 20, the partition plate 30 is a curved surface structure, and the central angle corresponding to the partition plate 30 is 3°-8°. Specifically, the central angle corresponding to the partition plate 30 is 5°. In other embodiments, the central angle corresponding to the partition plate 30 can also be 3°, 6° or 8°, which is not limited here.

[0051] It also needs to be explained that in the prior art, after the gas enters the air inlet chamber, it will be concentrated in the lower side of the air inlet chamber, and the flow rate of the gas in the lower side of the air inlet chamber is faster than that in the upper side of the air inlet chamber. In order to keep the flow rate of the gas in the air inlet chamber uniform, the partition plate 30 in the embodiment is a curved surface structure. When the gas flows in the first air inlet channel, the gas flows along the first side 301 of the partition plate 30, the first side 301 of the partition plate 30 is expanded, and the flow rate of the gas can be reduced; when the gas flows in the second air inlet channel, the gas flows along the second side 302 of the partition plate 30, the second side 302 of the partition plate 30 is compressed, and the flow rate of the gas can be increased. Therefore, the arrangement of the partition plate 30 can reduce the flow rate of the gas in the first air inlet channel and increase the flow rate of the gas in the second air inlet channel, thereby ensuring that the flow rates of the gases in the first air inlet channel and the second air inlet channel are consistent, and further ensuring the cooling efficiency.

[0052] In the embodiment, the partition plate 30 and the air inlet chamber 20 are integrally formed. In other embodiments, the partition plate 30 can also be welded with the inside of the air inlet chamber 20, which is not limited here.

[0053] It can be understood that the air inlet 201 and the air outlet 202 of the air inlet chamber 20 are both circular structures, and the diameter of the air inlet 201 is smaller than that of the air outlet 202.

[0054] In summary, the intercooler 100, the power system and the automobile provided by the embodiment of the present application, the intercooler 100 comprises a cooling chamber 10, an air inlet chamber 20 and a partition plate 30, the air outlet 202 of the air inlet chamber 20 is communicated with the cooling chamber 10, the partition plate 30 is arranged in the air inlet chamber 20 and is used for separating the air inlet chamber 20 into multiple air inlet channels, and the multiple air inlet channels are used for respectively introducing gas and making the gas enter the cooling chamber 10 to be cooled. In use, the air outlet 202 of the air inlet chamber 20 is communicated with the cooling chamber 10, the air inlet chamber 20 can introduce gas, the gas enters the cooling chamber 10 to be cooled; the partition plate 30 arranged in the air inlet chamber 20 separates the air inlet chamber 20 into multiple air inlet channels, each air inlet channel can introduce gas and make the gas enter the cooling chamber 10 to be cooled via the multiple air inlet channels, the multiple air inlet channels can disperse the gas, so that the gas more uniformly enters the cooling chamber 10 to be cooled, and the partition plate 30 in the air inlet chamber 20 can ensure the air inlet uniformity, thereby improving the cooling efficiency.

[0055] The above is only a specific implementation manner of the present application, but the protection scope of the present application is not limited to this, any skilled person in the art can easily think of changes or replacements within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
