[0002] For a supercharged engine, an intercooler is an important part of the supercharging system. The intercooler is an efficient radiator, and its main function is to reduce the temperature of the high-temperature gas after supercharging, so as to reduce the heat load of the engine, increase the intake air volume, and thus increase the power of the engine.

[0003] In the existing intercooler, in order to prevent the generation of intake air condensate, a thermostat is generally arranged in the intercooler. For example, in a mechanism for preventing the generation of intake air condensate disclosed in the publication number: CN219529136U, it includes a thermostat seat. One end of the thermostat seat is provided with a coolant inlet at the bottom, one side of the top of the thermostat seat is provided with a coolant outlet, and the other side of the top of the thermostat seat is provided with a coolant bypass interface. The thermostat seat is sequentially provided with a coolant inlet chamber, a coolant bypass chamber, and a coolant outlet chamber. A communication pipe communicating with the coolant inlet chamber is arranged in the coolant bypass chamber. The other end of the thermostat seat is inserted with a thermostat, and the temperature probe of the thermostat protrudes from the end face of the other end of the thermostat seat.

[0004] In this patent, in order to prevent water and gas from moving between the supercharged air chamber and the cooling water chamber, only a single-layer sealing structure is arranged between the thermostat and the thermostat seat to achieve water and gas isolation. The sealing effect of the single-layer sealing structure is poor. When the sealing ring is damaged, it is easy to cause water and gas to cross each other, resulting in the problem of engine damage.

The thermostat sealing ring is inserted into the convex block, and the sealing ring is located between the temperature control base, the convex block and the thermostat sealing ring.

[0008] Further, a first inclined surface with a gradually decreasing diameter is provided on the inner side of the convex block.

When one of the sealing rings 6 is damaged, the other sealing ring 6 can still maintain the seal, still ensuring that water and gas do not cross - flow, ensuring the normal operation of the engine and extending the service life of the engine.

[0023] In this embodiment, a convex block 9 protruding from the end face of the temperature - regulating base 1 is provided on one side of the temperature - regulating base 1. The thermostat sealing ring 3 is inserted into the convex block 9, and the sealing ring 6 is located between the temperature - regulating base 1, the convex block 9 and the thermostat sealing ring 3. The height of the convex block 9 protruding on the temperature - regulating base 1 is adapted to the thermostat sealing ring 3; by increasing the height of the convex block 9, the length of the thermostat sealing ring 3 increases accordingly, and more outer ring grooves 4 and inner ring grooves 5 can be provided on the thermostat sealing ring 3, thereby enhancing the sealing effect of the thermostat sealing ring 3.

[0024] In this embodiment, a first inclined surface 10 with a gradually decreasing diameter is provided inside the bump 9, and a second inclined surface 11 adapted to the first inclined surface 10 is provided on the thermostat sealing ring 3. The sealing rings 6 are distributed on both sides of the second inclined surface 11. When the thermostat sealing ring 3 is inserted into the bump 9, the first inclined surface 10 forms a limit. Without the need for the operator to finely adjust the installation depth of the thermostat sealing ring 3 after installing the thermostat sealing ring 3 into the thermostat seat 1, the installation time is shortened, the installation efficiency is effectively improved, and it is convenient to align the first channel 7 with the second channel 8, so that the first channel 7 is communicated with the second channel 8, thereby enabling the damage of the sealing ring 6 to be detected in time.
