Principle of operation
After passing through a supercharger, gas with certain pressure enters a front air passage 103 from an air inlet 101 of a intercooler 100, the gas entering the front air passage 103 is divided into two paths, and one path of gas directly enters a hot cavity 112 of a temperature regulating valve mounting hole 110; the other path of gas enters the wedge-shaped gas channel 105 through the cooling device 106 and then enters the cold chamber 114 of the temperature regulating valve mounting hole 110 through the rear gas channel 104 from the gas hole of the lower valve core sealing seat 115.
In an initial state, the valve core 201 of the temperature regulating valve 200 is in a closed state under the action of the valve core resetting device, the top end of the valve core 201 is attached to the upper seal seat 226 of the valve core, the gas in the hot cavity 112 is isolated at the outer side of the valve core 201, and the gas in the cold cavity 114 sequentially passes through the valve core 201 and the lower shell 205, enters the mixing cavity 111, and then enters the engine cylinder from the gas outlet 102 of the intercooler 100.
When the inter-cooling temperature needs to be adjusted, a running computer (ECU) sends a control command to the temperature adjusting valve 200 on the inter-cooling device 100, and the axial motor 203 on the temperature adjusting valve 200 pushes the valve core 201 to move up and down.
When the temperature rises, the axial motor 203 pushes the valve core 201 to move downwards, the valve core 201 leaves the valve core upper sealing seat 226 and moves towards the valve core lower sealing seat 115, the channel between the hot cavity 112 and the mixing cavity 111 is gradually opened, the channel between the cold cavity 114 and the mixing cavity 111 is gradually reduced, and a large amount of uncooled gas directly enters the mixing cavity 111 and is discharged from the gas outlet hole 102 of the intercooler 100 and enters an engine cylinder.
When the temperature is reduced, the axial motor 203 returns, the valve rod 202 drives the valve core 201 to move upwards under the action of the valve core resetting device, the channel between the cold cavity 114 and the mixing cavity 111 at the lower part of the valve core 201 is gradually enlarged, the channel between the hot cavity 112 and the mixing cavity 111 is gradually reduced, a large amount of cooled gas enters the mixing cavity 111, the temperature is reduced, and the cooled gas is discharged from the air outlet hole 102 of the intercooler 100 and enters an engine cylinder.
When the vehicle enters a rainy season or the whole vehicle runs in a high-humidity area, the compressed high-temperature and high-humidity gas passes through the cooling device 106 of the intercooler 100, and the water vapor is condensed into fine water drops to be attached to the wall surface of the cooling pipeline 108. This application sets cooling tube 108 to vertical arrangement structure, and the drop of water of condensation partly freely falls into lower part wedge air flue 105, and another part is driven by high-speed gas flow and gets into in lower part wedge air flue 105 along the flow direction of gas to the gathering is in the lower extreme of wedge air flue 105, and when the comdenstion water gathering liquid level reaches a certain position, the floating valve core 217 of automatic drain valve 107 on the wedge air flue 105 is opened under the effect of buoyancy and is turned on the water.
