Detailed Description
In order to make those skilled in the art better understand the technical solution of the present invention, the following detailed description will be provided with reference to specific embodiments.
As shown in fig. 1, an embodiment of the present invention provides a truck cooling system air release pipeline, which includes a first air release pipe and a second air release pipe 31, wherein one end of the first air release pipe is connected to an air release port 22 of an engine, and the other end of the first air release pipe is used for being connected to an expansion water bottle 61 of a cooling system; one end of the second air release pipe 31 is connected with the radiator 11, and the other end of the second air release pipe 31 is connected with one end of the first air release pipe close to the engine 21.
According to the truck cooling system air release pipeline provided by the embodiment of the invention, one end of the second air release pipe 31 is connected with the radiator 11, and the other end of the second air release pipe 31 is connected with one end, close to the engine 21, of the first air release pipe, so that the second air release pipe 31 is connected with the expansion kettle 61 through the rear-section pipeline of the first air release pipe, namely the rear-section pipeline of the first air release pipe is shared by the radiator 11 and the engine 21 during air release, the length of the second air release pipe 31 is effectively shortened, the mounting points of the pipeline are reduced, the first air release pipe and the second air release pipe 31 are easy to arrange, and the mounting of the cooling system air release pipeline is time-saving and labor-saving.
In an embodiment of the present invention, the truck cooling system air release pipeline further comprises a one-way valve 41, the one-way valve 41 is disposed on the second air release pipe 31, and the air in the second air release pipe 31 can flow to the first air release pipe through the one-way valve 41. With this scheme, due to the arrangement of the one-way valve 41, the passage of the first air-release pipe flowing to the second air-release pipe 31 is closed, so that the cooling liquid in the engine cannot flow to the radiator, and the second air-release pipe 31 can have a good exhaust effect; meanwhile, when the engine is in cold start, a part of the cooling liquid in the engine 21 cannot flow to the radiator through the second air release pipe, so that the temperature of the cooling liquid in the engine can be well ensured to be rapidly increased, and the starting and the exertion of the optimal performance of the engine are facilitated. It can be understood that when the engine is in cold start, the temperature of the coolant needs to be raised rapidly, and at the moment, the thermostat is in a closed state, the coolant needs to be ensured to circulate in the engine, and the temperature of the coolant can be raised rapidly without passing through a radiator; if the one-way valve is not arranged on the second air release pipeline, when the engine is in cold start, part of cooling liquid in the engine flows to the radiator through the air release port of the engine and the second air release pipeline, and after the cooling liquid is radiated by the radiator, the cooling liquid flows back into the engine again, so that the temperature of the cooling liquid is slowly increased, and the performance of the engine is influenced; thermostats are common components in engine cooling systems and are not described in detail herein.
It is preferable that the check valve 41 is disposed at one end of the second air-release pipe 31 close to the first air-release pipe, so that less coolant enters the second air-release pipe.
In another embodiment provided by the invention, the truck cooling system air release pipeline further comprises a control valve, the control valve is electrically connected with a controller of the cooling system, and the control valve is arranged on the second air release pipe; and when the engine is in cold start, the controller controls the control valve to close the second air release pipe. By adopting the scheme, when the engine is in cold start, namely the controller detects that the thermostat is closed, the control valve is closed, so that the cooling liquid only circulates in the engine and cannot flow into the radiator through the second air release pipe, the temperature of the cooling liquid in the engine can be ensured to rise rapidly, and the engine can be started and has better performance. It will be appreciated that the control valve may be left open at all times when the engine is not in a cold start condition to ensure the exhaust of gas from the radiator.
Specifically, the control valve is a normally open two-position two-way solenoid valve, such that when energized, the solenoid valve closes the second bleed line. It will be appreciated that the position of the control valve may be the same as the setting position of the one-way valve described above.
Further, the first air release pipe comprises a first connecting pipe 51, a second connecting pipe 52 and a three-way pipe, one end of the first connecting pipe 51 is connected with the air release port 22 of the engine, and the other end of the first connecting pipe 51 is connected with a first end of the three-way pipe; the second end of the three-way pipe is connected with one end, far away from the radiator, of the second air release pipe, and the third end of the three-way pipe is connected with the expansion kettle 61 through the second connecting pipe 52. By adopting the scheme, the structure of the first air leakage pipe is simpler, and meanwhile, the connection with the second air leakage pipe can be realized.
Specifically, the tee comprises a first pipe 53, a second pipe 54 and a third pipe 55, wherein the first pipe is horizontally arranged, and the left end of the first pipe 53 is connected with the first connecting pipe 51; the second pipe 54 comprises a horizontal pipe and a vertical pipe, the horizontal pipe is parallel to the first pipe 53, the left end of the horizontal pipe is connected with the second air release pipe, and the upper end of the vertical pipe is vertically connected with the right end of the horizontal pipe; the third pipe 55 is an L-shaped pipe, and the lower end of the vertical pipe and the right end of the first pipe are both connected with the left end of the horizontal section of the third pipe 55; the lower end of the vertical section of the third pipe 55 is connected with the upper end of the second connecting pipe, so that the connection with the first connecting pipe, the second connecting pipe and the second air release pipe is conveniently realized by using the three-way pipe. It will be appreciated that the left end of the first tube is the first end of the tee, the left end of the cross tube is the second end of the tee, and the lower end of the vertical section of the third tube is the third end of the tee.
Further, the first pipe 53 is detachably connected to the first connection pipe 51; the third pipe 55 is detachably connected to the second connection pipe 52, so that the three-way pipe, the first connection pipe and the second connection pipe can be conveniently replaced or maintained independently, and the maintenance cost is effectively reduced. Preferably, the second tube is detachably connected to the second air-release tube.
Preferably, the first pipe 53 and the second pipe 54 are formed in an integrated structure with the third pipe 55, so that the number of piping connections can be effectively reduced.
Specifically, the second air release pipe 31 is detachably connected with the first air release pipe, so that the second air release pipe can be replaced or maintained conveniently.
