Abstract

A water pump adapter seat that shares the functions of inlet and outlet thermostat belongs to the technical field of engine water pump adapter seats. Without exceeding the original engine boundary, this water pump adapter seat can achieve the switching between two states of inlet and outlet thermostat through different machining methods, minimizing the addition of cooling pipelines as much as possible. One end of the thermostat housing assembly is connected to one end of the thermostat cover, and the other end of the thermostat cover is connected to the radiator. The thermostat housing assembly is connected to one end of the inlet transfer pipe through the small-circulation return water steel pipe assembly. The other end of the inlet transfer pipe is connected to the water pump adapter seat, which is connected to the cylinder block through the water pump water channel and the cylinder block water inlet. The water pump adapter seat can adopt the form of machining or not machining the thermostat mounting surface to achieve the functions of inlet thermostat or outlet thermostat respectively. The present invention can reduce costs, shorten the lengths of the inlet and outlet pipelines, with relatively small pressure loss and reduced engine energy consumption.

[0002] Existing engine water pump adapter seats can only accommodate one cooling method, either inlet temperature control or outlet temperature control. When switching between the inlet and outlet temperature control states, the entire cooling system pipeline connection needs to be rearranged, increasing the cost of components. Summary of the Invention

[0003] The purpose of the present invention is to provide a water pump adapter seat that shares the inlet and outlet temperature control functions.

The water pump adapter seat adopts the form of machining or not machining the thermostat mounting surface to respectively achieve the functions of inlet temperature control or outlet temperature control.

[0005] The present invention has the following beneficial effects compared with the prior art:

[0006] The water pump adapter seat of the present invention can respectively achieve the functions of inlet temperature control and outlet temperature control by differentiating the machining method. There is no need to rearrange the entire cooling system pipeline. Only a few components need to be changed to achieve the switching between the inlet and outlet water. This reduces the pipeline layout during the switching of the inlet and outlet temperature control states of the cooling system, reduces costs, shortens the length of the inlet and outlet pipelines, has a small pressure loss, and reduces the energy consumption of the engine.

[0014] In order to better understand the purpose, structure and function of the present invention, the following further describes the present invention in detail with reference to the drawings.

[0015] Refer to Figures 1 to 6 As shown, a water pump adapter seat sharing the inlet and outlet thermostats of the present invention includes an inlet transfer pipe 1, a water pump adapter seat 2, a small circulation return water steel pipe assembly 3, a thermostat cover 4, a thermostat seat assembly 5 and a thermostat; one end of the thermostat seat assembly 5 is communicated with the thermostat cover 4, the other end of the thermostat cover 4 is communicated with the radiator, the thermostat seat assembly 5 is connected to one end of the inlet transfer pipe 1 through the small circulation return water steel pipe assembly 3, the other end of the inlet transfer pipe 1 is connected to the water pump adapter seat 2, and the water pump adapter seat 2 is communicated with the cylinder block through the water pump water channel and the cylinder block water inlet 6. The water pump adapter seat 2 adopts a form with or without machining the thermostat installation surface to respectively realize the functions of inlet thermostat or outlet thermostat.

[0016] When in the outlet thermostat state: without machining the thermostat installation surface of the water pump adapter seat 2, the thermostat is arranged in the thermostat seat assembly 5 and the thermostat cover 4 and sealed by a rubber ring. When the coolant temperature is lower than the thermostat opening temperature, the thermostat is closed, and the coolant flows through the thermostat seat assembly 5 and the small circulation return water steel pipe assembly 3, enters the inlet transfer pipe 1, and enters the cylinder block through the water pump water channel and the cylinder block water inlet 6 on the water pump adapter seat 2 to realize a small circulation; when the water temperature reaches the thermostat opening temperature, the thermostat opens, and the coolant flows through the thermostat cover 4 into the radiator. The water pump adapter seat 2 does not machine a thermostat installation boss and is sealed with the inlet transfer pipe 1 by a gasket. The cold coolant passing through the radiator enters the cylinder block through the inlet transfer pipe 1, the water pump water channel and the cylinder block water inlet 6 on the water pump adapter seat 2 to realize the function of outlet thermostat, and the cycle repeats.

[0017] When in the inlet thermostat state: machine the thermostat installation surface of the water pump adapter seat 2 on the inlet transfer pipe installation surface of the water pump adapter seat 2, arrange the thermostat between the water pump adapter seat 2 and the inlet transfer pipe 1. When the water temperature reaches the thermostat opening temperature, the thermostat opens, and the coolant enters the water pump adapter seat 2 through the inlet transfer pipe 1, and enters the cylinder block through the water pump water channel and the cylinder block water inlet 6 to realize the large circulation cooling of the inlet thermostat.
