Problems solved by technology

[0003] In the above-mentioned water pump cooling device, in order to lead the coolant in the water jacket of the engine block to the water collecting device, it is necessary to set the water inlet pipe group on the water collecting device. However, due to the structural design of the valve group in the prior art, there is a valve group design in the form of rotation. Due to the vibration of the vehicle during operation, it is easy to cause the valve group and the water inlet pipe group to The position deviation of the water inlet pipe group makes the control of the water inlet pipe group inaccurate, which affects the cooling effect of the engine

Embodiment 1

[0035] This embodiment relates to an engine water pump cooling device, which consists of figure 1 As shown, its structure includes a water pump 1, a water collecting device 2 arranged before the pump of the water pump 1, and a pumping pipeline not shown in the figure arranged after the pump of the water pump 1, wherein the water collecting Device 2 is mainly used to accommodate the coolant flowing out of the water jacket of the engine block, while the water pump 1 pumps the coolant in the water collecting device 2 to the water jacket of the engine block again through the pumping pipeline. figure 1 The outlet 101 of the shown water pump 1 is communicated.

[0036] The water collecting device 2 of this embodiment includes a housing 201, the housing 201 is hollow inside and sealed on the left side, and figure 1 The right end of the housing 201 in the state shown, the inside of the housing 201 communicates with the water pump 1 , so that the coolant in the housing 201 can be deli...

Embodiment 2

[0042] This embodiment relates to an engine cooling system, which is an application of the engine water pump cooling device described in Embodiment 1, such as image 3 The figure shows the engine block water jacket 5 in the structure of the present embodiment, and the engine water pump cooling device of the first embodiment is connected with the engine block water jacket 5 . Specifically, the water collecting device 2 of the engine water pump cooling device communicates with the engine block water jacket 5 through the return water assembly. In this embodiment, the return water assembly mainly includes a radiator 6 connected to the water outlet of the engine block water jacket 5, an oil cooler 7, a warm air core 8, and a connection between the return water assembly and the engine block water jacket 5. The pipeline between the room, the return water assembly and the water collection device 2.

[0043] Among them, by image 3 As shown, the first coolant delivery pipeline of the...

Embodiment 3

[0053] This embodiment also relates to an engine water pump cooling device, which consists of Figure 4 As shown, it is basically the same as Embodiment 1, the difference is that the water inlet pipe set 3 in this embodiment only includes the warm air return pipe 301 communicating with the housing 201, the machine cooling return pipe 302, and the radiator return pipe 303 1. The small circulation water return pipe 304 directly connected with the water jacket of the engine cylinder body saves the back water pipe after the pump; in the corresponding valve group, the back water valve body behind the pump is also omitted.

Abstract

The invention provides a cooling device for a water pump of a motor. The cooling device comprises the water pump, a water collection device arranged in front of the water pump and a pumping pipe arranged behind the water pump. The water collection device comprises a casing with the inner portion communicated with the water pump. A water inlet pipe group communicated with the inner portion of the casing and conveying cooling liquid in a water jacket of a motor cylinder is arranged on the casing. A valve plug driven by a power device to move in the casing in the axial direction is arranged in the casing. A water inlet valve group capable of closing or opening the water inlet pipe group along with movement of the valve plug is arranged on the valve plug. The water inlet valve plug group disposed on the valve plug moves in the axial direction so that the stability of the water inlet valve group during movement can be effectively improved, opening and closing of a water return pipe are more accurate, and the cooling effect of the motor is guaranteed. Meanwhile, the invention further relates to a motor cooling system with the cooling device and a vehicle with the motor cooling system.

Description

technical field [0001] The invention relates to the technical field of vehicle engine cooling, in particular to an engine water pump cooling device; at the same time, the invention also relates to an engine cooling system with the engine water pump cooling device and a vehicle with the system. Background technique [0002] Effectively controlling the thermal state of the engine is an important way to reduce the fuel consumption of the engine and realize energy saving. Therefore, the engine cooling system should meet three conditions: one is to enable the engine to run at the set operating temperature; the other is that each component does not require additional energy compared with the traditional system; machine to insulate the system during warm-up. In the existing engine cooling system, its structure mainly includes a water pump cooling device connected to the water jacket of the engine block, which mainly circulates the cooling liquid in the water jacket of the engine b...
