[0021] The utility model is further described below in conjunction with embodiments and drawings.

[0022] Embodiment 1:

[0023] like Figure 1-Figure 6 As shown, a water pump body with an integrated oil cooler mounting seat mainly includes a pump casing 1 and a rear cover 2 covered on the pump casing 1. Specifically, the connection between the rear cover 2 and the pump casing 1 has a plurality of first bolt connection seats 23 distributed along the circumferential outer edge, and the connection between the pump casing 1 and the rear cover 2 has second bolt connection seats corresponding to each first bolt connection seat 23 one by one. Each first bolt connection seat 23 is respectively locked with the corresponding second bolt connection seat by a bolt 8, which is simple and reliable, and ensures the sealing performance between the pump casing 1 and the rear cover 2.

[0024] In this embodiment, the pump casing 1 and the rear cover 2 are combined to form an impeller mounting cavity 3, and a pump seat 11 and a water pump inlet 12 connected to the impeller mounting cavity 3 are integrally formed on the pump casing 1. A water pump outlet 111 connected to the impeller mounting cavity 3 is provided on the pump seat 11. The coolant in the coolant circulation loop enters the impeller mounting cavity 3 from the water pump inlet 12, and then flows out through the water pump outlet 111.

[0025] An oil cooler mounting seat 13 is integrally formed on the pump housing 1. In actual application, the oil cooler is directly integrated and mounted on the integrated oil cooler mounting seat 13, thereby improving the integration of the equipment and reducing the occupation of the installation space.

[0026] At the same time, a water inlet groove 131, a water return groove 132, an oil inlet groove 133 and an oil return groove 134 are provided on the oil cooler mounting seat 13, an oil inlet port 112 and an oil return port 113 are provided on the pump seat 11, and a water return channel 14, a water inlet channel 15, an oil inlet channel 16 and an oil return channel 17 are provided on the pump housing 1, wherein the water return channel 14 connects the water pump water inlet 12 and the water return groove 132, the water inlet channel 15 connects the water pump water outlet 111 and the water inlet groove 131, the oil inlet channel 16 connects the oil inlet 112 and the oil inlet groove 133, and the oil return channel 17 connects the oil return port 113 and the oil return groove 134.

[0027] The coolant at the water pump outlet 111 can flow through the oil cooler through the water inlet channel 15 and the water inlet groove 131 in sequence, and after completing the heat exchange with the lubricating oil, it can flow back to the water pump inlet 12 through the return groove 132 and the return channel 14 in sequence; the lubricating oil in the coolant circulation loop can flow through the oil cooler through the oil inlet 112, the oil inlet channel 16 and the oil inlet groove 133 in sequence, and after completing the heat exchange with the coolant, it can return to the coolant circulation loop through the return oil groove 134, the return oil channel 17 and the return oil port 113 in sequence. Therefore, through the above structural design, the connection between the oil cooler and the coolant circulation loop and the lubricating oil circulation loop is achieved without pipelines, which greatly reduces the possibility of oil leakage or coolant leakage and improves the stability of system operation.

[0028] Furthermore, the oil inlet groove 133, the water return groove 132, the oil return groove 134 and the water inlet groove 131 are sequentially arranged on the oil cooler mounting base 13, and the grooves for the coolant and the grooves for the lubricating oil are alternately arranged, so that heat exchange can also be performed on the oil cooler mounting base 13, further improving the cooling performance of the lubricating oil.

[0029] Furthermore, the position where the water return channel 14 communicates with the water return groove 132 is located at one end of the water return groove 132, the position where the water inlet channel 15 communicates with the water inlet groove 131 is located at one end of the water inlet groove 131, the position where the oil inlet channel 16 communicates with the oil inlet groove 133 is located at one end of the oil inlet groove 133, and the position where the oil return channel 17 communicates with the oil return groove 134 is located at one end of the oil return groove 134. With such a design, the flow path of the coolant and the lubricating oil on the oil cooler mounting seat 13 is extended, thereby further improving the heat exchange capacity, and further improving the cooling performance of the lubricating oil.

[0030] In this embodiment, the outer end surface of the oil cooler mounting base 13 is a plane structure, and a plurality of bolt connection holes 135 are provided along the circumferential outer edge of the oil cooler mounting base 13. Therefore, the oil cooler can be reliably fixed by connecting bolts, which is simple and reliable.

[0031] Furthermore, a plurality of weight-reducing grooves 136 are formed on the outer end surface of the oil cooler mounting base 13 , which reduces the overall weight while ensuring the structural strength of the oil cooler mounting base 13 , thereby meeting the lightweight design requirements.

[0032] Embodiment 2:

[0033] See also Figure 1-Figure 6 A mechanical water pump comprises an impeller shaft 4, an impeller 5, a pulley 6 and a water pump body with an integrated oil cooler mounting base of Example 1. The pulley 6 is synchronously rotated and sleeved on the outer end of the impeller shaft 4. The inner end of the impeller shaft 4 is inserted into the impeller mounting cavity 3 from the rear cover 2 and is synchronously rotated and sleeved with the impeller 5. Therefore, the pulley 6 can drive the impeller 5 to rotate synchronously with it through the impeller shaft 4.

[0034] At the same time, in order to ensure reliable installation of the impeller shaft 4 , an impeller shaft mounting sleeve 21 adapted to the impeller shaft 4 is integrally formed on the rear cover 2 , and the impeller shaft 4 is rotatably inserted into the impeller shaft mounting sleeve 21 via the bearing 7 .

[0035] Furthermore, in order to improve the structural strength of the impeller shaft mounting sleeve 21, a plurality of triangular support ribs 22 connected to the rear cover 2 are arranged along the circumference of the impeller shaft mounting sleeve 21, thereby avoiding deformation or damage of the impeller shaft mounting sleeve 21 after long-term high-intensity operation.

[0036] In addition, a sealing ring is provided between the pump housing 1 and the rear cover 2, and a water seal is provided between the impeller shaft 4 and the impeller shaft mounting sleeve 21, thereby ensuring the sealing performance of the mechanical water pump and avoiding the problem of liquid leakage.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present invention. Under the guidance of the present invention, ordinary technicians in this field can make a variety of similar expressions without violating the purpose and claims of the present invention, and such changes fall within the scope of protection of the present invention.
