Description

TECHNICAL FIELD

[0001] The utility model belongs to hydraulic pump technical field, concretely relates to a quick cooling hydraulic pump. BACKGROUND

[0002] In the hydraulic transmission system, the hydraulic pump is the core component of energy conversion, responsible for converting mechanical energy into hydraulic energy, driving the entire hydraulic system to work. However, during high-speed operation, the hydraulic pump will generate a large amount of heat due to factors such as friction, pressure loss, and liquid compression. If this heat cannot be dissipated in time, it will cause the internal temperature of the hydraulic pump to rise, thereby affecting its working efficiency, reducing its service life, and even causing serious failures such as seal failure and oil deterioration. Therefore, the effective heat dissipation of the hydraulic pump has always been the focus of research in the field of hydraulic technology.

[0003] Traditionally, the heat dissipation methods of hydraulic pumps mainly include natural cooling and forced air cooling. Natural cooling relies on the natural convection of ambient air, and the heat dissipation effect is limited. Especially in high-intensity and long-time running conditions, it is difficult to meet the heat dissipation demand. Forced air cooling is to install a fan to force air to flow through the surface of the hydraulic pump to accelerate heat dissipation. Although this method has certain improvement compared with natural cooling, the heat dissipation effect of the fan will be greatly reduced in high-temperature environments.

[0004] In order to further improve the heat dissipation efficiency of the hydraulic pump, in recent years, some advanced heat dissipation technologies have been introduced into the hydraulic system, such as liquid cooling heat dissipation and heat pipe heat dissipation. Liquid cooling heat dissipation uses cooling water channels inside or outside the hydraulic pump to take away heat through the circulation of cooling liquid, which has a significant heat dissipation effect. However, the system is complex, the cost is high, and it requires certain modification of the structure of the hydraulic pump. SUMMARY

[0005] In view of the above problems, the purpose of the utility model is to provide a quick cooling hydraulic pump to solve the problem that the traditional heat dissipation method mainly uses natural cooling or simple fan blowing, the heat dissipation efficiency is limited, and it cannot meet the demand of high load and long time running.

[0013] The beneficial effect of the improvement is: the heat-conducting silicon grease coated at the joint of the hydraulic pump body and the heat conduction plate can improve the heat transfer efficiency between the hydraulic pump body and the heat conduction plate.

[0014] In order to make the air flow through the surface of the radiating fin to cool the condensing section of the heat pipe,

[0015] As the further improvement of the above technical scheme: the air inlet groove is arranged on the heat conduction plate between adjacent radiating fins, and the air inlet groove is located at the rear of the hydraulic pump body.

[0018] As the further improvement of the above technical scheme: the temperature sensor is installed on the radiating fin where the evaporating section of the heat pipe is located.

[0019] The beneficial effect of the improvement is: the temperature sensor can detect the temperature of the evaporating section of the heat pipe with high temperature, and relatively accurately detect the actual temperature of the hydraulic pump body.

[0020] In order to realize the automatic and rapid cooling of the hydraulic pump body,

[0021] As the further improvement of the above technical scheme: the temperature controller is electrically connected with the cooling fan and the temperature sensor.

[0022] The temperature sensor feeds back the temperature and sends a signal to the temperature controller, when the temperature exceeds the set threshold, the temperature controller controls the starting of the heat dissipation fan, the heat is quickly discharged, and rapid cooling is realized.
