Description

Technical Field

[0001] This application relates to the field of industrial cooling equipment technology, and in particular to an oil cooler. Background Technology

[0002] The function of an oil chiller is to lower the temperature of the hydraulic oil (cutting fluid, cooling water, etc.) in a machine tool, thereby ensuring that the machine tool can operate at a normal temperature, improving its service life and machining quality. The cooling process of an oil chiller involves heat exchange between the refrigerant and the high-temperature oil, achieved through repeated heat absorption and release via the evaporator and condenser. The internal structure of an oil chiller includes a compressor, condenser, evaporator, oil pump, expansion valve, and fan.

[0003] The cooling process of the oil cooler is as follows: low-temperature, low-pressure liquid refrigerant enters the evaporator, absorbs heat, and becomes low-temperature, low-pressure gas; the low-temperature, low-pressure gas enters the compressor and is compressed, becoming high-temperature, high-pressure gas; the high-temperature, high-pressure gas enters the condenser, releases heat, and becomes high-temperature, high-pressure liquid refrigerant; finally, the high-temperature, high-pressure liquid refrigerant enters the expansion valve for throttling, becoming low-temperature, low-pressure liquid, and then re-enters the evaporator. During this process, high-temperature oil to be cooled circulates within the evaporator, and the high-temperature oil is circulated through the oil pump to achieve the cooling effect.

[0004] Most existing oil coolers are frame structures. For example, Chinese patent CN211782069U, published on October 27, 2020, discloses an oil cooler with good cooling performance, including a housing, a compressor, a radiator, and a condenser, all housed within the housing and interconnected by a copper pipe. The housing is divided into a control box area, a heat dissipation area, a circulation component placement area, and a circulation oil tank by a panel. A control computer is housed in the control box area. A heat dissipation vent is provided through the housing at the front of the heat dissipation area, and the radiator is located inside the vent. The compressor is located in the circulation component placement area, which also houses a circulation oil pump. The condenser is located in the circulation oil tank. The system also includes an oil inlet and an oil outlet connected to the circulation oil pump. The oil inlet is located at the rear of the circulation oil tank, and the oil outlet is located at the rear of the circulation component placement area.

[0005] The aforementioned application, by placing the condenser in the circulating oil tank and dividing the housing into a control box area, a heat dissipation area, a circulation component placement area, and a circulating oil tank area using plates, can shorten the circulation pipes, increase the contact area with the cooling oil, reduce the manufacturing cost of the condenser housing, improve heat exchange efficiency, and simultaneously reduce the overall volume and space occupation. Regarding the related technologies mentioned above, the inventor believes that although this application can improve compactness, it will increase the difficulty of installing various components inside the housing, making installation inconvenient. In addition, the air filter screen in this application is only placed in the groove, and the vibration generated when the oil cooler moves or operates will cause dust on the air filter screen to fall into the groove, which is narrow and inconvenient to clean. Therefore, it is necessary to design an oil cooler that is easy to install and easy to clean. Utility Model Content

This application facilitates the connection between the lower and upper housings by setting multiple interconnected side plates and a top plate, and also facilitates the sequential installation of various internal components. By setting a connecting partition inside the upper housing, and connecting the connecting partition to two parallel side plates, the connecting partition can divide the interior of the upper housing into different spaces, which facilitates the installation of circuits and also enhances the connection strength between the side plates, ensuring overall stability. By setting a positioning component on the lower housing, and by having the connecting partition engage with the air filter, the air filter can be positioned and installed, preventing the air filter from becoming loose.

By setting positioning protrusions on both sides of the positioning component, the angle of the positioning component can be fixed, ensuring the support effect for the air filter and facilitating the cleaning of dust that falls on the lower housing.

[0019] 3. By bending both ends of the connecting partition, it is easy to connect the side panels and also easy to install and fix the movable door; by setting a positioning plate on the lower housing, the side panels can be installed and fixed through the positioning plate, which facilitates connection and fixation.
