Oil coolers with small footprint have a high demand in mechanical production and processing, which can save space and are more popular for small and medium-sized enterprises with tight factory areas. Some components of processing equipment, such as the spindle and gearbox, generate a large amount of heat, and it is generally necessary to set up an oil cooler to cool down these heating components. Oil cooler uses the principle of evaporation and heat absorption of refrigerant for cooling work. The oil pump pumps the cooled oil medium from the oil cooler oil tank to the machine tool, machining center and other systems for heat exchange treatment, bringing back the heat in the system to the oil cooler for cooling and temperature reduction. By continuously circulating the oil medium, the oil temperature of the entire system is continuously reduced until it stabilizes within the controlled temperature range.

Traditional The refrigeration system of an oil cooler includes components such as a condenser, evaporator, and compressor. A fan is usually installed on the condenser, and the driving device for driving the fan is generally symmetrically arranged relative to the condenser. There is a certain amount of space on both sides of the driving device, but the space on both sides is not enough to place the evaporator, compressor, or other components of the oil cooler. Therefore, a separate frame structure needs to be set up above or elsewhere on the driving device to place the above components, resulting in a complex frame structure, inconvenient assembly, and the consumption of more raw materials. This also increases the volume and weight of the entire oil cooler, making transportation and installation very inconvenient
A low footprint oil cooler comprising a frame and a refrigeration system mounted on the frame, wherein the refrigeration system comprises a condenser and a fan mounted behind the condenser and adapted to the condenser. The frame is equipped with a driving device for driving the fan, which is laterally offset from the longitudinal symmetry plane of the condenser by a distance
The driving device comprises a motor, and the rotating shaft of the fan is directly connected to the output shaft of the motor. The center of the rotating shaft of the fan is laterally offset from the longitudinal symmetry plane of the condenser, and the outer edge of the fan is close to one side edge of the condenser. The condenser is a microchannel condenser. The refrigeration system also includes a compressor and an evaporator, wherein the compressor, condenser, and evaporator are sequentially connected end-to-end through refrigerant pipes for transporting refrigerant to form a circulation loop. The evaporator is a plate evaporator. A drying filter is installed on the refrigerant pipeline between the condenser and the evaporator, which is used to dry and filter the refrigerant transported from the condenser to the evaporator. There is also a fuel tank for storing cold oil on the rack, as well as an oil supply pipeline and a return pipeline for connecting the fuel tank with external oil equipment. The refrigeration system is located outside the oil tank and is connected to the oil tank through the return oil pipeline, used to cool the oil flowing from the return oil pipeline to the oil tank. There is an oil pump installed on the oil supply pipeline, which is driven by the driving device or driving device, and the oil pump is connected to the driving device or driving device through a coupling. A sensor for measuring the flow rate of oil in the return oil pipeline is installed on the return oil pipeline, which is located on the return oil pipeline between the refrigeration system and the oil tank
The driving device deviates laterally from the longitudinal symmetry plane of the condenser by a distance. The side of the driving device close to the longitudinal symmetry plane of the condenser can have sufficient space to place the compressor and other components of the oil cooler, without the need for an additional frame structure on the frame, making the structure of the frame simple and easy to process. The entire structure of the oil cooler is simple, compact, small in volume, and easy to transport and install
A low footprint oil cooler, comprising a frame 1 and a refrigeration system mounted on the frame 1. The refrigeration system includes a condenser and a fan mounted behind the condenser and adapted to the condenser. A driving device for driving the fan is also mounted on the frame 1, which is laterally offset from the longitudinal symmetry plane of the condenser by a distance. By using the above method to set up the driving device, there is enough space on one side of the driving device near the longitudinal symmetry plane of the condenser to place some other components of the oil cooler. There is no need to set up an additional frame on frame 1 for placing other components of the oil cooler, making frame 1 structurally simple and easy to process. The entire structure of the oil cooler is simple, compact, small in volume, and easy to transport and install.
