Hydraulic oil cooler

Abstract

A hydraulic oil radiator comprises a core and two oil tanks located on the outer sides of the core. The core consists of two main plates, two side plates, a plurality of heat dissipation pipes, and several inner and outer fins. The two main plates have several perforated slots. The two side plates are located between the two ends of the main plates and are perpendicular to the main plates. The heat dissipation pipes are located between the two main plates and are parallel to the side plates. A flat tube is formed by the upper and lower fitting of a first shaped frame plate with a first connecting part and a fitting end, and a second shaped frame plate with a second connecting part and a flexible abutment, which fits into the perforated slots of the main plates. The inner fins are correspondingly located inside each heat dissipation pipe, and their two ends are supported by the fitting section and the flexible abutment of the second shaped frame plate to form a positioning, thus forming a first fluid flow channel with the heat dissipation pipe. The hollow space between the two side plates is used to accommodate the outer fins, forming a second fluid flow channel, thereby allowing the opposite side of the outer fins to flow with a fan. The module is designed so that when the heated hydraulic oil flows through the first fluid flow channel of the radiator body to dissipate the oil temperature, the fan module starts to draw in cold air through the second fluid flow channel for heat exchange and carries out hot air, so that the hydraulic oil is cooled and sent to the oil tank, forming an oil circuit for heat dissipation. The first and second shaping frame plates of the heat dissipation pipe are connected to reinforce the weakest side of the heat dissipation pipe, thus thickening the heat dissipation pipe. Aluminum strips can be inserted according to customized needs to meet various requirements for the pressure resistance of the radiator. It can also effectively reduce the thickness of the upper and lower edge of the heat dissipation pipe, thereby increasing the heat dissipation efficiency. At the same time, due to the improvement of the heat dissipation oil pipe, it can be assembled by punching holes in the main board, replacing the short sealing strip of the conventional thick core material. This allows for a thinner and more flexible main board design, effectively improving assembly efficiency and significantly reducing material and welding costs.

Claims

A hydraulic oil radiator, comprising a core body and two hydraulic oil tanks, the two hydraulic oil tanks being respectively disposed on two sides of the core body, with an oil inlet and an oil outlet respectively disposed at the top of the oil tanks facing each other. The core body includes two main plates, two side plates, a plurality of heat dissipation pipes, and several inner and outer fins. Side plates perpendicular to the main plates are disposed between both ends of the two main plates. The plurality of heat dissipation pipes are disposed between the two main plates and parallel to each other with respect to the side plates. Inner fins are disposed inside the heat dissipation pipes, forming a first fluid flow channel with the heat dissipation pipes. Outer fins are arranged between adjacent heat dissipation pipes spaced apart. The space, with its two ends resting against the inner surface of the motherboard, forms a second fluid flow channel. This allows a fan module to be installed on the opposite sides of the outer fins of the hydraulic oil cooler, connecting the hydraulic oil cooler to the oil tank circuit. When the hydraulic oil tank receives heated hydraulic oil, it flows through the first fluid flow channel of the core for heat dissipation. Simultaneously, the fan module starts, drawing in cool air through the second fluid flow channel for heat exchange and carrying away hot air.

By using the first and second shaping frames of the heat pipe to thicken and strengthen the thickness on both sides of the heat pipe through the joint of the two frame plates, the forming thickness of the heat pipe can be effectively reduced. The main board can be thinned and bent to form a fixing plate for punching and assembly, which can effectively improve the assembly efficiency.
