Description

Technical Field

[0001] The utility model belongs to the technical field related to oil coolers, and in particular relates to a plate-fin oil cooler with high-efficiency heat dissipation. Background Art

[0002] Plate-fin oil coolers are highly efficient heat exchange devices that increase the heat transfer area through a combination of plates and fins, thereby improving cooling efficiency. They are widely used in various industrial fields and mechanical equipment, such as engine cooling systems and hydraulic systems. They usually consist of two fluid channels, one for the heat medium (such as oil) and the other for the cooling medium (such as air or water). The two flow into each other to achieve heat transfer. However, in actual use, they still have the following disadvantages:

[0003] When the plate-fin oil cooler is working, it directly cools the oil passing through it through a medium. However, when the oil passes through, the oil directly exchanges heat with the air or water, and the cooling efficiency of the oil is low, and the heat dissipation efficiency is not high enough;

[0004] When the plate-fin oil cooler is working, after the oil in it dissipates heat, it is concentrated through a centralized box and then discharged to the equipment in use. However, during the cooling process of the oil in the cooler, the cooling effect of the oil at different positions is different, and the output oil temperature is uneven, which affects the use effect of the oil. Utility Model Content

[0005] The purpose of the utility model is to provide a plate-fin oil cooler with efficient heat dissipation. By arranging an oil delivery component, a fixing box, an external fixing frame and a drive motor, the utility model solves the problems of insufficient heat dissipation efficiency and uneven output oil temperature of the plate-fin oil cooler during operation.

[0006] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0007] The utility model is a plate-fin oil cooler with high heat dissipation, comprising an oil delivery component, a fixed box, an external fixed frame and a drive motor. The oil delivery component comprises two oil delivery chambers, the two oil delivery chambers corresponding to each other above, an oil delivery flat pipe fixedly connected to each other at equal distances between the two oil delivery chambers, a fixed box fixed between the two oil delivery chambers, a heat dissipation frame fixedly passed through the oil delivery flat pipes in the fixed box, an external fixed frame fixed to the front side of the two oil delivery chambers and the fixed chamber, a drive motor fixed to one side of the oil delivery chamber below, when working, the oil is transported through the fixed box by the oil delivery component, and the oil is transferred through the oil delivery flat pipe so that the oil passes through the oil delivery component and the fixed box, and exchanges heat with the water in the fixed box when passing through the oil delivery component, a heat dissipation fan is connected thereto through the external fixed pipe, and the rotating block is driven to rotate by the drive motor.

[0008] Furthermore, the oil delivery component also includes an oil inlet pipe and an oil outlet pipe. The oil inlet pipe is fixedly connected to the center of the top of the oil delivery cavity, and the oil outlet pipe is fixedly connected to the bottom of the oil delivery cavity. The oil delivery component delivers oil to the oil delivery cavity through the oil inlet pipe and outputs the oil after heat dissipation through the oil outlet pipe.

[0009] Furthermore, a plurality of heat dissipation fins are evenly fixed and connected in each heat dissipation frame, and the heat dissipation fins in the same heat dissipation frame are parallel to each other. The heat dissipation frame increases the heat dissipation area through the heat dissipation fins to discharge the heat.

[0010] Furthermore, a fixing bracket is fixed to the front of the inner wall of the outer fixing frame, a heat dissipation fan is fixed through the fixing bracket, the outer fixing frame fixes the heat dissipation fan through the fixing bracket, and air is drawn into the outer fixing frame through the heat dissipation fan and transported to the heat dissipation frame.

[0011] Furthermore, a driving shaft is fixed to the output end of the driving motor, and the driving shaft is movably connected to one end of the oil delivery cavity located below. When the driving motor is working, the driving shaft drives the rotating block to rotate.

[0012] Furthermore, a rotating block is fixed to one end of the drive shaft away from the drive motor, and stirring blades are fixed to the circumference of the rotating block in a circular array. The rotating block and the stirring blades are both arranged in the oil delivery cavity, so that when the stirring blades rotate, the oil in the oil delivery cavity below is driven to be fully mixed.

[0013] The utility model has the following beneficial effects:

[0014] The utility model solves the problem that the heat dissipation efficiency of the plate-fin oil cooler is not high enough when it is working by arranging an oil delivery component, a fixing box and an external fixing frame. When dissipating heat, when the oil passes through the oil delivery flat pipe, the heat dissipation fan is started, and the heat dissipation fan draws air from the outside into the external fixing frame, and then transports it to the heat dissipation frame, and then discharges it after the heat is dissipated by the heat dissipation fins in the heat dissipation frame, so that the water in the fixing box dissipates heat quickly, and the temperature of the water is smaller after absorbing the heat by transferring heat through the water. When dissipating heat, the heat is transferred faster than the oil, thereby increasing the efficiency of oil cooling.

[0015] The utility model solves the problem of uneven temperature of the oil output by the plate-fin oil cooler by providing an oil delivery component and a drive motor. When the drive motor is working, it drives the drive shaft to rotate. When the drive shaft is driven to rotate, it drives the rotating block to rotate. The rotation of the rotating block drives the stirring blade to rotate. When the stirring blade rotates, the oil in the oil delivery chamber below is fully mixed, so that the temperature of the oil in the oil delivery chamber below is more uniform when it is output.

[0024] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Specific embodiment 1

[0025] See also Figure 1-4The utility model is a plate-fin oil cooler with high heat dissipation, comprising an oil delivery component 1, a fixed box 2, an outer fixed frame 3 and a drive motor 4. The oil delivery component 1 comprises two oil delivery chambers 101, which correspond to each other up and down. When the oil delivery component 1 is working, the oil that needs to be dissipated passes through the fixed box 2 and is centrally delivered to the oil delivery flat pipe 104 through the oil delivery chamber 101. The two oil delivery chambers 101 are equidistantly connected to each other with an oil delivery flat pipe 104. The oil is delivered to the fixed box 2 through the oil delivery flat pipe 104 and is separated from the water in the fixed box 2. The fixed box 2 is fixed between the two oil delivery chambers 101. When working, the fixed box 2 is fixed to the oil delivery chamber 101. The box 2 is filled with water, so that the oil delivery flat pipe 104 is immersed in the water. When the oil passes through, it exchanges heat with the water and dissipates heat. A heat dissipation frame 201 is fixed between the oil delivery flat pipes 104 in the fixed box 2. Air can pass through the heat dissipation frame 201. When the air passes through the heat dissipation frame 201, the water in the fixed box 2 is cooled. The two oil delivery chambers 101 and the front side of the fixed chamber are jointly fixed with an external fixed frame 3. The heat dissipation fan 302 is connected to it through the external fixed frame 3. A drive motor 4 is fixed on one side of the lower oil delivery chamber 101. The drive motor 4 drives the stirring blade 403 to rotate, so that the temperature of the oil in the lower oil delivery chamber 101 becomes uniform.

[0026] Specifically, the oil delivery component 1 also includes an oil inlet pipe 102 and an oil outlet pipe 103. The oil inlet pipe 102 is fixedly connected to the center of the top of the upper oil delivery chamber 101, and the oil outlet pipe 103 is fixedly connected to the bottom of the lower oil delivery chamber 101. When the oil delivery component 1 is working, the oil inlet pipe 102 is connected to the pipeline for delivering oil, so that the oil is delivered to the upper oil delivery chamber 101, and the oil outlet pipe 103 is connected to the pipeline for delivering cooled oil, so that the oil is output from the lower oil delivery chamber 101 to the pipeline for delivering cooled oil.

[0027] Furthermore, each heat dissipation frame 201 is evenly fixed with a number of heat dissipation fins 202, and the heat dissipation fins 202 in the same heat dissipation frame 201 are parallel to each other. When the heat dissipation frame 201 is working, the heat dissipation efficiency of the heat dissipation frame 201 to the water in the fixed box 2 is accelerated when the air passes through the heat dissipation frame 201 through the heat dissipation fins 202.

[0028] Furthermore, a fixing bracket 301 is fixed to the front of the inner wall of the outer fixing frame 3, and a heat dissipation fan 302 is fixed through the fixing bracket 301. The outer fixing frame 3 is connected to the heat dissipation fan 302 through the fixing bracket 301, and the heat dissipation fan 302 draws air from the outside and then transports it to the heat dissipation frame 201.

[0029] The operating process of this embodiment is as follows: during operation, the oil is transported to the oil delivery chamber 101 through the oil inlet pipe 102, and then transported to the oil delivery flat pipe 104 through the oil delivery chamber 101, and then transported to the oil delivery chamber 101 located below through the oil delivery flat pipe 104, and then output to the oil outlet pipe 103 through the oil delivery chamber 101. When the oil passes through the oil delivery flat pipe 104, it exchanges heat with the water in the fixed box 2, so that the oil is cooled. When the oil passes through the oil delivery flat pipe 104, the heat dissipation fan 302 is started, and air is drawn from the outside into the outer fixed frame 3 through the heat dissipation fan 302, and then transported to the heat dissipation frame 201, and then discharged after the heat is dissipated by the heat dissipation fins 202 in the heat dissipation frame 201, so that the water in the fixed box 2 dissipates heat quickly. Heat is transferred by water, and the temperature change of water is smaller after absorbing heat. When dissipating heat, the heat is transferred faster than the oil, thereby increasing the efficiency of oil cooling. Specific embodiment 2

[0030] See also Figure 1 、 2 5. Based on the specific embodiment 1, a driving shaft 401 is fixed to the output end of the driving motor 4. The driving shaft 401 is movably connected to one end of the oil delivery chamber 101 located below. When the driving motor 4 is working, the driving shaft 401 is driven to rotate.

[0031] Specifically, a rotating block 402 is fixed to one end of the driving shaft 401 away from the driving motor 4, and stirring blades 403 are fixed to the circumference of the rotating block 402 in a circular array. The rotating block 402 and the stirring blades 403 are both arranged in the oil delivery chamber 101. When the driving shaft 401 is driven to rotate, the rotating block 402 is driven to rotate, and the rotation of the rotating block 402 drives the stirring blades 403 to rotate. When the stirring blades 403 rotate, the oil in the oil delivery chamber 101 below is fully mixed, so that the temperature of the oil in the oil delivery chamber 101 below is more uniform when it is output.

[0032] The operation process of this embodiment is as follows: when the drive motor 4 is working, the drive shaft 401 is driven to rotate. When the drive shaft 401 is driven to rotate, the rotating block 402 is driven to rotate. Through the rotation of the rotating block 402, the stirring blade 403 is driven to rotate. When the stirring blade 403 rotates, the oil in the oil delivery chamber 101 below is fully mixed, so that the temperature of the oil in the oil delivery chamber 101 below is more uniform when it is output.
