[0002] The engine is the core part of the bulldozer transmission system and provides power for the operation of the transmission system. At present, a large amount of heat is generated when the engine is used. In order to prevent its temperature from being too high, resulting in increased oil consumption, oxidation and deterioration, etc., a corresponding oil radiator is set at the windward side of the front grille of the bulldozer to introduce the oil into the radiator and cool the oil by air cooling. The surface of the existing oil radiator is provided with multiple sets of cooling fins. After long-term use, dust is easily accumulated on the cooling fins, affecting the cooling effect. Therefore, it is necessary to disassemble and clean it regularly. The existing cooling fins are usually fixedly installed on the surface of the radiator, and the radiator body needs to be disassembled and assembled, and a series of operations such as draining the oil are required, which is relatively troublesome. Therefore, a heat dissipation device for the bulldozer transmission system is proposed. Utility Model Content

[0019] The following is combined with Figure 1-5 This application is described in further detail.

[0020] An embodiment of the present application discloses a heat dissipation device for a bulldozer transmission system, including a first channel 1 and a second channel 2. The first channel 1 is provided with two groups, and a plurality of groups of second channels 2 are connected through the two groups of first channels 1. Integrated heat sinks 6 are provided between the second channels 2, and the integrated heat sinks 6 are connected by connecting plates 8. An installation mechanism is provided between the connecting plates 8 and the first channel 1, so that the integrated heat sinks 6 can be stably installed on the surface of the second channel 2.

[0021] Furthermore, the material ports of the first channels 1 are connected to the delivery pipes 5 via flanges, and the other ends of the delivery pipes 5 are connected to the engine via flanges.

[0022] Furthermore, two groups of connecting plates 8 are provided, and the two groups of connecting plates 8 are located on both sides of the integrated heat sink 6 .

[0023] Furthermore, the mounting mechanisms include a positioning plate 7 fixedly mounted on the first channel 1, a plurality of positioning rods 10 are inserted on the connecting plate 8, the positioning rods 10 are horizontally arranged, and one end of the positioning rods 10 is commonly fixedly connected to a movable plate 9, a spring 14 is sleeved on the positioning rods 10, and positioning holes 13 corresponding to the positioning rods 10 are opened on the surface of the positioning plate 7, and the positioning rods 10 can be moved into or out of the positioning holes 13.

[0024] Furthermore, a slide plate 11 is fixedly connected to the upper end of the movable plate 9, and a slide groove 12 adapted to the slide plate 11 is opened on the integrated heat sink 6 above. The slide plate 11 is installed in the slide groove 12 and forms a horizontal moving pair in the slide groove 12.

[0025] In this embodiment, the first channel 1, the second channel 2 and the integrated heat sink 6 constitute a heat dissipation device. The oil in the bulldozer engine can enter the first channel 1 and the second channel 2 through a delivery pipe 5 on one side. At this time, the wind volume when the bulldozer is driving is utilized, and then the oil is circulated and cooled through the integrated heat sink. The oil with reduced temperature then flows back to the engine through the first channel 1 and the delivery pipe 5 on the other side.

[0026] It should be noted that a corresponding oil pump and thermostat should be set up for use together. The thermostat sets the opening temperature of the valve, and the oil pump provides power for the engine oil, so that the engine oil flows into the cooling device to start a circulation and only needs to dissipate heat.

[0027] In this embodiment, the integrated heat sink 6 is assembled and connected with the second channel 2 through the installation mechanism. When the integrated heat sink 6 needs to be cleaned, the two sets of slide plates 11 are moved closer to each other along the slide groove 12, thereby driving the two sets of movable plates 9 to move, so that the positioning rod 10 is moved out of the positioning hole 13, and the restriction on the integrated heat sink 6 is released, so that the integrated heat sink 6 can be disassembled and cleaned; when the integrated heat sink 6 needs to be installed, it is only necessary to install the integrated heat sink 6 in reverse according to the above disassembly steps. In addition, the spring 14 can stably insert the positioning rod 10 into the positioning hole 13.

[0028] Furthermore, a fixing plate 3 is installed on one side of the first channel 1 , and the fixing plate 3 is installed on the bulldozer frame by setting fixing bolts 4 .
