a cooling device

Abstract

The invention discloses a heat dissipation device, comprising an output seat, a cavity is arranged inside the output seat, a pinch tube is plugged into the upper end of the output seat, a heat conduction component is clamped and installed in the output seat, the output seat The upper end of the seat is provided with an air outlet, the air outlet is located above the heat conduction assembly, and the air outlet communicates with the heat conduction assembly, the lower end of the heat conduction assembly is fixedly installed with a heat dissipation assembly, the heat conduction assembly communicates with the heat dissipation assembly, and the rotating The upper end of the shaft passes through the heat conduction assembly and the heat dissipation assembly and is located in the pinch tube. The lower end of the rotating shaft is fixedly equipped with a clutch cup. The clutch cup is provided with an air inlet hole, and the partition plate is provided with a vent hole. In the present invention, the heat conduction component is communicated with the heat dissipation component and the air outlet is connected with the heat conduction component to form an air duct, which achieves the effect of integrated heat dissipation, can dissipate heat quickly, and integrates it into the output shell, saving space and making it more convenient to carry .

Description

technical field [0001] The invention relates to the technical field of lawnmowers, in particular to a heat dissipation device. Background technique [0002] A lawn mower, also known as a weeder, lawnmower, lawn trimmer, etc., is a mechanical tool used to trim lawns and vegetation. There are many kinds of lawn mowers in the prior art, among them, the power transmission mode of a lawn mower is that the power output device is directly connected with the output shaft through the clutch, and the staff is grasped outside the output shaft when using it. The casing is used for mowing work, the cutterhead is installed on the walking wheel, the cutterhead is equipped with an engine, and the output shaft of the engine is equipped with a blade. The blade uses the high-speed rotation of the engine to increase the speed a lot, saving the working time of the weeding workers. , reducing a lot of human resources, lawn mowers are divided into hob type, rotary knife type, side-mounted type an...

Problems solved by technology

There are many kinds of lawn mowers in the prior art, among them, the power transmission mode of a lawn mower is that the power output device is directly connected with the output shaft through the clutch, and the staff is grasped outside the output shaft when using it. The casing is used for mowing work, the cutterhead is installed on the walking wheel, the cutterhead is equipped with an engine, and the output shaft of the engine is equipped with a blade. The blade uses the high-speed rotation of the engine to increase the speed a lot, saving the working time of the weeding workers. , reducing a lot of human resources, lawn mowers are divided into hob type, rotary knife type, side-mounted type and throwing knife type. In theory, using roughly the same engine to achieve the same function, the more complicated the structure, The more factors of failure, the more complex the piggyback structure, so it is easy to go wrong

The actual use is also true, the backpack is prone to problems

[0003] Judging from the actual situation, the domestic brush cutter market is basically a professional market, which is a durable machine. Therefore, the domestic market basically does not use the backpack type, and almost all of them are side-mounted. Most of the power output structures of lawn mowers are rigidly connected. When in use, the output plate of the engine will generate a lot of heat. If the heat is not dissipated, it may affect the life of the parts. Most of the existing lawn mowers are passive. Heat dissipation, it is difficult to dissipate the heat quickly, resulting in serious heat accumulation of the output shaft, which may cause danger in severe cases. Due to the small volume of the existing lawn mower output disc, it is difficult for other heat dissipation devices to dissipate heat, and ordinary The cooling device is inconvenient to carry, so we need to propose a cooling device
