Description

Technical Field

[0001] The utility model relates to the technical field of engine heat dissipation, in particular to a heat dissipation device for a passenger car engine compartment. Background Art

[0002] The engine compartment of a rear coach is generally an irregular space. The low heat dissipation efficiency of the engine compartment makes it difficult for the hot air to be discharged smoothly. The hot air gathers in the engine compartment, causing the cabin temperature to remain high. As a result, the engine body temperature is easily too high, making it impossible for the coach to run normally. In severe cases, it may cause circuit failure and cause a fire.

[0003] The existing Chinese patent with publication number CN214565682U discloses a heat dissipation structure for a bus engine compartment, including a general assembly frame, an engine is fixedly installed in the general assembly frame, a heat dissipation component is arranged at one end of the general assembly frame, the heat dissipation component includes a heat dissipation frame, and a plurality of fans are arranged on the heat dissipation frame. By arranging a plurality of fans on the heat dissipation frame at one end of the general assembly frame, the hot air in the bus engine compartment can be effectively evacuated, the temperature in the bus engine compartment can be reduced, and the temperature of the engine working environment can be reduced. A filter is arranged on one side of the fan, and limit blocks are symmetrically arranged on both sides of the filter. A dust brush is slidably arranged on the limit block. A filter is arranged on one side of the fan to ensure that the fan will not absorb large dust and impurities during the process of evacuating the air in the engine compartment, thereby ensuring the stability of the fan operation. A dust brush is arranged on one side of the filter, and dust and impurities on the surface of the filter can be brushed off by the dust brush. The structure is simple and easy to operate. The device uses a traditional fan to dissipate heat from the engine compartment. If the outside temperature is relatively high in summer, the cooling effect of the fan on the engine compartment will deteriorate as the temperature rises, and the fan itself will also generate heat when working. In summary, the cooling effect of the device is unstable, thereby reducing its practicality. Utility Model Content
