Blind window opened and closed through temperature control and engine compartment structure

Abstract

The invention discloses a blind window opened and closed through temperature control and an engine compartment structure.The blind window opened and closed through temperature control comprises a blind window body and is characterized by further comprising a temperature control device for controlling the opening angle of the blind window body, the temperature control device comprises a rotating mechanism connected with the blind window body, the rotating mechanism is provided with a cross bar, one end of the cross bar is provided with a rotatable first paraffin tube, the other end of the cross bar is provided with a rotatable second paraffin tube, the first paraffin tube and the second paraffin tube are located at the two sides of the cross bar respectively, the first paraffin tube is provided with a piston ball bar in contact with the cross bar, the second paraffin tube is provided with a return spring in contact with the cross bar, and the temperature control device is further provided with an air inlet pipe and an air outlet pipe which are connected with pipelines of an intercooler respectively.The blind window can be opened or closed automatically according to the temperature, thereby it is guaranteed that the indoor temperature of an engine compartment is within the reasonable range, and therefore the overall efficiency can be improved.

Description

technical field [0001] The invention relates to a temperature-controlled shutter and an engine room structure. Background technique [0002] At present, most of the existing construction machinery products at home and abroad have difficulties in cold start and low work efficiency when operating in low temperature areas, or excessive heat dissipation under low load conditions, which affects the thermal efficiency of the engine. The temperature of the engine room of construction machinery operating in low-load areas is caused by low temperature: since the engine hoods of current construction machinery adopt a fixed structure with non-adjustable air inlet and outlet, when operating under low temperature or low load conditions, it will be caused by the temperature of the engine room and the temperature of the engine room. Excessive external heat exchange causes the performance of the engine itself to decline, thereby affecting the start-up and work efficiency of the whole machin...

Problems solved by technology

[0002] At present, most of the existing construction machinery products at home and abroad have difficulties in cold start and low work efficiency when operating in low temperature areas, or excessive heat dissipation under low load conditions, which affects the thermal efficiency of the engine. The temperature of the engine room of construction machinery operating in low-load areas is caused by low temperature: since the engine hoods of current construction machinery adopt a fixed structure with non-adjustable air inlet and outlet, when operating under low temperature or low load conditions, it will be caused by the temperature of the engine room and the temperature of the engine room. The external heat exchange is too fast, which leads to the decline of the working performance of the engine itself, thus affecting the start-up and working efficiency of the whole machine
