Engine cooling bottom cover plate and method, and excavator

Abstract

The invention relates to an engine heat dissipation base cover plate and a method as well as an excavator. The heat dissipation base cover plate comprises a base cover plate provided with a plurality of through holes, a temperature sensor connected with an engine, a controller connected with the temperatures sensor and an actuator for opening the through holes; the through holes are enclosed without external force; the temperature sensor is used for sending a temperature signal of the engine in real time to the controller; the controller is also used for controlling the opening of the through holes and sends a start command to the actuator according to the received signal; the actuator opens the through holes according to the command; and air flows are exhausted synchronously through an air ventilation port and the through holes. The engine heat dissipation base cover plate provided by the invention has the beneficial effects that the heat dissipation efficiency and the heat dissipation effect of the engine are improved; the fault problem of the engine and other components caused by long-time high temperature is prevented; the safety of the engine and the heat dissipation device thereof is improved; and the effectiveness of the heat dissipation operation of the engine is ensured.

Description

technical field [0001] The invention relates to an engine heat dissipation device of an excavator, in particular to an engine heat dissipation bottom cover plate and method and the excavator. Background technique [0002] An excavator is an earth-moving machine that uses a bucket to excavate materials higher or lower than the bearing surface, and loads them into transport vehicles or unloads them to the stockyard. Therefore, the engine of the excavator often works at a high It is easy to cause engine overheating and lead to engine failure; and the existing engine heat dissipation methods and devices usually set up exhaust holes on the top cover, and then form an air flow around the engine through the radiator and / or fan to cool the engine, and at the same time the air flow It is exhausted from the exhaust hole on the top cover; however, when the ambient temperature of the excavator's workplace is too high, the existing heat dissipation methods and devices often cannot smooth...
