Abstract

A bulldozer engine cover, comprising a flat top cover, a left side cover and a right side cover, the left and right sides of the flat top cover are respectively connected to the tops of the left side cover and the right side cover, and both the left side cover and the right side cover are lower It is installed on the flat top cover, and there is a cooling hole on the flat top cover. A cooling fan is installed in the cooling hole. The cooling fan is connected to the power circuit after passing through the controller. The controller is installed near the junction of the flat top cover and the left side cover , the power supply is set at the end of the left cover away from the controller; the controller includes a metal shell, an input power line, an output power line, a power supply sheet, an insulating column, an insulating table, a temperature sensing sheet, a left conductive column, and a right conductive column . This design not only has high heat dissipation efficiency, but also has strong controllability.

Description

technical field [0001] The invention relates to an engine device, in particular to a bulldozer engine cover, which is particularly suitable for improving heat dissipation efficiency and enhancing controllability. Background technique [0002] At present, the engine covers of existing motor vehicles, such as cars, passenger cars or special vehicles, are basically closed structures, lacking heat dissipation design, and the heat generated by the engine needs to be dissipated through the heat dissipation vents on the front of the vehicle, and the heat dissipation effect is relatively poor. [0003] Chinese patent, the authorized announcement number is CN202439763Y, and the authorized announcement date is September 19, 2012. The utility model patent discloses an engine cover plate with good heat dissipation performance, including the cover plate body, and a ventilation system is provided on the cover plate body. Holes, a heat dissipation ventilation hood is provided on the ventil...
