Abstract
The invention discloses an assembly of an instrument rear cover and a liquid crystal support. The assembly comprises the instrument rear cover and the liquid crystal support. A first chip heat dissipation protrusion and a second chip heat dissipation protrusion are arranged in the middle of the inner wall of the instrument rear cover. Other areas on the outer wall of the instrument rear cover except a loudspeaker installing area and a notch are covered with a plurality of strip-shaped heat-dissipating fins. The heat-dissipating fins are parallel and are arranged in a left and right spaced mode. A copper pipe is welded to the inner wall of the instrument rear cover after being pressed flatly. The extending direction of the copper pipe is perpendicular to the extending direction of the heat-dissipating fins. The copper pipe at least penetrates through more than 80% of the heat-dissipating fins. The front, the left and the right of the liquid crystal area extend outwards respectively to form a front coaming, a left coaming and a right coaming. The front coaming, the left coaming and the right coaming are in crescent shapes. The front coaming is provided with a plurality of heat-dissipating fins extending front and back. The left coaming and the right coaming are provided with a plurality of heat-dissipating fins extending left and right. The assembly has good heat-dissipating performance and can prevent full-liquid-crystal instrument from halting at normal temperature.
