Cooling system for horizontal diesel engine digital generation unit

Abstract

The invention relates to a cooling system of digit generating unit of horizontal diesel engine, wherein the wind frame, cylinder cover and the horizontal frame form the permanent-magnetic generator main cooling ventilate chamber; the upper and lower wind plates of cylinder are integrated with the horizontal frame; the upper and lower wind plates, the cylinder cover and the horizontal frame form the upper and lower main cooling ventilate chambers of cylinder; the side cover of frame and the back frame of sound absorber form the sub cooling cycle chamber of sound absorber; the invention uses permanent-magnetic generator main cooling ventilate chamber, upper and lower main cooling ventilate chambers, and the sub cooling cycle chamber of sound absorber to form the cooling system, with many combine surface, to stepped cool the heating unit effectively, with long service.

Description

technical field [0001] The invention relates to a cooling system of a digital generator unit of a horizontal diesel engine, in particular to a digital generator set of a horizontal diesel engine particularly suitable for forced air cooling, and belongs to the field of power generators. Background technique [0002] The forced air-cooled horizontal diesel engine digital power generation unit requires sufficient ambient temperature air to cool the cylinder, cylinder head, lubricating oil shell, permanent magnet generator, exhaust pipe and muffler of the horizontal diesel engine. Due to the high heat generation and high temperature of the above-mentioned parts, timely heat dissipation is required to ensure the good continuous operation and long service life of the digital power generation unit of the horizontal diesel engine. [0003] Before the present invention was made, in the prior art, the diesel engine cooling device inside the forced air-cooled diesel power generation un...

Problems solved by technology

[0003] Before the present invention was made, in the prior art, the diesel engine cooling device inside the forced air-cooled diesel power generation unit usually used a cylinder-enclosed cooling ventilation cavity, that is, the cylinder of the diesel engine was surrounded by an air guide cover and an air-inducing plate, and the air was sucked by a fan. The incoming cooling air cools the cylinder, while natural air cooling is generally used for the cooling of the lubricating oil shell of the diesel engine and the muffler, and the muffler is sometimes wrapped with thermal insulation material for heat insulation; Timely and efficient cooling of parts with high heat generation outside the cylinder (such as the oil shell at the bottom of the diesel engine, the exhaust pipe of the diesel engine, and the muffler, etc.)
