Abstract

The invention relates to a main cooler assembly. The main cooler assembly is small in size and superior in performance so as to meet the requirement for the maximum temperature group T4 (< 135 DEG C) of an explosion-proof diesel forklift, under the designed use environmental temperature, the explosion-proof forklift and a common forklift can also continuously work, with a reasonably-designed air inlet channel and an air exhaust channel, power performance of an engine is not decreased, and the whole vehicle performance of the explosion-proof forklift is the same as that of the same type common forklift. According to the technical scheme, the main cooler assembly comprises a sealed shell body and an air exhaust heat exchange chamber arranged in the shell body, a gas is reserved between the shell body and the air exhaust heat exchange chamber, and cooling water is filled in the gap to form a water interlayer. The main cooler assembly is suitable for the explosion-proof diesel forklift with the high explosion-proof grade and other explosion-proof internal combustion engineering mechanical vehicles.

Description

technical field

[0001] The invention relates to a main cooler assembly, which is mainly suitable for explosion-proof internal combustion forklifts with high explosion-proof grades and other explosion-proof internal combustion engineering machinery vehicles. Background technique

[0002] In an explosion-proof internal combustion forklift used in a hazardous environment containing flammable gas or flammable dust or both, when the maximum surface temperature of the vehicle exceeds the minimum ignition temperature of the flammable gas mixture and flammable dust, it will adhere to the surface of the vehicle These flammable substances can be ignited. The design of explosion-proof forklifts should be able to ensure that the maximum surface temperature of the vehicle during normal use should not exceed the minimum ignition temperature of the flammable substances present in the place where the vehicle is used. to classify temperature groups. The highest temperature group of the for...
