Abstract

The invention discloses an air heater of a diesel engine. The air heater comprises a shell component and a heating body component, wherein the shell component is a frame having a center cavity, and comprises a mounting basal plate and a shell skeleton; one end of the shell skeleton is fixed on the mounting basal plate; the shell skeleton is manufactured by a heat resistant material; the heating body component is fixed in the center cavity of the shell component; the shell skeleton and the heating body component are both inserted into an air inlet pipe through an opening of the air inlet pipe; and the mounting basal plate is fixed outside the air inlet pipe, and closes the opening of the air inlet pipe. The mounting basal plate of the air heater is arranged outside the air inlet pipe, and the high-melting-point shell skeleton is arranged in the air inlet pipe, so that the fusion phenomenon caused by overhigh temperature of the shell component of the heater is solved.

Description

technical field [0001] The invention relates to a heater, in particular to a drawer-type air heater for diesel engine preheating, in which a heating element is inserted through the side wall of an intake pipe. Background technique [0002] The shell of the existing drawer-type heater is an aluminum die-casting one-piece shell. Since the melting point of die-casting aluminum is low (510°C-580°C), the shell for fixing the heating element bracket is located inside the intake pipe, and is subject to Due to the limitation of heat dissipation conditions, the surface temperature of the shell is high. When the temperature is close to the melting point of the shell, thermal deformation of the shell will occur. As the temperature continues to rise, the shell will eventually melt into the engine block and damage the engine block. The cylinder block is damaged. Furthermore, in the existing air heaters, the heating body adopts the shape of round wire or flat wire, which is bent into a s...
