Abstract

The invention discloses a heating element of a flameproof air heater. The heating element of the flameproof air heater comprises an installation seat, wherein an electrical heating tube set is arranged on the installation seat, a plurality of baffles are arranged on the electrical heating tube set, and adjacent baffles are arranged in a mutually parallel and staggered mode. The electrical heating tube set is provided with the baffles, the adjacent baffles are arranged in the mutually parallel and staggered mode so that fluid can make full contact with the electrical heating tube set, and the heat conduction efficiency is improved; in addition, a plurality of through holes are formed in the baffles, filter screens are arranged in the through holes, therefore, the flow velocity of the fluid can be improved, impurities in the fluid can be prevented from flowing out, the filter screens can play a role in filtration, and usage is more convenient.

Description

technical field [0001] The present invention relates to a heating element, more particularly to a heating element of an explosion-proof air heater. Background technique [0002] In production and life, there are many occasions that require hot air, such as material drying, warm air heating, medical disinfection, high-temperature air combustion, etc. The circulating electric heater mainly heats the fluid. The heater itself has its own container. The fluid medium is pressed into the container through a pump or other power through a pipeline. There is a diversion device inside the container to make the medium form convection. After heating, Out of the set outlet pipe. In the prior art, the electric heater includes a casing and a heating element, the heating element is arranged in the casing, the heating element includes a mounting seat, and the electric heating tube group is arranged on the mounting seat, the heating element of this structure, due to the fluid Insufficient co...
