Homogeneous heating device for heating air by means of graphene heating films

Abstract

The invention discloses a homogeneous heating device for heating air by means of graphene heating films. The device comprises a device box body and a box cover plate detachably and hermetically mounted on the outer wall of the device box body, an air inlet pipe and an air outlet pipe are respectively mounted on two end surfaces of the device box body, and an air filtering device is mounted on theair inlet pipe. An upper partition plate and a lower partition plate are installed on the inner wall of the device box body in parallel and divide the interior of the device box body into an upper part, a middle part and a lower part. The upper part and the lower part are driving chambers, the middle part is a heat exchange chamber, and the multiple graphene heating films are horizontally installed on the inner wall of the heat exchange chamber and electrically connected through wires. The homogeneous heating device for heating the air by means of the graphene heating films has the beneficialeffects that homogeneous hot air can be continuously generated, the temperature stratification phenomenon is avoided, the use requirements of places with high air temperature requirements are effectively met, and the practicability is good.

Description

technical field [0001] The invention relates to the field of graphene heating films, in particular to a homogeneous heating device that relies on graphene heating films to heat air. Background technique [0002] At present, the common air heating devices on the market generally use electric heating wires to generate heat and exchange heat with the air. Inhomogeneous heat, the air temperature closer to the electric heating wire is higher, and the air temperature farther away from the electric heating wire is lower. In addition, the air velocity in the air heating device is fast, and it is difficult to fully separate the high temperature air and low temperature air. Heat exchange, therefore, the temperature of the hot air coming out of the air heating device is not uniform, and there are obvious low temperature areas and high temperature areas, which is obviously not suitable for those places that require high air temperature. [0003] Although the Chinese patent application ...
