Aforesaid type tube dustproof heat exchanger, the cross section of wherein said heat exchanger core body is radial, describedly radially include a core for heat exchanger core body, the outward extending heat exchange fin of axle core lateral wall, constitute the heat exchange cavity between heat exchange fin or adjacent heat exchange fin, be provided with through hole in the axle core, this through hole is the heat exchange cavity, heat exchange fin is wound with heat exchanger tube outward, and the heat exchanger tube after the winding is shape in the shape of a spiral.
Aforesaid type tube dustproof heat exchanger, the cross section of wherein said heat exchanger tube are circle, ellipse or polygon.
Aforesaid type tube dustproof heat exchanger, wherein the outer surface at heat exchanger core body is provided with the spiral heat exchange tube embedded groove, and the cross sectional shape of its cross sectional shape and heat exchanger tube matches, and heat exchanger tube is spirally wrapped around the outer surface of heat exchanger core body.
Advantage of the present utility model is that the version of heat exchanging device carried out completely improving, heat exchange cavity in the heat exchanger core body is the through hole of up/down perforation, eliminate the air flow blind angle, having heat exchange effect preferably and dust is difficult for assembling, the dustproof coating of setting up more can reduce adhering to of dust and be convenient to cleaning, thereby improve heat exchange efficiency simple in structure, volume compact of the present utility model, cleaning is convenient, has good anti-dust performance, good effect of heat exchange.
The purpose of this utility model, advantage and characteristics will illustrate and explain that these embodiment only provide as an example by the unrestricted explanation of following preferential embodiment.
