Self-cleaning heat exchanger with high ventilation effect

Abstract

The invention discloses a self-cleaning heat exchanger with a high ventilation effect, and belongs to the technical field of ventilation and heat exchange, the self-cleaning heat exchanger comprises an outer sleeve, a pipe sleeve mechanism is fixedly mounted in an inner cavity of the outer sleeve, a direction adjusting mechanism is arranged on one side of the outer sleeve, and a heat exchange mechanism is fixedly mounted on one side of the direction adjusting mechanism. According to the heat exchange device, heat exchange air is in contact with the surfaces of the fin components to achieve heat exchange of media in the heat exchange tubes, the air is blown on the surfaces of the fin components and then extends to the two sides of the surfaces of the fin components through the interaction of the spoilers, and after air flow penetrates through the surfaces of the fin components, vortexes are generated due to pressure changes of the rear sides of the fin components; on one hand, the air pressure vortex can prolong the air heat exchange staying time and effectively improve the heat exchange efficiency, and on the other hand, the staying vortex can perform particle capture through circulation on the surfaces of the dust collection plates, so that generation of dust on the outer walls of the fin components can be effectively reduced through the fin mechanisms and the dust collection plates which can be stacked, and the maintenance resistance is effectively improved.

Description

technical field [0001] The invention belongs to the technical field of ventilation and heat exchange, in particular to a self-cleaning heat exchanger with high ventilation effect. Background technique [0002] In order to control the temperature during ventilation, a heat exchanger is generally required to achieve heat exchange treatment for the flowing air. [0003] Chinese patent document CN101622512B discloses a heat exchanger consisting of the following components: a heat transfer tube (12); a plurality of heat transfer fins (13a), which are along a direction crossing the axis of the heat transfer tube (12) Arranged and arranged; and cut out standing pieces (14), which are arranged on the heat transfer surface of each heat transfer fin (13a). A slit extending along the longitudinal direction is provided at the upper end or the upper and lower ends of the cut-out standing piece (14). The incision guides the condensed water generated on the surface of the heat transfer f...
