Guide plate film type total-heat heat exchange core body for fresh air ventilator

Abstract

The invention provides a guide plate film type total-heat heat exchange core body for a fresh air ventilator. The guide plate film type total-heat heat exchange core body comprises a top plate, a bottom plate, and heat exchange units. Each heat exchange unit is composed of a heat exchange composite film, a supporting frame, an airflow baffle and a guide plate, wherein each heat exchange composite film and each supporting frame are fixedly connected for forming a bottom surface of each supporting frame. Each supporting frame is provided with an air inlet and an air outlet, and each airflow baffle perpendicular to each heat exchange composite film is arranged on each air inlet or each air outlet. Each guide plate is vertically arranged on the surface of the each heat exchange composite film for forming a heat exchange channel, two ends of each heat exchange channel are connected with an air inlet channel or an air outlet channel through a reducing and increasing pipe, and communication between each air inlet and each air outlet can be achieved. At least two heat exchange units are arranged between the top plate and the bottom plate in a stacking mode, air inlets and air outlets of two adjacent heat exchange units are opposite in position, and the air inlets and the air outlets of two alternating heat exchange units are identical in position. The guide plate film type total-heat heat exchange core body is excellent in heat and mass transfer property, high in heat transfer efficiency, small in resistance loss and size, low in cost and convenient to apply.

Description

technical field [0001] The invention relates to a guide plate membrane type total heat heat exchange core body for a fresh air ventilator. The invention belongs to the technical field of heat exchange equipment preparation. technical background [0002] At present, the vast majority of fresh air ventilators use plate-fin cross-flow heat exchange cores supported by corrugated plates. Although corrugated plates can better solve the problem of supporting heat exchange plates and can extend the heat exchange time limitedly, However, the contradiction of increased pressure loss cannot be reconciled. In addition, the heat exchange effect of the cross flow form is far inferior to that of the counter flow form, and the traditional paper material also limits the improvement of the efficiency of the heat exchange core. Not only that, the air flow also has a certain degree of interactive turbulence. Therefore, this type of heat exchange core has problems such as low heat exchange effi...

Problems solved by technology

[0002] At present, the vast majority of fresh air ventilators use plate-fin cross-flow heat exchange cores supported by corrugated plates. Although corrugated plates can better solve the problem of supporting heat exchange plates and can extend the heat exchange time limitedly, However, the contradiction of increased pressure loss cannot be reconciled. In addition, the heat exchange effect of the cross flow form is far inferior to that of the counter flow form, and the traditional paper material also limits the improvement of the efficiency of the heat exchange core. Not only that, the air flow also has a certain degree of interactive turbulence. Therefore, this type of heat exchange core has problems such as low heat exchange efficiency, large resistance pressure drop, large volume, heavy weight, difficult maintenance, cross-contamination, etc., which limits the development and popularization of fresh air ventilators
