Counter-flow heat exchange core body for fresh air ventilator

A technology of counter-flow heat exchange and fresh air ventilator, which is applied in the direction of heat exchanger, heat exchanger type, heat exchanger shell, etc., can solve the problem that the effect of cross-flow heat exchange is not as good as that of counter-flow, restricting the development of fresh air ventilator and Popularization, increase in resistance pressure drop, etc., achieve the effect of reducing weight and cost, simple structure, and reducing resistance pressure drop

Problems solved by technology

[0002] Most of the fresh air ventilators in the market currently use plate-fin cross-flow heat exchange cores with corrugated plate support structures. The corrugated plate support can solve the support problem of the heat exchange plate, but it is followed by an increase in resistance pressure drop , the effect of cross-flow heat exchange is far inferior to that of counter-flow. In addition, the volume of the fresh air ventilator is directly limited by the diagonal length of the core, so this type of heat exchange core has low heat exchange efficiency, large volume, and large resistance pressure drop. problems, thus limiting the development and popularization of fresh air ventilators

Embodiment Construction

[0027] Below in conjunction with accompanying drawing, the present invention is further described:

[0028] A counter-flow heat exchange core body for a fresh air ventilator, which is composed of a top plate 1, a bottom plate 5 and 2-500 heat exchange units of the same shape. The heat exchange unit is composed of a heat exchange diaphragm 3, an end seal 4 and two The root and side seals are composed of 2. The end seal is arranged on the upper surface of one end of the heat exchange diaphragm, and one end of the side seal is flush with the other end of the heat exchange diaphragm and is arranged on the upper surface of the side of the heat exchange diaphragm. The length of the seal is 9 / 10-1 / 2 of the side length of the heat exchange membrane. The heat exchange membrane is composed of a full heat exchange paper 3-1 and a support frame with holes 3-2. The adjacent heat exchange units Stacked at 180 degrees and fixedly connected, the top plate is fixedly set above the uppermost he...

Abstract

A counterflow heat exchange core body for a fresh air exchanger is composed of a top plate (1), a bottom plate (5) and 2-500 heat exchange units which have the same shape. The heat exchange unit is composed of a heat exchange membrane (3), an end seal strip (4) and two lateral seal strips (2). The end seal strip (4) is arranged on the upper surface of one end edge of the heat exchange membrane (3). The lateral seal strip (2) is arranged on the upper surface of the lateral edge of the heat exchange membrane (3) with one end thereof aligned with the other end of the heat exchange membrane (3). The length of the lateral seal strip (2) is 9 / 10-1 / 2 of the length of the lateral side of the heat exchange membrane (3). The adjacent upper and lower heat exchange units are overlapped at an angle of 180 degrees and connected fixedly. The top plate (1) is fixed on the top heat exchange unit and the bottom plate (5) is fixed under the bottom heat exchange unit.

Description

technical field [0001] The invention relates to a heat exchange core body, in particular to a counterflow heat exchange core body for a fresh air ventilator. technical background [0002] At present, the fresh air ventilators in the market mostly use the plate-fin cross-flow heat exchange core with corrugated plate support structure. The corrugated plate support can solve the support problem of the heat exchange plate, but it is followed by an increase in resistance pressure drop , the effect of cross-flow heat exchange is far inferior to that of counter-flow. In addition, the volume of the fresh air ventilator is directly limited by the length of the diagonal of the core, so this type of heat exchange core has low heat exchange efficiency, large volume, and large resistance pressure drop. problem, thereby limiting the development and popularization of the fresh air ventilator. Contents of the invention [0003] The purpose of the present invention is to overcome the defi...
