High-efficiency heat exchanger and method for processing heat exchanger membrane

Abstract

The invention discloses a high-efficiency heat exchanger and a method for processing a heat exchanger membrane. The heat exchanger comprises an upper chip and a lower chip, wherein the upper and lower chips are made of a membrane material through hot forming; a guide air inlet, a guide air inlet area, a core efficiency area, a guide air outlet area and a guide air outlet are formed in the upper and lower chips respectively; the guide air inlet and the guide air outlet are circular arc inlet and outlet; induction air grids are arranged in the guide air inlet area and the guide air outlet area; convex raised ridges, concave valleys and micro salient points are formed in the core efficiency area; the guide air inlet area, the core efficiency area and the guide air outlet area form an air duct in a shape like a Chinese character zhi; and baffles are arranged on two sides of the core efficiency area. The membrane material consists of a matrix and a filler, wherein the matrix is polypropylene; the filler comprises boron nitride and aluminum oxide, 0.4 weight percent of antioxidant is added into polypropylene particles, the boron nitride and aluminum oxide are mixed to form the filler according to a volume ratio of 5:2, and the matrix and the filler are mixed into aggregates according to a weight ratio of 65:35 and are subjected to hot forming.

Description

technical field [0001] The invention relates to a processing method of a heat exchanger (core body) and a membrane body of the heat exchanger, and is an energy-saving and environment-friendly air treatment device mainly used for improving and treating the air quality and heat recovery of the air-conditioning environment and the special environment of a machine room. Background technique [0002] Air treatment equipment is mainly used to improve air quality and heat recovery in air-conditioning environments and special environments in machine rooms. Its main structure includes motors, centrifugal fans, outer box shells, internal air duct structures, filters, heat exchangers, and controllers. Wait. The heat exchanger is to use the physical properties of heat conduction in the air replacement process, absorb the heat of the exhaust air, then transfer the heat to the fresh air, and send it back to the air-conditioning environment, reducing the energy consumption of the air-condi...

Problems solved by technology

The heat exchangers currently used generally have the following three problems: (1) paper film or aluminum foil is used as the film material of the heat exchanger, the heat conduction structure is planar conduction, the heat transfer area is small, and the heat transfer efficiency Relatively low; (2) The paper film is hygroscopic, and the aluminum foil is conductive, so that the heat exchanger itself is easy to conduct electricity, and there are adverse safety hazards such as conductive leakage during use; (3) The paper film material and aluminum foil material are absorbent and Easy to oxidize, easy to breed pathogenic bacteria and microorganisms
