Long life highly effective energy-conserving type heat exchanging core

Abstract

The invention relates to an energy-saving type heat exchange core body with long service life and high efficiency. The core body is formed through overlaying a plurality of monomer heat exchange chips; each monomer heat exchange chip consists of a keel and a heat exchange membrane; and an air channel is divided into a new air channel and an air exhaust channel by the heat exchange membrane. The heat exchange core body is characterized in that the monomer heat exchange chip comprises four layers; the first layer is a heat exchange membrane 1, the second layer is a longitudinal keel; the third layer is a heat exchanger membrane 2; the fourth layer is a transverse keel; and the longitudinal keel and the transverse keel are separately disconnected and form a rectangular transverse air channel and a rectangular longitudinal air channel respectively. The heat exchange core body can be detached, maintained and cleaned, has long service life of the whole machine, even and full heat transfer and high thermal reclaiming efficiency, and can realize outsize wind amount of 50,000m<3>h.

Description

technical field [0001] The invention relates to a heat exchange core, which belongs to the core element of air treatment equipment. Background technique [0002] The fresh air total heat exchanger is an environmental protection and energy-saving equipment used to improve the air quality of public places and recover the exhaust energy of air conditioners. Its main components are the outer shell, heat exchange core and filter. The heat exchange core can use the exhaust air to Pre-cooling and drying the fresh air, preheating and humidifying the fresh air in winter, so that the fresh air load is significantly reduced, thereby saving the energy consumption of the cooling and heating system. The disadvantages of current full heat exchanger products are: first, because the fresh air duct and exhaust air duct in the core are in the form of vertical crossing, the heat transfer time is not sufficient, the heat transfer area is not large enough, and the heat transfer is not uniform eno...

AI Technical Summary

Problems solved by technology

The disadvantages of current full heat exchanger products are: first, because the fresh air duct and exhaust air duct in the core are in the form of vertical crossing, the heat transfer time is not sufficient, the heat transfer area is not large enough, and the heat transfer is not uniform enough, so the total heat exchange The heat recovery efficiency of heat exchanger products is generally low, generally between 45% and 55%, and the product quality is generally poor, which has a great negative impact on the market; Bonded with heat transfer paper film, the strength of the core is small, the air duct is narrow, the resistance of the air duct is large, the core is prone to moisture, collapse and deformation, and the maximum air volume can only reach 2000m 3 The / h model has a small application range; third, the paper core is made of paste, so it cannot be cleaned and maintained, and its service life is generally only 3 to 4 years, so the core needs to be replaced regularly, which is expensive
