Parallel flow warm-air core body

Abstract

The invention discloses a parallel flow warm-air core body, which belongs to the field of air conditioners and is especially suitable for air conditioners for engineering trucks. The parallel flow warm-air core body comprises a left water chamber and a right water chamber, wherein the left water chamber and the right water chamber are formed in parallel; a plurality of oblate tubes are connected between the left water chamber and the right water chamber; two ends of each oblate tube are inserted in through holes formed in the left water chamber and the right water chamber so as to lead the left water chamber to be communicated with the right water chamber; heat exchanging fins are arranged between the oblate tubes; and the parallel flow warm-air core body is characterized in that an upper protecting sheet and a lower protecting sheet are respectively arranged between the two ends of the left water chamber and the two ends of the right water chamber, the heat exchanging fins are corrugated fins, and the oblate tubes are porous oblate tubes provided with at least three holes. The height of each corrugated fin preferably ranges from 6 to 9 mm. The parallel flow warm-air core body has the advantages as follows: firstly, heat exchanging efficiency is improved to the maximum extent, and the surface temperature of the warm-air core body can be more uniform; secondly, the parallel flow warm-air core body has the characteristic of light weight; thirdly, the processing technology is simple, and the parallel flow warm-air core body is suitable for mass production; and fourthly, the parallel flow warm-air core body is convenient to install, and the production efficiency of an evaporator assembly is improved.

Description

technical field [0001] The invention relates to a parallel flow warm air core body. It belongs to the field of air conditioning. It is especially suitable for engineering vehicle air conditioners. Background technique [0002] With the continuous development of the engineering vehicle industry, the vehicle air conditioner has become an indispensable part of the vehicle, and the heater core is an important part of the air conditioner for the engineering vehicle. At present, most of the heater cores used in engineering vehicles are copper tube aluminum sheet type, with uneven surface temperature, low heat transfer efficiency and high cost. Due to the harsh working environment of engineering vehicles, the heater core body of the above structure is not resistant to wind blockage, and has poor anti-attenuation performance; in addition, the flat tube of the heater core body of the existing automotive air conditioner heater is generally single-hole or two-hole , the strength is ...

Problems solved by technology

At present, most of the heater cores used in engineering vehicles are copper tubes and aluminum sheets, with uneven surface temperature, low heat transfer efficiency and high cost.

Due to the harsh working environment of engineering vehicles, the heater core body of the above structure is not resistant to wind blockage, and has poor anti-attenuation performance; in addition, the flat tube of the heater core body of the existing automotive air conditioner heater is generally single-hole or two-hole , the strength is low, and the pressure resistance performance cannot meet the requirements of engineering vehicles
