Background

Full aluminium formula microchannel inserted sheet formula parallel flow heat exchanger is a section and replaces the internal thread copper pipe with the aluminum flat tube of microchannel to carry out the heat exchanger that the heat exchange was carried out through the refrigerant, and traditional copper aluminium heat exchanger makes circular copper pipe pass through the aluminum fin for the aluminum fin passes through high-speed punch press punching press out circular port, makes copper pipe outer wall and fin hole combine closely through the expand tube to the copper pipe afterwards, and the refrigerant flows in the copper pipe, reaches the purpose of heat transfer. The all-aluminum type micro-channel heat exchanger is widely applied to the field of automobiles and household single-cooling air conditioners, and is structurally characterized in that an aluminum fin is clamped between every two aluminum flat tubes, so that the heat exchanger is analogized, a set of heat exchanger is formed by brazing, however, the fin structure of the traditional all-aluminum type heat exchanger and the assembly mode of the fin and an aluminum tube cannot finish vertical drainage, condensed water on the heat exchanger cannot be discharged, and the purpose of saving cost and improving efficiency can be achieved due to the fact that the all-aluminum type heat exchanger cannot be used. The inserted sheet type parallel flow heat exchanger solves the problems of heat exchange and water drainage by changing the structure of the aluminum fins, so that the product is different from an all-aluminum type parallel flow heat exchanger. In the all-aluminum microchannel cold and warm dual-purpose parallel flow heat exchanger, the structure of the aluminum fin is different from that of the existing product, and the product has the advantages of high heat exchange efficiency, reduced refrigerant consumption and reduced manufacturing cost. Experiments prove that the heat exchange efficiency is 1.3 times of that of the copper pipe aluminum fin. The product can replace copper pipe aluminum sheet heat exchanger, and can reduce the product cost of heat exchanger by 30%. The energy-saving effect and the cost saving are obvious, and the future popularization trend is very clear.

The applicant has a heat exchanger core body integrated assembly unit, can realize automatic press fitting of a core body after fin discharging, but before automatic press fitting, assembling of a collecting pipe and a micro-channel flat pipe is required to be completed. When assembling the collecting pipe and the micro-channel flat pipes, the distance between the micro-channel flat pipes needs to be divided and simply fixed, and then the micro-channel collecting pipe is assembled left and right. For example, the method of dividing the micro-channel flat tubes one by one is time-consuming, and the full-automatic tube distribution machine sold in the market is very expensive, so that the applicant designs a simple tube distribution mounting mechanism for assembling the collecting pipe and the micro-channel flat tubes.
