Folding-type microchannel porous flat pipe and molding method thereof

Abstract

The invention discloses a folding-type microchannel porous flat pipe and a molding method thereof. The flat pipe is formed by subjecting a single thin slab to integral molding, and the single thin slab is sequentially advanced by a mechanical bending mechanism in a multi-point molding control manner, wherein two ends of the single thin slab are respectively bent circuitously, then the circuitously bent parts are vertically bent twice and then horizontally turned and folded once and are butt-jointed at a mesal position of the single thin slab for integral molding, and thus, a porous flat pipe with mutually spaced fine pores is further formed. Compared with the prior art, the invention has the beneficial effects that: 1, the structural form of the flat pipe disclosed by the invention is suitable to being used in a light-weight heat exchanger with light weight and high heat conductivity; 2, the advantages of compact entire structure, high heat exchange efficiency, light weight, firmness, durability, and operation safety and reliability are achieved; 3, by adopting the integral folding and molding structure, the energy consumption of a product production process is low, and the pressure resistance of products is good; and 4, the effect of producing and yield can be achieved through mechanical control, the inventory level is greatly reduced, the product turnover efficiency is increased, and the requirement on lean production can be met.

[0002] At present, with the miniaturization of mechatronic systems and chemical mechanical systems, traditional heat exchange equipment can no longer meet the basic requirements of application systems. The development of miniaturization of heat exchange equipment has become an urgent requirement and an inevitable trend. On the other hand, with the increasingly prominent energy problems, it is required to reduce the volume of heat exchange equipment as much as possible under the premise of satisfying heat exchange, that is, to improve the compactness of heat exchange equipment, thereby reducing the weight of heat exchange equipment and saving materials. , and correspondingly improve the space utilization

A key technology for the miniaturization of heat exchange equipment is the miniaturization and high efficiency of heat exchange flat tubes. It is difficult for existing heat exchange flat tubes to meet this development requirement, so it is necessary to make corresponding technical improvements.
