Wing box microgroove heat pipe heat collecting plate, composed shutter flat-plate solar heat collector and application

Abstract

The invention provides a wing box microgroove heat pipe heat collecting plate. A metal blank is extruded and formed to form a microgroove heat pipe box, then the microgroove heat pipe box and a solarradiation heat absorbing plate serving as a heat pipe box packaging face are connected in an extrusion manner to form a wing box microgroove heat pipe in a sealed manner, and the wing box microgrooveheat pipe heat collecting plate is manufactured by vacuumizing a working medium vacuum/ injection pipe reserved on the microgroove heat pipe box and filling a heat pipe heat exchange working medium. The surface of the solar radiation heat absorbing plate is coated with a solar selective absorbing film, and therefore the heat collecting and heat transferring integrated function of the wing box microgroove heat pipe heat collecting plate is achieved. The wing box microgroove heat pipe heat collecting plate is connected through bolts, buckles, welding and other methods, and a shutter flat-plate solar heat collector composed of the wing box microgroove heat pipe heat collecting plate is formed. The wing box microgroove heat pipe heat collecting plate is simple in manufacturing process, high inintegration degree, good in anti-freezing performance, modular in structure and flexible and free in assembling, the optimal inclination angle can be used, the building modulus is matched, and good application and popularization prospects are achieved.

Description

technical field [0001] The invention relates to the field of flat solar heat collectors, in particular to a wing box micro-groove heat pipe heat collector plate, a louver flat solar heat collector composed of it and its application.

Problems solved by technology

In this kind of heat pipe flat plate heat collector, the heat pipe and the heat absorbing plate are manufactured separately step by step, and then the method of completing the overall assembly of the heat collecting plate elements by welding process has the following disadvantages: first, the welding process requires high requirements, and the manufacturing process is cumbersome and costly. High, difficult, and low efficiency; second, when the heat pipe and the heat-absorbing wing are welded, the welding zone is not completely continuous, which will lead to a large heat transfer resistance of the weld, and its heat collection efficiency is greatly affected by the efficiency of the wing; third, Existing heat pipes and heat collector plates are prone to ablation and penetration when using thin-walled materials for welding connection, resulting in scrapping
