Flat plate type collector

Abstract

The invention provides a flat plate type collector, and relates to the technical field of solar heating. The flat plate type collector comprises a heat collecting plate core and a frame; and the heatcollecting plate core comprises two layers of heat collecting plates and a layer of heating tubes, the two layers of heat collecting plates are tightly pressed into a whole, the heating tube is located between the two layers of heat collecting plates, the tube wall of the heating tube is tightly attached to the inner walls of the heat collecting plates, and the heat collecting plates are embeddedinto the frame. According to the flat plate type collector, the outer wall of the heating tube is tightly attached to the inner walls of the heat collecting plates, the contact area of the heating tube and the heat collecting plates are the area of the tube outer wall of the heating tube (namely the heat exchange area of the heat collecting plate and the heating tube), the heat exchange area between the heat collecting plate and the heating tube is large, so that heating efficiency of the heating tube and a working medium is high.

Description

technical field [0001] The invention relates to the technical field of solar heating, in particular to a flat plate heat collector. Background technique [0002] A solar collector is a device that converts the sun's radiant energy into heat energy. According to different uses, the collector and its matching system have different names, such as solar cookers for cooking, solar energy for hot water Water heaters, solar dryers for drying items, solar furnaces for smelting metals, as well as solar houses, solar thermal power stations, solar desalination devices, etc., because the solar energy is scattered, it must be concentrated, so the heat collector The inverter is a key part of various solar energy devices. [0003] The heat collector is also called the heat collector plate, which is the name of the solar energy industry for the outdoor heat collecting parts of the solar water heater. The main function of the heat collector is to collect the heat energy in the sunlight and ...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is to provide a flat-plate heat collector to solve the problem of heat transfer efficiency between the heat-collecting plate and the heating pipe as the heating tube in the flat-plate heat collector existing in the prior art is directly welded on the heat-collecting plate. Low, which leads to the technical problem of poor heating effect of the collector
