A kind of flat through-type solar heat collector and its manufacturing method

Abstract

The invention discloses a plate straight through type solar heat collector which comprises a heat exchange box and a plate heat collecting device. An inner box body is arranged in the heat exchange box, the outer side of the inner box body is wrapped by a box interlayer, a vacuum layer is arranged between the box interlayer and the inner box body, a water inlet pipe and a water outlet pipe are arranged on the lower portion of the inner box body, a cold water main pipe and a hot water main pipe which extend out of the heat exchange box are arranged on the side face of the inner box body, the cold water main pipe is arranged on the upper half portion of the inner box body, the hot water main pipe is arranged on the lower half portion of the inner box body, a plurality of cold water branch pipes are arranged at the tail end of the cold water main pipe, and a plurality of hot water branch pipes are arranged at the tail end of the hot water main pipe. When solar heat collection is carried out, the plate heat collecting device is adopted, a straight through heat collecting pipe arranged inside can rotate along with an angle adjusting device on the heat collector, it is guaranteed that sunlight directly irradiates the straight through heat collecting pipe, sunlight heat radiation is absorbed to the maximum, and then the overall heat efficiency of the solar heat collector is improved.

Description

technical field [0001] The invention belongs to the field of solar energy applications, in particular to a flat through-type solar heat collector and a manufacturing method thereof. Background technique [0002] In the heat utilization of solar energy, the key is to convert the sun's radiant energy into heat energy. Because the solar energy is relatively scattered, it must be concentrated, so the heat collector is a key part of various solar energy devices. Due to different purposes, collectors and their matching systems are divided into many types with different names, such as solar cookers for cooking, solar water heaters for hot water, solar dryers for drying items, solar dryers for Solar furnaces for smelting metals, as well as solar houses, solar thermal power stations, solar desalination devices, etc. With the improvement of people's living standards, more and more solar energy has entered people's daily lives. Solar water heater is one kind. Due to the geographical ...

Due to different purposes, collectors and their matching systems are divided into many types with different names, such as solar cookers for cooking, solar water heaters for hot water, solar dryers for drying items, solar dryers for Solar furnaces for smelting metals, as well as solar houses, solar thermal power stations, solar desalination devices, etc. With the improvement of people's living standards, more and more solar energy has entered people's daily lives. Solar water heater is one kind. Due to the geographical location and the fixed angle of the solar collector installation, and the cylindrical vacuum heat collecting tube is fixedly installed in the frame, the surface of the cylindrical vacuum heat collecting tube exposed to the sun will be small and cannot be effectively used. Absorb solar radiation, heat utilization rate is not high
