Construction flat plate shaped split wall hanging vacuum solar superconducting heat collection apparatus

Abstract

The invention discloses a building flat plate shaped split typed wall-mounted vacuum solar energy superconductive heat collector, comprising a separating heat pipe formed by a flat plate collector with an automatic liquid separator, a circulating steam pipe, a circulating liquid pipe, a condenser and a heat accumulator. A plurality group of precise metering holes and capillaries are horizontally distributed between a liquid storage accumulator and a finned tube which are communicated with the circulating liquid pipe. The work condition of balanced film high temperature evaporation can be realized. The heat collector is characterized in that the heat collector has high temperature heat collection output, high efficiency and high energy heat transmission, long distance circulation without pump, low temperature and freeze proof, can be harmonized with buildings, is economical, has long service life and so on. The heat collector exploits the novel applied field of the solar energy with high temperature and separation structure, which can form devices of solar energy boiled water generator, radiant heater, air conditioner, additional water heater, etc. The heat collector is presented in a square and flat shape, which can be mounted and hung on the roof, the wall, the position above the window, the position below the window and the balcony of the buildings, is beautiful and harmonious. The heat collector is suitable for being used in high rise buildings with multiple floors, which is an ideal technology of solar energy for building integration.

Description

technical field [0001] The invention belongs to the technical field of solar photothermal application, and relates to a solar heat collection and heat transfer device, in particular to a superconducting heat transfer solar heat collection device with a split structure for building inlay or hanging. Background technique [0002] The solar equipment composed of in-line glass vacuum heat collectors widely used in China is represented by water heaters. Because of its inherent disadvantages such as affecting the appearance of buildings, easy scaling, water storage in pipes, and freezing of systems, there are great limitations in its application; now there are The split wall-mounted building-integrated solar water heater has a flat and square shape of the collector, which can be combined with the beauty of the building. The accumulator water tank can be separated from the collector and placed indoors for easy heat preservation and prolonging life. The main defect of the vacuum tub...

Problems solved by technology

However, the above-mentioned technology still has the following obvious deficiencies: 1. The circulating medium or circulating water needs a special circulating pump and controller and consumes a lot of power, otherwise the transmission distance is short, and it is difficult to separate the heat collector and the water tank to an ideal distance position; 2. , The system passes through multi-stage sensible heat transfer, the temperature difference is large, the thermal efficiency is poor, the heat gain temperature is low, the heat transfer effect and heat collection effect are not good, and the energy density is small, it is difficult to adapt to high temperature applications such as absorption refrigeration; 3. The system is complex, The heat transfer coefficient is low, the parts and pipes are large in size and consumables, and the manufacturing cost is high; 4. The life of the circulation pump and heat pipe is difficult to exceed 15 years, and the maintainability and economy are not good
