Embodiment Construction

[0014] figure 1 Among them, a flat transparent body 2 bonded with an aluminum sheath 1 with a U-shaped cross-section and a shell 5 integrally manufactured with the frame 3 and the condenser 4 are bonded and sealed to form an integrated light-transmitting enclosure container6. The light-transmitting closed container 6 contains an absorber 9 which is manufactured integrally with the evaporator 7 and has many small holes 8 . Between the permeable body 2 and the housing 5, many supports 10 passing through the small holes 8 of the absorber 9 are used to support against negative pressure. The support 10 is not in contact with the pores 8 of the absorbent body 9 .

[0015] The light-transmitting closed container 6 adopts a recessed heat-insulation sleeve 11 to reduce heat loss at the junction of the inlet and outlet water barges 12 . The inner end of the heat insulating sleeve 11 is sealed and connected to the barge 12 , and the barge 12 passes through and protrudes from the heat ...

Abstract

The invention relates to a method for providing vacuum heat insulation for a solar system by a negative pressure source. A transparent closed container, a solar energy collecting and utilizing device, a measurement and control system and the negative pressure source are utilized to form an active vacuum solar energy collecting and utilizing system, and the negative pressure source and the closed container are communicated to form a vacuum heat insulation layer. The active vacuum solar energy collecting and utilizing system of the method comprises the transparent closed container, the solar energy collecting and utilizing device, the measurement and control system and the negative pressure source and is characterized in that an exhaust channel is arranged between the transparent closed container and the negative pressure source. The method can solve the problem of vacuum degree reduction because of material exhaust and helium permeation. A common sealing technology can be used for manufacturing various new vacuum solar energy collecting and utilizing products, thereby enlarging the selection range of materials and processes. The service life of the products can be synchronized with buildings, and the heat energy cost is low. A jacket is adopted so as to be helpful to solve the problem of size errors of glass tube plates, and the closed container made of a thin curtain wall glass sheet has good heat insulation and convenient use. Five embodiments are given by combining attached pictures.

Description

Technical field [0001] The invention relates to a method and equipment for providing vacuum heat insulation for a solar energy system by using a negative pressure source. Background technique [0002] The use of vacuum insulation can effectively improve the temperature and efficiency of solar heat collection. The vacuum heat insulation layer of existing products is formed during the manufacture of heat collecting elements and is maintained by sealing.
