Abstract
The utility model relates to a vacuum plate type solar energy collector, which is composed of a vacuum glass heat insulating cavity, an insulating box body and a metal heat collector, wherein, the metal heat collector is arranged in the vacuum glass heat insulating cavity. The utility model can be used for directly feeding hot water or injecting other working media to form a heating tube heat collector. The utility model has the advantages of large effective area of receiving solar energy, high thermal efficiency, high pressure of a bearing system, low heat loss coefficient, operation of four seasons, simple structure, and low cost, does not freeze tubes at low temperature, does not burst and is the ideal product selected by extensive crowd.
Description
The utility model relates to a kind of solar thermal collector, particularly a kind of plate evacuated solar collector.
Existing in the market solar thermal collector by its structural shape, can be divided into board-like and tubular type; By its operation principle, can be divided into directly-heated type and heat pipe-type.They have separately advantage and shortcoming respectively:
1, ordinary flat formula heat collector, cover plate are the single-glass plate, and effective area is big, cost is low.Since direct contact environment atmosphere, the heat loss coefficient height, and can't use icing season, can only be used for the torrid areas.
2, all-glass vacuum tube type solar thermal collector, because vacuum layer separates heat collector and atmosphere, heat loss coefficient is low, but the four seasons use, but leak water in the pipe, when sunlight was arranged, the high water of directly going up of blank pipe temperature easily burst, can not pressure-bearing, the thermal-collecting tube volume is big, is arranged with the gap, and effectively collector area is little, the manufacturing process complexity, the cost height.
3, heat-tube vacuum tubular type heat collector is adopting heat pipes for heat transfer, and is sealed in the vacuum tube, pipe explosion, and system's pressure-bearing height, the thermal efficiency is higher, but four seasons use exists volume big equally, is arranged with the gap, and effective area is little, shortcomings such as manufacturing cost height.
The purpose of this utility model is, overcomes the shortcoming of above-mentioned heat collector, and a kind of high-effect, long-life, solar thermal collector cheaply are provided.
The purpose of this utility model is achieved in that mainly and is made of vacuum glass insulation cavity, insulation casing and collector metal device that described collector metal device is between vacuum glass insulation cavity and insulation casing.
Described vacuum glass insulation cavity, its inside is evacuated.
