Totally closed internal light condensation medium temperature solar flat plate heat collector

Abstract

The invention belongs to the technical field of solar heat collectors and particularly provides a totally closed plate type solar heat collector. The heat collector is a medium temperature heat collector capable of providing hot water or steam higher than 100 DEG C. The totally closed internal light condensation medium temperature solar flat plate heat collector consists of a casing, a glass cover plate, a solar heat collecting plate and a heat collecting pipeline. A heat preserving material is filled in a cavity portion, a solar heat collecting plate core consists of a light condensing plate with a circular arc shaped cross section and a heat absorbing pipe, wherein the arc-shaped circle center of the light condensing plate is located on the outer circumference of the heat absorbing pipe, the heat absorbing pipe is located above a circular arc in the light condensing plate, and a heat absorbing coating is plated on the surface of the heat absorbing pipe. The casing is basin-shaped, the glass cover plate is arranged on the casing, the glass cover plate, the lower portion of the light condensing plate of a frame and a heat collector frame are sealed through sealing strips, the heat preserving material is filled under the light condensing plate and in a cavity of the heat collector, and the heat absorbing pipe is communicated with a hot water circulating pipeline. The flat plate heat collector has the high-heat-collection area but reduces the heat radiating area, simultaneously adopts a totally closed tank body structure and thoroughly avoids a breathing phenomenon.

Description

technical field [0001] The invention belongs to the technical field of solar heat collectors, and more specifically relates to a fully enclosed plate-type solar heat collector, which can provide hot water or steam of more than 100 degrees in the field of medium-temperature heat collectors. Background technique [0002] The solar collectors currently on the market have the following advantages and disadvantages: [0003] advantage: [0004] 1. The solar panel collectors have uniform specifications and good consistency. At present, the standard specification of 2 meters × 1 meter is basically adopted at home and abroad. It has low cost, is convenient for building installation design, and at the same time, it is reliable for installation and use. It is integrated with the building after being installed on the appearance of the building, and even the building is directly used as a curtain wall. . Relatively speaking, the vacuum tube collectors are of different sizes and disor...
