Description

Flat-plate multi-purpose solar collector

technical field

The utility model relates to a solar heat utilization device, in particular to a flat plate multi-purpose solar heat collector.

Background technique

With the rapid development of the economy, energy shortage has become a bottleneck restricting the economic development of various countries. As a clean energy source, solar energy is favored by countries all over the world as an inexhaustible source of energy. With the continuous development of solar energy technology, many product technologies are quite mature, and there are more and more types of solar air heat collectors, but for now, there are still some shortcomings in solar air heat collectors, such as single function, only It is used to heat water or only to heat air, the temperature rise is small, and the structure is complex, the cost is high, the strength is low, the durability is poor, the circulation speed of the heat medium is too slow, and the system temperature cannot be adjusted according to the needs, etc.

Utility model content

The purpose of the utility model is to provide a flat plate multi-purpose solar heat collector with high heat collection rate, small heat loss and controllable temperature.

In order to achieve the above purpose, the utility model adopts the following technical solutions: a flat plate multi-purpose solar collector, including a thermal insulation base plate and a light-transmitting cover body, the light-transmitting cover body is sealed and installed on the heat preservation base plate, and the gap between the light-transmitting cover body and the heat preservation base plate A closed space is formed between them. A heat collecting plate is installed on the thermal insulation floor in the closed space, and a heat collecting cover is sealed and installed on the heat collecting plate. A closed heat collecting cavity is formed between the heat collecting cover and the heat collecting plate. There is a grid with holes, and the grid divides the heat collecting chamber into interval heating chambers. One end of the heat collecting cover is connected with a water inlet pipe, and the other end is connected with a water outlet pipe.

The outer layer of the heat collecting cover is coated with a heat absorbing film layer.

The water inlet pipe extends out of the light-transmitting cover body.

The water outlet pipe extends out of the light-transmitting cover body and is connected with the delivery pipe through the pump body.

The flat plate multi-purpose solar collector adopts the above structure. The grid with holes divides the heat collecting chamber into multiple heating chambers. The water enters the first heating chamber from the water inlet pipe for heating, and then flows into the second heating chamber through the opening of the grille. The two heating chambers are heated, and this is repeated, and the water flowing through the heating chamber is heated repeatedly under the action of the solar heat absorbed by the heat collecting cover, and the pump body sucks the hot water into the conveying pipeline and conveys it to the place where the heat is needed; this utility model The new type adopts a perforated grille to divide the heat collection chamber into interval heating chambers and connect the heating chambers in series, so that the heating distance and heating time of the water are increased, the heat collection efficiency of the heat collection device is greatly improved, the water temperature at the outlet is increased, and the heat collection The cover is located in the airtight space formed by the light-transmitting cover body and the thermal insulation base plate, which is less affected by the external environment, and the heat loss of the system is minimized. Different situations of demand; combined with the structural design of the utility model, it has the advantages of high heat collection rate, small heat loss, strong durability, controllable temperature, low cost and applicable to various flow media.
