Description

Fast Cycle Solar Air Heater

technical field

The utility model relates to a device for utilizing solar energy, in particular to a device for collecting solar energy and air heat.

Background technique

With the rapid economic development, energy shortage has become a bottleneck restricting the economic development of various countries. In order to save energy, reduce energy consumption, and ensure the healthy and stable development of my country's economy, the state has formulated and compiled a series of energy-saving policies. Among these policies, the state has made the use of new energy and renewable energy a key task. Solar energy is favored by countries all over the world as a clean energy source and an inexhaustible source of energy. With the continuous development of solar energy technology, solar collectors have met the world, but as far as the current solar collectors are concerned, there are some disadvantages: such as small temperature rise, complex structure, high cost, low strength, and durability. Poor sex and so on.

In the patent 02289421.7, a solar collector is proposed. Air is input from the gas inlet on the gas inlet header, enters the heat collecting glass tube, and then is output from the gas outlet on the gas outlet header, wherein the heat collecting glass tube Mounted with a heat-absorbing layer, although it can also achieve the purpose of heating the air, but because there is no transparent cover, it is easy to make the external air flow and take away part of the heat, which is not conducive to the rapid heating of the air in the tube.

A solar collector proposed in patent 200620003545.9 uses an air intake square tube box to input air into the ribbed heat-absorbing gusset plate for heating, and then outputs it from the air outlet square tube box for use. The air inlet and outlet square tube box and the ribbed heat absorber The gusset plate is fixedly connected to the insulation board and then covered with a transparent cover plate on the upper part. Although the air is heated up like this, the shape and structure are relatively complicated, and custom mold processing is required, and the cost is relatively high.

Utility model content

The purpose of the utility model is to provide a solar heat collector which can use solar energy to quickly heat the air, has a simple structure and is low in cost.

In order to achieve the above object, the utility model adopts the following technical scheme: a fast-circulation solar air heat collector, including an air inlet pipe, an air outlet pipe, a heating pipe and a thermal insulation bottom plate, and the air intake pipe and the air outlet pipe are fixedly connected to the thermal insulation bottom plate. A heating pipe is fixedly connected between the air inlet pipe and the air outlet pipe, and the three form a passage, and a heating tube core board is arranged on the heating pipe.

A glass cover is also covered outside the heating pipe, the heating tube core plate, the heat preservation bottom plate, the air inlet pipe and the air outlet pipe.

The material of the heating tube is a copper tube and the outer layer is coated with a selective absorption film, and the material of the heating tube core board is a copper foil rib plated with a selective absorption film, and the two are welded and connected.

A pump is fixed at the mouth of the air outlet pipe.

Bolts or expansion bolts are used to connect the air inlet pipe and the heat preservation bottom plate, and between the air outlet pipe and the heat insulation bottom plate.

There are at least three air heat collecting cores.

When working, the air is input from the air inlet pipe to the heating pipe. Because the heating pipe and the heating tube core board absorb solar energy, the heating pipe heats up and then transfers the heat to the air, which can make the air heat up quickly. At the same time, the air inlet pipe and the air outlet pipe are not only used as cool air. It can also be used as a bracket to support and connect the whole device; use a glass cover to cover the heating pipe, heating tube core board, heat preservation bottom plate, air intake pipe and air outlet pipe, and the glass cover and heat preservation A closed space is formed between the bottom plates, the heat loss is minimized, and the influence of the external cold wind is also small, so that the temperature environment of the heating tube and the heating tube core board is relatively stable, which is conducive to heating up; the material of the heating tube is selected with high thermal conductivity The copper tube is equipped with a heating tube core board made of copper foil ribs on the outside, and the outer layer of the copper tube and copper foil ribs is coated with a selective absorption film, so the heat absorption efficiency is higher and the temperature rises faster. At the same time The material for processing copper foil ribs can be processed with industrial scraps, thereby saving resources and reducing costs; a pump is fixed at the mouth of the air outlet pipe, which facilitates the flow of air from the air inlet pipe to the air outlet pipe, so that the efficiency of the entire device is improved. Faster; the use of bolts or expansion bolts to fix the air inlet and outlet pipes can be fixed more firmly, which is convenient for maintenance; there are at least 3 air heat collecting cores, and there can be more, which is also to improve the efficiency of the entire device.

Detailed ways

The fast-circulating solar air heat collector shown in Figure 1 and Figure 2 includes an air inlet pipe 1, an air outlet pipe 5, a glass cover 7, an insulation base plate 4, a pump 9, several heating pipes 3 and heating elements welded on both sides of the heating pipe 3 The tube core plate 2, the lower end of the heating pipe 3 is inserted into the air inlet pipe 1 and communicated with the air inlet pipe 1, the upper end of the heating pipe 3 is vertically inserted into the air outlet pipe 5 and communicated with the air outlet pipe 5, between the air inlet pipe 1 and the heat preservation base plate 4, the air outlet pipe 5 and the air outlet pipe 5 Bolts 6 are used to connect the insulation bottom plates 4 . There is a glass cover 7 at the heating pipe 3, the heating tube core plate 2, the heat preservation base plate 4 and the air inlet and outlet pipes 1,5, and the pump 9 is arranged at the outlet pipe 5 nozzles.

The material of the heating tube 3 is copper tube and the outer layer is coated with a selective absorption film, and the material of the heating tube core board 2 is copper foil ribs and coated with a selective absorption film.

When working, the air enters the heating pipe 3 from the air intake pipe 1. Since the heating pipe 3 and the heating die plate 2 absorb solar energy, the heating pipe 3 heats up and then transfers the heat to the air. A closed space is formed between the glass cover 7 and the heat preservation base plate 4. The heat loss is reduced to the greatest extent, so that the temperature environment where the heating tube 3 and the heating tube core board 2 are located is relatively stable, and the air can be heated up quickly; the pump 9 at the mouth of the air outlet pipe 5 accelerates the flow rate of the air, so that the entire device Efficiency increases faster.
