Description

a heat collector

technical field

The utility model relates to a heat collector. the

Background technique

At present, the heat transfer medium in the collector is generally liquid, with a high boiling point temperature, which can only absorb energy higher than its temperature, and requires a certain intensity of light to exert its heating effect. It is greatly affected by the weather and cannot fully meet daily needs. , and the energy extraction rate of the heat collecting tube is not high due to the shape, layout and other reasons. the

Contents of the invention

The purpose of this utility model is to provide a heat collector which can absorb solar energy, wind energy and water energy, and has a reasonable layout of heat collecting tubes and a high energy extraction rate in order to solve the above-mentioned deficiencies in the prior art. the

In order to achieve the above purpose, a heat collector designed by the utility model includes a shell, the shell is equipped with a heat collecting tube, and the heat collecting tube is equipped with a heat transfer medium, and the feature is that the heat collecting tube At the inlet, it is divided into a plurality of branch pipes, and the adjacent two branch pipes are connected at intervals. Each of the branch pipes is divided into two branch pipes. Secondary communication, the heat transfer medium is gas refrigerant. The branch pipes and the branch pipes are connected with each other to balance the flow rate and make it smoother; the structure is simple and the installation is convenient; the boiling point of the gas heat transfer medium is low, generally below zero, which is lower than the daily ambient temperature. When there is no sunlight, Energy can be extracted from water in wind or rain, and the energy has a wide range of applications. It can absorb wind energy, water energy and solar energy in the environment and turn it into heat energy, which is more energy-saving. the

As a further improvement and supplement of the above structure, the utility model also includes the following additional technical features or any combination of these features:

The heat collecting tube is formed by inflation and has an integrated structure, which has good heat conduction effect; it can also be split and installed in the shell. the

The adjacent branch flow pipes communicate at intervals to balance the flow velocity in each branch flow pipe. the

The various branch flow pipes are connected to each other multiple times at the outlet of the heat collecting pipe in a grid-like structure, so as to avoid excessive air pressure and congestion at the outlet when the heat transfer medium flows into the outlet from multiple branch flow pipes. the

The gas heat transfer medium is refrigerant R134A or R407C, with boiling points of -26.1 degrees and -43.6 degrees respectively, which ensures heat extraction and heat exchange efficiency, and is more environmentally friendly. the

The inlet and outlet of the heat collecting tube are arranged on the same side of the housing, which is convenient for installation and conforms to the principle of arc design. the

The heat collecting tube involved in the utility model adopts the way of two diversions, and the tubes are connected to each other, so that the flow rate is balanced and smoother; the boiling point of the gas heat transfer medium is lower, generally below zero, which is higher than the daily ambient temperature. Low, can absorb wind energy, water energy and solar energy in the environment, and turn it into heat energy, which is more energy-saving and efficient; and it has a simple structure and is easy to install. the
