Description

A dual-cycle high-efficiency energy-saving radiator

Technical field

The utility model relates to the technical field of heat supply, in particular to a high-efficiency heat dissipation device using a superconducting medium for double circulation.

Background technique

Most of the existing heat circulation radiators are connected with two parallel horizontal tubes and vertical tubes. The heat transfer medium enters through an opening of the upper horizontal tube. One of the outlets goes out and enters the large circulation of the heating system. This kind of radiator needs to heat a large amount of medium in the system pipeline, and the distance of the pipeline is long, so the heat loss is large, the heat transfer efficiency is low, and the temperature rise rate is very slow, which greatly reduces the utilization of heat energy. In order to improve the heat transfer effect of the radiator, some currently circulate the heat transfer medium in the tube cavity of the radiator itself while improving the heat transfer efficiency of the piping system. For example, Chinese patent CN200820024035.9, a utility model patent named "A Silent High-efficiency Energy-saving Superconducting Radiator", improves the radiator's efficiency by circulating the heat transfer medium inside the radiator and the circulation of the heating pipeline system. heat transfer effect. But there is obvious deficiency in this patent technical scheme. Due to this technical proposal, one or more layers of metal wire sound-absorbing nets are arranged on the surface of the heat source pipe in the inner cavity of the lower connecting pipe. It is precisely because of these metal wire silencing nets that the original narrow medium channel becomes narrower, thus hindering the circulation of the medium inside the radiator and affecting the heat transfer effect. It is estimated that the heat transfer efficiency of this structure is reduced by about 50%.

Contents of the invention

In order to solve the structural deficiencies of the existing radiators, the utility model provides a double-cycle high-efficiency energy-saving radiator with high thermal efficiency and fast heat transfer.

The technical solution adopted by the utility model to solve the technical problem is: the double-circulation high-efficiency energy-saving radiator includes an upper connecting pipe, a lower connecting pipe, and a heat dissipation pipe arranged between the upper connecting pipe and the lower connecting pipe, which are connected to each other. A superconducting medium is arranged in the tube cavity, mainly a heat source casing is arranged in the cavity of the lower connecting pipe, and heat exchange fins are arranged on the outer wall of the heat source casing.

In order to improve the circulation speed and heat transfer effect of the medium inside the radiator, the heat exchange fins are arranged axially or radially on the outer wall of the heat source casing.

In order to facilitate maintenance, a variable plug can be set at one end of the upper connecting pipe.

Compared with the prior art, the utility model has the advantages of good heat transfer effect, fast heating and high temperature. Since the heat exchange fins are arranged axially or radially on the outer surface of the heat source sleeve, the heat absorbed by the heat source sleeve can perform rapid heat exchange with the superconducting medium through the heat exchange fins. Heat is exchanged with the air during the upward cycle, releasing heat. Therefore, this kind of radiator has good heat transfer efficiency, fast temperature rise, high temperature, and uniform surface temperature, and the heat exchange efficiency is increased by 50%. If DFL-CN-1 superconducting medium is used, the entire radiator can achieve the best heating effect within two minutes.
