Superconducting heat pipe-type heat exchanger and liquid filling method thereof

Abstract

The invention relates to a superconducting heat pipe-type heat exchanger and a liquid filling method of the heat exchanger. The superconducting heat pipe-type heat exchanger is a sealed communicated closed-loop circulating system consisting of a hot air pipe, an overflow port seal head, a condensation sleeve, a gas-liquid hole, a condensation chamber, a reflux pipe, a liquid filling three-way valve, a heat collector / evaporator. The liquid filling method comprises the following steps: filling a superconducting liquid medium into a filling liquid meter which is connected with the liquid filling three-way valve through a liquid filling pipe; opening a valve element of the liquid filling three-way valve; and squeezing a piston of the filling liquid meter to fill the superconducting liquid medium into the closed-loop circulating system consisting of the heat collection / evaporator, the hot air pipe and the like. The superconducting heat pipe-type heat exchanger has the advantages of low manufacturing cost, high heat transfer speed, long service life, no mechanical operation, extremely low fault rate, high heat exchange efficiency and the like.

Description

technical field [0001] The invention belongs to the field of heating equipment, in particular to a superconducting heat pipe heat exchanger and a liquid filling method thereof. Background technique [0002] At present, solar heat pipe technology is mostly used in compact vacuum tube solar water heaters, while solar water heating projects use multiple heat pipes to combine to the header for heat exchange, and then the heat of the header is forced to circulate through antifreeze and water, and then transported to the heat preservation water tank It is a kind of semi-superconducting heat pipe and semi-antifreeze circulation solar heat collection circulation system, which has many problems. For example, the heat exchange efficiency is low, the controller and the circulating water pump often fail during operation, the low temperature resistance is poor, the service life is short, and the circulation system is often damaged by freezing, so it cannot be widely used.

Problems solved by technology

For example, the heat exchange efficiency is low, the controller and the circulating water pump often fail during operation, the low temperature resistance is poor, the service life is short, and the circulation system is often damaged by freezing, so it cannot be widely used.

[0003] Flat plate collectors have a technical bottleneck problem of fear of freezing, which has not been solved so far. How to apply superconducting heat pipe technology to large-scale flat-plate heat collection projects and split-type flat-plate solar collector systems to solve the low-temperature frost resistance problem and become a solar energy A major technical problem in the industry, especially when the flat superconducting heat pipe system is filled with medium, it needs to be evacuated and exhausted at the installation site, and then filled with superconducting liquid, which is difficult to master even for technicians with certain professional knowledge, resulting in There is a lot of non-condensable gas in the heat pipe tube, which eventually leads to problems such as no heat transfer and low heat transfer efficiency.
