Vacuum heat collector

Abstract

The invention relates to a vacuum heat collector, which mainly comprises a vacuum cavity and a heat transfer unit, wherein the vacuum cavity comprises a cavity wall and a plurality of temperature conducting particles, the cavity wall defines a chamber, the temperature conducting particles are suspended in the chamber, the temperature conducting particles can generate vibration after being heated, are mutually collided and can release the heat energy, the heat transfer unit comprises at least one temperature superconducting pipe, and the temperature superconducting pipe connects the vacuum cavity and a heat source, and is used for conducting the heat energy generated by the heat source to the vacuum cavity. Thereby, the invention can release the heat energy through the vacuum cavity, and the vacuum cavity can compensate the consumption in the heat energy transfer process, and can effectively improve the heat efficiency, so the invention has high practicability.

Description

technical field [0001] The invention relates to a heat collecting device, in particular to a vacuum heat collecting device which can generate electric energy by using temperature difference. Background technique [0002] In daily life, there are many consumed energy generated but wasted heat energy, such as: water heaters, high-temperature flue gas produced by burners, waste heat emitted by factories, geothermal heat...etc. If the thermal energy can be properly utilized, it will become a renewable energy that meets the needs of environmental protection. [0003] There are many products on the market, such as thermoelectric materials (thermoelectric), heating devices, incubators, boilers, drying devices, etc., which can recover waste heat and convert it into electrical energy or heat energy to achieve resource recovery and energy reuse. Efficacy, but has considerable utility value. [0004] However, during the recovery process of the above-mentioned waste heat, due to the i...

Problems solved by technology

[0004] However, during the recovery process of the above-mentioned waste heat, due to the influence of terrain, environment, distance and other factors, the loss of heat energy is quite serious, and the heat transfer effect is better, resulting in a low recovery rate of waste heat, and it can only be applied to close-by It is far away from the place where waste heat is collected, but there are deficiencies such as insufficient practicability and poor thermal effici...
