Problems solved by technology

However, the characteristics of the existing superconducting fluid are organic, which determines that the height of each column of this vacuum radiator cannot be greater than 500mm. If the height is greater than 500mm, the superconducting fluid will not work, and the vaporized superconducting fluid cannot rise. And form a loop, the higher part does not release heat, but absorbs heat, and the heat load of each column is 70-80 watts under the condition

Abstract

The invention relates to superconducting fluid and a vacuum radiator using the same. The superconducting fluid consists of potassium dichromate, calcium chloride, anhydrous ethanol, sodium perborate, boric acid, manganese dioxide, sodium peroxide, zinc hydroxide and distilled water. The invention further provides the vacuum radiator using the superconducting fluid, which comprises a plurality of radiating fins and a heat medium runner pipe arranged at the bottom parts of inner cavities of the radiating fins, wherein the plurality of the radiating fins are arranged in parallel and mutually communicated, vacuum pumping ports are arranged at the upper parts of the radiating fins, the superconducting fluid is arranged in the inner cavities of the radiating fins, and the height of each radiating fin is 950mm-1100mm. The superconducting fluid is inorganic, non-toxic to a human body, incombustible, and non-freezing at minus 40 DEG C, and can be gasified at 40 DEG C and not corrode metal; and the heat load of each column in the vacuum radiator is 170-200 watts, thereby being applicable to more places, having good indoor heat release effect, saving the number of the columns in the indoor radiator and simultaneously saving steel.

Description

technical field [0001] The invention relates to a superconducting fluid and a vacuum radiator using the superconducting fluid. Background technique [0002] At present, most of the radiators used for heating in winter in the north use hot water as the heat source to fill the entire cavity space. Therefore, the radiator can effectively heat the room only after the water in the cavity reaches a certain temperature. , This heating method consumes a lot of energy, increases the heating cost, and has low heat transfer efficiency and slow heating speed. [0003] In order to improve the shortcomings of traditional radiators, a vacuum superconducting radiator has appeared on the market. The inner cavity of the radiator is evacuated to form a negative pressure in the inner cavity, and a small amount of superconducting liquid is sucked in. Under the action of negative pressure, the heat medium When the temperature is low, the superconducting liquid at 40°C to 50°C can be vaporized, m...
