Water heating blanket and heating water circulation system

Abstract

The invention discloses a water heating blanket. The water heating blanket comprises a water flow channel and a phase-change material channel which are densely distributed in the water heating blanketbody. The water flow channel and phase-change material channel are parallelly arranged, and locked and fixed by hoops. Circular heating water is flowed in the water flow channel, and the phase-changematerial channel is internally provided with a phase-change material and a heating wire for heating. The beneficial effect of the water heating blanket is that the potential safety hazard caused by the breaking and burning of the heating wire can be avoided because the water heating blanket insulates and stores the heat based on the phase-change material, and the energy is saved and the consumption is reduced because the water heating blanket takes part in the large circulation of the heating water in a water heater and a heating system.

Description

technical field [0001] The invention belongs to the technical field of heating equipment, and in particular relates to an energy-saving water heating blanket and a heating water circulation system. Background technique [0002] In the prior art, a water pipe with a heating wire is arranged inside the water heating blanket, and the heating wire heats the water to achieve a heating effect, which has a warm and non-drying effect, and is safer than an electric blanket; however, because the heating wire in the water pipe uses water For heating medium, when the heating wire is broken, there is still the danger of leakage and fire; [0003] The gas water heater can transfer heat to the heat exchanger by burning gas, and make the cold water in the heat exchanger be heated into hot water for bathroom or heating. A large amount of smoke will be emitted during the heating process. The temperature of the flue gas can generally reach above 150°C. The existing hot water heater directly d...

[0002] In the prior art, a water pipe with a heating wire is arranged inside the water heating blanket, and the heating wire heats the water to achieve a heating effect, which has a warm and non-drying effect, and is safer than an electric blanket; however, because the heating wire in the water pipe uses water For heating medium, when the heating wire is broken, there is still the danger of leakage and fire;

[0003] The gas water heater can transfer heat to the heat exchanger by burning gas, and make the cold water in the heat exchanger be heated into hot water for bathroom or heating. A large amount of smoke will be emitted during the heating process. The temperature of the flue gas can generally reach above 150°C. The existing hot water heater directly discharges this part of the flue gas, which causes waste of the heat of the flue gas. In addition, the hot water heater itself will be obviously hot during the heating process. If it is used for a long time, it will inevitably affect the service life of the water heater;

[0004] In addition, the water in gas-fired water heaters, heaters and water heating blankets commonly used in the prior art for indoor heating generally realize small circulation in their respective systems, resulting in high energy consumption and serious waste of water resources;
