Wind-power rotary disc type viscous friction water heater

Abstract

The invention relates to a wind-power rotary disc type viscous friction water heater which comprises a fan, a gear case and a friction water heater body. The friction water heater body comprises a disc rotary shaft, a heating chamber, a rotary disc, a water cavity, a baffling plate, a cold water inlet and a hot water outlet. The fan rotates under the wind power effect, the rotary kinetic energy of the fan can be steered by the gear case at variable speed and then is transferred to the disc rotary shaft, and the disc rotary shaft drives the rotary disc to rotate at certain rotation speed. The rotary disc is arranged in the heating chamber, the heating chamber is full of a high-viscosity fluid, and the rotary disc and the high-viscosity fluid produce heat serving as a heat source for heating through friction when the rotary disc rotates. Water flows into the friction water heater body through the cold water inlet, the water and the fluid in the heating chamber perform heat exchange through a dividing wall to improve the temperature, and the water flows out of the hot water outlet when being needed by a user. The wind-power rotary disc type viscous friction water heater utilizes wind power mechanical energy to directly produce hot water, an electric heating link is avoided, a water heating process can be simplified, energy utilization rate can be improved, and the wind-power rotary disc type viscous friction water heater is suitable for domestic, industrial and ship hot water supply in regions rich in wind energy.

Description

technical field [0001] The invention relates to the fields of new energy utilization and water heaters. Specifically, the present invention relates to a wind-driven rotary disc viscous friction water heater that converts wind energy into heat energy. Background technique [0002] Solar water heaters are currently the most widely used new energy water heaters. However, solar water heaters are greatly affected by sunlight, and their heating efficiency is not high in rainy days and winter. Wind energy and solar energy have a certain degree of complementarity. When the sunshine is not sufficient, wind energy can be used to heat water, improve the utilization rate of new energy, and meet user needs to a greater extent. At the same time, wind energy can also be used independently to realize the hot water function. [0003] From the perspective of domestic existing technologies, wind energy water heaters mainly include power generation type, heat pump type, friction type and other...
