Rapid uniform heating solar water heater and its dynamic heating method

Abstract

The invention relates to a solar water heater with rapid and even heating and a dynamic heating method thereof, and comprises an outer shell, a thermal insulation layer, an inner liner, a heat collector and a support. One side of the inner liner is provided with a water inlet pipe, the other side of the inner liner is provided with a water outlet pipe and a heater, a valve is connected on the water outlet pipe, one side of the inner liner is provided with a circulating water inlet, the circulating water inlet is connected with a circulating water pump by a circulating pipe, and the circulating water pump is connected on a circulating water outlet by the circulating pipe. The solar water heater carries out the circulating promotion by the circulating water pump with the tiny power consumption, the distribution of the hot water in the inner liner is even, the water temperature of the outlet water has no temperature difference, thus greatly improving the comfort of shower; the solar water heater can carry out the rapid and even heating to obtain the hot water, which is further characterized by long service life of the heater, short heating time, high efficiency and simple structure due to the reduction of the generation of water scale of the heater.

Description

technical field [0001] The invention belongs to the technical field of water heaters, and relates to a fast and uniform solar water heater and a dynamic heating method thereof. Background technique [0002] With the improvement of people's living standards, solar water heaters have entered thousands of households. Hot water is widely used in bathing, washing hands, laundry, dishes, vegetables, etc., especially in winter, the amount of hot water is large, which makes solar water heaters The design capacity of the water tank is getting larger and longer, and the water tank is getting longer and longer, which puts forward higher requirements for the water temperature balance and heating speed in the heating process. At present, for large-capacity solar water heaters, whether using a heat pump heat exchanger or an electric heating tube as a heater for auxiliary heating in cloudy and rainy days, the water temperature needs to be set before use. Power cut off to stop heating to g...

AI Technical Summary

Problems solved by technology

The main problem is: the heater is located on one side of the water tank, and the heating is realized by the heat transfer between the water and the water. If it is high for a long time, the heater is prone to scaling, which will reduce the thermal efficiency of the heater and shorten the service life. The cold water in the outlet pipe, and then the hot water problem
