Heat-exchanging type solar water heater

Abstract

The invention relates to a heat exchange type solar water heater, which comprises a heat exchanger, and a heater equipped with water storage tanks and heat collection pipes. The heat exchanger comprises an outer water storage chamber and an inner water storage chamber fixedly arranged inside the outer water storage tank, an outer water tank water inlet pipe and an outer water tank water outlet pipe with length longer than that of the outer water tank water inlet pipe are provided inside the outer water storage chamber, and the lower ends of the outer water tank water inlet pipe and outer water tank water outlet pipe are both passed out of the shell of the outer water storage chamber; an inner water tank water inlet pipe and an inner water tank water outlet pipe with length longer than that of the inner water tank water inlet pipe are provided inside the inner water storage chamber, and the lower ends of the inner water tank water inlet pipe and inner water tank water outlet pipe are both passed out of the shell of the inner water storage chamber, wherein the inner water tank water inlet pipe and inner water tank water outlet pipe are respectively connected with a water outlet port and a water inlet port of the water storage tank via water pipes. The invention can provides domestic bathing hot water with stable temperature, and the heat collection pipes and water tanks can be arranged at any height, so that the arrangement and usage are both convenient.

Description

technical field [0001] The invention relates to a solar heating device, in particular to a heat exchange type solar water heater. Background technique [0002] With the development of society and the enhancement of people's awareness of energy saving, solar water heaters have become the heating equipment of choice for families. Existing solar water heaters include a water storage tank and a heat collecting tube. Water is stored in the water storage tank during use. The water inlet and outlet pipes of the water storage tank are directly connected to tap water and shower equipment, and the heat collecting tube absorbs solar energy to heat the water. This solar water heater is to directly use the water after heating for family bathing, and its water temperature stability is poor, and it is hot and cold, and it is not convenient for people to bathe and use. In addition, the traditional solar water heater needs to use the pressure difference of hot water to press the water out, ...

AI Technical Summary

Problems solved by technology

This kind of solar water heater uses the heated water directly for family bathing.

In addition, the traditional solar water heater needs to use the pressure difference of the hot water to press the water out, and the heat collecting pipe and water tank should be installed in a higher place, usually on the roof, which is troublesome to install and is not suitable for high-rise buildings with more than 10 floors.
