Tracking heat storage solar water heater without water tank

Abstract

The invention relates to the field of solar water heaters, in particular to a tracking heat storage solar water heater without a water tank. Evacuated collector tubes are vertically arranged on the inner surface of a light gathering groove, the bottom of the light gathering groove is fixedly connected with a connecting box, the connecting box is movably connected to a connecting pipe, the connecting pipe is arranged on the top of a base, and a control device is arranged on the surface of the base. By the adoption of the technical scheme, the tracking heat storage solar water heater has the beneficial effects that mounting is easy, convenience and practicality are achieved, and the evacuated collector tubes can be increased or reduced according to the requirements of users; and due to the design of automatic sun tracking, the irradiation time of the evacuated collector tubes is longer, and more heat is gathered. A stable heat storage effect is achieved, cold water is rapidly heated, thewater heater can supply hot water immediately after being started when water is needed on user sides, waste of the cold water is reduced, the old water problem is solved by means of the design that the water tank is not arranged, and the quality of outflow water is good.

Description

technical field [0001] The invention relates to the field of solar water heaters, in particular to a tracking heat storage tankless solar water heater. Background technique [0002] A solar water heater is a heating device that converts sunlight energy into heat energy, and heats water from low temperature to high temperature, so as to meet the hot water use in people's life and production. Solar water heaters are divided into vacuum tube solar water heaters and flat plate solar water heaters according to their structure. The vacuum tube solar water heaters are the main ones, accounting for 95% of the domestic market share. Vacuum tube household solar water heaters are composed of heat collecting tubes, water storage tanks, brackets and other related parts. The conversion of solar energy into heat mainly depends on vacuum heat collecting tubes. Get the hot water you need. [0003] Solar energy (Solar Energy) generally refers to the radiant energy of sunlight. Solar energy ...

AI Technical Summary

Problems solved by technology

The heating time of the vacuum heat collecting tube can only be when the sun is shining, and the position of the sun changes in a day. Since the position of the vacuum heat collecting tube of the water heater is fixed, the degree of solar radiation that can be received It is changing, that is, the solar water heater’s heat collection time and heat collection angle are limited by the change of the sun’s position, resulting in unstable heat collection and poor heat collection effect.
