Integrated pressure-bearing heat pipe flat-plate solar water heater

Abstract

The invention discloses an integrated pressure-bearing heat pipe flat-plate solar water heater and belongs to the field of flat-plate solar water heaters. The solar water heater comprises main components, such as a water tank, a flat-plate heat collector, a bracket and the like, wherein a heat absorption plate core of the flat-plate heat collector is formed by welding a heat pipe and an aluminum plate or a copper plate on which a heat absorption coating is plated; and a condensation section of the heat pipe is positioned outside the heat collector and inserted into the water tank and directly exchanges heat with water in the water tank. Due to an integrated design, the flat-plate solar water heater has the characteristics of high heat collection efficiency and heat absorption speed, compression resistance, frost resistance, high impact resistance, long service life and the like.

Description

technical field [0001] The invention discloses a flat solar water heater with integrated pressure-bearing heat pipes, which belongs to the field of flat solar water heaters. Background technique [0002] Flat-panel solar water heaters can be divided into split-type flat-panel solar water heaters and integrated flat-panel solar water heaters according to their structural forms. The split-type flat-panel solar water heater is separated from the collector and the water tank and connected through a circulating pipe; the integrated flat-panel solar water heater is mainly composed of a heat collector, a water tank and a bracket, and the structure is a fixed whole. [0003] Ordinary integrated flat-panel solar water heaters are actually the same as natural circulation split flat-panel solar water heaters in principle, except that the distance between the collector and the water tank is closer, and the connecting pipe in the middle is shorter than the split type, so the middle one ...

AI Technical Summary

Problems solved by technology

[0003] Ordinary integrated flat-panel solar water heaters are actually the same as natural circulation split flat-panel solar water heaters in principle, except that the distance between the collector and the water tank is closer, and the connecting pipe in the middle is shorter than the split type, so the middle one The heat loss is smaller, the thermal performance of the water heater is better, but the antifreeze performance is poor

Although the vacuum tube of the vacuum tube solar water heater is directly connected to the water tank, the heat loss is smaller, and it also has a certain antifreeze performance, but the vacuum tube solar water heater has many essential shortcomings, such as: explosive tube, short life, and the water tank is not under pressure. Wait

There is also a heat pipe type vacuum tube solar water heater. The main difference from the vacuum tube solar water heater is that it uses heat pipe technology. After the heat conduction tube, the vacuum tube water heater has greatly enhanced the frost resistance and made the system able to operate under pressure, but it still has the defect of the vacuum tube
