Separate heat pipe wall mounting type flat-plate solar heating device

Abstract

The invention discloses a separate heat pipe wall mounting type flat-plate solar heating device. The separate heat pipe wall mounting type flat-plate solar heating device comprises an indoor unit and an outdoor unit which is connected with the indoor unit; the outdoor unit comprises an evaporator; the evaporator comprises a heat absorbing plate core and an evaporation section of a separate heat pipe integrally molded with the heat absorbing plate core; the indoor unit comprises a condenser which comprises a condensation section of the separate heat pipe; the gaseous phase part of the evaporator is connected with the gaseous phase part of the condenser through a gas guiding pipe; and the liquid phase part of the evaporator is connected with the liquid phase part of the condenser through a liquid guiding pipe. According to the mode, the separate heat pipe wall mounting type flat-plate solar heating device provided by the invention has the advantages of realizing solar photothermal conversion and heat energy transmission by adopting a separate heat pipe technology as well as solar heating, greatly improving the heating efficiency, reducing the heat loss and realizing the antifreezing problem of a flat-plate solar collector and a system pipeline.

Description

technical field The invention relates to the field of solar heat utilization, in particular to a wall-mounted flat panel solar heating device with separated heat pipes. Background technique According to the division of building thermal engineering, more than 2 / 3 of my country's land area belongs to severe cold and cold areas. In order to ensure the basic conditions of survival, buildings must be heated. With the improvement of living standards and living environment, heating requirements in hot-summer and cold-winter regions continue to increase. Most households in cities and towns have installed air conditioners to solve their own heating problems in winter. In 2004, my country's urban buildings consumed 130 million tons of standard coal per year for heating, equivalent to about 10% of coal production. Compared with solar hot water heating alone, the energy saving obtained by solar heating and heating is greater. Therefore, solar heating is another solar thermal utilizat...

AI Technical Summary

Problems solved by technology

This has the following disadvantages: a. The temperature of the hot water produced is in the high temperature zone of 45°C-60°C, especially in winter when the light intensity is low, and the efficiency of the collector is low; b. After secondary heat exchange (heating the heat first The water is then heated by hot water to heat the air), the system efficiency is low; c, the system antifreeze problem is difficult to solve; d, the system is complicated, and the initial investment is high; e, due to the low system efficiency, there are various safety hazards, the initial investment is high, and the operation and maintenance costs High, difficult to popularize and apply
