Abstract
The invention discloses a novel heat-pipe-type solar water heater collector which combines a heat collection plate coated with a selective absorption coating, a forged heat absorption plate and a shell together to serve as a heat absorption body, and has a heat transfer characteristic of a heat pipe. The forged heat absorption plate and the heat collection plate coated with the selective absorption coating respectively serve as a heat absorption end and a heat release end of the heat pipe, a liquid absorption core is attached to the inner wall of a sealing space between the heat absorption end and the heat release end, and operating fluid is filled in the sealing space. By virtue of the heat transfer of the heat pipe, the heat transfer capacity of a solar water heater is improved, and the thermal efficiency is improved.
Description
Technical field
The present invention relates to solar energy utilization technique, refer in particular to and a kind ofly will be coated with the collecting plate of coating for selective absorption and absorber plate and the shell of forging forming combines as absorber, make it to have the heat collector of solar water heater of adopting heat pipes for heat transfer characteristic.
Background technology
At solar energy heat utilization field, the multiple matured product of vacuum tube water heater and flat water heater has appearred comprising in solar water heater, and the plate type solar water heater is opened up markets rapidly with its longer service life and easy installation method.But because larger, the hot water programming rate of heat loss and Amplitude Ratio vacuum tube water heater are slightly poor, still can not adapt to northern cold climate.
At present existing a plurality of patents about the plate type solar water heater, but the patent that coating for selective absorption directly is plated on the flat thermal-collecting tube is not yet found.Below list several existing Patents:
(application number: 99218284.0) propose a kind of water heater, its absorber is that two metallic plates consist of to patent " efficient freeze proof plate type solar water heater ", is full of water in the gap between two metallic plates, and the absorber upper surface is coated with coating for selective absorption.Because the water yield in the absorber gap is fewer, when water freezing expanded, change in volume was within the regime of elastic deformation of metallic plate, and can guarantee can be not freezing.
Patent " the built-in many block combination flat panel types solar water heater of circulation pipe " (application number: 200920253847.5) propose a kind of modular plate type solar water heater, this device is designed to the unit that module is with the heat collection body of water heater, is convenient to install and transportation.
Patent " a kind of wall mounted integral pressure-bearing flat plate solar water heater " (application number: 201020192486.0) propose a kind of solar water heater that thermal-arrest layer and storage tank are integrated, the loss of minimizing heat transmission course.
Summary of the invention
The present invention proposes a kind ofly will be coated with the collecting plate of coating for selective absorption and absorber plate and the shell of forging forming combines as absorber, makes it to have the heat-pipe type heat collectors for solar water heater of adopting heat pipes for heat transfer characteristic.This heat collector is made of insulation shell, transparent cover plate, water inlet pipe, outlet pipe and absorber.Absorber comprises that the collecting plate that is coated with coating for selective absorption, absorber plate, liquid-sucking core, heat pipe hydraulic fluid and the shell that forging and pressing have pit consist of, wherein collecting plate and absorber plate seal welding, post liquid-sucking core at absorber plate pit inwall, and be filled with the heat pipe hydraulic fluid, make the pit after the sealing form a heat pipe structure.Shell and absorber plate sealing combination, the space between both is as heating and the flow channel of water.The distribution of forging and pressing pit on the absorber plate that pit is arranged is uniformly, and the degree of depth of pit is consistent and will guarantee the heat pipe normal operation.After the pit opening part was sealed by collecting plate, the heat pipe structure that consists of will guarantee not communicate with other heat pipes.
