Abstract
The utility model discloses a concentrator of a flat tube type solar water heater, which is capable of directly plating selective absorption coatings on the outer surfaces of heat absorption tubes. In the concentrator, the heat absorption tubes with the sections being flat and rectangular are arranged tightly in parallel, and the selective absorption coatings are plated on the surfaces of the sides exposed to the sun of the heat absorption tubes to be adopted as heat absorption bodies, thereby simplifying the process of transmitting heat to water, and avoiding thermal contact resistance. Simultaneously, the narrower side wall of the heat absorption tube has the function of intensifying heat transmission.
Description
One, technical field
The present invention relates to solar energy utilization technique, refer in particular to and a kind of coating for selective absorption is plated in solar water heater heat absorption heat pipe surface, replace the heat absorption hot plate part of conventional flat template water heater, and the flat pipe type heat collectors for solar water heater that forms.
Two, background technology
At solar energy heat utilization field, the multiple matured product of vacuum tube water heater and dull and stereotyped 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, still can not adapt to the northern cold cold weather because bigger, hot water programming rate of heat loss and amplitude are poorer slightly than vacuum tube water heater.
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 found as yet.Below list several existing related patent U.S. Patent No.:
(application number: 99218284.0) propose a kind of water heater, its absorber is that two metallic plates constitute 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, Volume Changes was within the regime of elastic deformation of metallic plate, and can guarantee can be not freezing.
Patent " the built-in many piecemeals assembled flat of circulation pipe type solar water heater " (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 hanging whole 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.
Three, summary of the invention
The utility model proposes a kind of flat pipe type heat collectors for solar water heater that coating for selective absorption directly is plated in the thermal-collecting tube surface.The flat pipe type heat collectors for solar water heater is made up of inlet channel, outlet conduit, endothermic tube, lagging casing and transparent insulation cover plate.Inlet channel, outlet conduit and endothermic tube weld together, and the endothermic tube cross section is flat rectangle, must must closely not interspace side by side, and the side external surface that endothermic tube faces south is coated with coating for selective absorption (side that faces south should be flat).Water directly absorbs heat on tube wall after getting into endothermic tube through inlet channel, has simplified endothermic process, has improved the heat transmission speed.
Four, description of drawings
Below in conjunction with accompanying drawing, the utility model is described further.
Fig. 1 is the overall schematic of this device.
Fig. 2 is the absorber sketch map figure of this device.
Fig. 3 is this device absorber side view figure.
Fig. 4 is this device endothermic tube sectional view.
The position of marking is respectively among the figure: 1, insulation shell; 2, transparent insulation cover plate; 3, inlet channel; 4, endothermic tube; 5, outlet conduit.
Five, the specific embodiment
Below in conjunction with accompanying drawing, the embodiment of the utility model is described further.
The external attemperater of the inlet channel of flat pipe type heat collectors for solar water heater and outlet conduit, water in water tank gets in the endothermic tube of heat collector through inlet channel.The cross section be flattened rectangular endothermic tube on the sunny side a side external surface be coated with coating for selective absorption, absorbing solar energy converts heat energy into endothermic tube is heated up, and the inner water of water back.Ducted water is through circulating, and is stored in the attemperater after being heated to uniform temperature.The tube wall of the narrow side of flat tube has the effect of strengthening heat exchange.
Claims (2)
1. flat pipe type heat collectors for solar water heater; This device is made up of lagging casing (1), transparent insulation cover plate (2), inlet channel (3), endothermic tube (4), outlet conduit (5); Wherein: endothermic tube (4) closely side by side; Do not stay the gap between any two, weld together with inlet channel and outlet conduit.
