Abstract

The utility model relates to a four-season used close circulation type solar energy water heater. The utility model has the main improvement that a single water tank is changed into a plurality of water tanks 10 for enlarging water volume; the panel 5 of a heat collector and the panel 2 of the water tank adopt the same corrugated plate with circular arc-shaped corrugation, and the soleplate 4 of the heat collector and the soleplate 15 of the water tank are the same plate; a cavity 3 which is arranged between the panel 5 and the soleplate 4 of the heat collector is directly communicated with the water tanks 10; the heat collector 11 and the water tanks 10 are connected into integration, and are both sealed in a shell body. Compared with the prior art, the utility model absorbs light and heat in the mode of direct radiation, and the vertical plane and the extended surface of light irradiation are enlarged; therefore, thermal efficiency is high, a fully sealed structure is arranged for reducing heat loss and increasing the effect of heat preservation, and the utility model with easy fabrication and low cost can be operated in four seasons.

Description

The four seasons are used vexed loop solar water heater

The utility model relates to a kind of solar water heater, exactly is to the passive solarenergy water heater of band heat collector and the improvement of vacuum pipe solar water heater.

A kind of is the isolating construction that closing-sunning type band heat collector separates with water tank, though its water tank has heat-insulating property preferably, but heat collector mostly adopts copper aluminium composite sheet to make the glass card as the thermal-arrest plate, and form thermal-collecting tube at interval by the punching press of double-deck glass card, this structure is not only made complexity (needing special production line), welding difficulty, and on the heat absorption principle, be at the glass card by solar irradiation, thermal-collecting tube in the middle of being transmitted to removes heat medium (water) again, enters water tank again.Thereby efficient is low reaches 40%-50%, moreover can only be used for sunny and outdoor temperature higher season.

Another kind of vacuum pipe solar water heater, though done to improve greatly in heat-insulating property, the four seasons can be moved, the cost costliness, vacuum tube is easy to burst, because endotherm area is less, severe winter can only shine had a bath in 2-3 days.

The purpose of this utility model is at above-mentioned two kinds of technical deficiencies, and a kind of thermal efficiency height is provided, and high insulating effect is made simply, and low four seasons of cost are with the vexed formula solar water heater that follows.

The purpose of this utility model realizes with following technical scheme: fundamentally change the conduction mode of heating of heat collector, heat collector is designed to be made up of thermal-arrest plate and base plate, between thermal-arrest plate and the base plate cavity is arranged, the structure that cavity directly is communicated with water tank.The panel of heat collector is directly contacted with medium (water), overcome the secondary conduction, improved efficient, and heat collector and water tank be connected as a single entity, all be closed in the same housing, make it have good heat absorption, heat insulation effect.In order to strengthen the water capacity of water heater, do not influence endothermic effect again, become a plurality of little water tanks by a water tank and be connected as a single entity, not only strengthen water capacity but also strengthened the mechanical strength of water tank.

Fig. 1 is a structure diagram of the present utility model

Fig. 2 is a plan structure sketch of the present utility model

Fig. 3 is that the A of heat collector 11 among Fig. 2 is to view

The utility model is described in further detail below in conjunction with drawings and Examples.

Include housing 1, transparent cover plate 5,6 on the housing 1, heat-insulation layer 9 in the housing 1, heat collector 11, water tank 10 and overflow pipe 8, the vexed formula solar water heater that follows of water inlet pipe and water outlet pipe 12, its main improvements are heat collector 11 and water tank 10, and wherein heat collector 11 forms 5 by collector panels 5 and base plate 4, between 4 and glass line shape cavity 3 is arranged, cavity 3 directly is communicated with water tank 10.Heat collector 11 is connected as a single entity with

water tank

10 and 10 and 11 all is closed in the housing 1.

The panel 5 of above-mentioned heat collector 11 adopts garden arc glass card, concrete available aluminium, galvanized sheet system glass line.Water in the cavity 3 of heat collector 11 and the water in the water tank 10 are under the effect of water temperature difference and water-head, formed complete natural gravity circulation, the heat that thermal-arrest plate 5 is gathered, directly absorbed by the water in the thermal-arrest plate 5 following cavitys 3, this direct radiation absorbs the characteristics of photo-thermal, has the higher thermal efficiency.The panel 2 of water tank 10 is identical circular arc glass cards with collector panels 5, has so not only increased endotherm area, and has increased the vertical plane of illumination, and purpose all is for improving the thermal efficiency.In reality was made, collector panels 5 was same complete glass cards with water tank panel 2.Heat collector 11 is entities with water tank 10, and all is enclosed in the structure in the housing 1, can reduce heat and distribute, and improves heat insulation effect.In order further to improve heat insulation effect, the transparent cover plate on the housing 1 is made up of double glazing unit (or sun composite plate) 6,7.

As complete structure of the utility model and common design, overflow pipe 8 on the water tank 10, and overflow pipe 8 is provided with steam vent 14, the water inlet pipe and water outlet pipe 12 of heat collector 11 bottoms is communicated with cavity 3, the supporting position of water heater, adopt tilt stand 13, its angle of inclination is determined by the latitude in the area of using water heater.

The utility model is compared with existing technology in vacuum tube, and the higher thermal efficiency is arranged, and makes simply, With low cost, detect through reality, heat absorption efficiency of the present utility model can reach 70%, in the winter time ambient air temperature In the time of-15 ℃, water temperature still can reach about 50 ℃, is a kind of solar water heater of four seasons operation.
