Description

The enhanced heat exchange solar water heater

The utility model relates to a kind of sunlight and infrared ray heat cold water through enhanced heat exchange solar water heater that absorbs.

Normally used solar water heater has airfoil type, vacuum tube type and plate, and the deficiency of its existence is that heating is slow, and efficient is low, and single function (can only manufacture hot water) winters such as can not being used.

Goal of the invention of the present utility model is to provide a kind of heating fast, and thermal efficiency height has the solar water heater that difunctional (burning heat, boiling water), the four seasons can both use.

Implementer's case of the present utility model is: form solar water heater by water receiver, the water central layer that scribbles heat-absorbing paint, inlet channel, outlet conduit etc., water central layer inside is that intersect, intercommunication in length and breadth enhanced heat exchange water channel, its vertical water channel cross section is that wave is dolioform, similar a plurality of low-speed wind tunnel makes the symbol of longitudinal pressure gradient variable; Its cross channel inwall has the lines that can increase inner wall roughness, and lines constitute certain angle in the tube wall direction, and the heat exchange effect is strengthened.

Feature of the present utility model also is the check valve and the gate valve that have the water that can make water receiver to enter the water central layer on the pipeline, and the pipeline that water receiver is connected with the water central layer, with the binary cycle system of constitution system, and prevents that hot water from refluxing.

The cross section of said cross channel is polygon or isosceles trapezoid, and the best is flat hexagon, and the lines of its duct wall are 45 ° at the best angle of the tube wall direction of cross channel, and the water central layer is formed by steel plate or aluminium sheet compacting.

Fig. 1, Fig. 2 are structural representation of the present utility model;

Fig. 3, Fig. 5 are partial sectional view of the present utility model;

Fig. 4 is the profile of Fig. 3.

Below in conjunction with accompanying drawing the utility model is described in further detail:

Among Fig. 1,1 is water central layer body, and 2 is storage tank, and 3 is support.

Among Fig. 2, pipeline 6 and 11 makes water central layer 1 be connected with water receiver 2, and cold water is from joint 8 water inlets, and hot water is emitted from pipe joint 4, and water receiver lid 9 is done maintenance or do not had the running water user and make into cold water usefulness.10 is ball float.It is sewage draining exit that gate valve 7 and check valve 5,14 are arranged on the pipeline 6.Water central layer 1 is pressed into half dolioform (isosceles) by copper coin or aluminium sheet, and two opening and closing are got up then, with taking out heart rivet, are welded with argon arc.Water central layer 1 inside is the 2M that the intercommunication water channel of the enhanced heat exchange of intersection in length and breadth constitutes ²The water central layer, laterally be 74 water channels 12, vertically be 13 water channels 13, be coated with the thick heat-absorbing paint of last layer 0.5～0.8mm on water central layer surface, and select for use China to copy and produce the thick Filon-solor glass-reinforced plastic material of 0.75mm, carry out heat insulationly at last at copper coin or the aluminium sheet back side with the insulation of litaflex material, make frame with section bar all around and constitute a box water central layer heat collector.

Among Fig. 3, Fig. 4, the section of cross channel 12 is flat hexagon, and its length of side is 10mm, and middle diagonal is 20mm, and h is 2～7mm, and its transverse inner wall is the roughness at the high multi-line of 0.2mm 16 angles at 45.

Among Fig. 5, vertically the vertical section of water channel 13 is the dolioform road 15 of wave.

The water central layer of the utility model by heat-absorbing paint absorbs sunlight and infrared ray is gathered heat, the water that cold water is heated in the water central layer, circulation by binary cycle system, make hot water enter water tank, cold water arrives heating again in the water central layer again, the circulation exchange is constantly risen water temperature like this, till available.Mainly utilize thermosiphon principle in Natural Circulation, hot water rises, the Natural Circulation that cold water sinks, and in systemic circulation, mainly utilize temperature pressure difference to circulate, so continuous exchange reaches till the requirement temperature water.

Intercommunication water channel and the two cyclic system of the utility model because the reinforced heat exchanger that intersects is in length and breadth arranged System compared with prior art, has good effect of heat exchange, and heating is fast, the efficient advantages of higher.
