Abstract

The utility model relates to a parallel flow type solar energy water heater, which comprises a pressure pipe, a heat gather pipe and a water outlet pipe. The utility model is characterized in that the heat gather pipe is one or a plurality of telescoping pipelines which are connected in parallel between the pressure pipe and the water outlet pipe; the diameter of the joint with the pressure pipe and the water outlet pipe is small, and the diameter of the rest is big; the pressure pipe is communicated with a tap water pipe or a water tank whose water level is higher than the water level of the outlet pipe; the pressure pipe and the water outlet pipe are both the telescoping pipelines that the diameters of both ends are small and the diameters of middles are big; the pressure pipe is arranged on the oblique lower part of the heat gather pipe; the water outlet pipe is arranged on the oblique upper part of the heat gather pipe; the pressure pipe, the water outlet pipe and the heat gather pipe are connected together and arranged on a corresponding thermal insulation seat. The utility model cancels the thermal insulation water storage tank of high cost. The cost of the parallel flow type solar energy water heater is reduced more than 40% than the cost of the existing solar energy water heater with a same capacity, and the effect of thermal insulation is not changed. One sink or one water tank whose level is higher than the water outlet pipe is enough for the spacious rural area without the tap water.

Description

The downflow type solar water heater

The utility model is a kind of downflow type solar water heater.

Prior solar water heater, generally be divided into two parts, i.e. heat build-up sheet and water butt, its operation principle is: utilize the formed density contrast of water temperature difference to circulate, carry out continuous exchange by the water that temperature is lower in pipeline and the insulation water butt after the heat build-up of heat build-up sheet, to reach the purpose that adds hot water.The insulation effect of this water heater mainly concentrates on the water butt, and just bag is made one deck heat-barrier material around bucket.The material that the heat build-up sheet adopts mainly contains copper pipe, aluminum pipe or vacuum tube, and the latter half of pipe also is embedded in the heat-barrier material, and the mode that Gong discharges water mainly contains single tube for putting two kinds of formula and two-tube entrance and exit types.

Prior solar water heater is owing to all be that water butt and heat build-up sheet are separated, thermal loss is more in cyclic process, main is that water butt and heat build-up pipe all must adopt the higher material of price to make the structure of insulation effect, its production technology more complicated, manufacturing cost is high, also is difficult to use for most of peasants.

The purpose of this utility model will propose a kind of by held concurrently thermal-arrest and store insulation effect of heat build-up pipe, and cheap solar water heater is to overcome the shortcoming of existing technology.

This downflow type solar water heater that the utility model proposed, it has water inlet pipe, heat build-up pipe and outlet pipe, be primarily characterized in that described heat build-up pipe is that one or more is parallel to the reducer pipe between water inlet pipe and outlet pipe, with water inlet pipe and outlet pipe be connected the place diameter little, the diameter of remainder is big, and water inlet pipe is communicated with the water tank that running water pipe or water level are higher than outlet pipe.

Water inlet pipe and outlet pipe also are the big reducer pipes of the little mid diameter of two ends diameter, and water inlet pipe places the oblique below of heat build-up pipe, and outlet pipe places the oblique upper of heat build-up pipe, and water inlet pipe has blow-off pipe.

After linking into an integrated entity, heat build-up pipe, water inlet pipe and outlet pipe be positioned on the corresponding insulation seat, the insulation seat is partly plating inlet tube and outlet tube and heat build-up pipe, be divided into many cells and spaced-apart to reduce the cross-ventilation amount to greatest extent in the cavity of insulation seat, the thickness of heat-insulation layer generally will reach more than the 40mm.

The upper surface of insulation seat has the transparent panel that prevents that air from flowing and daylighting is used, and the insulation seat is the 15-30 degree and is placed on the frame.

Place the use that to be together in series between same heat build-up pipe, water inlet pipe and outlet pipe group on the insulation seat.

Advantage of the present utility model is the poly-insulation water storage tank that has disappeared and involved great expense, its effect is replaced by heat build-up pipe and the outlet pipe that capacity has increased, thereby raw material and manufacturing process have been saved, its cost has reduced more than 40% with the capacity solar water heater than existing, heat insulation effect is then constant, for the vast rural area of no running water, can use as long as adorn pond or the water tank that a position is higher than outlet pipe; Because water of the present utility model is to enter the heat build-up pipe from being positioned at the next water inlet pipe, entering outlet pipe from the heat build-up pipe again flows out, it is the circulation of downflow type, this and more existing first inlet water tanks, flowing to the heat build-up pipe from water tank again compares from the solar water heater that the heat build-up pipe flows to the reverse-flow circulation of water tank again, overcome the shortcoming that has hot water directly not use, thereby more flexible be suitable for, easilier accepted by people.

Engage accompanying drawing and example below and further specify the utility model.

Accompanying drawing 1 is front view of the present utility model (frame is not drawn).

Accompanying drawing 2 is A-A profiles of the utility model insulation seat.

Accompanying drawing 3 is B-B profiles of the utility model insulation seat.

Accompanying drawing 4 is front views of the utility model heat build-up pipe, water inlet pipe and outlet pipe group.

Shown in Fig. 1-4.Water inlet pipe (4), heat build-up pipe (2) and outlet pipe (1) are all done the pipe of reducing or non-pipe not of uniform size.The diameter of heat build-up pipe can reach more than the 100mm, and every root volume reaches more than the 60L, and general 1-4 root parallel connection is one group.The material that uses can be a galvanized sheet, and stainless steel or aluminium alloy are made the back blacking so that be heated.The general poly-stupid vinylic foam with easy reflective and difficult conduction heat of insulation seat (5) is made, can will be divided into many cells and spaced-apart to reduce the cross-ventilation amount to greatest extent in the cavity during design, the thickness of heat-insulation layer generally will reach more than the 40mm.Light-passing board on the insulation seat (3) is general with plate glass or other cheap transparent organic material goods, and the lighting space of heat build-up pipe is sealed.

The material of this downflow type solar water heater, be that indispensable high-order water storage tank is to heat build-up Guan Junwu specific (special) requirements from rural area at no running water, adopt general metal material to get final product, thereby cost is extremely low, Heat-collecting effect is satisfactory, and average water temperature can reach 40-50 ℃ under common intensity of sunshine.
