Abstract

The utility model provides a separated heat pipe solar water heater, which belongs to the field of solar energy application engineering. The separated heat pipe solar water heater is composed of a heat pipe collector, a heat pipe condenser, a water delivery pipe and a hot water storage tank. There is a detachable heat preservation cover, and the water pipe passes through the water inlet and outlet of the water jacket to send water into the hot water storage tank. Since the inner cavity volume of the outer water jacket of the heat pipe condenser is small, the water entering the water jacket is very small. It is heated quickly and sent to the water tank through the water pipe. The water heater can also be used for heating in winter. Since the condenser is not directly placed in the water tank, the hot water storage tank can be placed indoors, the heat pipe condenser can be placed indoors or outdoors according to needs, and the heat pipe collector can be placed on the south-facing balcony or under the window sill . The separated heat pipe solar water heater is convenient to install and use, and is suitable for all floors of modern high-rise buildings.

Description

The separate heat pipe solar water heater

Technical field: the utility model belongs to a kind of equipment that utilizes solar energy to convert heat energy in Application of Solar Energy engineering field, particularly a kind of separate heat pipe solar water heater.

Technical background: because the thermal conversion efficiency height of heat pipe is used on the solar water heater gradually.At present, use more general heat pipe solar energy water heater, form by heat pipe collector, heat pipe condenser and water tank, heat pipe condenser places water tank, by the heat energy in the heat pipe collector absorption solar energy, carry out heat exchange repeatedly by the water in heat pipe condenser and the water tank, make the progressively heating of water in the water tank.The heat collector of this water heater, condenser and water tank all are installed on outdoor.This solar water heater exists function singleness, can only supply water, can not heat, and, be unsuitable in the high-rise, in, the user's of lower floor use.

Technology contents: the purpose of this utility model provide a kind of not only can heat supply water, and the separate heat pipe solar water heater that can heat.

Separate heat pipe solar water heater provided by the utility model is made up of heat pipe collector 1, heat pipe condenser 2, water-supply-pipe 3 and heat storage water tank 4 etc., the outside that is characterized in described heat pipe condenser 2 is covered with an its corresponding water jacket 5 of inner chamber, also has a removable stay-warm case 6 in the outside of water jacket 5, water-supply-pipe 3 is sent water into heat storage water tank 4 through the water inlet 7 and the delivery port 8 of water jacket 5.

Separate heat pipe solar water heater operation principle provided by the utility model is as follows: the heat that is absorbed solar energy by heat pipe collector 1, working medium is subjected to thermal evaporation in the heat pipe, enter heat pipe condenser 2 through the defeated heat pipe of isothermal from advancing almost mouth 2.4, because there is water jacket 5 outside of heat pipe condenser 2, the heat that enters working substance steam in the heat pipe condenser 2 is absorbed by the water in the water jacket 5, steam state working medium liquefy, under the effect of gravity, flow back to heat pipe collector 1 from the liquid outlet 2.3 of heat pipe condenser, form thermal cycle, because the inner chamber of heat pipe condenser 2 outside water jackets 5 and heat pipe condenser is big or small corresponding, volume is less, carrying out being heated very soon after the heat exchange with heat pipe condenser so enter the water of water jacket 5, the coolant-temperature gage that comes out from water jacket more than 50 ℃, is sent into water tank through water-supply-pipe at least.This detachable solar water heater also can be used to heat winter, because the outside of water jacket 5 also has a removable stay-warm case 6, when being used to heat, the stay-warm case 6 of water jacket 5 outsides is removed, water in the heat pipe condenser 2 outside water jackets 5 just can carry out heat exchange by the cold air in the water jacket and the external world, and room air is heated.When being used for heat supply water, stay-warm case 6 is enclosed within the outside of water jacket 5, not only can keep the temperature of water in the water jacket 5, the heat that also can prevent water in the water-baffling sleeve is to indoor diffusion.This separate heat pipe solar water heater is not because condenser is directly to place in the water tank water is heated, heat storage water tank can be placed in indoor, heat pipe condenser can be placed on indoor as required, also can be placed on outdoor, heat pipe collector can be placed on the balcony in south, also can be installed under the windowsill in southern room.This separate heat pipe solar water heater is installed, uses all more convenient, is suitable for each floor room of modern high-rise building thing and uses.

The advantage of separate heat pipe solar water heater provided by the utility model is: have the function of heat supply water and heating simultaneously concurrently, and installation, easy to use is suitable for each floor room of modern high-rise building thing and uses.

Figure of description:

1, the utility model provides the structural representation of separate heat pipe solar water heater embodiment one;

2, the longitudinal cross-section schematic diagram of the outer stay-warm case of water jacket among the utility model embodiment one;

3, the utility model provides the structural representation of heat pipe condenser among the separate heat pipe solar water heater embodiment two and outside water jacket thereof.

Embodiment: below in conjunction with description of drawings enforcement of the present utility model.Fig. 1 provides the structural representation of detachable solar water heater embodiment one for the utility model.What heat pipe collector 1 adopted as can be seen from Figure 1 is flat type solar heat collector, the two ends up and down that it will form all single heat pipe evaporator sections of heat collector are communicated with respectively with pipe, the heat pipe outside has heat absorption fin, heat pipe collector to be placed in the lighting heat preserving casing piece of surface covering glass.Heat pipe condenser 2 is a heat pipe condenser pipe 2.1 straight, tyre spiral heat dissipation sheet 2.2, heat pipe, heat absorption fin and the spiral heat dissipation sheet of forming heat collector and condenser, can adopt copper, aluminium or steel to make, form the heat pipe of heat collector and the outside of radiating fin and scribble heat-absorbing material.Water jacket 5 covers on the outside of heat pipe condenser 2 just, its inner chamber is slightly larger than the volume of heat pipe condenser, the water inlet 7 of water jacket 5 and delivery port 8 are located at the two ends of water jacket, and the liquid outlet 2.3 on water inlet 7 and the condenser 2 is at an end of water jacket, and the air intake 2.4 of delivery port 8 and condenser 2 is at the other end of water jacket.Water-supply-pipe 3 is through the water inlet 7 and the delivery port 8 of water jacket 5, water is sent into heat storage water tank 4, at the bottom of the case that also has a branch branching pipe 3.1 and heat storage water tank 4 on the water-supply-pipe 3 of water inlet 7 one sides, join in the present embodiment, by valve 10 or the water-supply-pipe 3 of valve 11 control water inlets 7 one sides or the on-off of branch branching pipe 3.1.Water jacket 5 adopts stainless sheet steel to make, and heat pipe collector and heat pipe condenser adopt removable interface tube 9 to be tightly connected.The removable stay-warm case in water jacket 5 outsides adopts polyurethane foam plastic to make, and the two parts that constitute stay-warm case as can be seen from Figure 2 intermesh.Water tank 4 adopts corrosion resistant plate to make, and there is the polyurethane foam plastic thermal insulation layer outside, and water-supply-pipe 3 adopts galvanized pipe.
