The specific embodiment

For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.

As shown in Figure 1, the whole heat collector course of work is: double-glass vacuum pipe 4 absorbs sunshine, the double-glass vacuum pipe passes to the attached fin 5 that conducts heat to the solar energy that absorbs, conduct heat attached fin 5 again the thermal-arrest bar portion of the heat transferred heat pipe 7 that absorbs, the thermal-arrest bar of heat pipe 7 is delivered to heat the condensation end of heat pipe 7 from thermal-arrest bar portion by the heat-conducting work medium in the heat pipe, heat pipe 7 condensation ends are heat transferred heat exchanger Heat-exchanging cup groove 9 inwalls, cold water advances (going out) mouth of a river end 10 from heat exchanger and enters in heat exchanger 1 cavity, cold water is in heat exchanger 1 cavity, by U-shaped Heat-exchanging cup groove 9 outer wall heat-shifts, heated water flows out from the other end of heat exchanger 1.

Wherein heat exchanger 1 adopts the design of indent plug-in pressure-bearing, and Fig. 2 is 1 structural representation of the heat exchanger in the solar thermal collector among Fig. 1, and Fig. 3 is a heat exchanger A-A profile among Fig. 2.As shown in Figure 3, the U-shaped Heat-exchanging cup groove 9 of heat exchanger 1 is an enlarging U-shaped cylindrical cup groove, and rim of a cup is bigger slightly than the cup body, makes things convenient for the insertion of heat pipe 7 like this and extracts.As shown in Figure 2, the 9 equidistant soldering and sealing arranged side by side of U-shaped Heat-exchanging cup groove are connected on the hollow cylinder heat exchanger tube, both sides are beaten simultaneously with one heart with the footpath circular hole before and after the heat exchanger tube pipe shaft, spacing equates between same side opening and the hole, pipe is stressed more even before and after the heat exchanger tube when punching, simple and reliable process, heat exchanger 1 have formed the fan-shaped hollow pipe of indent II that two ends are communicated with.During heat transfer, heat pipe 7 condensation ends conduct heat from crossing U-shaped heat exchanger cup groove 9 inwalls, cold water is in heat exchanger cavity, by U-shaped Heat-exchanging cup groove 9 outer wall heat-shifts, heat transfer process carries out in heat exchanger cavity inside, heat does not have extraneoas loss, so it is higher to get heating rate, makes the Heat-collecting effect rate of whole heat collector higher.

Because heat exchanger 1 adopts the design of indent plug-in, the assembling that can break easily of heat collector each several part, during transportation, each parts of heat collector packed and transported respectively get final product, when safeguarding, also can not influence system's operation even carry out maintenance work under the heat collector duty, directly extract the two glass tubes and the heat pipe that need maintenance, the two glass tubes and the heat pipe that more renew then get final product.Because heat exchanger 1 pipe shaft and U-shaped Heat-exchanging cup groove 9 are airtight welding,,, this design all becomes very easily simple so making the transportation of heat collector and safeguard so heat collector drainage can not occur.

As shown in Figure 2, heat exchange temperature induction tube 8 is welded on the pipe shaft of heat exchanger both sides.The temperature of the heat exchange temperature inductor 8 by detecting heat exchanger 1 two ends can know whether collecting efficiency and heat collector work is normal.

The attached fin 5 that conducts heat is left-right symmetry round metal cylindricality thin skin, body diameter is slightly less than double-glass vacuum pipe 4 internal diameters, height is less than double-glass vacuum pipe 4 height 10-15cm, attached fin 11 of left side heat transfer and the right attached fin 12 that conducts heat fasten during installation, insert in the double-glass vacuum pipe 4, heat pipe 7 is close to the attached fin centre bore 13 that conducts heat and is inserted the attached fin 5 that conducts heat, and has effectively utilized metal solid heat transfer ratio gas principle faster, has improved heat transfer efficiency greatly.If do not conduct heat attached fin in the thermal-arrest gas, the water under heating the same terms then needs the longer time, and heat transfer efficiency can reduce greatly.

More than show and described basic principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
