09/09 '02 15:59 FAX 61 8 82126464 P.O.F ADELAIDE 005 .i r EVACUATED TUBE HEAT PIPE TRANSMITTER FOR A'SOLAR
COLLECTOR
The present invention relates to heat transmitters for securing an evacuated tube heat pipe into thermal connection with a pipe containing a working fluid into which heat is transferred. The heat transmitter of the present invention is particularly suitable for use in a solar heating and cooling system.
Background of the Invention It has been reported that the efficiency of evacuated .tube heat pipe solar collectors is higher than a more traditional flat panel solar collectors. In the former solar collectors (which are known), an evacuated tube heat pipe is heated by incident solar thermal radiation and the heat absorbed by the evacuated tube heat pipe is transferred by contact thermal transfer to a tube that carries a working fluid such as water. The working fluid is consequently heated and is then transferred to either to a heat storage vessel or a further heat transfer mechanism.
Despite the burgeoning use of solar collectors both industrially and domestically, there is still a relatively high initial capital cost involved and therefore there is always a need to manufacture solar collectors as cheaply as possible, but without compromising on the efficiency of the collector as a heater.
As an important component of a solar collector, there is a need for a heat transmitter that holds a heat pipe in thermal contact with a working fluid pipe and that is simple and inexpensive and that maximises thermal transfer between the evacuated tube heat pipe and the working fluid carrying pipe.
Summary of the Invention The present invention provides a heat transmitter for securing a heat pipe to a working fluid pine, the transmitter including a first shaped component having two or more channels wherein each channel can be fitted with a heat pipe. and 09/09 '02 15:59 FAX 61 8 82126464 P.O.F ADELAIDE 01006 2 a second shaped component having a channel into which a working fluid pipe fits, wherein the transmitter can be assembled so that the first and second shaped components are secured together and two or more heat pipes lie across the working fluid pipe and are in thermal contact therewith.
The second shaped component may also contain two or more channels into each of which a working fluid pipe can be fitted so when the heat transmitter isassembled, the two or more working fluid pipes are in thermal contact with the heat pipe.
Most preferably, both of the first and second shaped components contain two or more channels.
Brief Description of the Figures The invention will now be described with reference to the accompanying figures in which: Figure 1 is a plan view of an evacuated heat tube pipe and a first shaped component in a disassembled state (in the left of the figure), and in a fitted state (in the right of the figure) in which the heat pipe is fitted into a channel in the first shaped component; Figure 2 is a plan view of a working fluid pipe and a second shaped component in a disassembled state (in the left of the figure), and a fitted state (in the right of the figure) in which the working fluid pipe is fitted into a channel in the second shaped component; and Figure 3 is a plan view of the heat transmitter of the present innovation in an assembled state in which the first shaped component is 09/09 '02 16:00 FAX 61 8 82126464 P.0.F ADELAIDE 0j007 4~N assembled on top of the second shapdd compbonent-so that the heat pipe lies across the working fluid pipe.
Detailed Descriotion of the Invention Figure 1 shows an evacuated heat tube pipe of known type that is us-ed in solar collectors. The evacuated heat tube includes an evacuated tube which hasa heat pipe running therethrough. The evacuated tube is heated by solar* radiation and heat is transferred into the heat pipe Further details of evacuated heat tubes of this type can be found in Australian Patent Application No. AU-A-20032195.
in some known solar collectors, a tip of the heat pipe is placed -into the rmal contact with a working fluid pipe so that heat is transferred from the tip of theheat pipe into the working flid In the case of most s olar collectors, the workinig fluid is water and the heated water is then transferred to a storage tank where it is ready for use.
Typically, the solar collectors include a plurality of evacuated heat tibe- pipes arranged in a parallel configuration with respect to one another. The tip of each heat pipe abuts the working fluid pipe which runs transveysely across of the top of the heat pipes. A heat transmitter unlike that of the present invention is sometimes used to secure the heat pipes and the working fluid pipe with respect to one another.
The heat transmitter of the present invention is used for securing the heat pipe to the working fluid pipe in a configuration in which the heat pipe lies across the working fluid pipe. The heat transmitter includes a first shaped component that has a channel into which the heat pipe fits. As best seen in Figure 1, the first shaped component is fitted to that part of the exposed heat pipe that extends beyond the end of the evacuated tube The channel is 09/09 '02 16:00 FAX 61 8 82126464 P.O.F ADELAIDE U~008 4of a shape and size that it covers about halt of the surfa6e of the heat pipe (2) so that there is goad thermal contact between the two.
As best seen. in Figure 2, the second shaped component alsd has a channel .into which the working fluid pipe fits. Again, the channel is of a shape a nd size'that it covers about half of the surface of the working fluid pipe-(5)-so that there is good thermal contact between the two.
The heat transmitter is assertibled so that the first and second shaped components (3 and 4) are secured together and the working fluid pipe lies transversely across the tube heat pipe and is in thermnal contact therewith.
In that way heat is transferred from the heat pipe into the working fluid pipe and;'consequently, the working fluid.
As shown by the broken lines in Figures 1 and 2, both the first shaped component and the second shaped component may contain two or more channels into each of which the heat pipei and the working fluid pipe can respectively be fitted. In this way, when the heat transmitter is assembled, the two or more working fluid pipes are in thermal contact with the two or, more heatpipes.
The heat transmitter is made of material that is a thermal conductor, for example copper or aluminium. The first and second shaped components are connected together using any suitable fastening method or by welding. The assembled heat transmitter is then covered with insulation. Finally, the solar collector is assembled with frame, tubes, heat pipe and outer covering.
The embodiment has bedn described by way of example only and modifications within the spirit and scope of the invention are envisaged.
