Abstract

Conventional heat pipes are mostly straight and require a heat transfer head when heating piping. Therefore, when the heating average is wide, dozens of heat transfer heads are required for each of the dozen straight heat pipes, and thus the number of construction hours is increased. Especially, when the hot water flow is curved inside the heat transfer head, The flow of metal is not smooth and the mold manufacturing cost is high, the injection manufacturing cost is high, and the subsidiary materials such as packing are used to assemble the heat pipe and the heat transfer head. Labor costs are increased, and there is a problem that the incidence of poor construction due to the increased confidentiality. The present invention is characterized in that the heat transfer head is formed of an integral material at one end of the heat pipe, so that the pipe can be connected to the hot water heating heat dissipation tube without using a separate heat transfer head. It is to provide a heat transfer head-integrated heat pipe with a good flow chart of hot water, in order to reduce the construction cost according to the parts manufacturing cost and construction.

Description

Heat pipe integrated heat pipe {heat pipe with heat transfer head}

The present invention relates to a heat pipe, and more particularly to a head-integrated heat pipe is provided with a heat transfer head integrally at one end of the heat pipe.

As is known, the heat pipe has a heat exchanger (working fluid) in the vacuumed pipe to have a rapid heat exchange action.

The heat pipe is used for heating and other various heat exchange members, and recently, it is widely used as a heat radiating tube to be buried in the floor in an ondol heating.

Most heat pipes provided in the prior art have a straight pipe shape.

Therefore, a separate heat transfer head is necessarily required in order to use a conventional straight heat pipe to pipe the heating heating tube of the ondol heating system.

The heat transfer head is a material for piping heat to the heat radiating pipe while transferring heat from a heating device such as a boiler to a heat pipe, and is a Korean Patent Publication No. 1999-80858, a Korean Utility Model Publication No. 2000-16253, 2000-16254 and It is disclosed in prior inventions, such as domestic utility model registration No. 218070.

FIG. 5 shows an example of a hot water ondol heating system using a conventional straight heat pipe, and FIG. 6 shows an enlarged view of an assembled state of an example heat transfer head connecting heat to a conventional straight heat pipe.

As shown, in the example of the hot water ondol heating system 50 using the conventional flat heat pipe 40 as the hot water ondol heating heat dissipation tube, several flat heat pipes 40 are arranged on the floor of the heating unit at an appropriate interval in parallel. After piping, one end of these several straight heat pipes 40 is connected to the boiler 47 and the hot water circulation pipe by using the heat transfer head 41, respectively.

Connection of the straight heat pipe 40 and the heat transfer head 41, after inserting the fasteners 42 and the packing 43 at the upper end of the body of the heat transfer head 41, one side of the straight heat pipe 40, The fastener 42 is screwed to the upper end of the heat transfer head 40 so that a part of the lower end of the heat pipe 40 is installed in the body of the heat transfer head 41 in an airtight state.

The heat transfer heads 41 installed on the lower portion of the heat pipe 40 connected as described above are connected to and installed in series. That is, the upper hot water pipe connector 44 attached to one side of the body of the first heat transfer head 41 is connected to the hot water supply pipe 48 of the boiler 47, and the second heat transfer head to the lower hot water pipe connector 45. After connecting a plurality of zigzag up and down in such a way as to connect the lower hot water pipe connector 45 and the connector 46 of the 41, the upper hot water pipe connector 44 of the last heat transfer head 41 is a boiler ( 47 is configured to connect with the hot water return pipe (49).

As described above, the conventional straight heat pipe 40 is piped to the hot water ondol heating radiator using the heat transfer head 41, and in the case of a large heating scale, dozens of straight heat pipes 40 are provided for each of the tens of straight heat pipes 40. There was a problem that the heat transfer head 41 takes place, and thus the number of construction hours is increased, and in particular, when the hot water flow is curved in the inside of the heat transfer head, the hot water flow is not smooth.

In addition, as disclosed in the prior inventions, the heat transfer heads are synthetic resin injection parts, which are mostly manufactured as separate injection molds, and have a high mold production cost, a high injection production cost, and packing to heat pipe and heat transfer head assembly. By using the subsidiary materials, the construction cost is not only high, but also the labor cost is increased, the confidentiality is increased, the rate of construction failure increases.

In addition, since the lower part of the heat pipe is inserted into the heat transfer head and the heat medium is large, the hot water heating effect acting on the heat medium filled inside has a disadvantage of being made at a relatively high temperature of about 50 degrees Celsius.

In addition, when the heating means uses an electric heating element in addition to the hot water boiler, there is a disadvantage in that the construction cost and the number of construction times are increased because one electric heating element must be used for each heat pipe.

The present invention was developed in view of the conventional problems as described above, the object of the present invention is to form a heat transfer head integrally at one end of the heat pipe, a hot water heating radiator tube without using a separate heat transfer head It is characterized in that the piping is possible, to reduce the overall manufacturing cost according to the use of the heat transfer head parts and construction, and to provide a heat transfer head-integrated heat pipe with a good flow of hot water.
