Description

  The present invention relates to a heat exchanger that transfers heat using a heat pipe and a floor cooling / heating device using the heat exchanger.

Conventionally, as a heat exchanger using a heat pipe, a heat exchanger having a header portion having a heat source portion at an end portion of the heat pipe has been developed.
As one having such a heat exchanger, for example, (Patent Document 1) discloses “a heat panel in which a heat pipe is provided along a panel body and header portions each having a heat source part are provided on both sides of the heat pipe”. ing.
(Patent Document 2) includes "a plurality of heat radiating and aggregating parts arranged in parallel on a panel body made of concrete, and an evaporation part header that is connected to these and through which a heat medium flow pipe penetrates. A concrete panel for melting snow is disclosed.
Japanese Examined Patent Publication No.59-43712 JP-A-60-233204

However, the above conventional techniques have the following problems.
(1) The heat panel disclosed in (Patent Document 1) is manufactured by integrating a heat source portion such as a hot water pipe and an electric heater in a header portion communicating with a heat pipe. In addition, the concrete panel disclosed in (Patent Document 2) is manufactured by being integrated with an evaporation section header (header section) connected to the heat radiation aggregation section through a heat medium flow pipe (heat source section). The heat pipe communicating with the header portion needs to be completely sealed in order to depressurize the inside and enclose a working fluid such as a refrigerant. However, in the technique described in (Patent Literature 1) and (Patent Literature 2), Since the heat source part is penetrated and integrated, it is necessary not only to completely seal the header part and the heat pipe, but also to completely seal the header part and the heat source part. For this reason, when manufacturing, in addition to sealing the header portion and the heat pipe, it is necessary to also seal the header portion and the heat source portion, which requires man-hours and is difficult to increase productivity. Had.
(2) Since the heat source part is divided for each panel, when the panel is spread on the floor and used as a floor heating device, if the hot water pipe is used as the heat source part, the hot water pipe divided for each panel is welded or jointed, etc. It was necessary to connect with, and had the subject that lack of workability. In addition, since the hot water pipes are connected by welding, joints, or the like, there is a problem that the flow of hot water is disturbed at the joints of the hot water pipes, resistance increases, and pressure loss increases.
(3) Since the header and heat pipe and heat source are integrated into a panel, the heat source such as a hot water pipe is clogged with rust or scale, or the heat source such as an electric heater is disconnected Since only the heat source part cannot be exchanged, the header part and the heat pipe must be exchanged together with the panel, and there is a problem that maintenance is lacking and a large number of exchange man-hours are required.

The present invention solves the above-mentioned conventional problems, and it is not necessary to integrate the header part and the heat source part, such as passing the heat source part through the header part, and sealing the header part and the heat source part. Work can be saved and productivity is excellent, and long continuous hot water pipes can be used as the heat source part.Therefore, it is not necessary to connect the heat source part by welding or joints. Therefore, the resistance of the fluid flowing through the piping is low, the pressure loss can be reduced, the load of the fluid circulation device such as the hot water circulation device can be reduced, and the header part and the heat source part are not integrated. If the heat source is rusted or clogged due to a failure or if it is disconnected, only the heat source can be replaced without replacing the heat exchanger. And to provide a heat exchanger.
In addition, the present invention eliminates the need for connecting the heat source by welding, joints, etc. after laying the heat exchanger on the floor, and is excellent in workability, and because there are few joints, the resistance of the fluid flowing through the piping is low and the pressure loss Therefore, if there is an abnormality in the heat source unit, only the heat source unit can be replaced without replacing the heat exchanger.

Thereby, the enclosed hydraulic fluid can be evaporated from the header portion and moved to the heat pipe portion to dissipate heat. For this reason, there is no need to integrate the header part and the heat source part such as passing the heat source part through the header part, and only the header part and the heat pipe part are sealed when the heat exchanger is manufactured. The sealing work between the header part and the heat source part can be omitted, and the productivity can be improved.
