Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a floor panel used for heating general houses or large-scale buildings, or for melting snow on sidewalks, parking lots, etc.

[Prior Art] Floor heating using radiant heat has been widely known as an environmentally friendly and efficient heating system, and various systems have been proposed. In this method, a meandering thermal fluid path is provided in a plate-shaped heat insulating material having a predetermined size, and hot water is circulated within this thermal fluid path to heat a heat sink disposed on the surface of the thermal fluid path. It is configured to transmit heat and radiate the heat into the room from this heat sink.

However, this floor panel is constructed to focus on heat dissipation into the room, and in order to prevent heat dissipation to the underfloor, a heat insulating material such as highly insulating hard urethane foam is placed on the underside of the thermal fluid path. Therefore, when the operation of a heating device such as a boiler that supplies hot water to the thermal fluid path is stopped, residual heat in the thermal fluid path is immediately dissipated, causing the problem that the floor panel immediately becomes cold. In order to solve these problems, the applicant first formed a panel of a predetermined area using an inorganic material material with heat retention and heat storage properties, such as concrete, instead of using a heat insulating material. A tube 1 water is integrally fixed to a trough provided on the upper surface to form a thermal fluid path, and heat is radiated into the room from a metal heat sink disposed on the upper surface side of this thermal fluid path, Utility Model 62-777 developed a floor heat panel that is less likely to cool down even when the heat source supply is stopped and has good heating efficiency by forming the panel with concrete that has heat retention and heat storage properties instead of heat insulating material.
This is proposed in Publication No. 11.

[Problems to be Solved by the Invention] However, in the conventional example, the panels are joined and assembled one by one according to the floor area, and both ends of the pipe provided in each panel are joined. Although it is configured to form a predetermined heat dissipation panel and a thermal fluid path, since the tube body is provided integrally with the panel, the thermal fluid path formed by joining both ends of each tube body is The shape is inevitably limited and cannot be set freely, and the tube body is mainly made of copper, and both ends of the tube body are joined by brazing welding. However, depending on the floor space, multiple panels would have to be installed, which would increase the number of welded pipes, making the piping work cumbersome.
In addition, cracks may form at the welded parts due to aging or corrosion, resulting in poor durability and reliability.In addition, metal heat sinks are installed on the surface of the panel for heat dissipation. Therefore, considering corrosion and durability, there is a problem that it is limited to indoor floor heating.

Therefore, the present invention makes it possible to freely select the thermal fluid path and to attach a seamless integral pipe body to the panel.
Not only can the piping work be simplified and construction can be simplified, but it can also improve durability against aging and long-term use.
Furthermore, it is an object of the present invention to provide a heat panel that can be used in any environment, whether indoors or outdoors.

[Means for Solving the Problems] The present invention provides grooves 2 on the upper surface of a panel 1 that is divided into a plurality of parts, attaches a flexible tube body 3 to the grooves 2, and connects the grooves 2 with the grooves 2. The tubular body 3 constitutes a thermal fluid path 5 in which a heat medium 6 is circulated.

[Function] When a plurality of panels are selectively combined, the grooves provided on the panels are appropriately selected and formed, and when a tube body serving as a thermal fluid path is installed in the grooves, a flexible tube is formed. The body is tightly fitted within the groove, and the heat of the heat medium circulating within the tube is transferred to the panel via the tube.
