JPS5925132B2 - Heat dissipation equipment around foundations in low-temperature buildings - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a heat dissipation device for a foundation in a low-temperature building such as an ultra-low temperature refrigerated warehouse using an external heat insulation method.

Conventionally, in this type of equipment, the methods of providing sufficient heat dissipation space around the foundation of the low-temperature building or burying heat dissipation pipes such as Huum tubes have been used, but there are efficiency issues and
It could not be said that reliability at ultra-low temperatures was sufficient.

The present invention has been proposed in view of these circumstances, and includes arranging radiation fins facing the outer peripheral air layer around the foundation 9 of a low-temperature building, and installing a radiation bridge connecting the radiation fins around the foundation. This relates to a heat dissipation device around the foundation of a low-temperature building, which is characterized by being buried in the ground, and its purpose is to efficiently dissipate heat around the foundation of a low-temperature building and prevent frost heaving of the structure. At the point.

As described above, in the present invention, heat that is unnecessary or harmful to the building is efficiently transferred to the atmosphere by arranging heat dissipation fins facing the outer peripheral air layer on the foundation of the low-temperature building. (It dissipates heat and effectively prevents frost heaving.

Furthermore, in the present invention, by burying a heat radiation bridge connecting the heat radiation fins in the foundation, efficient heat radiation to the cross section of the foundation is impeded.

The present invention is an effective and economical heat dissipation device particularly for ultra-low temperature refrigerated warehouses using an external heat insulation method.Although the present invention is based on natural heat dissipation into the atmosphere, it may be combined with strong ventilation or with an appropriate It is conceivable to use a container together with a circulation system using a medium other than air.

The present invention will be described below with reference to the illustrated embodiments.

1 is a floor slab of a low-temperature building, 2 is a foundation pile, 3 is a heat insulating layer made of polystyrene foam, etc. layered on the bottom surface of the floor slab 1, and 5 is a heat insulating layer formed between the heat insulating layer 3 and the ground 4. This is an air layer.

Radiation fins 6 made of metal or the like with high thermal conductivity are attached to the outer periphery of the foundation pile 2, facing the air layer 5, and inside the foundation pile 2 is a radiation bridge 7 that connects the radiation fins 6. 〃He is being forced to play a hard role.

The heat dissipation bridge 7 is made of a metal or the like having high thermal conductivity, and is made of a piece of wire mesh or the like so as not to interfere with the reinforcement of the foundation pile 2.

Therefore, heat that is unnecessary or harmful to the building is efficiently radiated into the atmosphere by the radiation fins 6, and frost heave is effectively prevented.

Furthermore, the heat dissipation bridge 7 is used to efficiently dissipate heat to the cross section of the foundation pile 2.

Note that, as shown in 8 in the figure, the radiation fins 6 may be surrounded by a medium circulation container such as antifreeze solution, and the heat radiated from the radiation fins 6 may be efficiently radiated by the medium flowing in the container 8.

Although the present invention has been described above with reference to embodiments, the invention is not limited to such embodiments (and various modifications may be made to the design without departing from the spirit of the present invention). be.
