BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heat exchanger for collecting radiant heat from a heat source such as the sun and radiating unnecessary heat, and more particularly to a heat exchanger for use in a suspended state.

[0002]

2. Description of the Related Art Conventionally, pump-type solar collectors and the like which are installed and used in a plane are well known. These types of collectors are often inevitably installed on the roof to take up space.

[0003]

The problem of the present invention is that if a commercial heat collector is used, the area occupied by the heat collector is considerably large. I have. An object of the present invention is to solve the above-mentioned problems of the related art by providing a heat exchange device having a simple structure in which the entire heat exchange device is suspended and installed in a state where the heat exchange device is self-standing.

[0004]

A heat exchange apparatus according to the present invention comprises a load support installed on a support surface such as the ground surface, a holding member erected on the load support, and provided on the holding member. It is configured using a heat exchange sheet and a heat insulating sheet which are suspended using a suspending means and laid down with a space therebetween to form a space. The suspended heat exchange sheet and the heat insulating sheet are continuous in a loop. In the space, there is provided a heat medium liquid supply means for causing the heat medium liquid to adhere to and flow down on the back surface of the heat exchange sheet, and a lower part of the space is provided with a storage tank or a flow tank for storing the heat medium liquid flowing down. A road is formed. These storage tanks or flow paths can be formed by utilizing the depressions provided in the load support.

[0005]

With the construction described above, the weight of the main components of the heat exchange sheet and the heat insulation sheet is received by the holding member and transmitted to the load support, and these materials are subjected to a slight tensile force due to their own weight. It is stretched over and has no wrinkles. Therefore, the holding member bears the load of the structure, and no excessive stress is applied to the material.
The load support that supports the holding member can also serve as a weight, and a stable structure with a low center of gravity without a risk of falling can be obtained. In addition, since the heat exchanger is used in a suspended state, the occupied area can be greatly reduced as compared with the conventional one, and a highly versatile heat exchange device having no restriction on the installation location can be obtained.
