Abstract

PURPOSE:To make it possible to hold the heat permeating rate at a large value by arranging a plurality of planar heat-exchange elements erected substantially in the vertical direction to the ground surface at a certain horizontal interval so as to form a heat exchanger, and disposing an air-flow collector having a top edge at the lower part of the heat exchanger. CONSTITUTION:A plurality of planar heat exchange elements 1 erected substantially in the vertical direction to the ground surface are arranged mutually at a certain horizontal interval thereby to form a heat exchanger 2, and an air-flow collector 3 having a channel shape and also having a top edge 4 in a direction perpendicular to the direction in which the heat exchange elements are arranged, is disposed at the lower part of the heat exchanger. In the collector constructed as described above, the heat permeating rate can be held at a large value by suitably moving the wind collector 3 and utilizing natural wind and natural convection. Thus, adverse effects due to dew condensation, rainwater and snowfall can be eliminated.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a heat collector that collects air heat using natural wind. Conventionally, in the case of this type of heat collector that uses air as a heat source,
In order to draw wind into the heat exchanger regardless of the wind direction, the heat exchange elements were placed horizontally and lined up at certain intervals.While this structure certainly has the advantage of being able to utilize the wind regardless of the wind direction, it also It has the following drawbacks: In other words, natural convection is difficult to occur. ■Difficult to remove water formed by condensation or rain on each heat exchange element. ■Receives snow load.

The present invention has been proposed to eliminate the above-mentioned drawbacks.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a perspective view of an embodiment, in which a heat exchanger 2 is formed by arranging a plurality of flat heat exchange elements 1 erected substantially perpendicularly to the ground with a certain horizontal spacing between them. At the bottom of the heat exchanger 2, there is arranged an air collector 6 which is mountain-shaped and has an apex 4 in a direction perpendicular to the direction in which the heat exchange elements 1 are arranged.

By the way, as shown in FIG. 4, each heat exchange element 1 has an inlet side header 5 for allowing a heat medium to flow in, and an outlet side header 6 for supplying a heat medium load (not shown) that absorbs air heat. is connected.

In the above configuration, when the heat exchange elements 1 are arranged as shown in the figure, if there is no air collector filter, it is possible to take in the wind in the χ direction, but in the case of the wind in the y direction, the heat exchange elements Since it is not possible to pass between 10 and 10, the heat transfer rate becomes low. If the fan 6 is placed below the heat exchanger 2, the air hits the fan 6, is pushed upward, and passes between the heat exchange elements 10, as shown in Figure 2. This increases the heat transfer rate. If the fan filter is placed in a symmetrical position with respect to the heat exchanger 2 in the direction in which the wind blows, it can be used regardless of whether the wind blows from either the left or the right with respect to the top ridge 4 of the fan filter, but the wind from one direction is especially Under conditions where there is a large amount of
By moving the air to the direction where the most wind blows, it is possible to blow air to all the heat exchange elements 1, and as a result, the heat transfer rate is lower than that of the embodiments shown in FIGS. 1 and 2. can also be made larger. In addition, when installing the heat collector according to the present invention, it is preferable that the wind direction in the winter when the outside temperature is low and heat collection is difficult to be in the χ direction in the figure. Of course, if the roof is not flat, but has a triangular shape, for example, the roof can be used instead of the ventilation filter. Although the heat exchanger 2 is of a flat plate type in the embodiment, it may be of any type such as a pipe-on-sheet type or a fin-chive type, and the heating medium circulation type can also be changed in various ways.

As described above, the heat collector according to the present invention can maintain a high heat transmission rate by utilizing natural wind and natural convection, and has excellent effects such as eliminating problems caused by dew condensation, rainwater, and snow accumulation.
