Abstract

PURPOSE:To improve the heat exchanging efficiency by disposing multiple fine tubular heat exchanging elements in a pair of sirocco fans parallelly to the rotational axis, said elements extending from the outer side of one of the sirocco fans to the interior of the other sirocco fan. CONSTITUTION:By rotating a heat exchanging unit relative to its rotational axis 12 in order to perform heat exchanging and utilize the function of vanes 5, air masses having different temperatures are introduced to the interior of the opposing sirocco fan from the outer sides 2, 3 of the respective sirocco fans 1a, 1b through fine tubular heat exchanging elements 8, 11 which are disposed parallelly to the rotational axis 12. In this process, the air masses existing inside and outside the tubular heat exchanging elements 8, 11 at different temperatures exchange heat, and forced out in the direction of the centrifugal force by the vanes 5 located at the outer perimeter of the heat exchanging unit. Therefore, a single heat exchanging unit can also have the function of the vane. As a result, the surface area of the heat exchanging element can be enlarged without changing the size of the heat exchanging unit, and as the vanes and heat exchanging elements can be installed separately, the air flow rate can be increased.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention is installed inside an air conditioning ventilation fan or the like to exhaust indoor air and take in outdoor air having a temperature difference from the above air. This relates to a heat exchanger that exchanges heat between them, exhausts only the dirty air indoors, and recovers thermal energy.

BACKGROUND OF THE INVENTION Conventionally, heat exchangers such as air conditioning ventilation fans of this type have been provided separately from the blades, and there has been a demand for a system in which the blades and the heat exchanger are integrated.

For this reason, in the conventional heat exchanger, as shown in FIG.
The heat exchanger is provided in a radial manner in the direction of rotation, and air is taken in from each outer surface 104 by utilizing the pressure generated in the centrifugal force direction 103 by rotating it, and exhausted to the rotating surface 105. In the process, the heat exchange is performed. Heat exchange was performed through the element 101, and it also functioned as a blade. The flat heat exchange element 1 has a structure in which a plurality of plate members are stacked with a small gap between them, and the small gap is used as a ventilation path to exchange heat with an adjacent ventilation path. (For example, JP-A No. 6
8-193086) Problems to be Solved by the Invention In the conventional heat exchanger described above, in order to increase the surface area of the heat exchange element in order to improve the heat exchange efficiency, it is necessary to increase the surface area in the outer circumferential direction or to increase the length. must be increased in the direction, and
Since the heat exchange element itself replaced the blade, there was a problem in that the air volume was smaller than that of a device that had separate blades and heat exchange elements.

The present invention takes into consideration the above-mentioned conventional problems, increases the surface area of the heat exchange element without changing the size of the heat exchange body, improves the heat exchange efficiency, and improves the air volume by making the blades different from the heat exchange elements. The object of the present invention is to provide a heat exchanger which is equivalent to having blades and heat exchange elements separately by separately providing the same.

Means for Solving the Problems In order to achieve the above object, the present invention provides a plurality of thin tubular heat exchangers in a pair of left and right scirocco fans that communicate from the outer surface of one scirocco fan to the inner surface of the other scirocco fan. The element is arranged parallel to the rotation axis.

Function: In order to perform heat exchange and function as a blade with the above configuration, the heat exchange body with the above configuration is rotated about the rotation axis to transfer air having a different temperature from the outer surface of each sirocco fan to each other. The air is guided through the inside of a thin tubular heat exchange element that is provided inside the other sirocco fan parallel to the rotation axis, and in the process, the air that has a temperature difference between the inside and outside of the tubular heat exchange element is heat exchanged. The heat exchanger is sent out in the direction of centrifugal force by the blades on the outer periphery of the heat exchanger, making it possible for one heat exchanger to have the function of a blade.

EXAMPLE An example of the present invention will be described below with reference to FIG.

In the figure, 1 has outer plates 2 and 3 on both sides, and a partition plate 4.
are provided between the outer plates 2 and 3, and blades 5 are provided between the outer plates 2 and 3 and the partition plate 4 to form a pair of left and right sirocco fan parts 1.
a, 1b A fully constructed sirocco fan structure. This sirocco fan structure 1 has a space between one outer plate 2 and a partition plate 4, and a space 7 between the other outer plate 3 and the partition plate 4. A thin tubular heat exchange element 8 is provided between the outer plate 2 and the partition plate 4 to connect the space 9 outside the outer plate 2 and the space 7. A thin tubular heat exchange element 11 is provided to connect the space 1Q outside the outer plate 3 and the space 6. A plurality of heat exchange elements 8 and 11 are provided parallel to the rotating shaft 12.

In the above configuration, by rotating the pair of left and right sirocco fan components 1 about the rotating shaft 12, the air 13 is transferred from the space 9 through the inside of the heat exchange element 8 to the space 7 and to the direction of the direction of force of the sirocco fan 16. 15, similarly air 1
4 is sent from the space 10 through the interior of the heat exchange element 11 to the space 6 and in the centrifugal force direction 16 of the sirocco fan 1a. If air 13 and air 14 have a different temperature, for example, air 14 has a higher temperature than air 13, heat will be transferred to air 13 from air 14 through the heat exchange element by space 6 and space 7. They are heated and discharged in the centrifugal force directions 15 and 16 of the sirocco fans 1a and 1b, respectively.

As described above, according to this embodiment, the outer plates 2, 3, the partition plate 4, and the plurality of thin tubular heat exchange elements 8, 11 are arranged inside the pair of sirocco fans 1a, 1b to form the outer plate holes 3. By connecting the spaces 6, 7 created by the partition plate 4 and the spaces 10, 9 outside the outer plates 2, 3, and rotating about the rotating shaft 12, one heat exchange body has the function of a blade. be able to.

As is clear from the description of the embodiments above, according to the present invention, one of the scirocco fans in a pair of scirocco fans is
゛ Equipped with a plurality of thin tubular heat exchange elements parallel to the rotation axis that communicate from the outer surface to the inner surface of the other scirocco fan, and by rotating the scirocco fan, air having a different temperature is transferred to the other scirocco fan. From the outside surface, each guides into the other sirocco fan,
A heat exchange body that exchanges heat through the tubular heat exchange element in the process and has the function of a blade,
Up until now, the blades and the heat exchanger had to be constructed separately, but the effect of having them function as one is great.
