Abstract

PURPOSE:To uniform the flow of air, flowed through an element, and improve heat exchanging efficiency by a method wherein two sheets of partitioning plates are op posed along the whole surface thereof with an equal space to form an air flow path in the opposing space and a surface, connecting the inner and outer ends of the partitioning plate, is curved while a plurality of elements, having different lengths from the inner ends to the outer ends thereof, are arranged around a boss in a condi tion that the curved surfaces thereof are adhered to the neighboring curved surface. CONSTITUTION:The lengths from the inner end to the outer peripheral rim of a plural ity of elements including the elements 11, 11' are changed sequentially and the element is arranged in radial substantially so that the inner end thereof is located at the side of the circumferential surface of the boss 10 while the surfaces of the partitioning plates 12, 13 are adhered to the neighboring partitioning plates so as to constitute a true circle by the outer ends of respective elements. The space between two sheets of partitioning plates 12, 13 in respective elements 11, which is utilized as the flow path of air, is equal from the inner end to the outer end of the element 11, therefore, a pressure loss in the flow path of air becomes constant and the distribution of airflow, having different pressure loss, is eliminated, therefore, the heat exchanging efficiency may be improved.

Description

DETAILED DESCRIPTION OF THE INVENTION The industrial field of application relates to a stationary type p, 45 father exchange 6J which is combined with a ventilation system and which is used to recover exhaust heat. .

The structure of conventional chestnuts and their problems In general, when it comes to indoor air quality, it is 1. This will result in a breakage loss. Therefore, the chivalry device 6 is combined with a ρ air exchanger to heat the outdoor air that is taken in by the heat of the exhaust air.

As the heat exchanger, for example, a cylindrical heat exchanger as shown in FIGS. 6 and 7 is used. This cylindrical heat exchanger has r micro elements 1 arranged radially,
Primary air (exhaust) to adjacent elements 1a and 1b
A and secondary air (intake air) B are made to circulate, and the heat from the primary air is recovered to the secondary air B.

By the way, the element 1 is specifically arranged as shown in FIG.
3, and a corrugated spacer plate 4 interposed between the partition plates 2 and 3, and since they form a cylinder, the inner peripheral part 5
There is a difference in the width between the partition plate 2.3 and the outer peripheral part 6, that is, the partition plate 2.3
The flow paths +S and + in the axial direction of the circular segments formed between the two are narrow at the inner circumference and gradually become larger toward the outer circumference. In the figure, 7 is a vent provided on the back, 8, 9 is a ladle base 11 is a material. There is a large pressure loss near the inner periphery of the flow path of element 1, and the airflow does not flow uniformly in the flow path, resulting in heat exchange failure.

The purpose of this is to enable students to improve their skills.

The invention's (1゛4 rifJ purpose, circle 1 by Akira Kio;) type heat exchange '4ii is based on two partition plates that are spaced evenly over the entire surface and oriented χ/J, and the opposing spacing is is used as a ventilation flow path, and the part connecting the inner end and outer end of the partition sheet metal forms a curved element, and the element has a number of stages with different lengths from the inner end to the outer end, and the curved surface is connected to the adjacent Things and M' Ij
It is arranged on the outer periphery of the boss in the state of f, and the circle formed by the outer end of the valley element is formed into a perfect circle.

Due to this fs configuration, each element is radially around the outer circumference of the boss, and even if the adjacent elements are
Always, from the inner end of 6 Elenonoto to the Jl of the outer fuku part
It is possible to improve the heat exchange efficiency by eliminating the need for air currents, and also to improve the heat exchange efficiency by making the heat exchanger with a round circular shape. It is something that can be done.

The theory of giving to others 1p” The one blade of the present invention! Figures 1 to 3rJ
I will explain it first.

In the figure, 10 is a cylindrical boss serving as the axis, and 11 is a heat exchange element disposed on the outer periphery of the boss and forming a cylindrical body as a whole. ni said element 11
A corrugated spacer plate 14 is interposed between the two partition plates 12 and 13, and the two partition plates 12 and 13 are rotated at equal intervals as a whole, and form a circular arc connecting the inner end and the outer peripheral end. Said partition g
A closing member 16 is attached to the -J1 end of 12 and 13, and a music element 11' similarly formed on this partition plate 12 is placed, and this overlapped One side end of the element 11' and the closing member 15 form a vent hole 16 that extends around the outer periphery at a distance.

The surface of 13 is temporarily used as a can 7I'I as a partition between adjacent elements, and the structure is such that the circle formed by the outer end of the valley element is a perfect circle.

Note that the valley element 11... is the partition plate 12.1.
3 are equally spaced at both the inner and outer ends (!: na-), a gap is created between the inner end of each element 11 and the circumferential surface of the boss 10, and a gap is created at the outer end of each element 11. Next to I'g
: A stepped portion is formed with the gap and the stepped portion, and a caulking material 17 is applied to this gap and the stepped portion.

The above-mentioned 11゛4 cylindrical heat exchange tube has primary air and secondary η
The basic operation of distributing air to the main fort and exchanging heat is the same as that of the previous J model, but between the two partition plates 12 and 13 placed between the L and 6 elements 11. ni'A
Since N, that is, A and the air passage 11'1S are equal to rrHI-i from the inner part to the outer part of the element 11, the loss of pressure In in the air flow path is constant, and the air flow (1i disappears). The heat transfer rate is 1, and each element 11... is made into an arc shape, and the horizontal length is iJ"7)'+'l, so the outer circumferential surface You can make the circle inside the page.
