Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a heat exchanger used in an air conditioner ventilation fan or the like in an interior state.

[Conventional technology]

FIG. 4 is a perspective view showing a conventional heat exchanger of this type disclosed in Japanese Utility Model Laid-Open No. 59-23589, in which (11) is an integrated body of heat exchange elements stacked in a rectangular column shape, 12) is a top plate for holding the integrated body (11) in the interior state, and (13) has one end fixed to the top plate, and the integrated body (1
Four outer peripheral protection bars for individually protecting each ridge line portion on the outer periphery of 1), and the other ends thereof are fixed to the bottom plate (14) brought into contact with the bottom surface of the above-mentioned integrated body (1). Further, (15) is a carry-out handle fixed to the top plate (12).

[Problems to be solved by the invention]

Since the conventional heat exchanger is configured as described above, four protection bars (13) are required to protect each ridge line portion on the outer periphery of the integrated body (11), and therefore these and the integrated body are integrated. There is a problem that a lot of labor is required for the sealing work for preventing the mixing of the primary air flow and the secondary air flow in the assembled state.

An object of the present invention is to construct a so-called outer protection frame for protecting each ridge line portion on the outer circumference of the aggregate so as to solve the above-mentioned problems from a wound body of a single strip plate.

[Means for solving problems]

In the case of this invention, the outer protection frame for protecting each ridge line portion on the outer periphery of the integrated body of heat exchange elements is composed of a single strip-shaped plate winding body having a ventilation hole on each bent surface, and
In the predetermined winding state of the aggregate by the outer protective frame,
The inner surface of each bent portion of the outer protective frame that abuts each ridgeline portion on the outer periphery of the aggregate has 1
A sealant that prevents mixing of the secondary air flow and the secondary air flow is previously applied.

[Action]

In the case of this invention, by simply wrapping a band-shaped outer protective frame having ventilation holes on each bent surface around the aggregate, protection of each ridge line portion on the outer periphery and sealing of the ridge line portion can be performed at once.

〔Example〕

An embodiment of the heat exchanger of the present invention will be described below.
That is, in FIG. 1, FIG. 2, and FIG. 3, (1) is a laminate of heat exchange elements laminated in a square pole shape, and (2) is an outer protection of a wound body enclosing the laminate (1). A frame, which is composed of a single strip-shaped plate, is formed such that each bent portion (2a) thereof is in close contact with each ridge line portion (1a) on the outer periphery of the above-mentioned integrated body (1) in a rolled state, and Vent holes (2b) for the primary air flow and the secondary air flow are opened on each bent surface. (3) is a sealant that is present between the stacking surface of the above-mentioned assembly (1) and the outer protective frame (2) in the assembled state to prevent mixing of the primary air flow and the secondary air flow in the portion. This is previously attached to the inner side surface of each bent portion (2a) of the outer protective frame (2).

Fig. 1 shows the disassembled state of the heat exchanger of this invention.
FIG. 3 is a plan view showing a state in which the outer protective frame (2) is being wound around the aggregate (1) in a cross-sectional state of the outer protective frame. Each bent portion of the outer protective frame (2) ( The inner surface of 2a) shows a state in which the above-mentioned sealant (3) has been applied in advance as shown in the figure.

[Effect of device]

Since the heat exchanger of the present invention is configured as described above, by simply winding the outer protective frame in the form of a single band in which the sealant is applied to the inner surface of each bent portion around the aggregate, This has an effect that protection of each ridge line portion on the outer periphery of the aggregate and sealing of the portion are completed at once.

FIG. 4 is a plan view showing a state, and FIG. 4 is a perspective view showing a conventional heat exchanger. In the figure, (1) is a stack, (1a) is a ridge line part, (2) is an outer protective frame, (2a) is a bent part, (2b) is a vent hole, and (3).
Indicates a sealant.

Claims (1)

[Scope of utility model registration request] 1. An outer protective frame for a stack of heat exchange elements, which is laminated in the shape of a quadrangular prism, and an outer protective frame of the stack, which is composed of a rolled-up body of a single strip plate and has a ventilation hole in each folding surface. The sealant is applied in advance to the inner side surface of each bent portion of the outer protective frame that comes into contact with the ridge line portion of the outer periphery of the aggregate in a predetermined winding state by the protective frame. And a heat exchanger.
