Description

[Detailed description of the invention] This invention is concerned with a fixing device for a filter that is arranged opposite to the air inlet surface of a plate-fin type heat exchanger. The purpose is to allow the filter to be easily installed and removed without coming into contact with the filter.

An embodiment of the present invention will be explained below with reference to the drawings. 1 shown in FIGS. 1 and 2 is a plate-fin type heat exchanger such as a condenser, which is made up of a plurality of metal plates arranged in parallel at equal intervals. a substantially U-shaped metal cover 3 which covers the upper surface and both right and left sides of the fin and which also serves as a tube plate and which has a flange 3a with a hole 4 at the bottom of both left and right sides, and the fin and the cover. It is configured by a plurality of metal refrigerant conduits 5 that perpendicularly pass through the side portions of the refrigerant pipes.

This heat exchanger is attached to the bottom plate of a machine room (not shown) by screws 6 inserted into holes 4.

Reference numeral 7 denotes a filter disposed in front of the air inlet surface with a slight gap from the air inlet surface of the heat exchanger, and a rigid frame member 8 having a rectangular shape with a dimension larger than the outer circumference of the air inlet surface.
and a net-like member 9 whose end face is fixed to this frame member.

10 is a fixing device that removably holds the filter 7 disposed on the front surface of the heat exchanger 1, and as shown in FIG. A U-shaped raised part 11 facing toward the rear, two receiving parts 12A and 12B arranged parallel to each other rearward from both lower ends of the raised part and receiving the lower end of the filter 7, and two receiving parts 12A and 12B extending from both receiving parts to open in the front direction. Both U-shaped mounting portions 13A and 13B are collinear with the flange 3A of the cover 3 and the bottom plate of the machine room by screws 6, and both inclined portions 14A extend upward from the mounting portions in a direction that intersects with each other. , 14B
and U-shaped clamping parts 15A and 15B that open inwardly from both bottom line parts and press and clamp both sides of the filter 7 by the elasticity of both inclined parts, and from one of the clamping parts 15B. A handle 16 extending outward is integrally formed.

According to such a fixing device 10, by using the elasticity of one cheek part 14B to pull this inclined part in the direction of the arrow in FIG. Clamping part 15A.

The side part of the filter 7 can be stored in the side part 15A, and when the holding part 15B is released, the filter 7 can be automatically pressed and held by the elasticity of the similar inclined parts 14A and 14B, and the holding parts 15A, 15B and the inclined part 14A , 14B can prevent contact between the filter 7 and the air inlet surface of the fin 2.

Further, the rising portion 11 and the receiving portions 12A and 12B can prevent the lower portion of the filter 7 from falling forward and also allow positioning.

Therefore, the filter 7 can be easily installed and removed by selecting from either the upward or forward direction, and furthermore, the filter 7 can be prevented from being damaged by pars on the air inlet surface, which is the cut surface of the fins 2.

Furthermore, the handle 16 allows the gap between the gripping portions 15A and 15B to be opened with less force.

As mentioned above, the present invention consists of bending a rod-shaped member several times to create a raised part that faces the lower front surface of the filter disposed on the air inlet surface of the plate-fin type heat exchanger, and a rear part from both lower ends of this raised part. both receiving parts extending to and receiving the lower part of the filter;
Both mounting portions extend in a U-shape from both receiving portions and are fixed to the heat exchanger, similar oblique portions extend diagonally upward from these two mounting portions in a direction that intersects with each other, and the inclined portions extend inwards from each other. Since it is integrally formed with both U-shaped clamping parts that are open in the direction and press and clamp both sides of the filter by the elasticity of the similar inclined parts, the filter can be attached and removed by the elasticity of the inclined parts. This can be easily done by selecting the upper part of the heat exchanger from the front, and also prevents damage to the filter by avoiding contact with the fins.Furthermore, the lower part of the filter can be positioned using the upright part and the receiving part, making it easier for the machine to A filter fixing device suitable for the shape of the room can be provided.
