Description

[Detailed description of the invention] This invention relates to fan-equipped devices such as radiators, and in particular aims to improve the workability and strength of fan installation for fan-equipped devices equipped with long fans such as axial fans. That is.

Generally, in this type of fan-equipped equipment, a fairly long fan is sometimes used in order to make the air outlet or air inlet as wide as possible.

In this case, the fan becomes weak against torsional force, and the number of attachment points to the housing increases.

As a result, the fan case or the housing to which it is attached must be made of a strong, thick plate, and as the number of mounting points increases, assembly becomes difficult and production costs increase. was there.

The present invention has been made in view of these points, and is intended to solve all of the above-mentioned conventional drawbacks at once.

One embodiment will be described below with reference to the drawings. 1 is a housing with an open front, 2 is a front plate covered on the front side of the housing 1, and has an air outlet 3 and an air inlet 4; The body 1 can be pulled out toward the front by hooking one's fingers through the recesses 5 provided on both upper sides of the body 1.

Reference numeral 6 indicates a heat exchanger disposed at an angle within the housing 1, and 7 indicates a filter disposed in front of the heat exchanger.

8 is a fan installed in the housing 1 at the bottom of the heat exchanger,
An elongated fan such as an axial fan is used, and the suction port 9a of the fan case 9 is arranged to face the air outlet 3 of the front plate 2.

As shown in FIGS. 3 and 4, the upper rear surface of the fan case 9 is provided with a rib 10 that protrudes outward over the entire lengthwise direction. It is fitted into the groove 11.

Also, a flange 12 is provided at the bottom of the suction port 9a of the fan case 9.
The flange 12 is fixed to the lower front surface of the housing 1 with screws 13.

In the figure, reference numeral 14 denotes a wind direction grill pivotally supported at the edge of the suction port of the fan case 9.

In the above configuration, the convex rib 1 provided on the fan case 9
0 and the groove 11 of the housing 1 into which the rib 10 is fitted improves the strength of the fan case 9 and the housing 1 itself.

The interaction between these two elements 10 and 11 through fitting improves their combined strength, resulting in sufficient durability against twisting and the like.

Furthermore, the fan case 9 is fixedly held on the housing 1 by fitting between the ribs 10 and the grooves 11, eliminating the need for fixing work with screws, etc., and the grooves 11 are provided over the entire rear surface of the housing. Therefore, even if there is some dimensional error (lateral dimensional error) in the installation position of the fan case 9, there is no possibility of a failure that the fan case 9 cannot be installed, and there is also the advantage that the end stop is improved.

Furthermore, in this embodiment, since the rib 10 of the fan case 9 is particularly provided at the upper part of the rear surface of the fan case, the fan case 9 can only be fixed at the front with screws, etc., making it possible to install from the front. This also has the advantage of improving maintainability.

In addition, even if only the front portion is fixed, there is an advantage that the fan case 9 can be securely fixed without causing any downward deviation as indicated by the arrow a in FIG. 3.

Although the ribs 10 in the above embodiments are described as being convex, they may be concave, and in this case, the grooves 11 may be convex.

As is clear from the above description of the embodiments, according to the present invention, the fan can be easily attached to the housing, the strength can be improved, and the production cost can be significantly reduced. It has great practical value, such as being able to make the width of the object wider.
