Frame structure for radiator fan

Abstract

The invention provides a kind of frame structure for radiator fan. The main specialty is the frame combined with the fan by using of arc clasps on the outer rim to inlay into the grooves in the inner loop of the radiator that makes the frame can be firmly connected to the radiator without any bolt-fixed element. Besides, for designing the folds in the frame bridge elements and spring laminations in the outer rim of inner loop to absorb the fan's vibration energy to prevent the fan falling off and reduce noise.

Description

FIELD OF THE INVENTION

[0001] The invention relates to a kind of frame structure for radiator fan. Especially, the combined frame of a fan which can be securely locked into a radiator without any of fixture element and can absorb the fan vibration energies by a designed of spring panels and folds in the frame for preventing the fan fallen off and for achieving a noise reduction.

BACKGROUND OF THE INVENTION

[0002] Accordingly, the fan and frame in a conventional radiator use by bolts or rivets to fasten, then, inlay them into a radiator as a whole. Because the frame is made of plastic, the screw threads inside boltholes can easily be damaged and become loosened when the radiator is dismantled and then reassembled, there a large amount of noises will be occurred due to this occasion, the fan's vibrations. Besides, this phenomenon also occurred for no vibration buffer, such as spring panels and folds, is been quipped on the frame to absorb fan vibration energies, which make more noising than others. On the other hand, by using bolts or rivets to assemble or dismantle is very time and labor consuming.

[0003] Hence, due to a mature experience, lots of careful researches and repeated tests and improvements in the field for many years, the inventor finally invents this new type of frame structure for radiator fan which can eliminate these defects in the existing products and for improving the said effects and performances.

SUMMARY OF THE INVENTION

[0004] The principle object of the invention is to provide a kind of frame structure for radiator fan by using a clasp on the frame of the fan's set to lock the groove in the inner loop of the radiator in every related joining section, for which the frame will be closely embedded on there. Thus, a prompt and easy assembling of the radiator can be done as well as any bolt-fixed element, such as bolts and rivets, is not needed for this matter.

[0005] Another object of the invention is to provide a kind of frame structure for radiator fan, where the folds are located on the bridge elements of the inner loop in the frame and spring panels are equipped on the outer rim of inner loop for absorbing the fan's vibration energies and, consequently, for reducing radiator's noises.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0013] As shown in the foregoing figures from I to 6, the invention consists of a fan (1), a frame (2) and a radiator (3). Let the rivet (A) penetrate from the bottom of the frame (2) through the piercing hole (20) of the frame (2) to reach the center hole (10) of the fan (1). The fan (1) and frame (2) shall be combined as a whole, then placed them into the radiator (3), of its specialties as follows. The three of arc-shaped protruding retaining clasps (22) are set on the periphery of round outer rim (21) of the frame (2) and the inner loop (23) and the inner loop of the outer rim (21) are connected by the three of bridge elements (24). Where the contact ends between every bridge element (24) and the inner loop (23) are those arc-shaped folds (241) and spring laminations (25) which been stretched out from every adjacent section of the two bridge elements (24) of the inner loop (23) respectively. For the spring laminations (25) are not connected with the outer rim (21), so every suspended section in fold (241) and spring lamination (25) can absorb internal and external vibration energies of the fan (2) for reducing noises.

[0014] As shown in FIG. 4, grooves (31) set on the inner loop of radiator (3) to correspond with the three retaining loop (22) of frame (2) and for inlaying the loops (22). Since that, the frame can be securely attached on the upper surface of the grooves in the radiator (3). As the fan (1) and frame (2) are mounted together into the radiator (3). For the round periphery of the frame (2) is attached on the inner loop of the radiator (3) which makes the assembled fan's (1) components can be firmly inlayed into the radiator (3) without any bolt-fixed element, such as bolts and rivets. The said structure consists of the foregoing components has the advantages as following:

[0015] 1. A simple structure for the directions of blades of the fan (1) has no hindered airflow and other obstacles. Therefore, inlet area of the air can be increased at its maximum and the noises can be decreased at its minimum.

[0016] 2. For connecting the fan (1) and frame (2) only by inlaying the retaining loops (22) into the grooves (31) of the radiator (3) and having the round periphery of frame (2) to firmly attached on the inner loop of the radiator (3). Of this connection shall be securely and firmly and without any bolt-fixed element.

[0017] 3. A partially hanging section between every spring lamination (25) and fold (241) can absorb the external and internal vibration energies of the fan (1) and can reduce the noises.

[0018] 4. A more convenient approach of assemble and dismantle for using of a good flexibility of the frame (2) to direct inlay the frame (2) into the radiator (3). And by pressure pushing these three retaining loops (22) for dismantling the assembled fan (1) and frame (2), which can easy take out the components in this device.

[0019] A summary for the mentioned structure which can use of a self-flexibility of the frame and an appropriate design of clasps and grooves in the radiator for assembling or dismantling or reassembling the fan assembled without any supplemental element such as bolts, rivets and so on. Then adapting with spring laminations and folds to absorb and eliminate the vibration energies of the fan's set for reducing the noises. The present invention has really the practical applicability and the creativeness, and has never been published to the public, that conforms the regulations specified in the Patent Law.
