Combined structure of combination fan

Abstract

The invention discloses a combined structure of a combination fan. The combined structure is used for enabling at least two fans to be combined into a whole. The combined structure comprises at least one combination hole, at least one combination column and a sticking layer. The at least one combination hole is arranged in a frame body of a first motor in a penetrating mode. The at least one combination column is arranged in a frame body of a second motor in a protruding mode, the structure of the combination column is matched with that of the combination hole, and the combination column is contained in the combination hole in a penetrating mode. The sticking layer is arranged between the outer wall of the combination column and the inner wall of the combination hole in a sticking mode. Thus, the two frame bodies of the fan are firmly combined together.

Description

technical field [0001] The present invention relates to a combination structure, in particular to a combination structure of a combined fan. Background technique [0002] The fan is mainly used to dissipate heat from a heat-generating object, for example, to dissipate heat from a server. [0003] The air volume of the fan depends on the size of the fan and the horsepower of the fan motor. However, it is difficult and costly to manufacture a large-scale fan directly; therefore, it is usually made into a plurality of smaller unit motors, and then the unit motors are combined to form an integrated fan of a predetermined size. . For example, if you want to make a fan with a size of 40*40*56 (unit mm) used in a server, you usually make two unit fans with a size of 40*40*28 first, and then combine the two unit motors to form a 40*40*56 an all-in-one fan. [0004] To combine two or more unit fans into an integrated fan, a combined structure must be used. A known combined struc...

Problems solved by technology

[0005] However, this known combination structure has the following disadvantages in use: (1), it must be provided with a connector and a C-shaped button in addition, and must be provided with a slit on the outer wall of the connector, especially on the inner wall of the fan frame. The structure is complex and the assembly is inconvenient; (2) After the connectors and the C-shaped buckle are assembled with the fan, they are located inside the fan frame. These connectors and the C-shaped buckle will hinder the transmission of part of the air volume of the fan and reduce the efficiency of the fan; ( 3) The connecting piece and the C-shaped buckle are only to achieve the series connection of the front and rear fans in the axial direction. The connecting piece, the C-shaped buckle and the fan frame are still separated from each other and are not firm. The combination of the ground and the ground will cause vibration to occur. When the fan is running, it will cause the vibration of the whole frame

[0006] Due to the above reasons, the applicability of the known combined structure of the integrated fan is not good.
