Description

BACKGROUND OF THE INVENTION

The present utility model relates to the field of computer fans, in particular relating to a fan group with a magnetic-type clamping connection module.

Computer fans, also known as cooling fans, are generally used for heat dissipation. The cooling fans are provided for radiators and computer cases. The general cooling fans on the market range from 2.5 cm to 30 cm in diameter, and from 6 mm to 76 mm in thickness.

With the upgrading of computer hardware (graphics card, CPU), their working frequency also becomes higher; therefore, a single cooling fan cannot realize the expected heat dissipation effect, resulting in hardware damages.

As a result, generally, a plurality of single fans are connected in series through wires or the interfaces of the single fans are connected with the power supply respectively in order to realize the multi-fan operation and thus achieve the expected heat dissipation effect (for example, the single fans are installed as a cooling fan group or installed in a water-cooled radiator).

However, such structure results in more and messy electrical connection in a computer and thus easily results in unstable operation of fans. In other words, it is impossible to configure the cooling fans as per users' needs, meaning a significant limitation. Certainly, the cooling fans may be arranged with power interface modules; however, if the cooling fans are arranged with power interface modules, the assembly steps of the cooling fans will increase and the cost of a single fan will increase accordingly; take the Chinese patent numbered 202220594054.5 as an example, it is necessary to arrange the first electrical connecting parts and the second electrical connecting parts at different positions of the housing, meaning relatively cumbersome installation steps.

BRIEF SUMMARY OF THE INVENTION

The main purpose of the present utility model is to propose a fan group with a magnetic-type clamping connection module, aiming to improve the existing fan combination structure, lower the cost of a single fan and thus reduce the assembly processes through the connection module.

To achieve the purpose described above, the present utility model provides a fan group with a magnetic-type clamping connection module, comprising:

• • a housing, wherein the outer wall of the said housing is arranged with four splicing sides, and the connecting end between two splicing sides is arranged with a concave locating groove, the upper and lower ends of the inner side of a locating groove are symmetrically arranged with stepped grooves, and a locating groove is arranged with a first electrical connecting part and a plurality of first electrical connecting parts in the same housing are mutually connected in series;
  • a locating groove is arranged with a first magnetic member;
  • a connection module, wherein the said connection module is a base arranged vertically and symmetrically, and its shape fits the combined shape of two locating grooves or fits the shape of a single locating groove,
  • the said connection module is arranged with a second magnetic member that matches the first magnetic member, the said connection module is arranged with stepped parts that fit the stepped grooves, and the walls of the base are arranged with second electrical connecting parts that fit the first electrical connecting parts.

In practical use of the technical solutions of the present utility model, the connecting module is arranged with stepped parts to make the base take on a symmetrical clamping structure;

When the housing is a whole, the size of the base fits the locating grooves and the base is arranged with one first electrical connecting part and one first magnetic member to realize electrical connection of independent fans, and four connecting ends of the housing can be placed at any positions as per the user's actual installation.

When the housing is divided into two halves, the size of the base fits the locating grooves and the base is arranged with two first electrical connecting parts and two first magnetic members to realize the splicing of two housing halves, mutual adsorption of the first magnetic members and the second magnetic members can realize the fixation between two fans; the structure is simple and the base of the connection module is more inexpensive when being made.
