Description
Technical Field
The utility model relates to a small-size fragment of brick power module structure belongs to power module technical field.
Background
The power module has the outstanding advantages of small size, high power and the like, and the size of the power module is like a brick, so the power module is called a brick power supply. The small-sized brick power supply is one of the large-power small-sized brick power supply modules with wide application, at present, because the product power design demand of the small-sized brick power supply is increasingly large, the density of components is increasingly high, and the demand of miniaturization of the volume is increasingly inclined, the heat generated in corresponding work is also increased, in order to solve the heat dissipation problem, a heat dissipation device for dissipating heat or transmitting the heat to a client side must pass through a heat sink, therefore, the surface of the heat dissipation device is required to ensure enough flatness, the heat dissipation device can be effectively attached to the client side heat dissipation device, the safe distance between the heat dissipation device and the components is ensured, otherwise, the heat dissipation capacity of the power supply module is greatly reduced, the safe distance between the components and the heat dissipation device cannot be ensured, and the working efficiency and the service.
Disclosure of Invention
The utility model discloses the technical problem that will solve lies in: the utility model provides a small-size fragment of brick power module structure, it has solved the problem of the uniformity of present power module fin package height and components and parts safe distance.
The utility model discloses the technical problem that will solve takes following technical scheme to realize:
the utility model provides a small-size fragment of brick power module structure, it includes radiator and PCBA circuit board, be provided with a plurality of components and parts on the PCBA circuit board, equal fixedly connected with boss of three corner department and pilot pin of radiator, it is three the upper surface of boss is the same with the setting to the high homogeneous phase of bottom surface of radiator, seted up three mounting hole on the PCBA circuit board, the PCBA circuit board sets up on three boss, and is three the pilot pin runs through three mounting hole respectively.
By adopting the technical scheme, during assembly, high-thermal-conductivity filling glue is firstly applied to the heating component points on the top surface of the PCBA circuit board, then three positioning pins of the radiator are pressed to the bottom corresponding to three mounting holes on the top surface of the PCBA circuit board, and fixing glue is applied between the mounting holes on the bottom surface of the PCBA circuit board and the positioning pins, so that the assembly can be completed, and the operation is convenient and rapid.
As a preferable example, the bottom surface of the heat sink is provided with a plurality of gradient shapes according to the height of the component.
By adopting the technical scheme, the height consistency of the heat radiator during installation of the PCBA circuit board is further improved, and the safe distance between the PCBA circuit board components and the heat radiator is effectively ensured.
The utility model has the advantages that: the utility model discloses an with the equipment mode of radiator, pilot pin and boss, the uniformity of height when can improving radiator installation PCBA circuit board can guarantee the safe distance of PCBA circuit board components and parts and radiator again, and the equipment is simple moreover, and the operation of being convenient for can the wide application in all kinds of small-size fragment of brick power.

Fig. 1 is a schematic structural view of the present invention;
FIG. 2 is a schematic view of the heat sink of the present invention;
FIG. 3 is an assembly effect diagram of the present invention;
in the figure: the heat radiator comprises a heat radiator 1, a boss 2, a positioning pin 3, a PCBA circuit board 4, a mounting hole 41 and a component 5.
Detailed Description
In order to make the technical means, the creation features, the achievement purposes and the functions of the present invention easy to understand and understand, the present invention is further explained by combining the following specific drawings.
As shown in fig. 1-3, a small-size fragment of brick power supply structure, including radiator 1 and PCBA circuit board 4, be provided with a plurality of components and parts 5 on the PCBA circuit board 4, equal fixedly connected with boss 2 of three corner department and pilot pin 3 of radiator 1, the equal setting of bottom surface height of three boss 2 to the radiator has been seted up three mounting hole 41 on the PCBA circuit board 4, and PCBA circuit board 4 sets up on three boss 2, and three pilot pin 3 runs through three mounting hole 41 respectively.
During the equipment, at first go up high heat conduction filling glue at the top surface heating element 5 point of PCBA circuit board 4, correspond mounting hole 41 on PCBA circuit board 4 with pilot pin 3 on the radiator 1 again, press to the end, point fixed glue between mounting hole 41 and the pilot pin 3 of PCBA circuit board 4 afterwards, can accomplish the equipment, convenient operation is swift.
The utility model discloses a boss 2 and pilot pin 3 on the radiator 1 are in the same place PCBA circuit board 4 and radiator 1 are fixed, and the equipment is convenient to some high heat conduction filled glue between components and parts 5 of PCBA circuit board 4 and radiator 1, strengthen power module's radiating effect, improve power module's life.
The basic principles and the main features of the invention and the advantages of the invention have been shown and described above. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that various changes and modifications may be made without departing from the spirit and scope of the invention, and such changes and modifications fall within the scope of the invention as claimed.
