The specific meaning of the above terms in the present utility model will be understood in specific cases by those of ordinary skill in the art.

The utility model is described in detail below by reference to the attached drawings and in connection with the embodiments:

in the prior art, for portable emergency communication equipment, when in operation, the internal components 3 generate certain heat, and the internal temperature of the equipment is easy to rise rapidly in an external environment with high temperature or high temperature. If the heat is not timely emitted, the equipment continuously heats up, the components 3 can fail due to overheating, and the equipment reliability is reduced. Therefore, it is important to efficiently perform heat dissipation processing on the circuit board in the device.

The traditional component 3 layout mode is that the PCB 2 is arranged on the bottom plate of the box body, the component 3 on the PCB 2 faces to the top cover 1 of the box body, and then the component 3 on the PCB 2 is radiated by arranging radiating equipment in the box body.

The utility model provides a box body with a hanging layout of components 3 with a heat dissipation function, and the problems can be solved by adopting a technical means of carrying out the hanging layout of the components 3.

As shown in fig. 1, 2 and 3, the box body with the hanging layout of the components 3 with the heat dissipation function provided by the utility model comprises: the top cover 1 positioned above the box body, the bottom plate positioned below the box body and the PCB 2 positioned between the top cover 1 and the bottom plate are characterized in that heat conducting glue is coated on the PCB 2, the upper surface of the PCB 2 is connected with the top cover 1 through the heat conducting glue, a component 3 oriented to the bottom plate in the vertical direction is arranged below the PCB 2, and air flows between the component 3 and the bottom plate.

Specifically, the component 3 faces the bottom plate, but the component 3 is not connected with the heat dissipation bottom plate, air flows between the component 3 and the heat dissipation bottom plate, and heat dissipation efficiency is improved by utilizing air convection.

Preferably, the PCB 2 in the box body with the overhanging layout of the components 3 with the heat dissipation function selects the MCPCB metal-based core circuit board, and the MCPCB metal-based core circuit board is characterized in that metal is used as a circuit board substrate, so that the heat dissipation performance of the PCB 2 can be greatly improved.

Preferably, the upper surface of the PCB board 2 is partially coated with a heat-conducting glue, so that the upper surface of the PCB board is connected with the lower surface of the top cover 1 through the heat-conducting glue, and the heat-conducting glue is used for conducting heat between the top cover 1 and the PCB board 2.

Specifically, the local coating is adopted because the local coating can form a good heat conduction channel between the PCB 2 and the top cover 1, and the whole coating can reduce the heat dissipation efficiency of the PCB 2. When the local coating position is selected, the hot area can be selected for coating, so that the hot area coincides with the contact point, the heat conduction efficiency can be improved, and the heat can be more quickly transferred from the PCB 2 to the top cover 1 and emitted.

Preferably, the heat conducting glue adopts anisotropic heat conducting glue. The anisotropic heat-conducting adhesive has insulating property and can be used for fixing the PCB 2 below the top cover 1. And the anisotropic heat conduction adhesive has special heat conduction performance, can conduct heat energy in one mode, but conduct heat in the other mode rarely, and can play a role in efficiently leading out heat generated in the box body and simultaneously blocking external environment heat from entering.

Preferably, the components 3 on the PCB 2 are staggered in the horizontal direction.

Specifically, in the horizontal direction, the high-power components 3 are arranged as close to the edge of the PCB 2 as possible and along the edge of the PCB 2 so as to shorten the heat transfer path; in the vertical direction, the high-power components 3 are arranged as close to the PCB board 2 as possible in order to reduce the influence of these components 3 on the temperature of the other components 3 when they are in operation.

Therefore, according to the box body with the overhang layout of the components 3 with the heat dissipation function, not only is the overhang layout adopted for the components 3 in the box body, but also the staggered layout mode is adopted for the components 3 in the box body in the horizontal direction and the vertical direction, so that the heat dissipation efficiency in the box body is increased, and more dense component 3 layout can be realized.

Preferably, the top cover 1 is further provided with a plurality of heat dissipation holes 11 and heat dissipation grids 12, and the heat dissipation holes 11 penetrate through the upper end face and the lower end face of the top cover 1.

Preferably, the bottom plate is further provided with a heat sink.

In summary, the utility model mainly adopts the technical means that the components 3 are arranged in a hanging mode and staggered mode, and utilizes air convection to improve the heat dissipation efficiency, and without adding excessive heat dissipation equipment, the dense arrangement of the components 3 can be realized under the condition of keeping a better heat dissipation function, so that the box body becomes miniaturized, and the carrying of operators is convenient.

It is to be understood that the above embodiments are merely illustrative of the application of the principles of the present utility model, but not in limitation thereof. Various modifications and improvements may be made by those skilled in the art without departing from the spirit and substance of the utility model, and are also considered to be within the scope of the utility model.
