The heat conducting layer can be a heat conducting silica gel layer or a heat conducting silicone grease layer; the heat conduction layer can also be added with metal powder to increase the heat conduction.

Specifically, the box 100 is used for accommodating and installing the base station function unit of the base station device, so as to provide a stable working environment for the base station function unit and prolong the service life of the base station function unit.

The specific case 100 may be made of different materials, such as polymer material, or metal material, such as stainless steel material; in addition, composite materials can also be selected.

For example, the box 100 may have a rectangular parallelepiped shape or a rectangular prism, in this case, taking the rectangular parallelepiped as an example, the rectangular parallelepiped generally includes 6 faces, that is, 6 installation faces, and the base station function unit is also provided with a plurality of base station function units, for example, a currently general base station function unit may include: baseband processing unit, power amplifier, filter and power. In this case, the baseband processing unit, the power amplifier and the power supply are the heating unit 200; each of the heat generating units 200 is mounted on a side surface or a bottom surface of the case 100.

In this case, for example, the area sequence of the 6 mounting surfaces is, from large to small, the top surface, the bottom surface, the first side surface, the second side surface, the third side surface and the fourth side surface, in this case, for example, the baseband processing unit, the power amplifier and the power supply may be respectively mounted on the top surface, the bottom surface and the first side surface.

In this case, compared with the prior art in which all the base station functional units are disposed on the same surface, the present solution can comprehensively utilize more areas, and increase the heat dissipation area. According to the scheme, different heating units 200 are arranged on different installation surfaces, so that the heat dissipation area of the box body 100 is comprehensively utilized, the quick heat dissipation of the heating units 200 in the base station is facilitated, and the functional units of the base station are maintained to work at normal temperature.

In a specific embodiment, the larger the heating value, the larger the area of the mounting surface on which the heating unit 200 is located.

Specifically, in order to sufficiently improve the utilization rate of the heat dissipation area as much as possible, in the present scheme, the heating unit 200 with a large heat generation amount is selected to be arranged on the installation surface with a large area, specifically, for example, 3 heating units 200 are respectively the unit 1, the unit 2, and the unit 3; wherein, the heat productivity of the unit 1, the unit 2 and the unit 3 is increased in sequence; in this case, if the case 100 is a cube, there are 6 mounting surfaces, and the top surface, the bottom surface, the first side surface, the second side surface, the third side surface, and the fourth side surface are arranged in order of the size of the area from the large to the small, and in this case, the unit 1 is disposed on the top surface, the unit 2 is disposed on the bottom surface, and the unit 3 is disposed on the first side surface.

In a specific embodiment, as shown in fig. 3, the method further includes: a heat-dissipating toothed plate 130; the heat dissipation toothed plate 130 is disposed on the outer wall of the box body 100 at a position corresponding to the mounting surface.

Specifically, in order to further increase the heat dissipation area, a heat dissipation toothed plate 130 may be further disposed on the outer wall of the box body 100.

Further, the number of the heat dissipation tooth plates 130 is one or more.

Specifically, only one heat dissipation toothed plate 130 may be provided, or a plurality of heat dissipation toothed plates 130 may be provided, so as to passively improve the heat dissipation efficiency by physically increasing the heat dissipation area.

Specifically, the heat dissipation toothed plate 130 may be an aluminum heat dissipation toothed plate 130, or a copper heat dissipation toothed plate 130, or a heat dissipation toothed plate 130 made of other materials.

In a specific embodiment, the method further comprises the following steps: a reservoir 140, wherein the reservoir 140 is disposed outside the case 100.

Specifically, in addition to the above manner, considering that many base stations are disposed in an outdoor environment, and the outdoor environment may be rainy, that is, may contact water, and considering that water is also beneficial for heat dissipation, the water storage tank 140 may be disposed outside the box body 100, so as to take away heat by evaporation of water in the water storage tank 140.

Specifically, as shown in fig. 4, the reservoir 140 may be detachably connected to the outer side of the box 100, or may be integrally provided with the box 100. The particular reservoir 140 may be, for example, a rectangular parallelepiped, which is open upward when installed.

Specifically, the reservoir 140 may be magnetically connected to the outer side of the box 100 or be connected to the outer side in a clamping manner.

Specifically, considering that water has certain corrosiveness, in order to ensure heat dissipation and prevent the base station from being corroded, the water storage tank 140 made of a high polymer material can be selected, and durability is improved.

In a specific embodiment, the integrated high-power base station internal unit can be divided into: the system comprises four units, namely a baseband processing unit (BBU), a power amplifier, a filter and a power supply. The baseband processing unit, the power amplifier and the power supply are the heating unit; each hair extension unit is arranged on the side surface or the bottom surface of the box body.

Wherein, BBU, power amplifier and power supply three are heating unit 200, and the power amplifier is the most serious to generate heat, according to different power amplifier output levels, and the heat consumption is between tens of watts to hundreds of watts.

BBU and power supply heat the second time. Typically, BBU heat dissipation is within 20 watts. For example, the BBU heat consumption of the 4G single carrier of the department of I is 8W, the BBU heat consumption of the 4G double carrier is 15W, and the BBU heat consumption of the 5G single carrier is 18W.

The heat consumption of the power supply is different according to the power supply of the system power supply, and the power supply efficiency is about 92 percent generally. Therefore, the heat consumption is about 20-30W when the power is calculated by 300W.

For example, there is a cartridge 100 with internal dimensions of up to 350 x 540 x 120mm and external dimensions of 420 x 600 x 225 mm. The chassis may be divided into a total of six sides as shown in fig. 1.

Wherein the top and bottom surfaces have the largest area. In the traditional design, the bottom surface is mainly used for heat dissipation and unit fixation, namely all BBUs, power amplifiers, power filters and the like are fixed on the bottom surface. In this solution BBU is fixed to the side. The top surface or the bottom surface is fixed with a power amplifier. The actual heat dissipation area of one side is 220 × 600 ═ 132000 square centimeters, the thickness is basically estimated and calculated according to the working conditions of the conventional outdoor base station above 5mm, and 132000 square centimeters can meet the 80w heat dissipation requirement.

In addition, the baseband processing unit is arranged to be installed on the side surface of the box body in a long strip shape.

The size of the baseband plate where the baseband processing unit is located is enough to be placed on the side face of the case, and the power supply is fixed to the other side face to dissipate heat. The internal dimension of the other side face is 350 x 120mm, the placement and the arrangement of a power supply can be met, and the heat dissipation dimension is 420 x 225mm, so that the heat dissipation requirement of the power supply can be met.

The power amplifier unit is fixed on the top surface or the bottom surface for heat dissipation. The internal dimension of the A/B surface is 350 mm 540mm, and the heat dissipation dimension is 420 mm 600 mm. And the two sides also have heat dissipation teeth, so that each side can meet the 180W heat dissipation requirement through conventional calculation and estimation. In addition, the other side surfaces can be used as leading-out surfaces of power lines, antennas and the like, and through holes are reserved. The other non-heat dissipation units such as filters can be arranged at will.

An embodiment of the present invention provides a base station apparatus, including: an openable and closable case 100, and a base station function unit provided in the case 100; the inner wall of the box body 100 is provided with a plurality of mounting surfaces; the base station functional unit comprises a plurality of heating units 200, and different heating units 200 are arranged on different installation surfaces.
