Abstract

The utility model discloses a passageway exchange. A main board and a power supply board are used as an independent main board module and a power supply module. Casings of the main board module and the power supply board are made of high heat-conduction aluminum alloy materials. A cooling plate arranged on the power supply module tightly contacts to the casing of the power supply module, thereby the heat can be conducted rapidly. Cooling devices are disposed on a plurality of chips with high heat production of the main board module, and each cooling device is tightly contacted to the main board module. The main board module, the power supply module and a machine box are tightly contacted, increasing the heat conducting capacity of members installed inside the device to the machine box. The machine box employs aluminum alloy castings and is provided with a plurality of cooling bars, thereby improving the heat conducting capacity of the machine box to the external. The surfaces of all circuit modules and member installed inside the machine box are sprayed with three-proof paint, completely meeting the three-proof need. The utility model has the advantages of sound cooling effect, dust prevention, mildew resistance, salt fog prevention, simple structure and low costs.

Description

A kind of corridor switch

Technical field:

The utility model relates to a kind of switch, particularly relates to a kind of corridor switch of high-speed wideband network.

Background technology:

Along with the development of modern science and technology level and the raising of people's living standard, the change of life style, the high-speed wideband network begins to enter into huge numbers of families.The corridor switch has become the essential equipment that the high-speed wideband network is built in the residential quarter.Because it is installed in the corridor metope or outdoor casing of residential building, require sealing, dustproof, mildew-resistant, anti-salt fog, operational environment is comparatively abominable, and the switch inner space is smaller, and the mainboard area is bigger, and power consumption mainly concentrates a few to concentrate on the circuit on a large scale, the operating temperature range of mainboard is-30 ℃ of ∽+50 ℃, and environment needs quiet, and switch mustn't use the fan forced heat radiation, can only adopt natural heat dissipation.

Summary of the invention:

Technical problem to be solved in the utility model provides a kind of good heat dissipation effect, can prevent dust, mildew-resistant, anti-salt fog and corridor switch simple in structure.

The technical solution adopted in the utility model is: mainboard and power supply are made independently mainboard module and power module, the shell of mainboard module and power module adopts the aluminum alloy materials of high heat conduction, heating panel on the power module closely contacts with the shell of power module, on the chip that several caloric values are big on the mainboard module, radiator is installed, each radiator closely contacts with mainboard module, cabinet adopts aluminium alloy castings, and being provided with many radiating ribs, mainboard module closely contacts with cabinet with power module; All circuit modules and components and parts surface are coated with three anti-lacquers in the cabinet.

Because mainboard and power supply are made independently mainboard module and power module, the shell of mainboard module and power module adopts the aluminum alloy materials of high heat conduction, heating panel on the power module closely contacts with the shell of power module, make heat conduct out fast, on the chip that several caloric values are big on the mainboard module, radiator is installed, each radiator closely contacts with mainboard module, mainboard module closely contacts with cabinet with power module, improved of the heat transfer (conduction of the components and parts of device interior to cabinet, convection current, radiation) ability, cabinet adopts aluminium alloy castings, and be provided with many radiating ribs, increased area of dissipation, improved the capacity of heat transmission of cabinet to the external world; All circuit modules and components and parts surface are coated with three anti-lacquers in the cabinet, can reach three anti-requirements fully, so the utility model good heat dissipation effect can be prevented dust, mildew-resistant, be prevented salt fog, and simple in structure, with low cost.

Description of drawings:

Fig. 1 is the utility model structural representation.

Embodiment:

Referring to Fig. 1, be provided with mainboard in the cabinet 1 of corridor switch, power panel, heating tank 9, add thermal control plate 10 and heating module 13, optical fiber fuses box 12 and fiber optical transceiver 11, mainboard and power panel are made independently mainboard module 1 and power module 5, the shell of mainboard module 1 and power module 5 adopts the aluminum alloy materials of high heat conduction, heating panel 2 on the power module 5 closely contacts with the shell of power module 5, make heat conduct out fast, radiator 4 is installed on the chip that several caloric values are big on the mainboard module 1,6,7,8, radiator 4,6,7,8 closely contact with mainboard module 1, mainboard module 1 closely contacts with cabinet 3 with power module 5, improved the heat-transfer capability of the components and parts of device interior to cabinet 3, cabinet 3 adopts aluminium alloy castings, and be provided with many radiating ribs, increased area of dissipation, improved the capacity of heat transmission of cabinet 3 to the external world; All circuit modules and components and parts surface are coated with three anti-lacquers in the cabinet 3, can reach three anti-requirements fully.
