Description

Firewall device capable of improving heat dissipation effect

Technical Field

The utility model relates to a prevent hot wall product field, more specifically say, it relates to a can improve hot wall device that prevents of radiating effect.

Background

The firewall mainly uses hardware and software to act on the internal and external network environments to generate a protective barrier, thereby realizing the blocking of the unsafe network factors of the computer.

The firewall product needs to dissipate heat during operation, the side walls of the existing firewall cases are provided with air exhaust holes, and fans are arranged in the cases to cooperate with the air exhaust holes to dissipate heat, for example, as shown in patent with publication number CN 205318294U.

However, only by using the fan in combination with the air outlet, the heat dissipation effect is limited, and how to further improve the heat dissipation effect is a direction of research in the industry.

SUMMERY OF THE UTILITY MODEL

Not enough to prior art exists, the utility model aims to provide a can improve the hot wall device that prevents of radiating effect, it has the advantage that improves the radiating effect.

In order to achieve the above purpose, the utility model provides a following technical scheme:

a firewall device capable of improving the heat dissipation effect comprises a shell, wherein a main board and a power supply module are respectively arranged in the shell, a plurality of air exhaust holes are formed in the side wall of the shell, and an exhaust fan opposite to the air exhaust holes is arranged on the inner side wall of the shell; the casing lateral wall is provided with the wind-guiding passageway, the wind-guiding passageway inside wall be provided with the reposition of redundant personnel portion that the exhaust fan is relative, casing lateral wall symmetry seted up with the fresh air inlet of wind-guiding passageway intercommunication.

Further, the air inlet hole is opposite to the main board.

Furthermore, a plurality of flow slowing parts are arranged on the inner side wall of the air guide channel.

Furthermore, the end face of the slow flow part is a spherical surface.

To sum up, the utility model discloses following beneficial effect has:

1. the air guide channel and the air inlet hole are adopted, so that the air flowing speed around the main board can be increased, and the heat dissipation effect can be improved;

2. the flow slowing part is adopted, the flowing time of hot air in the air guide channel can be prolonged, the hot air can fully carry out heat exchange, the air temperature is reduced, and therefore the heat dissipation effect can be improved.

Drawings

Fig. 1 is a schematic structural diagram of a firewall device capable of improving a heat dissipation effect according to an embodiment.

In the figure: 1. a housing; 11. an air exhaust hole; 12. an air inlet hole; 2. a main board; 3. a power supply module; 4. an exhaust fan; 5. an air guide channel; 51. a flow dividing section; 52. a flow buffering part.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications to the present embodiment without inventive contribution as required after reading the present specification, but all of them are protected by patent laws within the scope of the claims of the present invention.

Example (b):

a firewall device capable of improving heat dissipation effect, refer to fig. 1, which includes a housing 1, a main board 2 and a power module 3 are respectively arranged in the housing 1; a plurality of exhaust holes 11 are formed in the side wall of the shell 1, and an exhaust fan 4 opposite to the exhaust holes 11 is arranged on the inner side wall of the shell; the outer side wall of the shell 1 is provided with a wind guide channel 5, and the inner side wall of the wind guide channel 5 is provided with a shunt part 51 opposite to the exhaust fan 4; the side wall of the shell 1 is symmetrically provided with air inlet holes 12 communicated with the air guide channel 5, and the air inlet holes 12 are opposite to the main board 2 in the embodiment.

Referring to fig. 1, a plurality of flow slowing portions 52 are arranged on the inner side wall of the air guide channel 5, and the end surfaces of the flow slowing portions 52 are spherical surfaces in the embodiment; the provision of the flow slowing portion 52 can prolong the flow time of the hot air in the air guide passage 5, thereby enabling the hot air to sufficiently exchange heat, reducing the air temperature, and improving the heat radiation effect.

The working principle is as follows:

the hot-air in the casing 1 is discharged into the air guide channel 5 by the exhaust fan 4, the hot-air in the air guide channel 5 is divided into two directions by the shunting part 51 to flow respectively, the hot-air can carry out heat exchange when passing through the air guide channel 5, the air temperature can be reduced, the air after being cooled is blown to the mainboard 2 through the air inlet hole 12, the heat is dissipated to the mainboard 2, and the air after being heated enters the air guide channel 5 through the exhaust hole 11 to form circulation.
