Description

Windshield and heat dissipation system using the same

This creation is about a heat dissipation system and its related components, especially regarding a windshield applied to a fan module.

Generally speaking, an electronic product (for example, a servo system) is provided with a heat dissipation system, and a heat dissipation fan of the heat dissipation system can blow air into the interior of the electronic product, and the heat generated by the operation of the electronic product is dissipated to the surrounding environment by the heat convection effect.

In a heat dissipation system including a plurality of cooling fans, when one of the cooling fans fails, the wind pressure inside the heat dissipation system is lowered. At this time, in order to maintain considerable heat dissipation efficiency, the remaining cooling fans need to operate at a higher rotational speed. However, this causes turbulence in the flow of air, which causes loud noise and is quite energy intensive. In addition, long-term high-speed operation also makes it easy to reduce the service life of the cooling fan.

Therefore, an element that can block external airflow from entering the heat dissipation system to avoid a change in the flow field inside the fan module is highly demanded.

In view of this, the main purpose of this creation is to propose a windshield that is used to shield the outside when the cooling fan in the cooling system fails. Air enters the cooling system to stabilize the airflow field inside the cooling system.

In one embodiment, the windshield is applied to a fan module including a frame body and a heat dissipation fan. The fan module has an opening formed on the front end surface of the frame body, and the heat dissipation fan is disposed in the frame opposite to the opening. The windshield includes a body and a magnetic element. The body has a plurality of positioning grooves recessed from the surface of the body, wherein the positioning groove is adjacent to the opening end with respect to the front end surface. The magnetic component is fixed in the positioning groove and is magnetically coupled to the front end surface of the frame in a detachable manner. When the magnetic component is magnetically coupled to the front end surface of the frame body, the body covers the opening to block the external airflow from passing through the opening.

In the above embodiment, the body has a first side edge and a second side edge opposite the first side edge, the positioning groove is located adjacent to the first side edge and the second side edge, and/or the positioning groove is along the first side edge Arranged in the direction of the second side edge.

In the above embodiment, the thickness of each of the magnetic elements is at or less than the depth of the corresponding positioning groove, so that the body is attached to the frame of the fan module.

In the above embodiment, the windshield further includes a handle, wherein the body includes a first surface and a second surface opposite the first surface, the handle protrudes outwardly from the first surface, and the positioning grooves are disposed on the second surface. Alternatively, the windshield further includes a through hole through which the body is disposed. The user can use the handle or through hole to take or place the windshield.

In the above embodiment, the present system of the windshield is made of a material containing plastic to achieve a slim design.

In addition, the present invention provides a heat dissipation system using the above windshield, and the heat dissipation system includes: a frame body, a heat dissipation fan, and a windshield. The frame has a front end surface and an opening formed on the front end surface of the frame. The cooling fan is selectively disposed in the frame relative to the opening, wherein when the cooling fan is damaged, the windshield covers the opening of the damaged cooling fan.

In the above embodiment, the fan module includes a plurality of cooling fans, and the frame includes a plurality of openings, and the cooling fan is selectively disposed in the frame with respect to one of the openings, wherein one of the cooling fans moves from the frame In addition, the windshield covers the opening of the cooling fan that is originally opposed to the one.

Since the windshield can be quickly installed on the fan module, when the cooling fan fails, the maintenance personnel can have sufficient service time to replace the good cooling fan and maintain the stability of the electronic device to which the heat dissipation system is applied.

Referring to FIG. 2, the windshield 200 includes a body 210, a plurality of magnetic components 230, and a handle 250. The body 210 has a first side edge 210a, a second side edge 210b, a third side edge 210c and a fourth side edge 210d, wherein the first side edge 210a and the second side edge 210b are opposite to each other, and the third side The edge 210c and the fourth side edge 210d are respectively coupled between the first side edge 210a and the second side edge 210b. A plurality of positioning slots 215 are recessed from the second surface 213 of the body 210. In this embodiment, the positioning groove 215 is located adjacent to the first side edge 210a and the second side edge 210b, and is adjacent to the position of the opening 111 with respect to the front end surface 113 of the frame 110. More specifically, the positioning groove 215 is arranged along the direction of the first side edge 210 and the second side edge 210b, and is arranged with respect to the upper portion 113a and the lower portion 113b of the front end surface 113 of the frame 110. In the manufacturing process, the body 210 is a thin plate made of a material containing plastic, and the positioning groove 215 is formed by Milling machining.

The arrangement of the positioning grooves 215 should not be limited to the above embodiment. In another embodiment, the number of the positioning slots 215 is two, each extending in the direction of the first side edge 210a and the second side edge 210b. In another embodiment, the positioning groove 215 is arranged along the direction of the third side edge 210c and the fourth side edge 210d of the body 210. In another embodiment, the positioning groove 215 is aligned along at least one of the first, second, third, and fourth side edges 210a-d of the body 210. In addition, the number of positioning slots 215 should not be Without limitation, those skilled in the art can arbitrarily increase or decrease the number of positioning slots 215 to meet the demand.

The magnetic element 230 is disposed in each of the positioning grooves 215 and is fixed by an appropriate means, for example, inlay. The handle 250 includes a grip portion 251 and two end portions 253.
