ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The invention relates to a heat-dissipating device, more particularly to a heat-dissipating device that further serves to reinforce an equipment housing.
2. Description of the Related Art
FIG. 1
illustrates a conventional heat-dissipating device for dissipating heat generated by a CPU
14
disposed on a main board
15
inside a computer housing (not shown). The conventional heat-dissipating device includes a heat transfer plate
10
, a heat exchanger pipe
11
connected to the heat transfer plate
10
, a heat sink
12
coupled to the heat exchanger pipe
11
, and a fan
13
connected to the heat sink
12
. The fan
13
is generally mounted on the computer housing
12
(not shown).
As shown in
FIG. 2
, when the CPU
14
and electronic components underlying the heat exchanger pipe
11
have to be replaced or repaired, the fan
13
is detached from the housing, and the heat transfer plate
10
is detached from the CPU
14
, thereby leading to inconvenience during replacing and repairing.
SUMMARY OF THE INVENTION
Therefore, the object of the present invention is to provide a heat-dissipating device that can be easily assembled and that further serves to reinforce an equipment housing.
According to the present invention, a heat-dissipating device is adapted for dissipating heat inside an equipment housing. The equipment housing includes a housing part having upright first and second side walls and a bottom wall interconnecting bottom edges of the first and second side walls. The first and second side walls extend transverse to each other such that the first and second side walls and the bottom wall cooperate to form a corner portion of the housing part. The first side wall is formed with a vent hole adjacent to the second sidewall. The heat-dissipating device includes a remote heat-dissipating unit and a fan unit.
The remote heat-dissipating unit is adapted to be disposed in the equipment housing, and has a heat transfer plate, a heat exchanger pipe connected to the heat transfer plate, and a heat sink coupled to the heat exchanger pipe.
The fan unit is adapted to be disposed in the corner portion of the housing part. The fan unit includes a fan housing, a fastening seat member and a supporting member. The fan housing has a fan disposed therein. The fastening seat member is adapted to be fastened removably on the first side wall and the bottom wall of the housing part, and retains the fan housing in the housing part adjacent to the vent hole in the first side wall. The supporting member has an anchoring frame part connected to the fan housing, a reinforcing frame part extending from the anchoring frame part and adapted to be disposed adjacent to the second side wall, and a fastening frame part extending transversely from the reinforcing frame part and spaced apart from the fan housing to form a sink mounting space therebetween. The heat sink is disposed in the sink mounting space, and is fastened removably to the fastening frame part.
In view of its novel arrangement, the fan unit further serves to reinforce the corner portion of the housing part of the equipment housing.
