Abstract

The utility model discloses a fan mounting base in a portable computer, which comprises a base body and a heat-radiation grid arranged on the base body. The width of the heat-radiation grid is smaller than the width of a fan, wherein a part of grid abutted with the fan is shrunk downwards, and the other part of the grid abutted with the fan is removed; fan supporting plates are symmetrically arranged at both sides of the grid in a transverse direction, and an end plate connected with the end of two supporting plates into integration is arranged at one side of the base body of which the grid is removed. Channels for supporting fan frames are arranged in the positions of the two supporting plate corresponding to the shrunk grid, and the inner side surfaces of the two supporting plates and two side parts of the grid form an air inlet channel and an air outlet channel which are communicated with an air channel composed of the end plate in order to form a circulation air channel for heat radiation. The circulation air channel for heat radiation can suck air for heat radiation from an air inlet composed of the two supporting plates at the ends of the fan and the grid, and heat on the base is carried away by the circulation air channel for heat radiation and is discharged from the other air outlet. Thus, a portable computer without heat radiation spaces can normally radiate heat.

Description

Radiation fan fitting seat in the portable computer

Technical field

The utility model relates to the computer of portable integrated structure, is specifically related to be used to install the radiation fan fitting seat of portable computer.

Background technique

In the prior art, the fan fitting seat that is used for computer main, by pedestal be arranged on the pedestal and constitute with the wide heat dissipating grid of fan, fan directly is pressed against on the heat dissipating grid, the another side of pedestal contacts with CPU, because the main frame of active computer is because the space is bigger, fan can be from its back exhausting, and discharge from the front, thereby the heat on the heat dissipating grid is taken away, heat distributes in cabinet to be extracted out outside the main frame by power supply fan and dispels the heat, and for the portable computer of integrated formation, because its thinner thickness, the fan back side does not have unnecessary space, complete machine adopts all-sealed structure, and the pedestal of existing structure can't be realized heat sinking function preferably, thereby influence the proper functioning of portable computer.

The model utility content

The technical problems to be solved in the utility model is, the fitting seat of the radiation fan in a kind of portable computer is provided, and adopts this fitting seat that radiation fan is installed, even fan not spacing of back also can make portable computer realize normal heat sinking function.

The technological scheme that solves the problems of the technologies described above that the utility model provides is as follows: construct a kind of fan fitting seat that is used for portable computer, comprise pedestal, be arranged on the heat dissipating grid on the described pedestal, the width of described heat dissipating grid is less than the width of fan, grid wherein a part of and that fan is adjacent shrinks downwards, another partly is removed with the adjacent grid of fan, both lateral sides at described grid is arranged with the fan support plate, be provided with the end plate that connects as one with described two support plate ends on the side pedestal of grid removing, the position that two support plates are corresponding with described contraction grid is provided with the deep gouge that is used for the supports fan frame, the inner side surface of two support plates and the both sides of described grid constitute into, the exhaust passage also is communicated with the air channel that described contraction grid is constituted with described end plate, constitutes the heat transmission circulation air path.

The fan fitting seat that adopts the utility model to provide, has following advantage: when fan work, the air channel that is made of support plate and grid can be drawn into the wind that is used to dispel the heat from the intake grill that two support plates and the grid of fan one side end constitutes, by the heat transmission circulation air path heat on the pedestal is taken away, take out of from another exhaust outlet, the air channel that is communicated with inlets and putlets of ventilation normally is set on the housing of portable computer, distribute by housing by circulation back, the air channel on the metal shell, even thereby realized fan not spacing of back, also can make the function of the normal heat radiation of portable computer.

Fig. 3 is the structure perspective view of fitting seat shown in Figure 1.

Embodiment

As Fig. 1, shown in 2, the fan fitting seat comprises pedestal 1, be arranged on the heat dissipating grid 2 on the pedestal 1, the width of heat dissipating grid 2 is less than the width of fan 3, wherein a part of and fan 3 adjacent grids 21 shrink downwards, another partly is removed with the adjacent grid 22 of fan, both lateral sides at grid 2 is arranged with fan support plate 11,14, be provided with and two support plates 11 removing on the side pedestal 1 of grid 22, the end plate 4 that 14 ends connect as one, two support plates 11,14 positions corresponding with shrinking grid 21 are provided with the deep gouge 12 that is used for the supports fan frame, two support plates 11, the both sides of 14 inner side surface and grid 21 constitute into, exhaust passage A, B also is communicated with the air channel C that is constituted with end plate 4, constitute the heat transmission circulation air path, shown in Fig. 2 arrow.

Be communicated with heat dissipation wind channel on the casing for ease of the inlets and putlets of ventilation in air channel, the end of two support plates 11,14 is mutually concordant with the end of grid 2.

For further improving radiating effect, can be with the some on two support plate deep gouges, 12 bases again to being lowered into the inlets and putlets of ventilation 13 that constitutes fan 3 both sides, make that the air quantity that enters the air channel is bigger, radiating effect is better, also outward extending heat dissipating grid 15 can be set in a side of pedestal, as shown in Figure 2, can further improve radiating effect.

Shown in Figure 3 is that CPU is installed in schematic representation on the pedestal back side, and the heat that is produced during CPU work is taken away by pedestal and air channel.
