Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention generally relates to a cooling device for dissipating heat in a portable computer. More specifically, the present invention relates to a cooling device that uses a blowing device that sucks air and conveys the air to a portable computer, and the power of the blowing device is supplied from a PCM CIA slot of the portable computer.

[0002]

[Prior art]

 Generally, heat generated in a portable computer is released to the atmosphere by an electric fan mounted near the rear of the portable computer. Due to the compactness and precision of the components in a portable computer's main frame, heat often cannot be efficiently released from within it. In addition, heat dissipation cannot be effectively dissipated by using only one electric fan in a portable computer.

[0003]

[Problems to be solved by the invention]

 Therefore, one object of the present invention is to provide a cooling device that uses a PCMCIA slot interface to obtain energy from a portable computer to drive a blowing means. It is another object of the present invention to provide a cooling device which is attached to a PCMCIA slot of a portable computer from the outside and draws air into the portable computer to generate convection of air therein.

[0004]

[Means for Solving the Problems]

 The cooling device for dissipating the heat of the portable computer is mainly composed of blow means, and transport means for introducing the air sucked by the blow means and transporting the air to the portable computer, and the blow means is attached to the transport means. Operated by a portable computer.

[0005] Another embodiment of a cooling device for dissipating heat of a portable computer includes a blowing means and a conveying means for introducing air sucked by a fan and conveying the air to the portable computer. The means may be secured to the vehicle and operated by a portable computer, and at least one power supply system may be configured to be secured to the vehicle to provide energy to the blowing means.

It should be noted that this cooling device applies a connector to an electrical connection to a PCMCIA port of a portable computer. The blowing means is operated by electric power supplied from the portable computer. When the cooling device is inserted into the PCMCIA slot of the portable computer, the air sucked by the blow means is forcibly passed through the transport means and finally injected into the portable computer. With respect to the electric fan installed in the internal space of the portable computer, the injected air sucked by the blowing means of the cooling device induces heat convection in the portable computer. This allows heat to be easily dissipated from the portable computer.

[0007] Other objects, features and advantages of the present invention will become apparent from the following detailed description of preferred but non-limiting embodiments. The detailed description is made with reference to the accompanying drawings.

[Embodiment of the invention]

 Please refer to FIG. 1, FIG. 2 and FIG. 3 simultaneously. FIG. 1 is a perspective view showing a cooling device 100 according to the present invention, FIG. 2 is an exploded view showing elements of the cooling device according to FIG. 1, and FIG. 3 is a cross-sectional view of the cooling device viewed from the Y direction in FIG. The cooling device 100 includes a conveying means (a housing 110 and a plate 120), a blow means 130, a connecting member 140, a grill cover 150, a filter 160, and a connector 170. A plate 120 having exhaust ports 121 and 122 formed thereon is mounted on tracks 111 and 111 of a housing 110, and a pair of support members 112 and 112 are formed in a first surface 110F in the housing. Used to support the plate 120. The blow means 130 can be coupled to the connection member 140 by screwing. This screwing is performed from the hole 140H of the connecting member 140 through the hole 130H of the blow means 130. The connecting member 140 is attached to the step portion 113 of the housing 110, and the blow means 130 is housed in the housing 110. A symmetrical rib 141 having a vent is formed in the connecting member 140. A filter 160 is provided between the grill cover 150 and the connecting member 140 to clean the inflow of air. Therefore, the air sucked by the fan 131 of the blow means 130 is introduced into the housing 110. When the plate 120 is placed on both tracks 111 of the housing 110, a clearance G is formed between the end of the plate 120 and the housing 110 as shown in FIG. Fins 121F and 122F formed in the exhaust ports 121 and 122 project into the space between the housing 110 and the plate 120, and the rake of the fins 121F and 122F guides a part of the air passing through the exhaust ports 121 and 122. it can. Therefore, the sucked air is forcibly advanced into the space between the housing 110 and the plate 120, and passes through the exhaust ports 121 and 122 and the clearance G along the dotted line A.

Referring to FIGS. 4 and 5, a PCMCIA slot 210 is located on the side wall of portable computer 200, and each PCMCIA slot typically has two PCMCIA connection ports (not shown). The cooling device 100 is electrically connected to the port, and the blowing means 130 is operated. Therefore, air is sucked from the atmosphere by the blow means 130 and sent to the portable computer 200 through the PCMCIA slot 210. Further, the sucked air can contribute to heat convection in the portable computer 200. As a result, heat generated in the portable computer 200 is easily released by an electric fan (not shown) provided in the portable computer 200.

In FIG. 6 and FIG. 7, one PCMCIA card 10 and cooling device 100 are used to be simultaneously coupled to a PCMCIA connection port of a portable computer 200. Since the length of the PCMCIA card 10 can be accommodated above the cooling device 100, the PCMCIA card 10 can be placed above the plate 120 of the cooling device 100.

FIG. 8 shows another embodiment of a cooling device 100 ′ having a power supply device (a battery bracket 150 ′ and a battery 150 ′ B) according to the present invention. The storage battery 150 ′ B can supply energy alone to the blow means 130 while considering the consumption of the Ni—Cd battery of the portable computer 200. While the present invention has been described in terms of the presently considered most practical and preferred embodiment, the present invention is not limited to the embodiments described, but rather by the spirit and concept of the appended claims. It is needless to say that various variations and equivalent modifications are included.
