Description

Laptop External Cooler

technical field

The utility model relates to a cooling device for a notebook computer, in particular to an external heat sink for a notebook computer.

Background technique

A notebook computer, or notebook for short, is a small, portable personal computer with poor heat dissipation. A laptop device refers to a device that helps a laptop to dissipate heat, and generally includes a laptop desk or stand with a fan. In order to improve the heat dissipation effect of notebook computers, some external cooling devices of notebook computers do not adopt the form of notebook computer tables or racks, such as the patent No. ZL200520063670.4 disclosed in Chinese patent documents, the date of authorization announcement was November 29, 2006, practical The new name is "support seat for notebook computer". A USB module and a HUB module connected to the USB module are plugged in; therefore, the support base has a device for assisting the heat dissipation of the notebook computer and also has the structural design of the USB module and the HUB module. However, although the support base is easy to carry, its heat dissipation area is still limited to the air flow range involved in the fan and the heat dissipation at the bottom, and its heat dissipation effect is relatively poor.

Contents of the invention

In order to overcome the above disadvantages, the purpose of this utility model is to provide the field with an external heat sink for notebook computers with a return-shaped heat pipe and two-way air flow heat dissipation, so that it can solve the problems of slow heat dissipation and low heat dissipation effect of existing similar products. Poor technical issues. Its purpose is achieved through the following technical solutions.

An external heat sink for a notebook computer, the external heat sink includes a bottom plate, a space frame, a fan, an adjustable support frame, and a return-shaped heat dissipation pipe, the bottom plate is provided with a USB interface of the fan, and the fan is powered through the USB interface. The main points of the design are that the bottom plate is L-shaped, the bottom plate is provided with a return-shaped heat dissipation pipe and a fan, the nozzle of the return-shaped heat dissipation pipe is connected with the air outlet of the fan, and the outer diameter of the return-form heat dissipation pipe is provided with a through hole, and the through hole faces The interface between the laptop and the chassis. The external heat sink utilizes the through hole and the external fan to make the natural wind blown from the through hole on the circular heat dissipation pipe accelerate the air flow of the notebook computer, reduce the temperature of the notebook computer, and accelerate the cooling effect. One end of the L-shaped bottom plate protrudes as a baffle to prevent the notebook computer on the bottom plate from sliding down.

The bottom plate is connected to the space frame in the shape of "[", and the space frame is provided with a baffle plate and a return-shaped heat dissipation pipe. It is opposite to the through hole of the return-shaped heat dissipation pipe on the base plate. Laptops are placed in the clip slot between the bottom plate and the space frame bracket, and the laptop is connected to an external keyboard. The return-shaped heat dissipation pipes on the upper space frame and the return-shaped heat dissipation pipes on the lower bottom plate blow out natural wind from the through holes through the fan to speed up the heat dissipation of the notebook computer. Effect.

The bottom plate is provided with an adjustable support frame. The bottom plate can be used independently or in combination with the space frame, or in combination with the adjustable support frame alone, or in combination with the space frame and the adjustable support frame.

The utility model has the advantages of reasonable design, convenient loading and unloading and use, various combination modes, fast heat dissipation speed and good heat dissipation effect, and is suitable for heat dissipation of notebook computers.

Detailed ways

In conjunction with the accompanying drawings, the utility model will be further described. Embodiment 1 shown in Figure 1, base plate 1 is L-shaped, and the L portion protrusion of the bottom is connected with space frame 2, and space frame is provided with baffle plate 5, is provided with the gap of placing notebook computer thickness between base plate and space frame. The bottom plate and the space frame are respectively provided with return-shaped heat dissipation pipes 21, and the return-form heat dissipation pipes at the bottom communicate with the return-shaped heat dissipation pipes of the space frame. The bottom of the bottom plate is provided with a fan 3, and the fan is connected with the circular heat dissipation pipe. When in use, the notebook computer is put into the gap between the bottom plate and the space frame, the notebook computer is externally connected with a keyboard, the keyboard is placed in the space, and the keyboard is prevented from sliding down through the baffle. Connect the USB interface of the electric fan and the USB interface of the notebook computer through the USB cable, that is, supply power to the electric fan through the notebook computer. The natural wind blown out by the bottom plate and the space frame respectively through the through holes accelerates the heat dissipation of the notebook computer.

In the second embodiment shown in Figure 2, the space frame in the first embodiment is removed, and the notebook computer can be placed on the bottom plate for use without an external keyboard, and its usage method is the same as that of the first embodiment above. Simultaneously, as shown in Fig. 3 embodiment three, the structure of embodiment one also can be used in conjunction with adjustable support frame 4, and in Fig. 3 only return-shaped heat dissipation pipes are set on the base plate, and return-form heat dissipation pipes are not arranged on the space frame , It can also achieve the effect of cooling the notebook computer. According to Embodiments 1, 2, and 3 above, the range of the through holes on the circular heat dissipation pipe is ±45 degrees perpendicular to the bottom of the notebook computer and the space frame.
