Description

External heat conductor

The invention relates to an external heat conducting member, in particular to an external heat conducting member for a heat dissipating device.

A hardware device such as a display card or a central processing unit is generally installed in a computer main body, and the above-mentioned hardware device generates a certain amount of thermal energy while being operated. The heat generated by the hardware device in the computer must be dissipated through a cooling fan, a heat sink, water cooling or a refrigerant.

The current mainstream cooling method is to dissipate heat through a combination of a cooling fan and a heat sink. The cooling fan and the heat sink system mounted on the hardware have a certain thickness. Therefore, when two or more hard bodies are mounted, there is not enough space between the hardware to allow air to flow because of the thickness of the heat radiating fan and the heat sink.

In general, in order to allow sufficient space between the various hardware devices for heat dissipation, a certain distance is reserved between the interface slots of the computer motherboard (for example, PCI or PCI-E). However, with the advancement of technology, the processing performance of the hardware device is relatively improved, and the thermal energy generated by the hardware device is relatively increased.

In order to cope with the increased thermal energy of the hardware device, it is naturally necessary to provide a more efficient means of dissipating heat from the hardware device. At present, the cooling fan and the heat sink are still mostly used as the mainstream. Therefore, in order to improve the heat dissipation efficiency, the heat dissipation fan and the heat sink are also required to increase the number and volume thereof, which also increases the thickness and volume of the hardware assembly, resulting in Computer equipment cannot be further miniaturized and does not meet current market trends.

Please refer to FIG. 1 for a stereoscopic combination diagram of a conventional display card. The conventional display card usually has a cooling fan and a heat sink for heat dissipation. However, if two display cards need to be assembled, the next display card will be in a close state, and the space between the two display cards is relatively small. And such a space does not allow the air to flow smoothly. Therefore, due to the slow or stagnant air flow, the thermal energy generated by the display card cannot be quickly taken away by the airflow, and the overheated display card may be thermally damaged or damaged.

Therefore, how to effectively utilize the space in the computer mainframe and prevent the thermal energy from accumulating on the electronic device, thereby preventing the heat or damage of the electronic device, is a problem that the relevant manufacturers engaged in the industry are eager to study and improve.

In view of this, in order to overcome the above problems and shortcomings, the inventors collected related materials, and through years of experience in the industry, through continuous experimentation and improvement, the invention patent of such external heat conducting parts was designed.

One of the objects of the present invention is to solve the problem of heat accumulation of an electronic device.

The connecting portion is disposed at opposite ends of the body, and the connecting portion is respectively connected to the heat pipe of the heat sink.

The utility model has the advantages that the heat dissipating device which can smoothly dissipate heat due to the narrow space can conduct heat to the other heat dissipating device through the external heat dissipating member, and dissipate heat through the other heat dissipating device. The external heat conduction member can effectively reduce the heat accumulation of the electronic device and prevent the electronic device from being hot or damaged.
