Combined heat sink

The present invention relates to a combined heat dissipating unit, and more particularly to a combined heat dissipating unit having the effect of improving heat dissipation and configuring the number of heat pipes according to the user's anti-heating demand.

With the advancement of technology, the number of transistors per unit area of electronic components is increasing, causing an increase in the amount of heat generated during operation. On the other hand, the operating frequency of electronic components is also getting higher and higher. The heat caused by the on/off switching of the transistor is also the cause of the increase in the heat generated by the electronic components. If this heat is not properly handled, it will cause The reduction of the speed of the wafer operation may even affect the life of the wafer. To enhance the heat dissipation effect of the electronic components, it is necessary to use a passive heat sink and or a heat pipe and a temperature equalizing plate for heat conduction, so that the heat source is passed through the heat sink. The fins dissipate heat into the environment in a natural or forced convection manner to dissipate heat.

The above heat pipe can transfer a large amount of heat to a long distance for heat dissipation under a small cross-sectional area and a temperature difference, and can operate without an external power supply, without the need for power supply and space utilization economy. Underneath, various heat pipes have become one of the widely used heat transfer components in electronic heat dissipation products.

The most commonly used heat dissipation method is to install a heat-dissipating device (such as a heat sink) on the heat source, in particular, a heat sink having a heat pipe structure, which is made of a material having a high thermal conductivity. Then, through the working fluid and capillary structure provided in the heat pipe, the heat sink has the characteristics of high thermal conductivity, and the structure has the advantage of light weight, which can reduce the weight and cost derived from the heat sink. And the complexity of the system.

Since it is conventional to install a heat sink having a heat pipe structure on a heat source, the number and size of the heat pipes cannot be changed, and the user cannot adjust the number of the heat pipes according to the size of the heat source, so that the heat pipe cannot be elastically adjusted in use. In addition, the heat pipe cannot be used by itself or by a heat sink or a base to be assembled with the heat pipe, so that the heat source is first transmitted to the base or the heat sink and then transferred to the heat pipe. For remote heat dissipation, the heat pipe alone cannot be combined with the heat source to improve the heat transfer efficiency and the heat demand.

As mentioned above, the conventional disadvantages have the following disadvantages:

1. The number of heat pipes cannot be configured according to the user's heat dissipation requirements;

2. It is not possible to adjust the number of heat pipes according to the size of the heat source.

Therefore, how to solve the above problems and problems in the past, that is, the inventors of this case and the relevant manufacturers engaged in this industry are eager to study the direction of improvement.

Therefore, in order to effectively solve the above problems, the main purpose of the present invention is to provide a combined heat dissipation unit that can improve the heat dissipation effect.

The second objective of the present invention is to provide a combined heat dissipating unit that can adjust the number of heat pipes according to the size of the heat source.

In order to achieve the above object, the present invention provides a combined heat dissipating unit comprising at least one split body and a plurality of heat pipes, the split body having opposite joint portions, and the heat pipes are respectively closely coupled with the joint portions of the split body. The method or the welding method or the adhesive method is combined to form a large-area thermal contact surface.

Through the design of the structure of the creation, the user can adjust the number of heat pipes according to the heat wattage requirement of the user, or according to the size or quantity of the heat source, or according to the position of the plurality of heat sources. The distance between the heat pipes is different, and when the heat source has a large size or a plurality of heat sources are separated from each other, the plurality of split bodies and the heat pipes are staggered to form the combined heat sink unit. If the size of the heat source is small or the plurality of heat sources are close to each other, the user can reduce the number of the heat pipes and the split body, and the structure of the split body can be elastically made. The size of the combined heat sink unit is arbitrarily changed and the heat dissipation effect is improved.
