The present invention relates generally to an interlaced heat dissipation structure, and more particularly to an interlaced heat dissipation structure of an addin card that helps lower a temperature of the addin card and achieve an effect of maximum heat dissipation area.
All sorts of substance exhibit electrical resistivity of different degrees, where electrical charges flowing in the substance are subjected to resistance that is similar to mechanical frictional force. Such a resistance force results from collision between electrons and atoms and this converts electrical power into thermal energy. Operations of electrical appliances may consume additional electrical power due to the generation of heat; however, the conversion of electrical power into thermal energy is not simply devoid of any merit. Depending on uses, some electronic equipment is operated on the basis of such characteristics of electrical resistance. For example, an electrical heater may be used to provide thermal energy so that the electrical heater is useful in keeping warm or heating water. For electronic equipment of computers, they consume a great amount of electrical power and may generate a lot of heat, causing an undesired rise of temperature of for example an addin card arranged in the electronic equipment. When the temperature of the addin card gets high, the operation of the addin card becomes unstable and in the worst situation, the addin card gets down and stops functioning, or may even lead to damage to the electronic equipment, or cause a fire and hurting users. Thus, it is important to provide a heat dissipation device on the addin card to lower down the temperature of the addin card.
Using a heat dissipation device may help effectively lower down the temperature of an addin card and keeps the addin card in normal operation. However, the heat dissipation device may involve heat dissipation fins that need to expand a contact area thereof with air to increase the efficiency of exchange of heat with air. Thus, the number of heat dissipation devices involved needs to be increased to expand the contact area thereof with air in order to make the heat dissipation performance better. However, using a large number of heat dissipation devices may result, adversely, the size of the electronic equipment in which the heat dissipation devices are installed, leading undesired inconvenience of a user for carrying and using.
Thus, it is a challenge of those devoted in this field to provide a solution to overcome such problems.
In view of the above problems and drawbacks, the present invention aims to provide an interlaced heat dissipation structure of an addin card that helps lower a temperature of the addin card and achieve an effect of maximum heat dissipation area.
The primary objective of the present invention is to provide a design of heat dissipation fins, cooling pipes, and heat dissipative elements to help lower down a temperature of an addin card.
Another objective of the present invention is to provide an interlaced design of cooling pipes and heat dissipative elements to allow the heat dissipative elements and the cooling pipes to be accommodated in a receiving to achieve an effective use of the space.
A structure that is adopted in the present invention to achieve the above objective generally comprises an addin card, wherein the addin card is provided with a plurality of heat dissipation fins thereon and the heat dissipation fins define therebetween at least one receiving space. The heat dissipation fins receive a plurality of cooling pipes extending therethrough for cooling the addin card. The receiving space receives a plurality of heat dissipative elements therein in a manner of being interlaced with the cooling pipes for cooling the addin card. As such, the heat dissipation fins, the cooling pipes, and the heat dissipative elements may absorb thermal energy from the addin card and increase a contact area with air to thereby increase the efficiency of heat exchange with air to achieve the purpose of dissipating heat from the addin card. Further, the cooling pipes and the heat dissipative elements are arranged in an interlaced manner in the receiving space defined between the heat dissipation fins to provide good heat dissipation performance within a limited amount of space.
With the above techniques, the problems and drawbacks of the prior art heat dissipation devices that the size is excessively large and causes inconvenience for a user to carry and use can be overcome and thus an advantage of improving utilization can be achieved with the present invention.
