Description

The present invention relates to a heat exhauster, and more particularly to an improved structure of a heat exhauster that enhances heat exhaust efficiency.

The heat exhauster is one of the heat exhaust members necessary in the electronics industry, and is used to eliminate waste heat generated by the electronic members. As shown in FIG. 1, a conventional heat exhauster usually includes a real metal bottom seat 10, and a plurality of metal heat exhaust fins 20 are coupled to the bottom seat 10. Affixed to the surface of the electronic member 30 and the waste heat generated during operation of the electronic member 30 is transmitted to the bottom seat 10 and further transmitted to the exhaust heat fin 20 to exchange heat with cold air, thereby eliminating the waste heat. However, when a large number of exhaust heat fins 20 are assembled to the actual metal base 10, the assembly structure is solid and precise, and the efficiency of heat conduction must be considered, and the exhaust heat fins 20 are relatively relatively. The cost of the structural design, manufacture and combination of the base 10 and the base 10 is increased, and for this reason, a heat exhauster configured by superimposing directly using heat exhaust fins appears on the market.

As shown in FIG. 2, in the heat exhaust apparatus configured to overlap using the direct heat exhaust fin, a sheet-shaped overlap unit 401 is provided at the same position of each heat exhaust fin 40. A heat exhaust fin portion 402 bent to one side, two sides, or the upper end of 401 is integrally formed, and thereby the overlapping portions 401 of several heat exhaust fins 40 are joined to each other so as to be joined together. A heat exhaust device having 403 is configured, and the bottom end face of the overlapping bottom seat 403 is used to contact the surface of the electronic member 30 to achieve the function of heat exhaust. A heat sink made using this type of superposition of exhaust heat fins 40 can overcome the technical problem of combining traditional heat exhaust fins 20 with a real metal bottom 10, but the superposition bottom 403 is not a real metal structure, but since the bottom end face of each overlapping portion 401 is actually attached to the surface of the electronic member 30, due to factors such as insufficient flatness of the bottom end face or a gap, The heat transfer efficiency between the electronic member 30 and the overlapping bottom seat 403 is impaired, leading to a decrease in overall exhaust heat efficiency.

The main object of the present invention is to allow the combined portion of the first exhaust heat fin to be attached to the electronic member by the structural design of the plurality of first exhaust heat fins and the second exhaust heat fin, and the combined portion exhausts heat. The present invention is to provide a heat exhauster that can transmit to a fin portion and transmit it to a second heat exhaust fin, thereby achieving the purpose of enhancing the heat exhaust area and heat exhaust efficiency.

The next object of the present invention is to connect a heat transfer tube (tube) to the merged portion of the first heat exhaust fin, and both ends of the heat transfer tube are extended to the second heat exhaust fin and combined therewith to enhance the heat exhaust efficiency. It is to provide a heat exhauster that achieves the purpose.

The first heat exhaust fins are stretched, the merged portions of the first heat exhaust fins are coupled to each other, and the heat exhaust fin portions are expanded relative to each other. The feature is that one or more convex pillars are provided at the upper ends of the exhaust heat fin portions of a plurality of first exhaust heat fins selected or specified in advance, and fixed above the exhaust heat fin portions. Two or more second heat exhaust fins overlapped with each other are joined, and the second heat exhaust fin is provided with a through hole corresponding to the convex column, and each convex column is joined through the through hole of the second heat exhaust fin. That's what it means.

A type of exhaust heat exchanger that enhances exhaust heat efficiency, which includes two or more first exhaust heat fins, the first exhaust heat fins are provided with merged portions, and the merged portions of the first fins are coupled to each other. An exhaust heat fin portion is provided on one side of the merged portion, the exhaust heat fin portions are expanded from each other, and one or more convex columns are provided at the upper end of the selected exhaust heat fin portion. One or more second heat exhaust fins are connected to the upper side of the heat exhaust fin portion by the convex column, and the combined portion of the first heat exhaust fins can connect the heat transfer tube, Both ends are extended and coupled to the second exhaust heat fin, thereby configuring a heat exhauster that enhances the exhaust heat efficiency.

With the improved structure of the exhaust heat generator that enhances the exhaust heat efficiency described above, the bottom end face of the merged part of the first exhaust heat fin is attached to the electronic member, and the waste heat during operation of the electronic member is transmitted to the merged part, and from the merged part Heat is transferred to the exhaust heat fin part of the first exhaust heat fin and the second exhaust heat fin, and heat is quickly transmitted from the heat transfer tube to the second exhaust heat fin, thereby increasing the exhaust heat area and improving exhaust heat efficiency.
