Abstract
This invention discloses a radiator and its manufacturing method including: 1. punching strips to radiation fins, 2. bending the fins, 3. plugging the fins into a frame, 4. fixing the fins to a heat conduction plate, 5. removing remainders of the fins, 6. separating the frame to finish the formed fins with smaller thickness and increased radiation areas. Fins keep connecting with the remainders of the strip, only after segmentation and plug in the frame and fixed to the plate in one time, then the remainders are removed to smooth the fixing process, and the segmented fins are arrayed in space, thus flowing channels are intercrossed in many directions to speed up radiation.
Description
Technical field
The present invention relates to a kind of radiator and make forming method, particularly about a kind of by behind the facility installing radiating fin with the once affixed radiator of heat-conducting plate and make forming method.
Background technology
The performance performance of electronic equipment is whether the speed of its calculation process reaches user's demand, and influences in the factor of its arithmetic speed, and what primarily solve is the heat dissipation problem of its electronic building brick.Central processing unit with computer main frame panel is an example; the transmission of negative various instruction signals and the tasks such as computing of program numerical value because it is held concurrently; its frequency is exceedingly fast and produces high heat; so under the situation of high heat; the character of its electronic building brick will be influenced; and then the arithmetic speed of slowing down central processing unit; even termination action; cause user's work to carry out smoothly; especially network popularizes; during hang-up, whole network will be paralysed in case the central processing unit of share service device is overheated for it.Therefore, radiator is developed the heat radiation task that is applied to electronic building brick.
Known radiator sees also Fig. 1, comprises a heat radiation group 40 and a heat-conducting plate 50, and this heat radiation group 40 comprises radiating fin 41 and junction surface 42, and it is one-body molded in the mode of aluminium extruded type, again this junction surface 42 is fixed in this heat-conducting plate 50.See also shown in Figure 2ly, the heat radiation group 40 of this radiator is the radiating fin 41 ' that comprises separation, and a lateral edges of this radiating fin 41 ' is fixed in heat-conducting plate 50 '.See also shown in Figure 3ly, this heat radiation group 60 also comprises the radiating fin 61 of separation, and a side of heat-conducting plate 70 is provided with chase 71, and this radiating fin 61 plugs and is fixed in this chase 71.See also shown in Figure 4ly, this heat radiation group 60 ' is that the radiating fin 61 ' by punching press bending fastens serial connection and forms, and in addition one is fixed in heat-conducting plate 70 ' again.
Summary of the invention
Above-mentioned known radiator and manufacturing forming method thereof, as shown in Figure 1, if the thickness of radiating fin is too thin, the fashion of extrusion of aluminium extruded type makes radiating fin rupture when withdrawing pattern easily and loses and the moulding failure, therefore the radiating fin Thickness Design desire of this type radiator is little is difficult for, total cooling surface area is limited, can't reach better heat radiating effect.And for example shown in Figure 2, this radiating fin is bonding with heat-conducting plate again after the punch forming respectively, though compacting in advance by radiating fin, its thickness is reduced, promote total cooling surface area, yet during the bonding working expenditure of radiating fin, arrange accuracy and also need further control, do not meet the benefit of manufacturing.And as shown in Figure 3, though this heat-conducting plate has chase to establish stability and the accuracy that increases joint for groups of fins, still so its bonding time-consuming problem can't solve.Again as shown in Figure 4, this radiating fin obtains thin thickness with the pattern of punching press, arrange by it simultaneously in advance and fasten and be concatenated into the heat radiation group, once affixed entire heat dissipation group provides bigger total cooling surface area on heat-conducting plate, and easier affixed mode, yet the technology of radiating fin bending forming is various, when fastening the working expenditure of serial connection, and the doubt of pitching is arranged, and the airflow path that forms between the radiating fin is subject to single direction, can't fully heat be taken away rapidly.
As from the foregoing, above-mentioned known radiator and manufacturing forming method thereof on reality is made and in the use of this radiator, obviously have inconvenience and exist with shortcoming, are improved and hold.
So the inventor improves at above-mentioned shortcoming, propose a kind of reasonable in design and effectively improve the present invention of above-mentioned shortcoming.
