Definitions
- the invention relates to a technique for manufacturing a heat sink.
- a set of workpieces and a manufacturing method thereof are disclosed.
- a heat sink 15 has a mechanical connection to a supporting structure 11 (e.g. a housing) of a circuit board 17.
- the mechanical connection is the relative Position of the heat sink 15 in the system of support structure 11, printed circuit board 17 and component 16 to be cooled (also: component) is defined. This also defines the position of the heat sink base making contact with the component 16 .
- the heat sink base In order to thermally connect components 16 of different heights to the heat sink 15, the heat sink base must be processed during manufacture. This is done either subtractively, for example by milling as shown in FIG. 1, or additively, for example by applying spacer elements as shown in FIG.
- the heat sink base In order to install high components 16, the heat sink base must be very thick (as in the example in FIG. 1) and/or positioned within the support structure 11 at a great distance from the printed circuit board 17. The consequence of this is that for flat components 16 an unnecessarily large space, which could have served as a flow channel, for example, is built in with a thick heat sink base (as in the example in FIG. 2). In addition, the device is heavier as a result. Furthermore, the manufacture of the heat sink is complex, since the heat sink base must be adapted not only to the height of the component but also to the size and shape of the surface of the component.
- the invention is therefore based on the object of specifying a technique that can adapt a heat sink for components of different heights with less manufacturing effort.
- a workpiece set includes a support structure and a blank of a heat sink for fitting into the support structure.
- the support structure has an internal dimension for accommodating the fitted heat sink.
- the blank of the heat sink comprises a heat sink base which is designed to thermally contact an electrical component on a printed circuit board which is anchored or can be anchored in the supporting structure.
- the blank of the heat sink comprises a plurality of fins which, when received, have an extension in the direction of the inner dimension (eg, extend completely or partially parallel to the inner dimension or are partially angled relative to the direction of the inner dimension). At least a first fin of the fins extends (e.g., not necessarily in a straight line) a first dimension from the heat sink base in a first direction.
- At least a second rib of the ribs extends (e.g., not necessarily in a straight line). second dimension from the heatsink base in a second direction opposite the first direction.
- An overall dimension of the blank corresponds to the sum of the first dimension and the second dimension and is larger than the internal dimension of the support structure.
- the ribs are shortened or can be shortened in such a way that the sum of the first dimension and the second dimension corresponds to the internal dimension of the support structure and the first dimension and/or the second dimension defines a position of the heat sink base within the support structure.
- Exemplary embodiments of the workpiece set enable the position of the heat sink base of the heat sink in the overall system of the support structure and the printed circuit board, for example starting from the same blank, i.e. a non-component-specific blank, to be adapted to the varying requirements of components of different heights and/or different internal dimensions.
- Exemplary embodiments of the workpiece set enable a versatile use of uniform blanks due to the possibility of optionally rotating the blank by 180° when fitting it into the supporting structure (i.e. due to an optional assignment of which side of the supporting structure the first direction and the second direction are on), and the possibility of shortening in the first direction (i.e., on a first side) and/or in the second direction (i.e. on a second side).
- the position of the heat sink base can be determined by the first dimension and/or the second dimension.
- the position of the heat sink base within the support structure in the received state can be defined by the first dimension, the second dimension, or the difference between the first dimension and the second dimension. For example, if the heat sink base is in the middle within the support structure, the difference is equal to zero.
- a free end of the at least one first rib can rest on the inside of the support structure or be anchored in a form-fitting manner be.
- the position of the heat sink base within the support structure in the received state can be defined by the first dimension.
- a free end of the at least one second rib can rest on the inside of the support structure or be anchored in a form-fitting manner.
- the position of the heat sink base within the support structure can be defined by the second dimension in the received state.
- the free end of the at least one first rib and the free end of the at least one second rib can rest on the inside of the support structure, so that due to the mutually opposite first and second directions of the heat sink (at least in the direction of the ribs extending from the heat sink base) form-fitting is arranged in the supporting structure.
- the position of the heat sink base can correspond to a position of the electrical component within the support structure.
- the dimensions can each include a length dimension.
- the inner dimension of the support structure can correspond to an inner dimension of a free space in the support structure.
- the clearance may be configured to receive the heatsink, i.e. the fitted blank of the heatsink, for example along a transverse direction.
- the first direction and the second direction can be opposite to each other (also: antiparallel, i.e. parallel and oppositely oriented).
- the first direction and the second direction can be parallel to the inner dimension (e.g. in the recorded state).
- the heat sink base can be designed to thermally contact an electrical component for absorbing waste heat.
- the thermal contact can be direct mechanical contact or indirect mechanical contact via a thermal bridge.
- the heat sink base can directly or indirectly connect the electrical component, for example via a thermally conductive material (also known as thermal interface material or TIM).
- the heat sink base can make thermal contact with the electrical component via the printed circuit board.
- the heat sink base can make direct contact with the printed circuit board, with the electrical component being arranged on a side of the printed circuit board that faces away from the heat sink base.
- the electrical component can face the heat sink on the printed circuit board that is anchored or can be anchored in the support structure.

- the surface of the ridge can be exposed to the first direction and/or to the second direction.
- the web and adjacent second ribs may form or enclose (e.g. border) a flow channel in the support structure.
- the flow channel can be designed for convective cooling of the component. For example, due to a temperature gradient, air can flow in the flow channel counter to the direction of gravity (ie due to a chimney effect). Since the width of the ridge does not have to be adapted to the component, the width of the ridge can be smaller and/or the cross section of the flow channel larger (for example compared to conventional blanks or heat sinks for flat components).
- the web and/or the heatsink base can be arranged symmetrically in the blank or in the fitted heatsink with respect to the first direction and the second direction.
- the web and/or the heat sink base can be arranged asymmetrically with respect to the first direction and the second direction in the blank.

- the ribs 134 are shortened and/or the web 138 is exposed in sections to the first direction 136-1 for thermal contact with the component 160 (i.e. on the heat sink base 132), preferably in a milling process.
