The utility model relates to a heat sink of aluminum, copper, stainless steel, nickel-copper alloy, and carbon steel alloy. Especially the combined folding heat sink.
Various electronic devices have higher requirements for ambient temperature. Usually need to use a heat sink to quickly dissipate heat. The heat sink is used in the radiator to assist in heat dissipation. However, the existing heat sinks are all integrally formed in a planar shape. The heat sink is installed on the heat sink, and the shape of each heat sink is fixed. In this way, the heat sink cannot be adjusted according to various needs to improve the heat dissipation efficiency.
In view of the above-mentioned problems, the present invention provides a foldable heat sink. The foldable heat sink is used in a heat sink, and the heat sink can be unfolded or folded according to actual needs to improve the heat dissipation efficiency of the heat sink.
The technical scheme adopted by the utility model is:
The foldable heat sink includes a heat sink and a control piece. The heat sink includes a plurality of heat sink substrates, and the heat sink substrates are movably connected in sequence. Each heat dissipation substrate is provided with a through hole, and the control member passes through the through hole on the heat dissipation substrate. The control member includes a first control shaft and a second control shaft, and the second control shaft is movably sleeved in the first control shaft.
Each heat dissipating substrate includes a set of connecting members, and the connecting members include a first connecting element and a second connecting element. The first connection element and the second connection element are respectively arranged on an opposite side of the heat dissipation substrate. A plurality of heat dissipation substrates in the heat dissipation element are movably connected through the connection element.
The first connection element on each heat dissipation substrate is matched with the second connection element on the adjacent heat dissipation substrate. The second connection element on each heat dissipation substrate is matched with the first connection element on the adjacent heat dissipation substrate.
The first connecting element and the second connecting element on the adjacent heat dissipation substrates are connected by a shaft hole. In this way, the adjacent heat dissipation substrates can be relatively rotated, so that the heat dissipation substrates in the heat dissipation element can be folded into one body.
Each heat dissipation substrate is provided with at least one heat dissipation groove. The heat dissipation grooves are distributed on the two sides of each heat dissipation substrate, and the heat dissipation area is increased by the heat dissipation grooves, and the heat dissipation efficiency is improved.
The first control shaft includes a first shaft body and a first fixed end. The first shaft body is provided with a first shaft hole, and the second control shaft is sleeved in the first shaft hole. The first fixed end is provided at one end of the first shaft body. The first fixed end is clamped in the through hole of the first heat dissipation substrate in the heat dissipation member.
The diameter of the through hole is consistent with the diameter of the first shaft body. The diameter of the first fixed end is larger than the diameter of the first shaft body. In this way, when the first control shaft passes through the through hole on the heat dissipation substrate, the first fixed end is prevented from passing through the heat dissipation substrate, and the first control shaft is positioned on the heat dissipation substrate.
The second control shaft includes a second shaft body and a second fixed end, and the second shaft body is sleeved in the first shaft hole. The second fixed end is arranged at one end of the second shaft body, and the second fixed end is clamped in the through hole of the last heat dissipation substrate in the entire heat dissipation member.
The diameter of the second fixed end is larger than the diameter of the second shaft body. In this way, when the second control shaft passes through the through hole on the heat dissipation substrate, the second fixed end is prevented from passing through the heat dissipation substrate, and the second control shaft is positioned on the heat dissipation substrate.
Compared with the prior art, the beneficial effects of the present invention are: The utility model provides a folding heat sink. The folding heat sink is used in a heat sink. Adjacent heat sink substrates in the heat sink are connected by the first connecting element and the second connecting element. The heat dissipation substrates can rotate relatively, and the second control shaft is sleeved in the first control shaft. By changing the length between the second control shaft and the first control shaft, the heat sink can be expanded or folded according to actual needs, so as to improve the heat dissipation efficiency of the heat sink.
