Description

Technical Field

[0001] The utility model belongs to the technical field of heat sinks, and in particular relates to heat sinks with unequal spacing. Background Art

[0002] The heat sink is the main heat dissipation component of the radiator, which exchanges heat with the hot air flow in the casing to achieve heat dissipation. Most ordinary heat sinks have the same spacing, resulting in a consistent temperature field of the heat sink. Since the wind speed distribution of the fan is eccentric, ordinary heat sinks cannot effectively dissipate heat, and the cost of the heat sink is high and the heat dissipation efficiency is low.

[0003] In view of the above problems, Chinese patent CN 206974263 U discloses a heat sink with unequal spacing, which includes a heat sink base, a first heat sink unit, a heat sink, a heat sink slot and a second heat sink unit. The first heat sink unit is mounted on the heat sink base, the second heat sink unit and the first heat sink unit are composed of a plurality of heat sinks, the heat sink slot is mounted on the bottom of the heat sink base, and the heat sink cutout has an oblique angle. The utility model adopts the above technical solution to make the spacing of the heat sink unequal.

[0004] However, the above-mentioned heat sink is still fixedly arranged, which makes it inconvenient to adjust the spacing between the heat sinks and has a narrow application range. Utility Model Content

[0005] The utility model aims to provide a heat sink with unequal spacing. The spacing of the heat sink can be freely adjusted, and the utility model has wide applicability. The spacing of the heat sink can be freely changed according to different use environments.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a heat sink with unequal spacing, which includes a substrate, a through groove is provided on the substrate, a plurality of heat sinks are clamped inside the through groove, partition blocks are provided between the plurality of heat sinks, the partition blocks slide inside the substrate, and the number of partition blocks between two heat sinks can be adjusted.

[0007] Furthermore, a sliding groove is provided on the inner wall of the through groove, and the inside of the sliding groove is slidably connected to the heat sink.

[0008] Furthermore, the heat sink is slidably connected with a connecting rod near the substrate end, a spring is fixed to the connecting rod near the substrate end, the spring is fixed inside the substrate away from the connecting rod end, and a groove for the connecting rod is provided inside the substrate.

[0009] Furthermore, a wedge block is fixed to the connecting rod away from the spring end.

[0010] Furthermore, each of the partition blocks has an equal width, and a plurality of partition blocks are initially slidably connected inside each base plate.

[0011] The beneficial effect of the utility model is as follows: the utility model adopts the above-mentioned technical scheme to make the spacing of the heat sinks unequal. Since the wind speed of the fan is in an eccentric state, the part with stronger wind speed is blown to a denser spacing, and the part with lower wind speed is blown to a wider spacing, which greatly improves the heat dissipation efficiency and speeds up the heat dissipation. At the same time, in the utility model, the heat sink is installed on the base plate in a plug-in manner, which is convenient for disassembly and maintenance, and the spacing of the heat sink is determined by the number of partition blocks. The width of the partition blocks is set to be consistent, and the number of partition blocks between two heat sinks can be freely changed, thereby presenting heat sinks with different spacing combinations, which has a wide range of applications.

[0017] In order to further understand the content, features and effects of the utility model, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.

[0018] Please also refer to Figures 1 to 3 The heat sinks with unequal spacings according to the embodiment of the utility model will be described in detail below with reference to the accompanying drawings.

[0019] like Figure 1 As shown, the heat sink with unequal spacing includes a substrate 1, a through slot 2 is provided on the substrate 1, a plurality of heat sinks 3 are clamped inside the through slot 2, partition blocks 4 are provided between the plurality of heat sinks 3, the partition blocks 4 slide inside the substrate 1, and the number of partition blocks 4 between any two heat sinks 3 is adjustable.

[0020] A sliding groove 5 is provided on the inner wall of the through groove 2 , and the interior of the sliding groove 5 is slidably connected to the heat sink 3 .

[0021] In the present embodiment, the heat sink 3 and the substrate 1 are movably installed, and the spacing between the heat sinks 3 inside the substrate 1 is adjusted by the number of partition blocks 4, wherein the widths of the partition blocks 4 are equal, and each substrate 1 is initially slidably connected with a plurality of partition blocks 4, and the specific width dimension is determined according to actual needs. In the present embodiment, the width of the partition block 4 is 1.5 cm.

[0022] As an embodiment, a connecting rod 6 is slidably connected to the end of the heat sink 3 close to the substrate 1, a spring 7 is fixed to the end of the connecting rod 6 close to the substrate 1, the end of the spring 7 away from the connecting rod 6 is fixed inside the substrate 1, a content groove 8 for the connecting rod 6 is provided inside the substrate 1, and a wedge block 9 is fixed to the end of the connecting rod 6 away from the spring 7.

[0023] During specific use, the heat sink 3 is inserted into the through slot 2 of the substrate 1. When inserted, since the connecting rod 6 slides in the content slot 8 inside the heat sink 3, when the wedge block 9 contacts the through slot 2, the wedge block 9 and the connecting rod 6 slide toward the inside of the heat sink 3. At this time, the spring 7 is in a compressed state. After the connecting rod 6 and the wedge block 9 pass through the through slot 2, the spring 7 automatically returns to its initial state, and then the wedge block 9 contacts the bottom of the substrate 1 to fix the heat sink 3 in the vertical direction, and then the partition block 4 is pushed to the side of the heat sink 3 to contact the side of the heat sink 3, and then the next heat sink 3 is placed, and they are installed in sequence to complete the installation of all the required heat sinks 3.
