Abstract
Description
Technical Field
[0001] The utility model relates to the field of CPU heat dissipation, and more specifically, to a CPU heat sink. Background Art
[0002] CPU heat sinks have been developed as the CPU's main frequency and power have gradually increased. Early CPU chips had a power of less than 10W and did not require a heat sink for auxiliary heat dissipation. However, since the mid-1990s, as the CPU's main frequency has increased significantly, the CPU's power and heat generation have increased significantly. If the heat on the CPU cannot be discharged in time, within a limited space, it will seriously affect the CPU's working efficiency and may even cause irreversible damage.
[0003] In order to ensure the heat dissipation effect, the CPU radiator must be placed tightly against the CPU. For example, a Chinese utility model patent discloses a workbench for a centrifugal CPU copper-aluminum composite radiator (application number CN202220153521.0). A supporting mechanism is set up. Before connection, the user adjusts the sliding seat to slide toward the first connecting frame side to raise the connecting top seat. Then the user places the radiator body on the top of the connecting top seat and fixes the connection through bolts. After the connection is completed, the user pulls the sliding seat outward to disengage the pad from the bottom end of the second connecting frame. The compression spring pulls the radiator body downward under the action of elastic force, so that the pressing plate is pressed against the top of the CPU. However, this requires the CPU to bear the weight of the radiator body plus the tension of the compression spring. The CPU is easily crushed, and the compression spring pulling the radiator body will cause a collision between the pressing plate and the CPU, which can easily damage the CPU. Utility Model Content
