Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

As shown in fig. 1-4, the present invention provides a high efficiency heat sink, which comprises a heat sink body, wherein the heat sink body is provided with a base 1, a plurality of slots 2 with one ends inserted and fixed are uniformly distributed on the side surface of the base 1, fins 3 extending outwards are inserted into the slots 2, the fins 3 are provided with a plurality of heat dissipation holes 4, the base 1 is provided with a water trough 5 circulating inside, one side of the base 1 is provided with an injection interface 6 and a discharge interface 7 respectively connected with two ends of the water trough 5, the fins 3 are clamped into the slots 2 from one end of the base 1 and fixed, and do not protrude outwards and are level with the surface after being inserted, the number of the fins 3 is properly adjusted according to the practical use habit, the heat dissipation holes 4 are used to increase the contact area with air and enhance the air circulation speed, the length of one end of the base 3 connected with the fins is greater than the other end, the water flow flowing outside flows in the base 1 in a single direction, and cold water is injected into the base, so that the effect of absorbing internal heat is achieved, and the internal temperature is effectively reduced.

Fin 3 one end is equipped with joint to slot 2 inside fixed connecting portion 8, accompany conducting strip 9 between connecting portion 8 and the slot 2, connecting portion 8 are used for the joint to fix in slot 2 inside, because fin 3 has the thermal function of giving off, has utilized conducting strip 9 can be fast with the heat derivation of inside and give off through fin 3.
