Abstract

The utility model provides an enclosed type integral liquid cooling radiator, mainly comprising a water pump, fins and a soleplate. The utility model is characterized in that: same bores are punched on the center of each plate of fin, the bores are flanged, and then a plurality of fins and an axle center are stacked at together, and the flanged edges of the fins are mutually connected with the contacting position of the contiguous fin to make the centers of the fins form a cast path. One end of the cast path is connected with the water pump, and the other end of the cast path is connected with the soleplate to form a sealing chamber. The water pump is connected with a water inlet and a water outlet pipe whose external is coated with a heat-insulating layer, and the water outlet pipe and the heat-insulating layer are extended into the sealing chamber. The utility model which is applied to the radiating of an electronic component has the advantages of simple structure, large radiating area and good radiation effect.

Description

Closed whole liquid cooling heat radiator

Technical field:

The utility model relates to a kind of electronic component radiator, particularly relates to a kind of closed whole liquid cooling heat radiator that is used in computer CPU.

Background technology:

Along with the frequency of computer CPU is more and more higher, it produces a large amount of heats, if untimely with the heat discharge, will influence the stability of computer operation.Existing computer CPU radiator uses aluminium extruded to be pressed into usually, and the bottom is a square aluminum base plate, connects some radiating fins on the aluminum soleplate, and fan is installed on the fin; Because manufacturing techniques available, the spacing of fin is bigger, and number of fins is few, and area of dissipation is little, is difficult to reach the desirable radiating effect of CPU.Existing liquid cooling heat radiator all is split type, and is made of the radiating bottom plate that contacts with CPU, water tank, water pump and radiator coil tube, connects into the flow promoter system of circulation between them by water pipe, they have system complex, the many leakages easily of waterpipe jointing are installed inconvenience, the shortcoming that cost is high.

The utility model content:

At above-mentioned problems of the prior art, the purpose of this utility model provides a kind of closed whole liquid cooling heat radiator.Its spacing of fin is little, and area of dissipation is big, and radiating effect is good, and is simple in structure, easy for installation, and the metal material consumption is few, and cost is low.

In order to reach above-mentioned utility model goal of the invention, the technical solution of the utility model realizes as follows:

A kind of closed whole liquid cooling heat radiator, it mainly comprises water pump, fin, base plate, its design feature is: this every hole that the fin centre punch is identical, and the hole carried out flange, then some fin concentrics are stacked, interconnect at the flange of fin and the contact position of adjacent fins, make and be formed centrally tubular passageway in the fin; This tubular passageway one end connects water pump, and the other end connects base plate and forms closed inner chamber; Water pump is connected with water inlet and outlet pipe, and outlet pipe is surrounded by heat-insulation layer outward; Outlet pipe and heat-insulation layer stretch into closed inner chamber inside.

The utility model is owing to adopt above-mentioned closed whole liquid cooling heat radiator, compared following advantage with the radiator of prior art: use a spot of metal material, make the radiator of big area of dissipation, saved metal material, improve radiating efficiency, reached good radiating effect; Compare with existing liquid cooling heat radiator, closed whole liquid cooling heat radiator is simple in structure, easily manufactured, is easy to install, and can not produce leakage.
