Embodiment 2

[0036] The working principle of Embodiment 2 is the same as that of Embodiment 1. The upper cover plate 2 is attached to the heat-generating components, and the upper and lower sides of the microchannel module 3 are respectively attached to the upper cover plate 2 and the manifold 4. The heat is obtained by a high heat generation rate. The heat-generating components are generated, and are transmitted to the upper cover plate 2 and the microchannel module 3 through heat conduction. At the same time, the cooling medium enters from the inlet pipe 1 at a certain speed, flows into the through hole 34 of the substrate 31 through the inflow hole 21, and then Flow through the inflow channel formed between the microgroove 33 on the top of the microchannel module 3 and the lower surface of the upper cover plate 2 through the edge of the through hole 34, and flow through the outlet flow formed between the microgroove 33 on the bottom of the microchannel module 3 and the inner bottom surfac...

Abstract

The invention relates to a disc-shaped radial micro-channel radiator. The radiator comprises an upper cover plate, a micro-channel module and a confluence plate. The upper cover plate is connected with the inlet pipeline, and the confluence plate is connected with an outlet pipeline; the upper cover plate and the confluence plate are connected, a cylindrical space is formed in the upper cover plate and the confluence plate, and the micro-channel module is arranged in the cylindrical space; and the micro-channel module structurally comprises a circular substrate, a through hole is formed in the middle of the substrate, a plurality of rib plates are formed on the upper surface of the substrate and radially extend from the edge of the through hole to the outer ring of the substrate, a micro-groove with a gradually increased flow section is formed between every two adjacent rib plates, and the upper surface of the substrate is attached to the upper cover plate, so an inflow channel is formed between the microgroove and the upper cover plate. The micro-channel radiator is used for solving the problem that an existing micro-channel radiator is not matched with annular and rotating parts, and the problem that the temperature is not uniform due to the fact that flow in the micro-channels is not uniform in the circumferential direction is solved through the outlet and the inlet which are formed in the radiator in the axis direction and the radial micro-channels.

Description

technical field [0001] The invention relates to a microchannel radiator, in particular to a disc-shaped radial microchannel radiator. Background technique [0002] Microchannel heat exchangers were first used in the field of electronic chips. With the advancement of science and technology and the development of processing technology, the degree of integration of electronic products is getting higher and higher, and the restrictions on the size of heat exchangers are becoming more and more strict. At the same time, with the improvement of the performance of electronic devices, their heat generation rate is also increasing. So people applied microtechnology to radiators. Microtechnology refers to the design, processing and operation of equipment under the condition of micro-scale space. The reasons why the micro-scale flow and heat transfer are different from the regular-scale flow and heat transfer can be divided into two categories: the first category is that the character...
