Abstract
The invention relates to a liquid-cooling heat exchanger with miniature mini-channel metal round tubes. The liquid-cooling heat exchanger comprises a heat exchanging mechanism, a coolant inlet tube, a coolant outlet tube, a heat exchanging mechanism, a cooling liquid container, a cooling liquid inlet tube and a cooling liquid outlet tube. The cooling liquid inlet tube and the cooling liquid outlet tube are arranged on a cooling liquid container. The liquid-cooling heat exchanger is characterized in that the heat exchanging mechanism is formed by connection of the coolant inlet tube and the coolant outlet tube through miniature mini-channel metal round tubes, and inner diameters of the miniature mini-channel metal round tubes are between 0.1mm and 0.4mm. The whole heat exchanging mechanism is arranged on the cooling liquid container. The liquid-cooling heat exchanger has the advantages that the miniature mini-channel metal round tubes serve as main heat exchanging mechanisms, so that the bearing pressure and the heat exchanging efficiency of the heat exchanger are improved.
Description
Technical field
The miniature microchannel metal circular tube liquid-cooling type heat exchanger of patent of the present invention, can be widely used in all radiator fields of Water cooled air conditioners and liquid-liquid heat exchange.
Background technology
What current family expenses and business air conditioner adopted is liquid-liquid heat exchanger (water-cooled), and what industrial central air-conditioning adopted is plate type heat exchanger.Because plate type heat exchanger is by the impact of its structure, very high pressure can not be born.Plate type heat exchanger is by the impact of mould simultaneously, and varying sized infusion of financial resources is comparatively large, and its miniaturized microminiaturized difficulty is huge.
Summary of the invention
The object of the invention is the deficiency in order to solve above-mentioned technology and to provide one to bear pressure high, applied widely, and the miniature microchannel metal circular tube liquid-cooling type heat exchanger of compact size.
In order to achieve the above object, miniature microchannel metal circular tube liquid-cooling type heat exchanger designed by the present invention, it comprises heat exchange mechanisms, refrigerant inlet tube, refrigerant exit pipe, heat exchange mechanisms, cooling liquid container, cooling liquid inlet pipe and coolant outlet composition, cooling liquid inlet pipe and coolant outlet are arranged on cooling liquid container, it is characterized in that described heat exchange mechanisms is connected and composed by miniature microchannel metal circular tube by refrigerant inlet tube and refrigerant exit pipe, and described miniature microchannel metal circular tube internal diameter is between 0.1 ~ 0.4mm, whole heat exchange mechanisms is arranged in cooling liquid container.The feature of this structure is to employ miniature microchannel metal circular tube as main heat exchange mechanisms, bears pressure and heat exchange efficiency with what improve heat exchanger.
In order to improve service life and heat exchange efficiency, be provided with at least two miniature microchannel metal circular tubes in described heat exchange mechanisms, and miniature microchannel metal circular tube is fixed by support or wire.
In order to improve the structural strength of heat exchange mechanisms, described miniature microchannel metal circular tube is connected with refrigerant inlet tube, refrigerant exit pipe by Welding Structure.
In order to improve heat exchange efficiency further, in described cooling liquid container, be provided with at least two heat exchange mechanisms.
In order to increase service life further, described heat exchange mechanisms is surperficial and cooling liquid container is surperficial is provided with corrosion proof and leakproof layer.
In order to reduce production cost further, reducing mechanism volume, described cooling liquid container is pipe, and two ends are by refrigerant inlet tube and refrigerant exit duct occlusion, and described cooling liquid inlet pipe and coolant outlet are arranged on the tube wall of pipe.
Miniature microchannel metal circular tube liquid-cooling type heat exchanger designed by the present invention, by using miniature microchannel metal circular tube, improve efficiency of heat exchanger, experiment proves, when microchannel diameter is less than 0.4mm, macroscopic theory formula is no longer applicable.Now the frictional resistance of miniature microchannel metal circular tube greatly reduces, and is about the 32%-42% of macroscopic theory value; Heat flow density is up to 100-150, and general traditional heat exchange form can only reach 10-20, and the thermal efficiency greatly improves, and can reach more than 0.95; Nu Saier coefficient (power of reflection convection heat transfer' heat-transfer by convection) reaches as high as 9.20, and traditional macro passage is up to 8.23.Meanwhile, can miniaturization be realized, microminiaturized, in same volume, be swapped out more heat, also there is volume little, lightweight, save material, can the feature of modularized production.
