The cooling liquid inlet pipe and the cooling liquid outlet pipe are arranged on the cooling liquid container. The minitype micro-channel metal round pipe liquid-cooled type heat exchanger is characterized in that the heat exchange mechanism formed by connecting the coolant inlet pipe and the coolant outlet pipe through a minitype micro-channel metal round pipe, the inner diameter of the minitype micro-channel metal round pipe ranges from 0.1mm to 0.4mm, and the whole heat exchange mechanism is arranged in the cooling liquid container. The minitype micro-channel metal round pipe liquid-cooled type heat exchanger has the advantage that the minitype micro-channel metal round pipe is used as the main heat exchange mechanism to improve the bearing pressure and the heat exchange efficiency of the heat exchanger.
Description
Technical field
The miniature microchannel metal circular tube liquid-cooling type heat exchanger of the utility model patent, can be widely used in all radiator fields of Water cooled air conditioners and liquid-liquid heat exchange.
Background technology
What family expenses and business air conditioner adopted at present 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 subject to the impact of its structure, can not bear very high pressure.Plate type heat exchanger is subject to the impact of mould simultaneously, and varying sized infusion of financial resources is larger, and the microminiaturized difficulty of its miniaturization is huge.
The utility model content
The purpose of this utility model is the deficiency in order to solve above-mentioned technology and provide a kind of pressure that bears 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, the miniature microchannel metal circular tube liquid-cooling type heat exchanger that the utility model is designed, it comprises heat exchange mechanisms, the refrigerant inlet tube, the refrigerant exit pipe, heat exchange mechanisms, cooling liquid container, cooling liquid inlet pipe and coolant outlet form, 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 characteristics of this structure have been to use miniature microchannel metal circular tube as main heat exchange mechanisms, with what improve heat exchanger, bear pressure and heat exchange efficiency.
In order to improve service life and heat exchange efficiency, be provided with many miniature microchannel metal circular tubes in described heat exchange mechanisms, and miniature microchannel metal circular tube is fixed by support or wire.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 further to improve heat exchange efficiency, be provided with at least two heat exchange mechanisms in described cooling liquid container.
In order further to increase service life, described heat exchange mechanisms surface and cooling liquid container surface are provided with the corrosion proof and leakproof layer.
In order further to reduce production costs, the 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.
The miniature microchannel metal circular tube liquid-cooling type heat exchanger that the utility model is designed, by using miniature microchannel metal circular tube, improve efficiency of heat exchanger, experiment showed, when microchannel diameter is less than 0.4mm, and the 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 the traditional macro passage is up to 8.23.Simultaneously, can realize miniaturization, microminiaturization is swapped out more heat in equal volume, also has a volume little, lightweight, saves material, but the characteristics that modularization is produced.
