Embodiment Construction

[0030] The technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0031] like figure 1 Shown, according to a specific embodiment of the present invention comprises:

[0032] Micro heat exchanger 1, first fluid joint 2, second fluid joint 3, first refrigerant joint 4, dry filter element 5, micro throttling element 6, the first Refrigerant circulation holes 7 , second refrigerant circulation holes 8 opened in a direction perpendicular to the side surfaces of the multi-layer metal sheet, and second refrigerant joints 9 . Among them, the micro heat exchanger 1 is an entity formed by multi-layer metal sheets (typically stainless steel sheets with a thickness less than 1mm) through vacuum diffusion welding, and forms interlaced refrigerant channels and heat exchange channels inside it. Fluid flow path. The plates of the miniature heat exchanger 1 formed by vacuum diffusion welding are...

Abstract

The invention provides an integrated micro heat exchanger which can complete drying filtering, throttling and phase-change heat transferring of a refrigerant in a single component and can be used as an evaporator and a condenser as well, and relates to an integrated micro heat exchanger component with drying filtering and throttling functions. The integrated micro heat exchanger component comprises a micro plate heat exchanger 1, a fluid connector 2, another fluid connector 3, a refrigerant connector 4, a drying filtering element 5, a micro throttling element 6, a refrigerant circulation hole 7, another refrigerant circulation hole 8 and a refrigerant connector 9. The micro plate heat exchanger 1 is an entity formed by arranging four plates, etched into flow passages of different shapes, according to a certain sequence prior to vacuum diffusion welding. The refrigerant circulation hole 7 and the refrigerant circulation hole 8 are formed by means of post processing in the side face direction after the micro plate heat exchanger 1 is welded together into the entity. The drying filtering element 5 and the micro throttling element 6 are mounted in the refrigerant circulation hole 7. The drying filtering element 5 is a molecular sieve filter formed by sintering, and the micro throttling element 6 is a short throttling pipe or a throttling orifice with micropores drilled in the middle.

Description

technical field [0001] The invention relates to an integrated heat exchanger assembly that can be used in a miniature vapor compression refrigeration system, which can complete the dry filtration, throttling and phase conversion heat of the refrigerant in a single assembly, and can be used as an evaporator or as an evaporator. Condensers are used to cool or heat fluids. When the invention is used in a miniature vapor compression refrigeration system, the volume and quality of the system can be effectively reduced, making the system more compact. Background technique [0002] The invention relates to vacuum diffusion welding technology, layered entity manufacturing technology (vacuum diffusion welding of multi-layer metal sheets), photochemical etching technology, miniature vapor compression refrigeration technology and compact heat exchanger technology. [0003] Vacuum diffusion welding is under the condition of high vacuum (the degree of vacuum is not less than 10 -2 Hold...
