Description
Technical field
The invention belongs to special air-conditioning units refrigeration technology field, let cool or the heat exchange list of heat more particularly to a kind of quickly store
Member.
Background technique
Cold-storage thermal technology and equipment are making full use of for useless cold heat, and facilitate and realize staggering the time, easily for cold and hot amount
Ground is used and is come into being.Using phase transformation mode cold-storage or accumulation of heat, cooling capacity or heat are stored compared to the relatively conventional temperature difference mode that relies on
Amount, accounts in terms of reducing reservoir volume and has great advantage, especially in big cold and hot amount demand occasion.But phase transformation mode cold-storage heat
Equipment has a feature, due to phase-change material during the work time usually be in less stationary state, the usual very little of thermal coefficient, such as
If for it is cold and hot when the i.e. cold and hot output load of thermal velocity occasion of less demanding is small, the time is long to letting cool, problem is not when using
Greatly, but if it is desired to quickly it is difficult to release in time with cold and hot, very big cold-storage heat, this just affects pushing away for the hot equipment of cold-storage
It is wide to use, therefore study and quickly store that let cool hot equipment very necessary.
In view of the above-mentioned problems, structure function of the present invention by heat transfer manifold and heat exchanger plates, by one to as several pieces
Heat exchange unit composition, which stores, puts hot and cold heat exchange equipment, is placed in phase-change material, by being circulated through properly to each heat exchange unit
The cryogen of temperature, high temperature fluid, the phase-change material on the outside of heat exchange unit will gradually cold-storage and accumulation of heat；It is quick with realizing
It discharges, substantially increase the advantages of heat exchange area between two kinds of thermal mediums, effectively compensate for static phase transformation material thermal conductivity
Small the shortcomings that being unfavorable for flash heat transfer.
Summary of the invention
The purpose of the present invention is to provide a kind of quickly store to let cool or the heat exchange unit of heat, passes through heat transfer manifold, Yi Jihuan
The structure function of hot plate solves the disadvantage that existing static phase-change material thermal coefficient is small and is unfavorable for flash heat transfer.
In order to solve the above technical problems, the present invention is achieved by the following technical solutions：
The present invention lets cool for a kind of quickly storage or the heat exchange unit of heat, including heat transfer manifold and heat exchanger plates；

Liquid pipe and main drain pipe are separately fixed at heat transfer manifold both ends；
Wherein, the heat exchange branch pipe is fitted tightly on heat exchanger plates by welding manner or by processing methods such as extruding
It is inlayed integrally with heat exchanger plates.
Further, the heat transfer manifold and heat exchanger plates are all made of Heat Conduction Material；The Heat Conduction Material is steel or aluminium
Or copper material；The heat exchanger plates can only need to combine used phase transformation using conventional heat transfers materials such as aluminium, steel, copper materials
Compatibility, rotproofness, the cost of material are selected, without pursuing high thermal conductivity coefficient, because calculating whole heat transfer coefficient
When, influence very little of the thermal coefficient of material to overall heat-transfer coefficient.
Further, the heat exchange branch pipe is using circular tube structure or elliptical tube structure or rectangular tube structure.
Further, the heat exchanger plates use flat structure or fin plate profile structure；The fin plate profile structure packet
Include substrate and fin plate；The side of the substrate and heat exchange branch pipe is fixed with several diagonal rib sheets and several straight rib plates；
The diagonal rib sheet and straight rib plate are conducive to increase surface area, have and realize quick release, substantially increase two kinds of thermal mediums
Between heat exchange area the advantages of.
The invention has the advantages that：
The present invention is made up of one to heat exchange unit as several pieces structure functions of heat transfer manifold and heat exchanger plates
Storage puts hot and cold heat exchange equipment, is placed in phase-change material, by the low temperature stream for being circulated through suitable temperature to each heat exchange unit
Body, high temperature fluid, the phase-change material on the outside of heat exchange unit will gradually cold-storage and accumulation of heat；With realization quick release, sufficiently increasing
The advantages of having added the heat exchange area between two kinds of thermal mediums.
Certainly, it implements any of the products of the present invention and does not necessarily require achieving all the advantages described above at the same time.
