Description
Technical field
The utility model relates to fluid thermal exchange heat transfer technology field, particularly a kind of temperature control system.
Background technology
In industry fields such as Aero-Space, data center, biologic medical apparatus and precision instrument, temperature control is direct and keep the safety in production, enhance productivity, guarantee that economic and technical norms such as product quality and energy savings are closely bound up.Moreover, we also be unable to do without temperature control everywhere in daily life, such as heating, refrigeration, hot water supply etc.At present, being used for temperature controlled mode has steam compression type, semiconductor cooled and gases at high pressure expansion type etc., because steam compression type adopts the latent heat heat exchange, heat flow density is big, efficient is high and it is convenient to detect control, therefore is widely used in the engineering reality.
Existing steam compression type heat-exchange system is made up of heat exchanging piece such as compressor, condenser, expansion valve and evaporimeters usually; Through pipeline they are connected into a closed system; Its operation principle is: refrigerant liquid in evaporimeter with the low temperature and the object generation heat exchange that is cooled; Absorption the be cooled heat and the gasification of object, the low-pressure steam of the generation machine that is compressed sucks, and discharges with high pressure after compression; The high-pressure gaseous refrigerant that compressor is discharged gets into condenser by the cooling water of normal temperature or air cooling and then condense into highly pressurised liquid; By throttling, the gas-fluid two-phase mixture that becomes low-pressure low-temperature got into evaporimeter when highly pressurised liquid was flowed through expansion valve; Liquid refrigerant in gas-fluid two-phase mixture sweat cooling in evaporimeter, the low-pressure steam of generation are compressed machine once more and suck, and circulation so goes round and begins again.This shows; The exchange capability of heat of steam compression type heat-exchange system is directly related with the pressure ratio of the flow of cold-producing medium and compressor, therefore if will improve exchange capability of heat, or strengthens refrigerant flow; Improve the pressure ratio of compressor; But strengthen the diameter that refrigerant flow will add large pipeline usually, the pressure ratio that improves compressor need select then that volume is big, the higher compressor of power, and these two kinds of methods all can increase the overall dimensions of heat-exchange system.Yet current people more trend towards the compact temperature control system of compact conformation, so the high miniaturization temperature control system of exchange capability of heat becomes new research direction.
In order in reduced size, to realize bigger exchange capability of heat; Chinese patent CN1567580A discloses a kind of mini-refrigerator system that is used for the computer chip heat radiation; Its structure is: compressor links to each other with condenser; Condenser links to each other with capillary and evaporimeter through device for drying and filtering, and evaporimeter is connected with compressor to form refrigerating circuit through liquid separatnig tube; Evaporimeter is that parallel/series or connection in series-parallel are connected between device for drying and filtering and the liquid separatnig tube with mixing and are connected single-stage or the multi-stage evaporator on the pipeline, and capillary is connected on the preposition connection pipeline of each evaporimeter.Though above-mentioned refrigeration system can realize the exchange capability of heat of expection under small size; But exist following deficiency: 1. because the pipeline diameter of this refrigeration system is thin and crooked more; Difficulty is big when mounted; Especially the position that is connected with other heat-exchanging components of pipeline supplies the space of assembling tool operation very little, and installation difficulty is very big; 2. this refrigeration system is mainly used in the heat radiation of computer chip; For the normal operation that guarantees that this system can other electronic components of interference calculation machine, need elements such as compressor, condenser, cooling fan, device for drying and filtering, capillary, liquid separatnig tube, control circuit be relied on and technology such as weld, withhold and be integrated in the refrigerator casing refrigerator parts of an integral body of formation; And in order to satisfy the dimensional requirement of computer; The size of these refrigerator parts cannot be excessive, if wherein certain heat-exchanging component is damaged, the maintenance personal need detect, dismantle and change this element in narrow and small space; Operation easier is very big; Therefore requirement to the maintenance personal is also very high, in order to save time and cost, though still all the other heat-exchanging components are intact can normally use; But method commonly used all is directly to change whole refrigeration system, has caused waste to a certain extent.
The pipe-line system operating space is little in order to solve, installation difficulty is big and be not easy to change separately the problem of a certain heat-exchanging component; Chinese periodical document " light Duty Design of Hydraulic Manifold " (is permitted on the sunny side; " hydraulic pressure and pneumatic " second phase in 2007, P36) discloses a kind of hydraulic integrated valve block; Its welding through steel pipe in the metal framework of hollow makes up runner; And in frame inner wall casting type for example light materials such as magnadure are with fixing each fluid pressure line and agents enhance overall intensity, runner leaves a hole near the position at metal framework edge, inserts for all kinds of valves.
If the method for above-mentioned hydraulic integrated valve block structure runner directly is used to make up the pipe passage of temperature control system; Then can have following problem: 1. this hydraulic integrated valve block has been reserved the hole that is suitable for inserting all kinds of valves on runner; But above-mentioned hole is self-existent single hole; The valve that is suitable for inserting also is confined to control runners such as stop valve, shutoff valve and opens and closed simple valve body, and used heat-exchanging component need be discharged cold-producing medium drainage to element internal in the follow-up pipeline of entering mostly again in temperature control system; The interface that is to say heat-exchanging component is generally 2 or more a plurality of; Therefore directly use the single hole inserted mode that above-mentioned hydraulic integrated valve block provided, can't realize being communicated with of pipeline and heat-exchanging component, also just can't realize the heat exchange function of heat exchanger; 2. for gaining in strength; Above-mentioned hydraulic integrated valve block runner construction method will be to the inner magnadure of filling of valve piece; Yet because there is the big temperature difference in the cold-producing medium of heat-exchange system at the diverse location of passage, if directly use said method structure pipeline and fill magnadure, magnadure can produce the heat conduction; Make the temperature phase mutual interference between the different pipelines, have a strong impact on the thermal efficiency of heat-exchange system.
In sum, still can not solve the problem that compact temperature control system installation difficulty is big, be not easy to change separately a certain heat-exchanging component in the prior art.
