Abstract
The utility model provides a microscale heat exchanger, relating to heat-exchange equipment with a microscale. The utility model is characterized in that a plurality of thin plates which are provided with cellular structures are combined together. The cellular structures are formed by sintering or other methods. So a flow channel of cold fluid and hot fluid is formed. The microscale heat exchanger not only has the characteristics of high heat transfer area of unit volume, low thermal resistance, small size, etc., but also can effectively overcome the defect that a micro channel is hard to process compared with a micro channel heat exchanger. The microscale heat exchanger has the advantages of simple structure, easy processing and better effect of heat transmission. The microscale heat exchanger can be widely used for the technical fields of microelectronic engineering technology, aerospace thermal environment control, material, biology, etc. The technical fields require small volume, light weight, high heat flow density, etc.
Description
The utility model belongs to a kind of heat transmission equipment, relates in particular to a kind of heat exchanger of miniature scale.
In recent years, since the microelectronic engineering technology, the development of the high, precision and frontier technology in fields such as space flight Thermal Environment Control and material, biology, and Microscale Thermal Phenomena is much accounted of gradually and studies.Therefore it is little, in light weight to have volume, compact conformation, and the minute yardstick heat exchanger of characteristics such as heat transfer area height and thermal resistance are little also begins one's study and uses.In the prior art usually the surface area space density greater than 5000m
2/ m
3Heat exchanger be called the minute yardstick heat exchanger, this kind heat exchanger is except being used for the cool electronic chip, also can successfully be used as utmost point subcolling condenser, the cooler of high-temperature superconductor, the cooler of intense laser beam and the fields such as thermal control system that are used for aerospace vehicle.At present, be used for the minute yardstick heat exchanger that two kinds of fluids carry out heat exchange in the prior art and also only limit to miniature conduit heat exchanger, this heat exchanger is the micro heat exchanger that is welded by many thin slices that have miniature conduit, and its heat-transfer effect is to improve along with reducing of minute grooves road size.Since the groove width of these small conduits and groove depth only tens microns to the hundreds of micron, this has just brought many inconvenience to processing and manufacturing, and the conduit size is more little, processing is just difficult more.
For overcoming deficiency and the defective that prior art exists, the purpose of this utility model and task are the minute yardstick heat exchangers that proposes a kind of loose structure, and this heat exchanger is not only simple in structure, and is easy to process, and heat-transfer effect is better.
The utility model is achieved through the following technical solutions: the runner of its cold and hot fluid is that the thin plate by loose structure combines, and between the thin plate of every loose structure metal partion (metp) is housed.The loose structure minute yardstick heat exchanger that adopts technique scheme and constitute, not only processing is simple, and because porous plate has strong perturbation action to flowing, very strong strengthening effect is played in heat transfer, thereby reached above-mentioned purpose effectively.
The utility model compared with prior art has the following advantages and beneficial effect: form because the runner of cold and hot fluid is a thin slice by loose structure, thereby overcome the unmanageable difficulty of small conduit in the miniature conduit heat exchanger effectively; Because loose structure has strong perturbation action to flowing, can play the effect of augmentation of heat transfer again, so the utility model compares with miniature conduit heat exchanger, its advantage be simple in structure, easy to process, heat-transfer effect is better.
Accompanying drawing 1 is the stereogram of minute yardstick heat exchanger.
Describe realization best way of the present utility model and specific embodiment in detail below in conjunction with accompanying drawing.
The utility model is that the thin plate of the loose structure that forms with sintering or alternate manner is combined, and forms the runner of cold and hot fluid, and sheet metal 3 is housed between the thin plate of every loose structure, as dividing plate.The structure of whole heat exchanger is mainly by cold fluid runner 1, hot fluid runner 2, and metal partion (metp) 3, import and export connector 4 and upper and lower cover plate 5 constitute.Generally, cold fluid runner and hot fluid runner should adopt chi structure, so that install and use.Its heat exchanger shape can be square, also can make other shape according to concrete needs.The sheet number of the size of heat exchanger and multihole lamina also can be selected arbitrarily according to actual conditions.Generally between 0.2～0.8, particle diameter is generally 0.1～1mm to the porosity of multihole lamina.
Claims (2)
1, a kind of minute yardstick heat exchanger, main cold and hot fluid runner and the import and export connector that is combined by the heat exchange thin slice constitutes, the runner that it is characterized in that above-mentioned cold and hot fluid is that the thin plate by loose structure combines, and metal partion (metp) [3] is housed between the thin plate of every loose structure.
2,, it is characterized in that cold fluid runner [1] and hot fluid runner [2] adopt chi structure according to the described minute yardstick heat exchanger of claim 1.
