Abstract
The invention provides a two-stage gradient heat transfer and exchange device and relates to the technical field of heat exchange equipment. The two-stage gradient heat transfer and exchange device is formed by sleeving two-stage pipelines with different diameter together. The two-stage pipelines comprise a first stage heat power bearing part pipeline with relatively large diameter and a second stage deep cooling part pipeline with relatively small diameter, a heat transfer medium B is injected into the second stage deep cooling part pipeline, a heat transfer medium A is injected between the first stage heat power bearing part pipeline and the second stage deep cooling part pipeline, and the saturation temperature of the heat transfer medium B is lower than that of the heat transfer medium A. Temperature gradient is set in the heat exchange device, so that heat transfer and conduction are realized by the single-layer medium, heat conduction and cooling also can be realized between the media, the phenomenon that excessive boiling is caused because the temperature rise of the heat transfer media is overhigh is avoided, and heat exchange efficiency is improved.
Description
Technical field:
The present invention relates to the heat-exchange apparatus technical field, relate in particular to a kind of two-stage gradient heat transfer heat exchanger.
Background technology:
The heat transmission of higher calorific power load bearing component and shift and manyly to take away heat with the metallic conduit transmission of internal circulation heat transfer medium is for example being accepted on the copper target that the high power laser light or the particle beams bombard the slugging copper pipe and is flowing through water flowing in copper pipe to take away heat.Copper pipe temperature and water temperature rise very soon when accepting the high power heat load, the water boiling, and when temperature continuation rising, when water changed transition boiling into from nucleate boiling, the heat flow density of the heat transfer of water reduced rapidly, heat transfer deterioration.At present, be employed in pipeline more and set up turbulence structure or change surface configuration, processing such as material increase heat-transfer capability, because these processing are based on heat transfer medium of the same race and single-stage is conducted heat, effect is limited.
Summary of the invention:
Technical problem to be solved by this invention is to overcome the defective of prior art; Provide a kind of heat exchange efficiency high two-stage gradient heat transfer heat exchanger; Set up thermograde in heat exchanger inside, not only realize single-layer medium heat transfer heat conduction, also can carry out heat conduction cooling between medium; Thereby avoid too fast transition boiling, the raising heat exchange efficiency of changing into of heat transfer medium temperature rise.
Technical problem to be solved by this invention adopts following technical scheme to realize.
A kind of two-stage gradient heat transfer heat exchanger; It is characterized in that: being nested together by the different two-stage pipeline sky of diameter constitutes; Said two-stage pipeline comprises one-level thermal power load bearing component pipeline and the less secondary degree of depth cooling parts pipeline of diameter that diameter is bigger; At the logical heat transfer medium B of secondary degree of depth cooling parts pipe interior,, logical heat transfer medium A between one-level thermal power load bearing component pipeline and secondary degree of depth cooling parts pipeline.
The saturation temperature of said heat transfer medium B is lower than the saturation temperature of heat transfer medium A.So just set up thermograde in heat exchanger inside; Realize that not only one-level thermal power load bearing component pipeline is to heat transfer medium A single-layer medium heat transfer heat conduction; Also can realize heat transfer medium A is carried out heat conduction cooling between medium through heat transfer medium B; Thereby avoid too fast transition boiling, the raising heat exchange efficiency of changing into of heat transfer medium A temperature rise.
The present invention sets up thermograde in heat exchanger inside, not only realizes single-layer medium heat transfer heat conduction, also can carry out between medium the heat conduction cooling, thereby avoids the heat transfer medium temperature rise too fast and change transition boiling into, improves heat exchange efficiency.
Description of drawings:
Fig. 1 is a structural representation of the present invention.
The specific embodiment:
For technological means, creation characteristic that the present invention is realized, reach purpose and effect and be easy to understand and understand, below in conjunction with concrete diagram and embodiment, further set forth the present invention.
As shown in Figure 1; A kind of two-stage gradient heat transfer heat exchanger; Be nested together by the different two-stage pipeline sky of diameter and constitute; Said two-stage pipeline comprises one-level thermal power load bearing component pipeline (1) and the less secondary degree of depth cooling parts pipelines (2) of diameter that diameter is bigger, at the inner logical heat transfer medium B (4) of secondary degree of depth cooling parts pipelines (2); Logical heat transfer medium A (3) between one-level thermal power load bearing component pipeline (1) and secondary degree of depth cooling parts pipelines (2), the saturation temperature of heat transfer medium B (4) is lower than the saturation temperature of heat transfer medium A (3).
Embodiment
Selecting deionized water for use is heat transfer medium A (3); Selecting liquefied ammonia for use is heat transfer medium B (4); The saturation temperature of heat transfer medium B (4) is lower than the saturation temperature of heat transfer medium A (3) under uniform pressure; So just set up thermograde, not only realized one-level thermal power load bearing component pipeline (1), also can realize heat transfer medium A (3) is carried out heat conduction cooling between medium through heat transfer medium B (4) to heat transfer medium A (3) single-layer medium heat transfer heat conduction in heat exchanger inside; Thereby avoid too fast transition boiling, the raising heat exchange efficiency of changing into of heat transfer medium A (3) temperature rise.
More than show and described basic principle of the present invention and principal character and advantage of the present invention.The technical staff of the industry should understand; The present invention is not restricted to the described embodiments; That describes in the foregoing description and the specification just explains principle of the present invention; Under the prerequisite that does not break away from spirit and scope of the invention, the present invention also has various changes and modifications, and these variations and improvement all fall in the scope of the invention that requires protection.The present invention requires protection domain to be defined by appending claims and equivalent thereof.
