Description
Technical field
The present invention relates to heat transfer technology, more particularly to a kind of heat-exchanger rig and the semiconductor refrigerating with the heat-exchanger rig
Equipment.
Background technology
In recent years, semiconductor refrigerating equipment is widely used due to its superior performance, such as semiconductor freezer,
Semiconductor refrigerating refrigerator-freezer etc..Semiconductor refrigerating equipment realizes system using the automatic pressure-transforming Variable flow control technology of semiconductor chilling plate
It is cold, while radiating is realized by heat pipe and conduction technique, without refrigeration working medium and mechanical moving element.Therefore, semiconductor refrigerating
Equipment does not have the tradition machinery such as Working medium pollution and mechanical oscillation refrigeration plant applying upper a series of problems in application process.
However, while the cold end of semiconductor chilling plate produces cold, its hot junction can produce substantial amounts of heat.Semiconductor system
The heat in cold hot junction is the summation of its cold end refrigerating capacity and electrical power.Simultaneously as the hot junction area of semiconductor chilling plate is very
It is small, cause heat flow density very big.For example conventional TEC1-12708 size is 50*50mm, its maximum thermal power=electrical power
(12V*8A)+69W=165W；In view of mal-condition of environment temperature when high, it is necessary to ensure the heat-sinking capability of radiator at least
1.2~1.5 times of its maximum thermal power, about 198~247.5W.Because semiconductor chilling plate hot junction generates substantial amounts of heat,
To ensure that semiconductor chilling plate is reliably continued for work, it is necessary to be radiated in time to hot junction.
It is strong typically by setting blower fan to carry out radiating fin for the hot-side heat dissipation of semiconductor chilling plate in the prior art
The scheme of heat loss through convection processed, to improve heat exchange efficiency.But the defects of prior art is that radiating fin volume itself is larger, separately
Also axial flow blower need to be set in the side of radiating fin outside, with to the gap blow flow between two adjacent fins, or slave phase
Gap suction airflow between adjacent two fins.The volume of this heat exchanger is bigger, it is necessary to installing space is big, is not suitable for
Installed in less space.In addition, the hot-side heat dissipation of semiconductor chilling plate comes typically by the rotating speed and power of increase blower fan
Reach the purpose of radiating, radiating efficiency difference and the big high energy consumption of noise.
Also, prior art can not effectively solve the heat dissipation problem of the high semiconductor chilling plate of heat flow density, so that can not
Ensure semiconductor refrigerating ability.For example, the volume of conventional semiconductor freezer, which is generally less than, is equal to 50L, in environment temperature
For 32 DEG C when, ice the temperature inside the box can only pull down to 12 DEG C, can not realize lower temperature, lead to not to realize big volume that (volume is big
In 50L) semiconductor freezer.
