The course of work of above-mentioned two embodiment is: when semiconductor element entered the heat interpolation or migrates out described energy storage equipment, described energy storage equipment can be accumulated a large amount of heats or cold by described colloid shape material; When having fluid to pass through in the described coil pipe, the colloid of accumulating cold and hot amount will promptly be transferred to described fluid with cold and hot amount by described coil pipe, and the fluid that obtains cold and hot amount will flow to medical or the laboratory goes to carry out the exchange of cold and hot amount again with temperature equipment.
As shown in Figure 3, be the application schematic diagram of the above-mentioned Cooling and Heat Source of the present invention.4 is that circulating pump, 5 is that control system, 6 is that above-mentioned Cooling and Heat Source, 7 is cold and hot load among the figure; Connect into a circulatory system by pipeline between described Cooling and Heat Source 6, described cold and hot load 7 and the described circulating pump 4, described pipeline inserts the two ends of the coil pipe 32 of described Cooling and Heat Source 6, described cold and hot load 7 and described inlet of circulating pump and outlet respectively.Described control system 5 and described circulating pump 4, Cooling and Heat Source 6, cold and hot load 7 are electrically connected by lead; Control and regulate the flow of described circulating pump 4, cold and hot load 7, control the polarity of described Cooling and Heat Source 6 semiconductor elements.
Its course of work is: under the effect of control system, because the effect of circulating pump, when having fluid to pass through in the described coil pipe, the colloid of accumulating cold and hot amount will promptly be transferred to described fluid with cold and hot amount by described coil pipe, the fluid that obtains cold and hot amount will flow in the load, carry out the exchange of cold and hot amount with load, and then enter described coil pipe and repeat above-mentioned circulation.
Be example with two concrete medical or laboratories with temperature equipment below, illustrate described Cooling and Heat Source medical or laboratory with the application prospect in the temperature equipment.
One, with the sub-low-temperature therapeutic equipment is example
General sub-low-temperature therapeutic equipment comprises compressor cooling heating, accumulation of energy water tank, ice blanket and ice cap, and the intake-outlet of water tank joins through behind the water circulating pump with the intake-outlet of ice blanket and ice cap.The compressor cooling heating heats up the water in the water tank or cooling earlier when work, then the water in the water tank is flowed into described ice blanket and ice cap by water circulating pump, reaches the purpose of lowering the temperature or heating up to patient.Under the prerequisite of using compressor cooling, because the heat storage capacity of water is poor, large water tank is necessary; The weight that can make entire machine like this is more than 50 kilograms, and noise is more than 35 decibels, and volume is about 0.25 cubic metre.
If use Cooling and Heat Source of the present invention as Cooling and Heat Source being provided for the water in described ice blanket and the ice cap, because described colloid shape material can be accumulated a large amount of heats or cold, in coil pipe, there is the out-of-date meeting of current to make water for cooling rapidly, so can save large water tank, only need in described ice blanket and ice cap, to be filled with water and get final product; Utilize the semiconductor refrigerating element to replace compressor in addition, make the volume-diminished 2/3rds of whole sub-low-temperature therapeutic equipment; Weight has only the 5-6 kilogram; The noise of complete machine is only about 25.What this volume was little, in light weight, noise is little can ignore, and the convenient sub-low-temperature therapeutic equipment that moves and carry is bound to become the favorite of industry.
Two, refrigerated centrifuge
Refrigerated centrifuge in the past all uses compressor assembly as Cooling and Heat Source basically, solves because the rotary head of high speed rotation causes the problem that the temperature in the cavity raises.The weight of general whole freezing centrifuge about 40 kilograms, noise is more than 35 decibels, volume is more than 0.15 cubic metre.In addition, owing to the application of compressor assembly as Cooling and Heat Source, the general once pattern of refrigeration that adopts of described centrifuge directly is wrapped in copper pipe on the thin-wall metal cavity, is difficult to process; If use secondary refrigeration certainly, the problem that twines pipe on the metal thin wall cavity can be solved, but the large water tank cold-storage must be used again, can further increase its volume and weight, so also do not see at present.
Use Cooling and Heat Source of the present invention, can solve the problem of noise, weight and volume, make the volume-diminished 1/2nd to 2/3rds of whole freezing centrifuge; Weight has only original 1/3rd;
The noise of complete machine only about 25, almost can be ignored.Can solve simultaneously and copper pipe directly is wrapped on the thin-wall metal cavity problem of very difficult processing.
Above embodiment of the present invention can not be as limitation of the present invention; if those skilled in the art is under inspiration of the present invention; conspicuous improvement or distortion have been made; as; copper coil pipe is changed to aluminium matter coil pipe; change the quantity of semiconductor element and coil pipe etc., all should belong to protection scope of the present invention.
