2) Semiconductor refrigeration piece 8 has two length wide surfaces, and a length wide surface (cold side) is used for the refrigeration, and another length wide surface (hot side) is used for the heat dissipation, and in fact, to realizing that semiconductor refrigeration piece 8's long-time normal work does not damage, guarantee that the good of semiconductor refrigeration piece 8's hot side, fully, enough dispel the heat is first order, guarantee on the contrary that the good refrigeration of semiconductor refrigeration piece 8's cold side is second order.

In view of the refrigeration principle of the semiconductor refrigeration piece 8, the heat of the hot surface of the semiconductor refrigeration piece 8 must be actively and fully radiated, so that the whole semiconductor refrigeration piece 8 is prevented from being burned out due to overheating of the hot surface.

Therefore, in the prior art, generally, the heat radiating fins are arranged on the hot surface of the semiconductor chilling plate 8, then the heat radiating fan is arranged on the heat radiating fins, because the hot surface of the semiconductor chilling plate 8 is in direct contact with the heat radiating fins, the heat on the hot surface of the semiconductor chilling plate 8 is transferred to the heat radiating fins, the heat radiating fan rotates to generate cooling air, the cooling air passes through the surface of the heat radiating fins, and the heat on the hot surface of the semiconductor chilling plate 8 is finally taken away by the cooling air generated by the heat radiating fan, so that the heat radiation of the hot surface of the semiconductor chilling plate 8 is realized.

Above-mentioned, the heat dissipation to the hot side of semiconductor refrigeration piece 8 is the heat convection formula heat dissipation that the air flows through heat radiation fins, and semiconductor refrigeration piece 8 is the rigid among the prior art, and heat radiation fins is also the rigid, and sets up an axial fan simultaneously and carries out convulsions to heat radiation fins for the air flows to get up and passes through from heat radiation fins's surface, takes place heat convection formula heat dissipation, so mainly has following 4 defects: (1) the volume of the semiconductor refrigeration piece 8 is very small, the thickness is 3 mm-5mm, for example, the length is 40mm × the width is 40mm × the thickness is 3.5mm, but compared with the volume of the semiconductor refrigeration piece 8, the volume of the heat dissipation fin and the heat dissipation fan is too large, the sum of the volumes of the heat dissipation fin and the heat dissipation fan is dozens or even hundreds of times of the volume of the semiconductor refrigeration piece 8, the proportion of the volumes is very inconsistent, and the volume is too large, and the larger the refrigeration capacity of the semiconductor refrigeration piece 8 is, the larger the heat dissipation capacity of the matched heat dissipation fin and the heat dissipation fan is, the larger the sum of the volumes of the matched heat dissipation fin and the heat dissipation fan is, which corresponds to the technical problem that the refrigeration capacity of the semiconductor refrigeration assembly in the prior art is enough but the volume is too large or the volume can be put into but the refrigeration capacity is not enough when being used on a CPU: for example, a semiconductor cooling plate 8 with 60W cooling capacity is required for a CPU to radiate heat well and sufficiently, but the volume of a 160W heat dissipation fin and a heat dissipation fan is too large to be placed in a host case of a computer, so that there is not enough space for installation, so at this time, the sum of the volume of the heat dissipation fin and the heat dissipation fan is controlled, and a heat dissipation fin and a heat dissipation fan which are small in volume and can be placed in the host case of the computer are selected, for example, an 80W heat dissipation fin and a heat dissipation fan are selected, and then a semiconductor cooling plate 8 which is matched with the heat dissipation fin and the heat dissipation fan is selected, for example, a 30W cooling semiconductor cooling plate 8 is selected, and it is obvious that the 30W cooling semiconductor cooling plate 8 is not enough to radiate heat well and sufficiently for the CPU, but there is no method, firstly, the volume is allowed to be put into a host case of a computer, and if the volume is too large, the refrigerating capacity cannot be put into the host case, and the refrigerating capacity is enough;

(2) the heat really needs to be dissipated by the hot surface of the semiconductor refrigerating sheet 8, but the cooling air directly blows the heat dissipating fins, the cooling air does not directly blow the hot surface of the semiconductor refrigerating sheet 8, the heat dissipating fins are separated between the cooling air and the hot surface of the semiconductor refrigerating sheet 8, like a first-level medium is separated between a buyer and a seller, the price difference is earned by an intermediary, the first-level thermal resistance is increased by increasing the first-level medium in the middle of the heat transfer process, the total heat transfer efficiency is reduced, and the heat dissipating effect and the heat dissipating efficiency of the hot surface of the semiconductor refrigerating sheet 8 are reduced;

(3) cooling air (air) only lightly sweeps over the surfaces of the heat dissipation fins, and the convection strength is low, so that the heat dissipation effect and the heat dissipation efficiency are low;

(4) the heat dissipation fins in the prior art are always in a passive state with equal wind, the amount of the wind is not controlled, the heat dissipation fins are always in an equal, reliable and necessary passive state with the initiative in the heat dissipation fan, the heat dissipation fins are not actively struggled not to actively knock out the heat dissipation fins, the heat dissipation fins wait for the wind quietly, and like people do nothing in life, the passive attitude such as the passive attitude and the necessary attitude can cause passive idling, low efficiency and difficult success, and the heat dissipation effect and the heat dissipation efficiency of the hot surface of the semiconductor refrigeration sheet 8 are also lower.

Therefore, how to improve the heat dissipation effect and the heat dissipation efficiency of the hot surface of the semiconductor cooling plate 8 is a technical problem that needs to be solved urgently by those skilled in the art.

Therefore, the application creatively provides a novel heat dissipation mode of the hot surface of the semiconductor refrigeration sheet 8: the semiconductor refrigeration piece is fixed on the rotary metal heat conduction piece, the method is similar to the method that wet clothes are directly tied on the rotating blades in the fan blades of a ceiling fan, the hot surface of the semiconductor refrigeration piece 8 is directly exposed, the hot surface of the semiconductor refrigeration piece 8 is not covered by any object except aluminum strips, the hot surface of the semiconductor refrigeration piece 8 is directly exposed in the atmosphere and directly contacted with air, and the semiconductor refrigeration piece 8 rotates to be like the method that the semiconductor refrigeration piece is tied and fixed on the rotating blades in the ceiling fan to rotate together, the rotating semiconductor refrigeration piece 8 has kinetic energy and can do work on the air, the hot surface of the rotating semiconductor refrigeration piece 8 can extrude, cut, rub and stir the air, so that the hot surface of the semiconductor refrigeration piece 8 directly conducts heat with the air in a heat convection mode, and the heat on the hot surface of the semiconductor refrigeration piece 8 is transferred to the air, then the heat is taken away by the air, so that the working principle of radiating the hot surface of the semiconductor refrigeration piece 8 in the application is realized, and the application realizes good and sufficient heat radiation of the hot surface of the semiconductor refrigeration piece 8.

The application adopts the novel heat radiation mode of the hot surface of the semiconductor refrigerating sheet 8 to obtain the following beneficial technical effects:

(a) after the novel heat dissipation mode of the hot surface of the semiconductor refrigeration piece 8 is adopted, a large-size heat dissipation fin and a heat dissipation fan do not need to be arranged on the hot surface of the semiconductor refrigeration piece 8, and the refrigeration function and the heat dissipation function can be realized only by one thin semiconductor refrigeration piece 8, so that the volume of the refrigeration assembly is remarkably reduced, the refrigeration assembly is favorable for being installed and used in a narrow space, and the technical problems that the refrigeration amount of the semiconductor refrigeration assembly in the prior art is enough but the volume is too large and cannot be put into the refrigeration assembly or the volume can be put into the refrigeration assembly but the refrigeration amount is not enough are solved;

(b) the hot surface of the semiconductor refrigeration piece 8 is directly exposed in the atmosphere and is directly contacted with the air, and the semiconductor refrigeration piece 8 is rotated, so that the hot surface of the semiconductor refrigeration piece 8 can directly generate heat convection type heat transfer with the air, a heat transfer medium such as a heat dissipation fin is not arranged between the hot surface of the semiconductor refrigeration piece 8 and the air, and a thermal resistance generated by the medium is not arranged, so that the heat dissipation effect and the heat dissipation efficiency of the hot surface of the semiconductor refrigeration piece 8 are improved;

(c) the application leads the hot surface of the semiconductor refrigeration piece 8 to be directly exposed in the atmosphere and directly contacted with the air, and leads the semiconductor refrigeration piece 8 to rotate, just like binding and fixing the semiconductor refrigeration piece on the rotating blade in the ceiling fan to rotate together, the rotating semiconductor refrigeration piece 8 has kinetic energy and can do work to the air, the hot surface of the rotating semiconductor refrigeration piece 8 can extrude, cut, rub and stir the air, thereby obviously improving the heat convection intensity between the hot surface of the semiconductor refrigeration piece 8 and the air, obviously improving the heat transfer efficiency of the heat transfer on the hot surface of the semiconductor refrigeration piece 8 to the air, therefore, more heat can be transferred to the air in unit time and further taken away by the air, and improving the heat dissipation effect and the heat dissipation efficiency of the hot surface of the semiconductor refrigeration piece 8, the heat dissipation effect and the heat dissipation efficiency of the semiconductor refrigerator are improved finally;

for example, it is all the more true that, if a T-shirt is washed in summer, the washed T-shirt is aired indoors, and the room is naturally ventilated, and the T-shirt is aired completely, the time is generally 10 hours; further, if the washed T-shirt is wrapped with a layer of water-absorbing dry sponge and then placed under an indoor ceiling fan, the wind generated by the ceiling fan blows directly towards the dry sponge, and the wet T-shirt can be dried completely for 5 hours; furthermore, if the washed T-shirt is tightly bound on the blades in the fan blades of the ceiling fan, the wet T-shirt rotates along with the blades of the ceiling fan, and the complete drying may only need 1-2 hours; the principle is convection drying, but the convection intensity is gradually improved, so that the drying time is gradually and obviously reduced;

the semiconductor refrigerating sheet 8 in the application is just like the wet T-shirt which is just washed and has water, and the layer of water-absorbing dry sponge wrapping the wet T-shirt is just like the heat dissipation fins on the hot surface of the semiconductor refrigerating sheet 8 in the prior art;

in the prior art, the semiconductor refrigerating sheet 8 is fixed, the radiating fins are also fixed, and an axial flow fan is arranged to exhaust air to the radiating fins, so that air flows through the surfaces of the radiating fins to generate heat convection type heat dissipation, namely the washed T-shirt is wrapped by a layer of water-absorbing dry sponge and placed right below an indoor ceiling fan, and then the air generated by the ceiling fan is blown directly towards the dry sponge, so that the heat convection intensity is low, and the heat dissipation effect and the heat dissipation efficiency of the hot surface of the semiconductor refrigerating sheet 8 are low;

the semiconductor refrigerating sheet is arranged on the long and wide surface of the metal heat conducting sheet and rotates along with the metal heat conducting sheet, the hot surface of the semiconductor refrigerating sheet 8 is directly exposed in the atmosphere and rotates, the hot surface of the semiconductor refrigerating sheet 8 actively blows out to squeeze air, shear air, friction air and stir air, the washed T-shirt is tightly bound on blades in blades of a ceiling fan, the wet T-shirt rotates along with the blades of the ceiling fan, the heat convection strength is obviously improved, and the heat dissipation effect and the heat dissipation efficiency of the hot surface of the semiconductor refrigerating sheet 8 are obviously improved;

(d) the semiconductor refrigerating sheet 8 is rotated, the hot surface of the semiconductor refrigerating sheet 8 is actively knocked out to extrude air, cut air, friction air and stir air, the active knocking out is used for generating air and capturing air, the active knocking out is used for some reason, the situation is not equal, and is not required, and the heat radiation fan is not required to provide air for the semiconductor refrigerating sheet 8, the wind comes and the amount of the wind comes are controlled by the semiconductor refrigerating sheet 8, the active right is firmly controlled at the semiconductor refrigerating sheet 8, and the active knocking out is actively performed, so that the heat radiation effect and the heat radiation efficiency of the hot surface of the semiconductor refrigerating sheet 8 are obviously improved.

3) In the actual use process of the semiconductor refrigerating sheet 8, when the refrigerating capacity of a single semiconductor refrigerating sheet 8 is larger and cannot meet the actual requirement, a plurality of semiconductor refrigerating sheets 8 are used for refrigerating together.

The semiconductor refrigerating sheet 8 is a plane sheet, so that the semiconductor refrigerating sheet cannot be folded or bent; furthermore, in view of the refrigeration principle of the semiconductor refrigeration sheet 8, in the prior art, a plurality of semiconductor refrigeration sheets 8 are not usually overlapped together for refrigeration, although the overlapping is feasible in principle, the operation is difficult in reality, and the semiconductor refrigeration sheets 8 consume large electric energy and are not paid, so that the significance is not great; therefore, in order to realize the common refrigeration of the plurality of semiconductor refrigeration sheets 8 in the prior art, usually, the plurality of refrigeration assemblies are simply and repeatedly arranged, each refrigeration assembly comprises 1 semiconductor refrigeration sheet 8 and a heat radiation fin and a heat radiation fan which are matched with the semiconductor refrigeration sheet 8, the final assembled finished product has a large volume due to the repeated arrangement, for example, if 4 semiconductor refrigeration sheets 8 are needed for refrigeration, 4 heat radiation fins and 4 heat radiation fans must be matched, the volume is too large, the semiconductor refrigeration sheets 8 cannot be installed in a general installation space, and the popularization and application of the common refrigeration of the plurality of semiconductor refrigeration sheets 8 in the industry are severely limited.

Therefore, how to set several semiconductor refrigeration pieces 8 in a limited crowded installation space in practical application, a plurality of semiconductor refrigeration pieces 8 can refrigerate together, so as to improve the total refrigeration capacity (namely, improve the total refrigeration capacity of all semiconductor refrigeration pieces 8 in a unit volume), or put it another way, on the premise of keeping the total refrigeration capacity sufficient and unchanged, the volume occupied by all semiconductor refrigeration pieces 8 is minimized (the volume occupied by the semiconductor refrigeration pieces 8 is reduced in the unit refrigeration capacity), which is a technical problem that technicians in the field need to solve urgently.

Therefore, the refrigeration mode of the cold surface of the semiconductor refrigeration sheet 8 is changed, a plurality of semiconductor refrigeration sheets 8 can be arranged in the refrigeration device, each metal heat conduction sheet 402 comprises two long and wide surfaces, each long and wide surface of each metal heat conduction sheet 402 is provided with one semiconductor refrigeration sheet 8, namely 2 semiconductor refrigeration sheets 8 are arranged on one metal heat conduction sheet 402, and preferably, the rotating base 4 in the refrigeration device comprises 2-8 metal heat conduction sheets 402, namely, 4-16 semiconductor refrigeration sheets 8 can be arranged at most in the refrigeration device;

in the application, one semiconductor chilling plate 8 rotates around the axial center line of the metal heat conduction pipe 401, so that the semiconductor chilling plate occupies a large volume, 2 semiconductor chilling plates 8 also rotate around the axial center line of the metal heat conduction pipe 401, so that the semiconductor chilling plates occupy a large volume, and the semiconductor chilling plates 8 rotate around the axial center line of the metal heat conduction pipe 401, so that the semiconductor chilling plates occupy a large volume, the volumes occupied by 1 semiconductor chilling plate, 2 semiconductor chilling plates and a plurality of semiconductor chilling plates 8 are not different, and the occupied volume is not increased along with the increase of the number of the semiconductor chilling plates 8;

in the application, as for the number of the finally set semiconductor refrigerating sheets 8 and the refrigerating capacity of each semiconductor refrigerating sheet 8, the number needs to be determined according to the total refrigerating capacity required by the CPU, and the total refrigerating capacity is determined according to the actual needs on site, which is the sum of the refrigerating capacities of all the semiconductor refrigerating sheets 8;

so, this application has solved in crowded limited installation space in practical application, can set up several semiconductor refrigeration pieces 8 more, polylith semiconductor refrigeration piece 8 refrigerates jointly, has improved total refrigerating output (having improved the total refrigerating output of whole semiconductor refrigeration pieces 8 in unit volume promptly), or has traded one to say, keeps under the enough and unchangeable prerequisite of total refrigerating output, has reduced the shared volume of all semiconductor refrigeration pieces 8 (having reduced the shared volume of semiconductor refrigeration piece 8 in unit refrigerating output).

To sum up, in fact, the overall idea of solving the technical problem of the present application is: in the prior art, a method for radiating heat of a CPU by using a semiconductor refrigeration chip 8 is already available, but the prior art has a plurality of technical problems, one of which is as follows: the problem that the semiconductor refrigeration assembly in the prior art has enough refrigeration capacity but too large volume and cannot be put in the semiconductor refrigeration assembly or has enough volume but insufficient refrigeration capacity is caused by the fact that the volume of the semiconductor refrigeration piece 8 is small but the sizes of the matched heat dissipation fins and the heat dissipation fan are too large;

therefore, the heat dissipation mode of the hot surface of the semiconductor refrigeration piece 8 is changed, the heat dissipation fins and the heat dissipation fan are removed, and the refrigeration mode of the cold surface of the semiconductor refrigeration piece 8 is changed on the basis of changing the heat dissipation mode;

thus, the present application solves the problems in the above example as follows: the CPU needs 60W of semiconductor refrigeration sheets 8 for good and sufficient heat dissipation, the requirement is required to be met and cannot be reduced, then 4 semiconductor refrigeration sheets 8 with 15W of refrigeration capacity are selected and 4 semiconductor refrigeration sheets 8 with 15W of refrigeration capacity are respectively arranged on two metal heat conduction sheets 402, 2 semiconductor refrigeration sheets 8 with 15W of refrigeration capacity are arranged on each metal heat conduction sheet 402, the total refrigeration capacity of a refrigeration assembly comprising the 4 semiconductor refrigeration sheets 8 with 15W of refrigeration capacity is enough, the size is small, the refrigeration assembly can be placed into a host case of a computer, the heat dissipation capacity of each semiconductor refrigeration sheet 8 is small (only 15W), the heat dissipation capacity of the hot surface of each semiconductor refrigeration sheet 8 needs about 40W, the heat dissipation capacity of about 40W is small, the hot surface of each semiconductor refrigeration sheet 8 rotates and is in direct contact with air, and the heat dissipation capacity of about 40W can be easily realized, therefore, the technical problems that the refrigerating capacity of the semiconductor refrigerating assembly in the prior art is enough but the volume is overlarge and cannot be put in or the volume can be put in but the refrigerating capacity is not enough are solved.

In this application, this application has changed the radiating mode of the hot side of semiconductor refrigeration piece 8, has torn heat radiation fin and radiator fan down, and whether the heat dissipation capacity of the radiating mode of the hot side of semiconductor refrigeration piece 8 in this application is enough problem, and this application adopts following mode to solve: 1) the rotating speed of the rotating shaft 601 of the direct-current motor is increased, so that the semiconductor chilling plate 8 rotates faster, the heat convection intensity between the hot surface of the semiconductor chilling plate 8 and air is further increased, and the heat dissipation capacity of the hot surface of the semiconductor chilling plate 8 is further increased as the rotating speed of the semiconductor chilling plate 8 is larger, so that the heat dissipation capacity of the hot surface of the semiconductor chilling plate 8 is further increased; 2) in the present application, a maximum of 4-16 semiconductor cooling fins 8 can be provided, the cooling capacity required for good and sufficient heat dissipation of the CPU is constant, the 4-16 semiconductor refrigerating pieces 8 can share the refrigerating capacity, each semiconductor refrigerating piece is divided into a little, therefore, the refrigerating capacity of the cold surface of each semiconductor refrigerating sheet does not need to be too large (between 3 and 20W) after the uniform distribution, and not only does the cold surface of each semiconductor refrigerating sheet need to be too large, therefore, the heat dissipation amount of the hot side of each semiconductor cooling plate does not need to be too large, and if a phenomenon that the heat dissipation amount of the hot side of the semiconductor cooling plate 8 is insufficient occurs, the problem can be solved by adopting a method of further increasing the number of the semiconductor refrigerating pieces so as to further reduce the heat dissipation capacity of each semiconductor refrigerating piece, and the heat dissipation capacity of the smaller heat surface can be easily realized by rotating the heat surface of each semiconductor refrigerating piece 8 and directly contacting with air.

In this application, this application has changed the refrigeration mode of the cold side of semiconductor refrigeration piece 8, and the refrigeration mode about the cold side of semiconductor refrigeration piece 8 in this application whether can cause the problem of dewfall frost condensation, this application adopts following mode to solve: 1) the CPU radiator that this application provided still includes controller and temperature sensor, the controller is equallyd divide do not to be connected with each semiconductor refrigeration piece electricity, the controller with the DC power supply electricity is connected, the controller is connected with temperature sensor electricity, temperature sensor and controller all are located the outside of metal heat pipe, temperature sensor sets up the temperature that the lower length of unable adjustment base's roof is wide on the surface in order to be used for detecting the roof, and when the temperature less than or equal to 15 ℃ that temperature sensor detected, the controller cuts off DC power supply to the power supply of semiconductor refrigeration piece for the semiconductor refrigeration piece cuts off the power supply and stops the refrigeration, takes place the dewfall frost on the CPU in order to avoid the temperature of CPU to hang down; 2) the application can set up 4-16 semiconductor refrigeration pieces 8 at most, but whole semiconductor refrigeration pieces can not be electrified to work simultaneously, the controller can set for the procedure, which semiconductor refrigeration pieces are automatically controlled by the controller to be electrified to work, which semiconductor refrigeration pieces are automatically controlled by the controller to be powered off for rest, all semiconductor refrigeration pieces alternately work or stand by for standby, so that the phenomenon that the service life loss caused by long-time work of the semiconductor refrigeration pieces is too fast can be avoided, the service life of the semiconductor refrigeration pieces is prolonged, the phenomenon that the whole semiconductor refrigeration pieces are electrified to refrigerate simultaneously and the condensation frost is generated on a CPU due to too low concentrated refrigeration temperature can also be avoided.
