However, the fan has the following drawbacks: As the amount of graphics required to accompany the screen increases and becomes more complicated, the aforementioned heat sink has been difficult to maintain the required temperature of the control display. _ The use of a fan as a heat sink does not have the function of dehumidification, so that the electronic zero/amp; I & e-moon in the control display malfunctions due to excessive humidity. Another type of cooling technique for controlling a display of a machine tool uses an electronic thermoelectric wafer as a heat sink, which is based on an application of the ltier effect, that is, when a DC power source passes through the thermoelectric wafer 3 1363855 For the n-type and p-type semiconductor materials, the ceramic surface on both sides of the thermoelectric chip will generate a temperature difference, and the temperature difference is used to remove the heat generated by the machine tool to control the display device. However, the electronic thermoelectric wafer still has the following Missing: 1. The coefficient of performance (coeffiClent 〇f perf〇rrnance, c〇P) of the currently commercially available electronic thermoelectric chips is still too low (c〇p is less than 〇7), and the heat dissipation efficiency is still not good enough. Second, since the electronic thermoelectric chip often needs to remove the heat of the hot end of the thermoelectric chip by a heat sink (for example, an aluminum heat sink), even if a thermal paste is applied between the thermoelectric chip and the heat sink, the two will still There is a considerable degree of contact thermal resistance, which causes the cooling and cooling of the cold end of the electronic thermoelectric chip to become worse, and is even easily burned due to the excessive temperature of the hot end of the thermoelectric chip.

The above and other technical contents, features, and advantages of the present invention will be apparent from the following detailed description of the preferred embodiments. Referring to FIG. 1 , FIG. 2 and FIG. 3 , a preferred embodiment of the micro DC air conditioner cooler of the present invention is used for a control display (not shown) of a machine tool to enter the cold section, and includes a housing. Unit 3... a refrigerant circulation system 4 and a control system 5. The swallowing unit 3 includes a load shell η opposite to a heat sink 32, two upright and opposite side walls 33, and a screen 34 having a load shell formed in the load shell 31. The surface extends to an outer surface - a load air outlet 311 and a load air inlet 312. The heat dissipation shell 32 has a heat dissipation air inlet 21 and a heat dissipation air outlet 322 formed on the inner surface of the heat dissipation shell 32 and extending to the outer surface. The load air outlet 311 is located above the load air inlet 312. The heat dissipation air outlet 322 is located above the heat dissipation air inlet, and the filter screen 34 is disposed at the heat dissipation air inlet 321 . Each of the side walls 33 is connected to the load housing 31 and the heat dissipation housing 32. The inner wall of the side wall 33: the inner surface of the load housing 31 and the inner surface of the heat dissipation housing 32 define a cavity 35. . The refrigerant circulation system 4 is disposed in the chamber 35 and includes a _ straight" evaporation/ring fan 41, a direct flow condensing circulation fan & a refrigerant (a swarf, a sash 43, a plurality of connecting tubes 44 , a micro DC compressor 45 1363855 a condenser 46, a filter 47, an expander 48 and an evaporator 49. The connecting officers 44 sequentially the micro DC compressor 45' condenser 46, the benefits 47. The expander 48, the evaporator 49 and the micro DC compressor 45 are connected in series 'and the refrigerant will circulate in sequence. The micro DC compressor 45 has a brushless design' and can increase the pressure of the gaseous refrigerant. The condenser 46 condenses the gaseous refrigerant into a liquid state through the DC condensing circulation fan 42, which absorbs moisture and filters the refrigerant impurities. The expander 48 is formed of a copper capillary and utilizes a friction effect. Reducing the pressure of the liquid refrigerant, the liquid refrigerant evaporates into a gaseous refrigerant in the evaporator 49, and then flows into the micro DC compressor 45 to form a refrigerant circulation system 4. The insulating cover 43 is located at the evaporator 49 and the condensation. Between 46, At the same time, the load air outlet 311, the load air inlet 312, the direct current evaporation cycle fan 41 and the evaporator 49 are disposed. The evaporator 49 is adjacent to the load air inlet 312 and is located above the micro DC compressor 45. The control display of the machine tool emits a hot load gas (air), the DC evaporative circulation fan 41 is opposite to the load air outlet 311, and is located above the evaporator 49, and the load gas is taken in from the load. The port 312 is brought into the evaporator 49' and takes out the load air outlet 311, and then flows back to the control display of the machine tool. The outer surface of the evaporator 49 forms an evaporation state, and the bottom surface forms a drain pan 492. The gas contacts the evaporating fin tube 491. When the heat exchange is performed, the temperature and humidity are lowered, and the moisture of the loaded gas is condensed into water and accumulated in the drain pan 492, so that the load gas leaves the load air outlet 311. The temperature and humidity are lower than the temperature and humidity of the load gas when entering the load inlet 312. 7 1363855 The condensation H 46 is adjacent to the heat dissipation air outlet 0 322, and the DC condensation circulation fan 42 is The heat dissipation air outlet 322 is opposite to each other, and is located between the condenser 46 and the heat dissipation air outlet 322, and a heat dissipation gas (air) is brought into the condenser 46 from the heat dissipation air inlet 321 , and then the heat dissipation air outlet is taken out. 322. When the heat dissipating gas contacts the condenser 46, the heat of the refrigerant is taken away to condense the refrigerant into a liquid state. Therefore, the temperature of the heat dissipating gas at the heat dissipating air outlet 322 is higher than the temperature of the heat dissipating air inlet 321 . Referring to FIG. 4, the control system 5 includes a control unit 51, a power supply 52, a driver 53, a sensor 54, and a signal converter 55. The control unit 51 has a temperature setting unit 511 for inputting the required temperature, a comparator 512 electrically connected to the temperature setting unit 511, a controller 513 electrically connecting the comparator 512 and the driver 53, and an electrical connection. The display panel 514 of the controller 513. The power supply 52 is electrically connected to the driver 53 to provide a DC voltage to the driver 53. The sensor 54 is adjacent to the load air inlet 312'. The signal converter 55 is electrically connected to the sensor 54 and the comparator. 512 'and transmits an instantaneous temperature of the sensor 54 to the comparator 512'. The temperature setting unit 511 transmits the required temperature to the comparator 512, and the comparator 512 compares the instantaneous temperature to the required temperature. The difference signal is transmitted to the controller 513. The driver 53 is electrically connected and drives the micro DC compressor 45 according to the signal provided by the logic operation of the controller 513, so that the micro DC compressor 45 operates at an appropriate speed. The purpose of precise temperature control. For example, the user can input 35 from the temperature setting unit 511. (: as the preset temperature 'When the instantaneous temperature sensed by the sensor 54 is 35.5 ° C, the 8 1363855 control thief 513 controls the driver 53, which causes the micro DC compressor 45 to Running at normal speed, and achieving a general cooling effect. When the instantaneous temperature sensed by the sensor 54 is published (the difference signal becomes larger), the control benefit 513 controls the driver 53, and the driver brother increases The rotation speed of the micro DC compressor 45 is used to increase the cooling and cooling effect of the micro DC air conditioner cooler. In summary, the micro DC air conditioner cooler of the present invention has the following effects: 1. The volume of the micro DC compressor 45 is equivalent. The tiny (about 36〇cm3)' enables the refrigerant circulation system 4 to be miniaturized, and the overall shape can be densified, making the micro DC air conditioner cooler suitable for installation in the control display of the machine tool, or other small space. The cooling gas is cooled by means of a refrigerant circulation, so that the cooling ability is better than that of a conventional fan or an electronic thermoelectric wafer. When the load gas is cooled, it also has the effect of dehumidification. The load gas is dry when it is conventionally fan-cooled. Therefore, it is possible to prevent the electronic components in the display of the machine tool from malfunctioning due to excessive humidity. The coefficient of performance of the DC air conditioner cooler (C〇p is greater than 2 〇) 'is significantly better than the conventional electronic thermoelectric chip radiator (COP is less than 〇8), so the cooling efficiency is good. 4. The micro DC air conditioner cooler does not occur. When the wafer is overheated and burned, the cooling and heat dissipation process is safe and stable, and has high reliability. 5. The motor efficiency of the micro DC compressor 45 is much higher than the conventional AC voltage 9 1363855 (10%~15%). The utility model has a relatively positive significance for energy saving and carbon reduction. 6. The sensor 54 of the micro DC air conditioner cooler can instantly measure the cross temperature of the load inlet and outlet 312 and the preset required temperature of the temperature setting portion. After comparison, according to the compared difference signal, the rotation speed of the micro-cylinder DC compressor 45 is controlled to achieve precise control of the temperature. It is worth mentioning that The control unit 51 of the above embodiment is a single output mode, and FIG. 5 shows the manner in which the control unit 51 is changed to multiple outputs. The controller 513 is electrically connected to the direct current evaporation circulation fan 41 and the direct current condensation circulation fan 42. And controlling the speed of the DC-type evaporation circulation fan 42 by the DC-evaporation cycle shoulder 41, whereby the DC-type evaporation can be improved if the micro-DC compressor 45 has reached the maximum output capacity (maximum rotation speed) The rotation speed of the circulating fan 41 #DC condensing circulation fan 42 is increased to increase the air volume, and the cooling and cooling capability of the micro DC air conditioner chiller to the control display of the machine tool is further increased.
