Description

Technical Field

[0001] The invention discloses a snowmaking refrigeration device, which belongs to the field of refrigeration technology and relates to snowmaking, ice and snow making equipment, and specifically relates to a snowmaking refrigeration device designed by using semiconductor refrigeration technology. Background Art

[0002] The technical solutions adopted by the currently disclosed artificial snowmaking equipment can be roughly divided into the following two categories. 1) Low-temperature cold air snowmaking - snowmaking equipment uses high-pressure air to mix water flow and beat it into fine mist particles of ice, which are sprayed into the air under the action of wind. The mist particles condense into snowflakes when they encounter the low-temperature cold air outdoors and fall down. 2) Normal temperature snowmaking - snowmaking equipment is equipped with key components such as compressors, condensers and evaporators. With the help of the physical state change of the refrigerant, the heat around the evaporator in the snowmaking chamber of the equipment is absorbed into the condenser and then discharged. The water in contact with the evaporator condenses into an ice layer on the surface of the evaporator after being cooled, and then the ice layer is cut by a scraper to form ice chips that fall into snow.

[0003] Chinese patent announcement number CN108534418B discloses an invention patent named "Snow Drifting Machine" which adopts the above-mentioned normal temperature snowmaking technology solution. It includes a main frame, an ice-making roller, a driving mechanism, a water tank, a scraper and a fan. The ice-making roller includes a rotatable shell arranged on the main frame, and a liquid supply shaft tube penetrating the central axis of the shell. A spiral blade extending from left to right and fixed to the shell is also arranged between the shell and the liquid supply shaft tube. Ethylene glycol solution is passed into the shell of the ice-making roller as a coolant and heat-exchanges with water on the surface of the shell. The water attached to the surface of the shell is condensed into an ice coating on the surface of the shell of the ice-making roller through heat exchange, and then the ice coating is cut by the scraper to form falling snowflakes.

[0004] In actual use, the technical solutions adopted by the above two publicly available artificial snowmaking devices often have various disadvantages and cannot meet various usage scenarios.

[0005] Low-temperature cold air snowmaking can only be accomplished when the weather meets the requirements of extremely cold weather. When the weather is at normal temperature, it is not possible to obtain ice and snow by spraying water mist into the air. Moreover, the snowflakes made by this technical solution are granular, rather than the hollow flakes of natural snowflakes. The granular snow layer is rolled into a hard ice surface structure, which cannot meet the requirements of sports with high requirements for the softness and smoothness of the snow track.

[0006] For normal temperature snowmaking, take the technical solution disclosed in the invention patent with the publication number CN108534418B and the name of "Snowfall Machine" as an example, which uses ethylene glycol solution as the coolant for refrigeration. 1) In the disclosed normal temperature snowmaking technical solutions, no matter what type of refrigerant, it has a low vaporization temperature. Therefore, in a high temperature environment, the refrigerant cooling system may not be able to meet the sufficient snowmaking needs. Furthermore, the maintenance cost of the refrigerant refrigeration system is relatively high. During long-term use, the maintenance of the refrigerant refrigeration system is more cumbersome and requires higher technical requirements. The core components of the equipment are prone to corrosion and need to be replaced and maintained regularly, which increases the cost of use and maintenance pressure. The refrigerant refrigeration system has a slow cooling speed, so the accuracy of temperature control is low. In some occasions with high temperature requirements, the refrigerant refrigeration system may not be able to meet the precise temperature control requirements. 2) Water condenses into an ice layer on the outer surface of the ice-making roller through heat exchange, and then the ice layer is cut by a scraper to form falling snowflakes. To ensure the integrity of the outer surface of the ice-making roller, a certain gap will be retained between the scraper blade and the outer surface of the ice-making roller. Each time the scraper cuts the ice layer, a certain thickness of ice layer will remain on the outer surface of the ice-making roller. The residual ice layer will affect the conduction and radiation of the cold energy generated by the evaporator in the ice-making roller to the outer surface of the ice-making roller.

[0080] Optionally, in the snowmaking refrigeration device of the present invention, an impeller is arranged between the pressure relief port of the pressurizing chamber and the ice and snow cold source outlet. A portion of the impeller passes through the ice and snow cold source outlet and is arranged deep in the refrigeration chamber, and another portion thereof is arranged toward the pressure relief port of the pressurizing chamber, and the impeller can rotate under the blowing of the gas in the pressurizing chamber.

[0081] The beneficial effects of the present invention are:

[0082] 1. The snowmaking refrigeration equipment provided by the present invention effectively utilizes the large temperature difference between the hot and cold surfaces of semiconductor refrigeration technology, and with auxiliary cooling technologies such as vortex coolers, it can make the temperature difference between the refrigeration chamber and the heating chamber more than 65°C. When the heating chamber adopts strong heat dissipation, the temperature of the refrigeration chamber can reach an extremely cold condition of minus 50 degrees Celsius, making it have the function of splashing water into ice and spraying into snow.

[0083] 2. The snowmaking refrigeration equipment provided by the present invention can directly condense water from a gas-liquid mixed state into a solid state through a refrigeration chamber, so that ice particles and snow haze grow into snowflakes or flaky ice crystals in the refrigeration chamber and are then blown out of the refrigeration chamber.

[0084] 3. Semiconductor refrigeration technology occupies less space in the body, making the equipment light and portable. Under the conditions of external power supply and water pipes, it can move with the water source to get water nearby, or it can draw cold water that has been pre-cooled to the freezing point but not condensed into the equipment to further increase the snow and ice making speed of the equipment.

[0085] 4. Snowmaking refrigeration equipment uses conductor refrigeration technology for cooling. When necessary, refrigerant can be added to improve the efficiency of snowmaking and ice making. When the refrigerant is only used as an auxiliary refrigeration material, its use cost is relatively low and it is less corrosive to the core components of the equipment.

[0086] 5. The snow-making refrigeration equipment provided by the present invention adopts a vibration function de-icing method generated by an agitation device. The ice coating on the cooling body in the refrigeration chamber will fall off completely with the vibration force. Compared with the traditional scraper cutting of the ice coating, it will neither affect the cold energy conduction of the semiconductor refrigeration plate to the cooling body nor cause damage to the outer surface of the cooling body.

[0087] 6. The present invention provides a snowmaking refrigeration device having a normal mobile mode and a flying motion mode. Compared with those snowmaking devices fixed on a wall or a trailer, the normal mobile mode has a portable and free-to-move function. The flying motion mode can more realistically restore the atmosphere of the snowfall in the air, that is, the snow falling from above and following you like a shadow.

[0088] The beneficial effects of the present invention are not limited to this description. For better understanding, a more detailed description is given in the specific implementation section. BRIEF DESCRIPTION OF THE DRAWINGS

[0126] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations.

[0127] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0128] The snowmaking refrigeration equipment described in the present invention mainly includes a body, a semiconductor refrigeration sheet, a heat sink, a cold concentrator, a heat dissipation fan, an agitation device, a main control circuit board, a power supply component and a fluid supply device.

[0129] The semiconductor refrigerator is a cooling device composed of semiconductors. In principle, the semiconductor refrigerator is a single heat transfer tool. When current passes through a thermocouple pair formed by a piece of N-type semiconductor material and a piece of P-type semiconductor material, heat transfer will occur between the two ends. The heat will be transferred from one end to the other, thereby generating a temperature difference to form a hot and cold end.

[0130] The heat sink is used to be attached to and arranged on the heating end of the semiconductor refrigeration plate to conduct and transfer the heat emitted by the semiconductor refrigeration plate during the refrigeration process.

[0131] The cooling body is used to be attached to and arranged at the cooling end of the semiconductor cooling sheet to collect and store the cooling energy generated by the semiconductor cooling sheet, and at the same time radiate the cooling energy into the cooling cavity.

[0132] Agitating device: When the snow-making refrigeration equipment is working, some icicles or ice crystals will be wrapped around the cooling body, which will affect the cooling body's outward radiation of cold energy. The agitating device is used to shake off these icicles or ice crystals on the cooling body.

[0133] The fluid supply device is used to input gas or liquid into the heat dissipation cavity and the refrigeration cavity of the snowmaking refrigeration equipment.

[0134] The overall structure and operation mode of the snowmaking refrigeration equipment described in the present invention include: Figure 1 The normal movement mode shown and Figure 2 The flying motion pattern shown.

[0135] The following further describes the structure of the snowmaking refrigeration equipment in a normal mobile mode in conjunction with the accompanying drawings and specific embodiments of the present invention.

[0136] For details, see Figure 1 Figure 3 Figure 5 Figure 8 Fig.16 As shown;

[0137] Among the main components of the ordinary mobile mode snowmaking refrigeration equipment, the semiconductor refrigeration plate 2, the heat sink 3, the cooling body 4, the cooling fan 5a, the agitation device and the main control circuit board 7 are arranged inside the body 1, and the power supply component and the fluid supply device are arranged inside the body 1 or outside the body 1.

[0138] Inside the snowmaking refrigeration equipment body 1, the heating surface 2a of the semiconductor refrigeration sheet 2 is arranged in abutment with one end surface of the heat sink 3, and the cooling surface 2b of the semiconductor refrigeration sheet 2 is arranged in abutment with one end surface of the cooling body 4. Inside the body 1, the cavity space corresponding to the heating surface 2a of the semiconductor refrigeration sheet 2 is the snowmaking refrigeration equipment heat dissipation cavity 31, and the cavity corresponding to the cooling surface 2b of the semiconductor refrigeration sheet 2 is the snowmaking refrigeration equipment cooling cavity 41.

[0139] The heat dissipation cavity 31 of the snow-making refrigeration equipment is formed by the space between the heat dissipation element 3 and the inner wall of the body 1 adjacent thereto. When the snow-making refrigeration equipment is in refrigeration operation, the heat generated by the heating surface 2a of the semiconductor refrigeration plate 2 is absorbed by the heat dissipation element 3 and the heat is conducted into the heat dissipation cavity 31, and the heat in the heat dissipation cavity 31 is discharged out of the body 1 under the action of the heat dissipation fan 5a. The heat dissipation fan 5a is arranged in the body 1 at the side of the heat dissipation element 3, and the body 1 is provided with an air inlet 1a at a position close to the heat dissipation fan 5a, and the body 1 is provided with an air outlet 1b at the other end of the spacer between the heat dissipation elements. The heat dissipation fan 5a inhales air through the air inlet 1a and blows the heat in the heat dissipation cavity 31 out of the body 1 through the air outlet 1b.

[0140] The refrigeration chamber in the snowmaking refrigeration equipment body described in this embodiment is formed in the following four structural forms.

[0141] Example 1, see Figure 3 Figure 4 As shown;

[0142] The cavity structure of the cooling body 4 in the body 1 of the snow-making refrigeration equipment forms a refrigeration cavity 41 in the body 1, and the semiconductor refrigeration plate 2 and the heat sink 3 are arranged around the cooling body 4, and the cooling surface 2b of the semiconductor refrigeration plate 2 is arranged in contact with the outer wall of the cooling body 4. In this embodiment, the multiple semiconductor refrigeration plates 2 are simultaneously arranged around and attached to all outer wall surfaces of the cooling body 4, and can also be separately arranged around and attached to a single or multiple outer wall surfaces of the cooling body 4.

[0143] In this embodiment, the heat sink 3 forms a plurality of heat dissipation chambers 31 around the space between the heat dissipation element 3 and the inner wall of the body 1, and the heat dissipation chambers 31 are arranged to surround the refrigeration chamber 41. All heat dissipation chambers 31 can be closed or connected. Preferably, a heat dissipation fan 5a is provided on one side of each heat dissipation chamber 31, and an air inlet 1a and an air outlet 1b are provided at both ends of the heat dissipation chamber 31 on the body 1.

[0144] Example 2, see Figure 5 Figure 6 As shown;

[0145] The semiconductor refrigeration sheet 2 is arranged in the middle of the machine body 1, the cooling body 4 and the heat sink 3 are respectively attached to the cooling surface 2b and the heating surface 2a of the semiconductor refrigeration sheet 2, the cooling body 4 and the inner wall of the machine body 1 form a cooling cavity 41, and the heat sink 3 and the inner wall of the machine body 1 form a heat dissipation cavity 31. In this embodiment, the heat dissipation cavity 31 is arranged in the machine body 1 corresponding to the cooling cavity 41.

[0146] Example 3, see Figure 8 Fig. 9 As shown;

[0147] The space formed by the two cooling bodies 4 in the body 1 of the snowmaking refrigeration equipment is a refrigeration cavity 41. The facing end surfaces of the two cooling bodies 4 are respectively in contact with the refrigeration surface 2b of the semiconductor refrigeration plate 2. The heat sink 3 arranged opposite to the two cooling bodies 4 and the space of the inner wall of the body 1 on this side form a heat dissipation cavity 31. In this embodiment, the two heat dissipation cavities 31 are arranged in the body 1 corresponding to the refrigeration cavity 41 above and below or left and right. Preferably, a heat dissipation fan 5a is provided on one side of each heat dissipation cavity 31, and an air inlet 1a and an air outlet 1b are provided at both ends of each heat dissipation cavity 31 on the body 1.

[0148] Example 4, see Fig.16 Fig.17 As shown;

[0149] The snowmaking refrigeration equipment has a body 1 in which two groups of four cooling bodies 4 are relatively spliced ​​and combined to form a refrigeration cavity 41, and a plurality of semiconductor refrigeration plates 2 have cooling surfaces 2b respectively fitted with one surface of the upper and lower and left and right cooling bodies 4, and the heat sink 3 arranged opposite to the four cooling bodies 4 and the space on the inner wall of the body 1 on this side form a heat dissipation cavity 31.

[0150] In this embodiment, four heat dissipation chambers 31 are arranged in the machine body 1 corresponding to the refrigeration chamber 41 in the upper and lower parts and the left and right parts. All heat dissipation chambers 31 can be closed or connected. Preferably, a heat dissipation fan 5a is arranged on one side of each heat dissipation chamber 31, and an air inlet 1a and an air outlet 1b are arranged at both ends of the heat dissipation chamber 31 on the machine body 1.

[0151] For details, see Figure 3 Figure 5 Fig.14 Fig.15 As shown, in the ordinary moving mode of the snowmaking refrigeration equipment of the present invention, the body 1 is located at the end of the refrigeration chamber 41 and is provided with an ice and snow cold source outlet 1c connected to the refrigeration chamber 41.

[0152] Further, such as Figure 3 Fig.14 Fig.15 As shown, the ice and snow cold source outlet 1c is arranged at the end of the body 1 in parallel with the refrigeration cavity 41, and the ice and snow cold source outlet 1c is arranged on the rear end surface of the body 1 and is in a straight-through structure with the refrigeration cavity 41.

[0153] Further, if you read Figure 5 As shown, the ice and snow cold source outlet 1c is arranged at the end of the body 1 in a non-parallel manner to the refrigeration cavity 41, and the ice and snow cold source outlet 1c is arranged on the lower end surface of the body 1 and forms an angle structure with the refrigeration cavity 41.

[0154] In the snow-making refrigeration equipment of the present invention, the fluid output end of the fluid supply device can be arranged toward the refrigeration cavity alone, and the fluid output end of the fluid supply device can also be arranged toward the heat dissipation cavity alone. Preferably, the fluid output end of the fluid supply device of the snow-making refrigeration equipment is arranged toward both the refrigeration cavity and the heat dissipation cavity. The agitation device of the snow-making refrigeration equipment is arranged on one side of the body close to the refrigeration cavity.

[0155] More specifically, the power supply component of the snowmaking refrigeration equipment described in the present invention has the following three specific structures. Figure 1 Figure 3 Figure 6 Figure 8 As shown, the power supply component of the snowmaking refrigeration equipment is an external power supply interface 8a. Figure 4 As shown, the power supply component of the snowmaking refrigeration equipment is an external cable 8b. Figure 8 Fig. 9 Fig.10 As shown, the power supply component of the snowmaking refrigeration device is a battery 8c and a control circuit electrically connected to the main control circuit board 7, and the control circuit 8d is electrically connected to the main control circuit board 7. Preferably, the control circuit is arranged on the main control circuit board 7.

[0156] For more details, see Figure 3 Figure 4 Figure 5 Figure 6 Figure 8 Fig. 9 As shown, the main control circuit board 7 is electrically connected to the external power interface 8a and external cable 8b of the power supply component, the semiconductor cooling sheet 2, the cooling fan 5a, and the excitation device.

[0157] The following further describes the snow-making and ice-making method of a snow-making and refrigeration device in a common mobile mode according to the present invention in conjunction with the accompanying drawings and specific embodiments.

[0158] See also Figure 3 Figure 5 Figure 8 As shown, the semiconductor refrigeration sheet 2 is powered on by the power supply assembly 8 under the control of the main control circuit board 7 to enter the cooling mode. While the cooling surface 2b of the semiconductor refrigeration sheet 2 is cooling, the heat generated by the heating surface 2a of the semiconductor refrigeration sheet 2 is introduced into the heat dissipation cavity 31 by the heat dissipation element 3 and then blown out of the heat dissipation cavity 31 by the heat dissipation fan 5a through the air outlet 1b. As the cooling power of the cooling surface 2b of the semiconductor refrigeration sheet 2 is continuously increased, when the heat generated by the heating surface 2a of the semiconductor refrigeration sheet 2 cannot be effectively and quickly dissipated through the heat dissipation cavity 31, the fluid supply device is powered on by the power supply assembly under the control of the main control circuit board 7 and forcefully sprays gas or liquid onto the heat dissipation element 3 of the heat dissipation cavity 31, so that the heat generated by the heating surface 2a of the semiconductor refrigeration sheet 2 that is gathered and absorbed on the heat dissipation element 3 is quickly dissipated from the heat dissipation cavity 31 to the outside of the machine body 1.

[0159] See also Figure 3 Figure 5 Figure 8 As shown, the cold energy generated by the cooling surface 2b of the semiconductor refrigeration plate 2 is gathered in the refrigeration cavity 41 under the conduction of the cold gathering body 4, and the fluid supply device sprays water mist into the refrigeration cavity 41 after the power supply component is powered on under the control of the main control circuit board 7. The water mist enters the refrigeration cavity 41 and quickly crystallizes when it is cooled, and the crystalline ice crystals or snowflakes are discharged outward through the ice and snow cold source outlet 1c at the end of the body 1. When the condensed ice crystals covering the cold gathering body 4 in the refrigeration cavity 41 affect the outward conduction of the cold energy generated by the cooling surface 2b of the semiconductor refrigeration plate 2, the agitation device emits ultrasonic waves or vibration waves to the cold gathering body 4 under the control of the main control circuit board 7 after the power supply component is powered on, and the ice crystals condensed on the cold gathering body 4 quickly fall off under the action of the ultrasonic waves or vibration waves, and the ice chips after falling off will be transformed into snowflakes under the action of airflow and inertial force and blown out through the ice and snow cold source outlet 1c at the end of the body 1 to the outside of the body 1.

[0160] The flying motion mode body structure of a snowmaking refrigeration device of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0161] The flying motion mode snowmaking refrigeration equipment is suitable for aerial snowmaking scenes, such as Figure 1 Fig. 22 Fig.23 Fig.24 Fig.25 As shown, the snowmaking refrigeration equipment in the flight motion mode includes a body 1, a semiconductor refrigeration plate 2, a cooling body 4 and a main control circuit board 7 arranged in the body 1, an agitation device, a power supply component and a fluid supply device arranged in or outside the body 1, and a heat sink 3 and a propeller fan 5b arranged outside the body 1.

[0162] Inside the snowmaking refrigeration equipment body 1, the heating surface 2a of the semiconductor refrigeration sheet 2 is arranged in contact with the portion where the inner end surface of the heat sink 3 extends into the body, the heat sink 3 and the outer wall of the body 1 form a heat dissipation surface 32, and the cooling surface 2b of the semiconductor refrigeration sheet 2 is arranged in contact with the cooling body 4. Inside the body 1, the cavity space formed by the cooling body 4 corresponding to the cooling surface 2b of the semiconductor refrigeration sheet 2 is the refrigeration cavity 41 of the snowmaking refrigeration equipment.

[0163] On the outside of the snowmaking refrigeration equipment body 1, the propeller fans 5b are arranged above the heat sink 3 and are symmetrically arranged in two or more groups around the body 1. In this example, the propeller fans 5b are two groups of four symmetrically arranged around the body 1. The propeller fans 5b suck in the air at their upper ends and blow it downward. A small part of the air blown downward by the propeller fans 5b is used for rapid heat dissipation of the heat sink 3 when it blows through the heat dissipation surface 32. The vast majority of the air blown downward by the propeller fans 5b pushes the snowmaking refrigeration equipment to move upward and rise.

[0164] In the flying motion mode embodiment of the snowmaking refrigeration equipment of the present invention, the formation structure and arrangement of the refrigeration chamber in the body of the equipment include the following three structural forms.

[0165] Example 1, see Fig. 22 As shown;

In this embodiment, the plurality of semiconductor refrigeration sheets 2 are arranged around and attached to all outer wall surfaces of the cooling body 4 at the same time, and can also be arranged around and attached to a single or multiple outer wall surfaces of the cooling body 4. In this embodiment, the heat sink 3 forms a plurality of heat dissipation surfaces 32 around the outer wall of the body 1, and the heat dissipation surfaces 32 are arranged to surround the refrigeration cavity 41.

[0167] Example 2, see Fig.23 Fig.24 As shown;

[0168] The space in which two cooling bodies 4 are relatively spliced ​​and arranged in the body 1 of the snowmaking refrigeration device forms a refrigeration cavity 41, and the facing end surfaces of the two cooling bodies 4 are respectively in contact with the refrigeration surface 2b of the semiconductor refrigeration plate 2, and the heat sink 3 arranged relatively to the two cooling bodies 4 forms a heat dissipation surface 32 with the outer wall of the body 1 on this side. In this embodiment, the two heat dissipation surfaces 32 are arranged outside the body 1 corresponding to the front and back or left and right of the refrigeration cavity 41.

[0169] Example 3, see Fig.25 As shown;

[0170] The snowmaking refrigeration equipment has two groups of four cooling bodies 4 in its body 1 that are relatively spliced ​​and arranged in a combined space to form a refrigeration cavity 41, and a plurality of semiconductor refrigeration plates 2 have their cooling surfaces 2b respectively fitted with one surface of the upper and lower and left and right cooling bodies 4, and the heat sink 3 arranged opposite to the four cooling bodies 4 forms a heat dissipation surface 32 with the outer wall of the body 1 on this side.

[0171] In this embodiment, four heat dissipation surfaces 32 are arranged outside the body 1 corresponding to the front and back and left and right of the refrigeration cavity 41 .

[0172] More specific Fig. 22 Fig.24 As shown, the snowmaking refrigeration equipment of the present invention has a body 1 at the end of the refrigeration chamber 41, which is provided with an ice and snow cold source outlet 1c connected to the refrigeration chamber 41. Fig. 22 Fig.24As shown, the ice and snow cold source outlet 1c is arranged at the end of the body 1 in parallel with the refrigeration cavity 41, and the ice and snow cold source outlet 1c is arranged on the rear end surface of the body 1 and is in a straight-through structure with the refrigeration cavity 41.

[0173] More specifically, the fluid output end of the fluid supply device of the flying motion mode snowmaking refrigeration equipment of the present invention is arranged toward the refrigeration cavity. The agitation device of the snowmaking refrigeration equipment is arranged on the body near the refrigeration cavity.

[0174] More specifically, referring to the snowmaking refrigeration equipment of the present invention, in its normal moving mode Figure 1 Figure 3 Figure 6 Figure 8 As shown, the power supply component of the flying motion mode snowmaking refrigeration equipment described in this embodiment has the following three specific structures: the power supply component of the snowmaking refrigeration equipment is an external power supply interface 8a or the power supply component 8 of the snowmaking refrigeration equipment is an external cable 8b. Figure 1 As shown, the power supply component 8 of the snowmaking refrigeration device is a battery 8c and a control circuit thereof, and the control circuit is electrically connected to the main control circuit board 7. Preferably, the control circuit is arranged on the main control circuit board 7.

[0175] For more details, see Figure 1 Fig. 22 Fig.23 Fig.24 Fig.25 As shown, the main control circuit board 7 is electrically connected to the external power interface and external cable of the power supply component, the semiconductor cooling sheet 2, the propeller fan 5b, and the agitation device.

[0176] The flying motion mode snow-making and ice-making method of the snow-making refrigeration equipment described in this example has the same principles, processes and methods as the ordinary moving mode snow-making and ice-making, and this embodiment will not be repeated here.

[0177] In order to ensure the lifting and movement stability of the flying motion mode snowmaking refrigeration equipment in the present invention in the aerial flying snowmaking scene, the snowmaking refrigeration equipment also includes a flight control module, a sensor module and a communication module electrically connected to the main control circuit board.

[0178] The flight control module is used to adjust the attitude of the snow-making refrigeration equipment when it is taking off. It can obtain the status information of the snow-making refrigeration equipment through sensors, such as attitude, acceleration, angular velocity, etc., and then perform corresponding flight control according to the instructions of the remote control.

[0179] The sensor module obtains the position, altitude, environment, and obstacle information of the snowmaking equipment when it is in flight. It senses the surrounding environment and transmits the data to the flight control system. The sensor module includes flight control, navigation, communication, image processing, and other aspects.

[0180] The communication module sends out command signals through the remote control or mobile terminal, and the radio waves are transmitted to the receiver, and then to the flight control module, which performs attitude adjustment, direction control, speed control, etc. The flight control module is also responsible for receiving and sending sensor data, telemetry data, etc., and at the same time obtains various information recorded by the flight control module and sensor module of the snowmaking equipment and performs data exchange and signal control on the snowmaking equipment in real time.

[0181] In order to enhance the snow-making and ice-making effect of the snow-making refrigeration device described in the present invention and further reduce the temperature in the refrigeration chamber, in the normal moving mode and the flying motion mode of the snow-making refrigeration device, multiple semiconductor refrigeration plates can be arranged in multiple groups on the body.

[0182] Specific as Fig. 22 As shown, any outer wall surface of the cooling body 4 with a cavity structure in the body 1 is provided with two or more groups of semiconductor cooling sheets 2. The cooling body 4 is in contact with the cooling surfaces 2b of the two or more groups of cooling sheets 2, and the heating surfaces 2a of each group of cooling sheets 2 are in contact with the heat sink 32 respectively.

[0183] like Fig.23 Fig.24 As shown, any outer wall surface of the cooling body 4 spliced ​​and assembled to form the cooling chamber is provided with two or more groups of semiconductor cooling sheets 2. The cooling body 4 is in contact with the cooling surfaces 2b of the two or more groups of cooling sheets 2, and the heating surfaces 2a of each group of cooling sheets 2 are in contact with the heat sink 32 respectively.

[0184] like Fig.23 As shown, any outer wall surface of the cooling body 4 of two groups of four relatively spliced ​​and arranged to form a cooling chamber 41 is provided with two or more groups of semiconductor cooling sheets 2. The cooling body 4 is in contact with the cooling surfaces 2b of the two or more groups of cooling sheets 2, and the heating surface 2a of each group of cooling sheets 2 is in contact with the heat sink 32 respectively.

[0185] Further, such as Fig. 22 Fig.23 Fig.24 Fig.25 In the above three structures in which the cooling body 4 forms a cooling cavity 41, the heat sink 3 which is in contact with the heating surface 2a of the semiconductor cooling plate 2 is in contact with the heating surface 2a of all the semiconductor cooling plates 2 at the same time, and the heat sink cavities 31 corresponding to the heating surface 2a of each group of semiconductor cooling plates 2 are interconnected.

[0186] In the normal moving mode and the flying moving mode of the above-mentioned snow-making refrigeration equipment of the present invention, the ice crystals or snowflakes formed in the refrigeration cavity are naturally discharged outwardly from the machine body through the ice and snow cold source outlet. In order to prevent the ice crystals or snowflakes from being accumulated in the refrigeration cavity due to failure to be removed in time, thereby affecting the snow-making and ice-making effect of the snow-making refrigeration equipment, the snow-making refrigeration equipment of the present invention is also provided with a first external forced discharge mode for the ice crystals or snowflakes through the ice and snow cold source outlet.

[0187] Specifically, Figure 4 The normal movement mode of the snowmaking and refrigeration equipment shown Fig.23 In the flying motion mode of the snowmaking refrigeration equipment shown, a booster fan 5c is provided on the body 1 at the front end of the refrigeration cavity 41 and away from the ice and snow cold source outlet 1c, and the booster fan 5c is electrically connected to the main control circuit board 7. Figure 3 Fig.23 As shown, the machine body 1 is provided with an air inlet II1d at the front end of the boost fan 5c.

[0188] Specifically, Fig.17 The normal movement mode of the snowmaking and refrigeration equipment shown Fig.25 In the flight motion mode of the snowmaking refrigeration equipment shown, a solid-state piezoelectric fan 5d is provided on the body 1 at a position located at the front end of the refrigeration chamber 41 and away from the ice and snow cold source outlet 1c. The solid-state piezoelectric fan 5d is electrically connected to the main control circuit board 7. The solid-state piezoelectric fan 5d is composed of a piezoelectric ceramic sheet 5d1 and a flexible diaphragm 5d2. The flexible diaphragm 5d2 is partially located in the refrigeration chamber 41. Figure 3 Fig.23 As shown, the body 1 is provided with an air inlet II1d at the front end of the solid-state piezoelectric fan 5d. The inverse piezoelectric effect of the piezoelectric ceramic sheet 5d1 forces the piezoelectric ceramic to expand and contract periodically, and drives the flexible diaphragm 5d2 to vibrate at the same frequency to generate bending resonance, thereby stimulating the surrounding fluid to form a high-speed and stable air jet that flows forward from the tip of the flexible diaphragm 5d2.

[0189] refer to Figure 4 Fig.17 Fig.23 Fig.25 As shown, when the ice crystals or snowflakes in the refrigeration chamber 41 cannot be discharged smoothly through the ice and snow cold source outlet 1c under natural conditions and accumulate in the refrigeration chamber 41, the boost fan 5c or the pressure electric fan 5d is energized by the power supply component under the control of the main control circuit board 7 to blow strong air into the refrigeration chamber 41. At the same time, with the cooperation of the agitation device in the body 1, the ice crystals or snowflakes are quickly discharged out of the body 1 through the ice and snow cold source outlet 1c along with the strong wind in the refrigeration chamber 41.

[0191] refer to Figure 2 Figure 5 Fig.14 Fig.16 As shown, the setting of the boost nozzle 5e makes the diameter of the ice and snow cold source outlet 1c of the body 1 smaller, and at the same time slows down the speed at which ice crystals or snowflakes in the refrigeration chamber 41 are discharged outward. When the boost fan 5c or the pressure electric fan 5d blows air into the refrigeration chamber 41 and the pressure in the refrigeration chamber 41 gradually increases, the ice crystals or snowflakes discharged outward through the boost nozzle 5e are sprayed farther, making the snowmaking refrigeration equipment described in the present invention more suitable for some special usage scenarios.

[0192] As optional Fig.14 As shown, the boost nozzle 5e and the ice and snow cold source outlet 1c of the body 1 are matched with each other and are provided with a magnetic connection structure composed of S pole and N pole magnetic connection points.

When the fluid supply device sprays fluid into the refrigeration cavity, its main function is to provide a water source for the refrigeration cavity to make snow and ice, and at the same time, it can further reduce the temperature in the refrigeration cavity. When the fluid supply device sprays fluid into the heat dissipation cavity, it helps to speed up the cooling and heat dissipation speed of the heat dissipation cavity, thereby improving the refrigeration efficiency of the semiconductor refrigeration plate. The power for the fluid spray in the fluid supply device comes from an external pressure gas source or water source, a water pump and an air pump arranged in the body.

[0254] Embodiment 10, microporous atomization water permeability mode;

[0255] In the normal moving mode and the flying moving mode of the snow-making refrigeration equipment, this embodiment is explained by taking the snow-making refrigeration equipment in which two cooling bodies are spliced ​​and combined to form a refrigeration cavity as an example, and the fluid supply device acts on the heat dissipation cavity or the refrigeration cavity alone.

[0256] refer to Figure 6 Figure 7 Fig. 20 Fig.21 As shown, the fluid supply device includes an ultrasonic microporous atomizing sheet 9L and an atomizing circuit. Fig. 20 Fig.21As shown, the ultrasonic microporous atomizing sheet 9L is arranged through the cavity wall adjacent to the water source device A and the heat dissipation cavity 31, and the atomizing circuit is electrically connected to the main control circuit board 7. The water permeable surface 9L1 of the ultrasonic microporous atomizing sheet 9L faces the water source device A, and the atomizing surface 9L2 of the ultrasonic microporous atomizing sheet 9L faces the heat dissipation cavity 31. A plurality of micropores 9L3 are arranged on the water permeable surface 9L1, and the micropores 9L3 are arranged through the entire ultrasonic microporous atomizing sheet 9L.

[0257] like Fig. 20 Fig.21 As shown, when the liquid of the water source device A contacts the micropores 9L3 on the ultrasonic microporous atomizing sheet 9L, the liquid molecules of the water source device A will penetrate into the atomizing surface 9L2 of the ultrasonic microporous atomizing sheet 9L through the micropores 9L3 of the water permeable surface 9L1 under the action of gravity. The ultrasonic microporous atomizing sheet 9L generates high-frequency vibrations through a high-frequency power supply, and the high-frequency vibrations cause the liquid that penetrates the micropores 9L3 of the water permeable surface 9L1 to generate tiny particle water mist and spray it into the heat dissipation cavity 31.

[0258] refer to Fig.10 Fig.11 Fig. 20 Fig.21 As shown, the fluid supply device includes an ultrasonic microporous atomizing sheet 9L penetrating the bottom of the bottle cap structure 9q and an atomizing circuit electrically connected to the main control circuit board 7. The ultrasonic microporous atomizing sheet 9L has its water permeable surface 9L1 facing the water storage bottle 9r, and its atomizing surface 9L2 facing the heat dissipation cavity 31 ( Fig.11 As shown), or its atomizing surface 9L2 is arranged toward the refrigeration cavity 41 ( Fig.25 As shown), a plurality of micropores 9L3 are provided on the water permeable surface 9L1, and the micropores 9L3 run through the entire ultrasonic microporous atomizing sheet 9L.

[0259] like Fig.11 As shown, when the liquid in the water storage bottle 9r contacts the micropores 9L3 on the ultrasonic microporous atomizing sheet 9L, the liquid molecules in the water storage bottle 9r will penetrate into the atomizing surface 9L2 of the ultrasonic microporous atomizing sheet 9L through the micropores 9L3 of the water permeable surface 9L1 under the action of gravity. The ultrasonic microporous atomizing sheet 9L generates high-frequency vibrations through a high-frequency power supply, and the high-frequency vibrations cause the liquid that penetrates the micropores 9L3 of the water permeable surface 9L1 to generate tiny particle water mist and spray it into the heat dissipation cavity 31.

[0260] In the ordinary moving mode and the flying moving mode of the snow-making refrigeration equipment mentioned above of the present invention, the agitation device acts in the refrigeration cavity to shake off the icicles or ice crystals covering the refrigeration body, and the specific component structure and setting mode have the following implementation modes.

[0261] Embodiment 1,

[0262] See also Fig.15As shown, this embodiment is described by taking a snowmaking refrigeration device in which two cooling bodies are spliced ​​and arranged to form a refrigeration chamber as an example, and the excitation device of the snowmaking refrigeration device is an electromagnetic pulse generator. The electromagnetic pulse generator includes a pulse control circuit, a high-voltage capacitor 6a, and a pulse coil 6b. The pulse coil 6b is installed on the cooling body 4 or fits with the cooling body 4, and the pulse control circuit is electrically connected to the capacitor 6a and the main control circuit board 7 respectively.

[0263] In this embodiment, see Fig.15 As shown, a columnar body 6c is provided at one end of the electromagnetic pulse generator that penetrates into the refrigeration cavity 41, and a pulse coil 6b is wound on the columnar body 6c of the electromagnetic pulse generator, and the outer ring surface of the pulse coil 6b is in contact with the cooling body 4. After the high-voltage capacitor 6a is powered by the power supply component under the control of the main control circuit board 7, the pulse control circuit drives the high-voltage capacitor 6a to discharge instantly to the pulse coil 6b, and an electromagnetic eddy current field is quickly formed and decayed around the pulse coil 6b that receives the high-voltage current and on the cooling body 4, thereby generating a transient electromagnetic force in the refrigeration cavity 41. After the eddy current appears on the surface of the cooling body 4, the electromagnetic force further generates a pulse force similar to a "hammer" vibration. The vibration pulse causes the surface of the cooling body 4 to vibrate rapidly and causes the ice crystals condensed on the surface of the cooling body to deform and break or fall off. The ice chips that fall off will become snowflakes under the action of airflow and inertia force and be blown out of the body 1 through the ice and snow cold source outlet 1c at the end of the body 1.

[0266] In this embodiment, see Figure 3 Fig.14As shown, the acoustic transducer 6d is arranged at the end of the refrigeration chamber 41 in the body 1, and its ultrasonic probe 6e is close to or close to the cooling body 4. After the acoustic transducer 6d is powered by the power supply assembly under the control of the main control circuit board 7, the acoustic transducer 6d receives the electric oscillation signal sent by the acoustic wave control circuit, which will cause the change of the electric field or magnetic field in the electric energy storage element in the acoustic transducer 6d. The effect of this change produces a single driving force on the mechanical vibration system of the acoustic transducer 6d, so that it enters a vibration state, thereby promoting the cooling body 4 adjacent to or in contact with the ultrasonic probe 6e of the mechanical vibration system of the acoustic transducer 6d to resonate at the same frequency, and the vibration pulse causes the surface of the cooling body 4 to vibrate rapidly and causes the ice crystals condensed on the surface of the cooling body to deform and break or fall off. The ice chips after falling off will become snowflakes under the action of airflow and inertial force and blown out through the ice and snow cold source outlet 1c at the end of the body 1 to be discharged outside the body 1.

[0276] Embodiment 5,

[0277] See also Fig.13 As shown, the agitation device described in this embodiment is explained by taking a snowmaking refrigeration device in which two cooling bodies are spliced ​​and combined to form a refrigeration chamber as an example. The agitation device is a vibration generating device, and the vibration generating device is a vibration generator composed of a motor 6f, an eccentric wheel 6g, an eccentric wheel hammer 6g and a hammer head 6z. The motor 6f is electrically connected to the main control circuit board 7, the eccentric wheel 6g is connected to the rotor of the motor 6f, and the hammer head 6z is flexibly connected to the eccentric wheel hammer 6g through a spring. The motor 6f drives the eccentric wheel hammer 6g to rotate and drives the hammer head 6z to intermittently touch the snow body 4b / 4c / 4d / 4e (drawn in the figure), or the cooling body 4, or the collision body 6h.

[0278] In the above-mentioned vibration generating device embodiment, refer to Fig.13 and Fig.17 As shown, the motor 6f rotates after being powered by the power supply component under the control of the main control circuit board 7, and the eccentric hammer wheel 6g rotates under the drive of the motor 6f.

The fallen ice chips will become snowflakes under the action of airflow and inertia and be blown out of the body 1 through the ice and snow cold source outlet 1c at the end of the body 1.

[0280] Optionally, the heat sink is a heat sink made of metal.

[0281] Optionally, the heat sink is a graphite sheet heat sink structure or a heat sink structure made of graphene material.

[0282] Optionally, the heat sink is a heat sink structure made of CNT nanotube material.

[0283] As an option, Fig.16 As shown, this embodiment is described by taking a snowmaking refrigeration device in which four cooling bodies are spliced ​​and arranged to form a refrigeration chamber as an example, and the heat dissipation end surface of the heat dissipation element 3 is connected to a condenser 3a.

[0284] In the ordinary moving mode and the flying moving mode of the snowmaking refrigeration equipment of the present invention, the cooling body is made of a material that is a good conductor of heat.

[0285] Optionally, the cooling body is a thermal conductive structure made of metal material. Optionally, the cooling body is a thermal conductive structure made of graphite sheet or graphene material. Optionally, the cooling body is a thermal conductive structure made of CNT nanotube material.

[0286] Further preferably, the cooling body is a temperature-conducting structural member made of a composite of two or more materials including metal, graphite, graphene or CNT nanotubes.

[0287] In the ordinary moving mode and the flying motion mode of the above-mentioned snow-making refrigeration equipment of the present invention, during the ice-making and snow-making process in which the fluid supply device sprays water mist into the refrigeration chamber, the water mist entering the refrigeration chamber is cooled and quickly crystallizes on the cold gathering body and the upper surface of the cold gathering body or the cold conducting structure arranged on the surface. When the space of the refrigeration chamber is large, most of the cold source air will remain in the refrigeration chamber. The cold air in the refrigeration chamber can easily dissipate outwards from the ice and snow cold source outlet of the machine body along with the snowflakes. In order to enhance the contact between the structure in the refrigeration chamber and the cold air and reduce the redundant space in the refrigeration chamber, the above-mentioned snow-making refrigeration equipment of the present invention in the ordinary moving mode and the flying motion mode also includes a snow-forming body arranged in the refrigeration chamber and connected in a rigid or flexible manner.

[0288] refer to Fig.10 —12. Fig.16 Fig.17 Fig.25As shown, the snow-forming body is a metal mesh body 4b or a metal sheet body 4c or a metal truss body 4d or a metal ring tube body 4e. Further, the metal mesh body 4b or the metal sheet body 4c or the metal truss body 4d or the metal ring tube body 4e is fixedly connected to the cooling body 4 in the cooling cavity 41. Or the metal mesh body 4b or the metal sheet body 4c or the metal truss body 4d or the metal ring tube body 4e is flexibly connected to the cooling body 4 in the cooling cavity 41.

[0289] As an option, the snow-forming body is a metal mesh body 4b or a metal sheet body 4c or a metal truss body 4d or a metal ring tube body 4e and a spring 4f flexibly connected to the cooling body 4.

[0290] Optionally, the snow-forming body is a metal mesh body 4b or a metal sheet body 4c or a metal truss body 4d or a metal ring tube body 4e and a rubber column 4g is flexibly connected to the cooling body 4.

[0291] In the ordinary moving mode and the flying movement mode of the snow-making refrigeration device of the present invention, in order to enhance the contact between the structure in the refrigeration cavity and the cold air and reduce the redundant space in the refrigeration cavity, this embodiment is described by taking the snow-making refrigeration device in which four cooling bodies are spliced ​​and arranged to form a refrigeration cavity as an example. Fig.16 Fig.17 As shown, a cooling structure having a heat conducting fin 4a is provided on the non-contact end surface of the cooling body 4 and the semiconductor cooling sheet 2.

[0292] When the water mist enters the refrigeration chamber, it encounters cold and quickly crystallizes on the heat transfer fins of the cooling body. When the agitation device vibrates the cooling body, the ice crystals fall off and gather downward in the gap between the heat transfer fins of the cooling body at the lower end of the refrigeration chamber. The ice chips that fall into the gap between the heat transfer fins are difficult to be discharged from the machine under the action of airflow and inertia.

[0293] In order to solve the above technical problem of a large amount of ice chips remaining in the gaps between the heat transfer fins of the cooling body, the specific Fig.16 As shown, this embodiment is explained by taking four cooling bodies spliced ​​and arranged to form a snowmaking refrigeration device with a refrigeration chamber as an example, the metal mesh body 4b is suspended on the cooling body 4 by a spring 4f, and the heat-conducting fins 4a on the cooling body 4 penetrate the metal mesh body 4b, and the mesh bars of the metal mesh body 4b separate the gaps between the heat-conducting fins 4a of the cooling body 4 to form a hierarchical structure.

[0294] Specific Fig.17 As shown, this embodiment is explained by taking four cooling bodies spliced ​​and arranged to form a snowmaking refrigeration device with a refrigeration chamber as an example, the metal ring tube body 4e is suspended on the cooling body 4 by a spring 4f, and the metal ring tube body 4e is arranged in a surrounding manner in the gap between the heat-conducting fins 4a of the cooling body 4, and the metal ring tube body 4e separates the gap between the heat-conducting fins 4a of the cooling body 4 to form a hierarchical structure.

[0295] In the above three embodiments of the snow-making refrigeration equipment of the present invention, Fig.16 Fig.17 Fig.25 As shown, the metal mesh body 4b and the metal ring tube body 4e are elastically connected to the cooling body 4 through the spring 4f. The metal mesh body 4b and the metal ring tube body 4e not only have a secondary vibration function relative to the cooling body 4, but also the snow-forming body absorbs the cold energy emitted by the semiconductor refrigeration plate 2 in the refrigeration chamber 41, and the water mist entering the refrigeration chamber is crystallized in the snow-forming body, so that it has a better auxiliary snow and ice making function.

[0296] refer to Fig.16 Fig.17 As shown, the snow-forming body separates the gaps between the heat-conducting fins 4a of the cooling body 4 into a hierarchical structure. During the process of making ice and snow by the fluid supply device spraying water mist into the refrigeration chamber 41, when the agitation device vibrates the cooling body 41, ice crystals will fall downward onto the metal mesh 4b or the metal ring tube 4e between the heat-conducting fins 4a of the cooling body 4 at the lower end of the refrigeration chamber 41. When the agitation device vibrates the cooling body 4, the metal mesh 4b and the metal ring tube 4e also vibrate simultaneously with the cooling body 41, and the ice chips that fall into the gaps between the heat-conducting fins 4a of the cooling body 4, the metal mesh 4b and the metal ring tube 4e are easily discharged from the machine body 1 through the ice and snow cold source outlet 1c under the action of airflow and inertial force.

[0297] In the normal moving mode and the flying movement mode of the above-mentioned snow-making refrigeration equipment of the present invention, the ice crystals or snowflakes formed in the refrigeration chamber are naturally discharged outwardly from the machine body through the ice and snow cold source outlet. In order to prevent the ice crystals or snowflakes from being accumulated in the refrigeration chamber due to failure to be removed in time, thereby affecting the snow-making and ice-making effect of the snow-making refrigeration equipment, the snow-making refrigeration equipment of the present invention is also provided with a second strong discharge mode for the ice crystals or snowflakes to be discharged outwardly through the ice and snow cold source outlet.

[0298] Specific Fig.26 As shown, the snowmaking refrigeration equipment of the present invention has a boosting chamber 1z disposed on the body 1 near the air inlet Ⅱ1b, the boosting fan 5c is disposed between the boosting chamber 1z and the air inlet Ⅱ1b, and the air inlet Ⅱ1b, the boosting fan 5c and the boosting chamber 1z form a boosting channel in the body 1. The air gathering port 1z1 of the boosting chamber 1z is disposed toward the boosting fan 5c, and the pressure relief port 1z2 of the boosting chamber 1z is disposed toward the refrigeration chamber 41 or the ice and snow cold source outlet 1c.

[0300] refer to Fig.26 Fig. 27 As shown, in the snow-making refrigeration equipment of the present invention, when ice crystals or snowflakes in the refrigeration chamber 41 cannot be discharged smoothly through the ice and snow cold source outlet 1c under natural conditions and accumulate in the refrigeration chamber 41, the booster fan 5c or the static pressure electric fan 5d is powered on by the power supply component under the control of the main control circuit board 7 and blows strong air into the booster chamber 1z, and the super strong wind pressure blows from the pressure relief port of the booster chamber 1z to the ice and snow cold source outlet 1c. At the same time, with the cooperation of the agitation device in the body 1, the ice crystals or snowflakes are quickly discharged out of the body 1 through the ice and snow cold source outlet 1c along with the strong wind in the refrigeration chamber 41.

[0301] Specific Fig. 27 As shown, the snowmaking refrigeration equipment of the present invention is provided with an impeller 1y between the pressure relief port 1z2 of the pressurizing chamber 1z and the ice and snow cold source outlet 1c. A portion of the impeller 1y passes through the ice and snow cold source outlet 1c and is disposed deep in the refrigeration chamber 41, and another portion thereof is disposed toward the pressure relief port 1z2 of the pressurizing chamber 1z. The impeller 1y can rotate under the blowing of the gas in the pressurizing chamber 1z.

[0302] refer to Fig.26 Fig. 27 As shown, when the volume of ice crystals or snowflakes in the refrigeration chamber 41 discharged outward through the ice and snow cold source outlet 1c under the strong blowing state in the boost chamber 1z is too large,
