Description
Technical Field
[0001] The utility model belongs to the technical field of refrigeration units, and more specifically relates to a refrigeration unit capable of preventing a compressor from overheating. Background Art
[0002] A refrigeration unit is a device used to reduce the temperature or maintain a low temperature in a specific environment. It is widely used in fields such as air conditioning, industrial refrigeration, cold storage and cold chain logistics. A refrigeration unit usually consists of a compressor, condenser, expansion valve, evaporator and control system.
[0003] The compressor is responsible for compressing low-pressure refrigerant vapor into high-pressure vapor and is the heart of the refrigeration cycle. The compressor in the existing refrigeration unit will overheat after long-term use. Overheating of the compressor will reduce the refrigeration effect and increase energy consumption. Long-term overheating will shorten the service life of the compressor.
[0004] Although a refrigeration system is added in the prior art to prevent the compressor temperature from being too high, the refrigeration system will age after long-term use, and various dirt and dust will be absorbed on the refrigeration system, resulting in a poor cooling effect on the compressor, which needs to be improved. Utility Model Content
[0005] In view of the deficiencies in the prior art, the purpose of the utility model is to provide a refrigeration unit for preventing compressor overheating, which has the advantage of preventing the compressor temperature from being too high.
[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:
[0007] A refrigerator unit for preventing compressor overheating, comprising a refrigerator chassis and a compressor located in the refrigerator chassis, a cooling component for cooling the compressor installed next to the compressor, the cooling component comprising: a U-shaped plate, a screw rod rotatably installed on the U-shaped plate, a motor installed on the upper surface of the U-shaped plate, the output end of the motor and the screw rod rotatably connected through a coupling, a sliding hole is opened on the U-shaped plate, a C-shaped cooling ring for cooling the compressor is threadedly connected on the screw rod, the C-shaped cooling ring is connected to the output port of a micro air cooler through a hose, and a side wall of the C-shaped cooling ring is opened with a plurality of air outlet holes;
[0008] The cooling component also includes a temperature sensor installed on the side wall of the U-shaped plate, and a reciprocating component installed on the U-shaped plate. The temperature sensor is electrically connected to the motor and the micro air cooler through wires and a controller.
[0009] The advantages of this scheme are at least that: when the temperature of the compressor is too high, the temperature sensor recognizes that the temperature of the compressor is too high. At this time, the controller controls the motor to start. The controller controls the motor to start and also controls the micro air cooler to start, and delivers cold air to the C-type cooling ring through a hose. The cold air blows the cold air to the outer surface of the compressor through the air outlet holes on the C-type cooling ring, thereby cooling the compressor. The motor starts and drives the screw rod to rotate, so that the C-type cooling ring moves up and down on the U-shaped plate. Under the action of the reciprocating component, the C-type cooling ring moves back and forth on the outer wall of the compressor. When the compressor temperature drops to within the threshold range set by the temperature sensor, the controller stops the motor and the micro air cooler, thereby completing the cooling of the compressor, thereby avoiding the phenomenon of excessive temperature of the compressor during use.
[0010] The utility model is further configured as follows: a stabilizing rod is installed beside the C-shaped cooling ring, a sliding ear is provided on the C-shaped cooling ring, the C-shaped cooling ring is slidably installed on the stabilizing rod through the sliding ear, and a limiting block is installed on the top of the stabilizing rod.
[0011] The advantage of this solution is at least that the stabilizing rod can make the C-shaped cooling ring more stable during the up and down movement, thereby avoiding shaking during the movement.
[0012] The utility model is further configured as follows: the reciprocating assembly comprises: a first reciprocating switch and a second reciprocating switch respectively installed on the top surface and the bottom surface of the sliding hole for controlling the forward and reverse rotation of the motor.
[0013] The advantage of this solution is at least that: by providing a first reciprocating switch and a second reciprocating switch, the C-type cooling ring can perform reciprocating motion, thereby improving the cooling effect of the C-type cooling ring on the compressor and allowing the compressor to be cooled more quickly.
[0014] The utility model is further configured as follows: a buffer assembly is provided on the stabilizing rod, and the buffer assembly includes: a first spring is installed on one end face of the limiting block, a first buffer plate is provided at an end of the first spring away from the limiting block, and also includes a second spring and a second buffer plate provided at an end of the stabilizing rod away from the limiting block, and the first buffer plate, the second spring, the second buffer plate and the second spring are all sleeved on the outer wall of the stabilizing rod.
[0015] The advantages of this scheme are at least that the arrangement of the first buffer plate, the second spring and the second buffer plate and the second spring plays a buffering role when the C-type cooling ring contacts the first reciprocating switch and the second reciprocating switch, thereby preventing the C-type cooling ring from directly contacting the first reciprocating switch and the second reciprocating switch and colliding with each other, thereby reducing the service life of the first reciprocating switch and the second reciprocating switch.
[0016] The utility model is further configured as follows: silicone sheets are adhered to surfaces of the first buffer plate and the second buffer plate that are in contact with the sliding ears.
[0017] The advantage of this solution is at least that the silicone sheet plays a buffering role when the sliding ear contacts the first buffer plate and the second buffer plate, thereby preventing the sliding ear from colliding with the first buffer plate and the second buffer plate for a long time, thereby reducing their service life.
[0018] The utility model is further configured as follows: a protective shell is fixed to the outer wall of the U-shaped plate by bolts.
[0019] The advantage of this solution is at least that the provision of the protective shell prevents dirt from being entangled on the screw rod, thereby causing the screw rod to be unusable.
[0020] The utility model is further configured as follows: a filter screen is installed on each of the air outlets.
[0021] The advantage of this solution is at least that the filter can prevent dirt and debris from entering the C-type cooling ring, thereby blocking the air outlet.
[0022] In summary, the utility model has at least the following advantages:
[0023] 1. By setting a cooling component, a temperature sensor and a reciprocating component, when the temperature of the compressor is too high, the temperature sensor recognizes that the temperature of the compressor is too high. At this time, the controller controls the motor to start. The controller controls the motor to start and also controls the micro air cooler to start, and delivers cold air to the C-type cooling ring through a hose. The cold air blows the cold air to the outer surface of the compressor through the air outlet on the C-type cooling ring, thereby cooling the compressor. The motor starts and drives the screw rod to rotate, so that the C-type cooling ring moves up and down on the U-shaped plate. Under the action of the reciprocating component, the C-type cooling ring moves back and forth on the outer wall of the compressor. When the compressor temperature drops to the threshold range set by the temperature sensor, the controller stops the motor and the micro air cooler, and the compressor is cooled, thereby avoiding the phenomenon of excessive temperature of the compressor during use;
[0024] 2. By setting a stabilizing rod, the stabilizing rod can make the C-type cooling ring more stable during the up and down movement, avoiding shaking during the movement; by setting a protective shell, the protective shell can prevent dirt from being entangled on the screw rod, thereby causing the screw rod to be unusable; the filter installed on the air outlet can prevent dirt and debris from entering the C-type cooling ring, thereby blocking the air outlet;
[0025] 3. By arranging the first buffer plate, the first spring, the second buffer plate and the second spring, a buffering effect is played when the C-type cooling ring contacts the first reciprocating switch and the second reciprocating switch, thereby preventing the C-type cooling ring from directly contacting the first reciprocating switch and the second reciprocating switch and colliding with each other, thereby reducing the service life of the first reciprocating switch and the second reciprocating switch.

[0031] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0033] like Figure 2 As shown (refer to Figure 4), in some embodiments, the cooling component 3 includes: a U-shaped plate 301, a screw rod 302 is rotatably mounted on the U-shaped plate 301, a motor 303 is mounted on the upper surface of the U-shaped plate 301, the output end of the motor 303 is rotatably connected to the screw rod 302 through a coupling, a sliding hole 4 is provided on the U-shaped plate 301, a C-shaped cooling ring 304 for cooling the compressor 2 is threadedly connected to the screw rod 302, the C-shaped cooling ring 304 is connected to the output port of the micro air cooler (not shown in the figure) through a hose 12, and a side wall of the C-shaped cooling ring 304 is provided with a plurality of air outlets 5. It is worth mentioning that in order to prevent the air outlets 5 on the C-shaped cooling ring 304 from being blocked by dirt and debris, a filter 11 is installed on the air outlet 5. In order to ensure that the screw rod 302 will not be entangled with dirt and debris, a protective shell 10 is fixed to the outer wall of the U-shaped plate 301 by bolts.
[0034] like Figure 3 As shown, the cooling component 3 also includes a temperature sensor 305 installed on the side wall of the U-shaped plate 301, and a reciprocating component 306 installed on the U-shaped plate 301. The temperature sensor 305 is electrically connected to the motor 303 and the micro air cooler through wires and a controller.
[0035] like Figure 2 , Figure 3 As shown, in order to ensure that the C-type cooling ring 304 is more stable during the up and down movement, in some preferred embodiments, a stabilizing rod 6 is installed next to the C-type cooling ring 304, and a sliding ear 3041 is provided on the C-type cooling ring 304. The C-type cooling ring 304 is slidably installed on the stabilizing rod 6 through the sliding ear 3041, and a limiting block 7 is installed on the top of the stabilizing rod 6.
[0036] The reciprocating assembly 306 includes a first reciprocating switch 3061 and a second reciprocating switch 3062 respectively mounted on the top and bottom surfaces of the sliding hole 4 for controlling the forward and reverse rotation of the motor 303 .
[0037] In order to prevent the C-type cooling ring 304 from directly contacting the first reciprocating switch 3061 and the second reciprocating switch 3062 and causing a collision, in some embodiments, a buffer assembly 8 is provided on the stabilizing rod 6, and the buffer assembly 8 includes: a first spring 801 is installed on one end face of the limit block 7, and a first buffer plate 802 is provided at the end of the first spring 801 away from the limit block 7, and also includes a second spring 803 and a second buffer plate 804 arranged at the end of the stabilizing rod 6 away from the limit block 7, and the first buffer plate 802, the second spring 803, the second buffer plate 804, and the second spring 803 are all mounted on the outer wall of the stabilizing rod 6.

The motor 303 starts and drives the screw rod 302 to rotate, so that the C-type cooling ring 304 moves up and down on the U-shaped plate 301.
[0041] Under the action of the reciprocating component 306, the C-type cooling ring 304 moves back and forth on the outer wall of the compressor 2. When the C-type cooling ring 304 contacts the first reciprocating switch 3061 and the second reciprocating switch 3062, under the action of the first buffer plate 802, the first spring 801, the second buffer plate 804, and the second spring 803, a buffering effect is played to prevent the C-type cooling ring 304 from directly contacting the first reciprocating switch 3061 and the second reciprocating switch 3062 and colliding, thereby reducing the service life of the first reciprocating switch 3061 and the second reciprocating switch 3062.
[0042] When the temperature of the compressor 2 drops to within the temperature threshold range set by the temperature sensor 305, the motor 303 and the micro air cooler are stopped by the controller, thereby completing the cooling of the compressor 2, thereby preventing the compressor 2 from overheating during use.
