[0002] A refrigerator is a machine that transfers heat from a cooled object with a lower temperature to the ambient medium to obtain cooling capacity. The heat transferred from the lower temperature object is usually called cooling capacity. The working fluid involved in the thermodynamic process changes (energy conversion and heat transfer) in the refrigerator is called refrigerant. The refrigeration temperature range is usually above 120K, and below 120K belongs to the deep low temperature technology range. Refrigerator is widely used in industrial and agricultural production and daily life.

Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art that the temperature of the refrigeration unit is high, which will cause the unit to run at high load and reduce the refrigeration efficiency of the refrigeration unit, and to propose a high-efficiency cold storage refrigeration unit.

The base is provided with a lifting assembly for controlling the height adjustment of the four movable universal wheels;

[0009] A cooling assembly is provided at the top of the base and is used to cool the condenser in the refrigeration unit body;

[0010] And a swing component used in conjunction with the cooling component, wherein the swing component is used to drive the cooling component to swing for cooling.

[0011] Material toggling mechanism, its both sides respectively have a cylinder pressure, and the cylinder pressure bar connects swing arm, and the swing arm end face has hook portion, and a bar passes position between the end of two swing arms and the hook portion.

[0012] In one possible design, the cooling assembly includes two support columns fixed to the top of the base, a rotating shaft rotates inside the two support columns, a connecting plate is fixed to the surface of the rotating shaft, and a plurality of atomizing nozzles are fixedly connected to the side ends of the connecting plate. A water tank is fixed to the top of the base, and a booster water pump is fixed to the top of the water tank. The water inlet of the booster water pump is connected to the water tank, and the water outlet of the booster water pump is connected to the connecting plate.

[0013] In a possible design, the water tank is made of transparent acrylic material.

[0014] In one possible design, the swing assembly includes a vertical plate fixed to the top of the base, a second groove is opened in the vertical plate, a half-tooth ring slides in the second groove, a half-tooth gear intermittently meshed with the half-tooth ring rotates in the second groove, a connecting slider is fixed to the side end of the half-tooth ring, a driving rack is fixed to the side end of the connecting slider, a driven gear meshed with the driving rack is fixed on the surface of the rotating shaft, a driving motor is fixed to the side end of the vertical plate, and the driving motor is fixed to the half-tooth gear through a coupling.

This is an endothermic process, which effectively takes away the heat generated by the condenser. By starting the drive motor to drive the half-tooth gear to rotate, the rotation of the half-tooth gear drives the half-tooth gear ring to perform reciprocating linear motion in the second groove. The half-tooth gear ring drives the driving rack to perform linear reciprocating motion through the connecting slider, and the driving rack drives the driven gear to rotate back and forth. The driven gear drives the connecting plate to swing through the rotating shaft, and the connecting plate drives the atomizing nozzle to swing and spray, thereby expanding the coverage of the water mist.
