[0003] The working principle of the refrigeration device is roughly as follows: the compressor runs, sucking in low-temperature and low-pressure refrigerant gas, and discharging high-temperature and high-pressure gas into the condenser after compression. After heat dissipation, it becomes a high-pressure liquid, and after throttling and pressure reduction through capillary tubes, it enters the evaporator, absorbs heat in the evaporator, evaporates into a gas, and then returns to the compressor. This cycle is repeated to achieve continuous cooling of the freezer.

Some commercial freezers may have more powerful refrigeration devices to meet the refrigeration needs of a large number of items. Utility Model Content

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Example

[0025] like Figure 1-4 As shown, a freezer refrigeration device proposed in an embodiment of the utility model includes a freezer mounting plate 1, a compressor 2, a condenser 3 and an evaporator 5. The outlet of the condenser 3 is connected to the inlet of the evaporator 5 through a capillary tube. Specifically, the outlet of the condenser 3 is connected to the inlet of the expansion valve (throttling device) through a pipeline. The condensed refrigerant is throttled and depressurized at the expansion valve. The outlet of the expansion valve is connected to the inlet of the evaporator 5. The evaporator 5 is installed around the refrigeration space inside the cabinet and is connected to the capillary tube through a pipeline. A cushion block 6 is provided on the freezer mounting plate 1. An upper fixed block 7 is fixedly installed inside the cushion block 6, a conical tube 9 is fixedly installed at the axis of the upper fixed block 7, a damping shaft 10 is movably inserted inside the conical tube 9, a spring 11 is fixedly sleeved outside the conical tube 9 and the damping shaft 10, one end of the spring 11 is fixedly connected to a lower fixed block 8, and the lower fixed block 8 is fixedly connected to the refrigerator mounting plate 1, the compressor 2 is connected to the condenser 3 through a copper tube structure 4, and the copper tube structure 4 includes a large copper tube 41 connected to the compressor 2 and a small copper tube 42 connected to the evaporator 5;

[0026] Freezer mounting plate 1: provides the installation base for the entire refrigeration unit;

[0027] Pad 6: It plays the role of supporting the compressor 2. By setting two symmetrical pads 6, the installation of the compressor 2 can be made more stable.

[0028] The upper fixing block 7, the conical cylinder 9, the damping shaft 10, the spring 11 and the lower fixing block 8 form a shock-absorbing structure. The principle is that when the compressor 2 generates vibration during operation, the damping shaft 10 moves in the conical cylinder 9, compressing or stretching the spring 11 at the same time, and utilizing the elastic deformation of the spring 11 to absorb and buffer the vibration, thereby reducing the impact of the vibration of the compressor 2 on the entire device and the cabinet, and playing a role in reducing vibration, noise and improving stability.

[0029] Compressor 2: It is the power source of the refrigeration system, compressing the low-temperature and low-pressure refrigerant gas into high-temperature and high-pressure gas. Its principle is to achieve the change of gas state through mechanical work.

[0030] Condenser 3: The high-temperature and high-pressure refrigerant gas dissipates heat here and turns into high-pressure liquid, using the principle of heat exchange to achieve cooling.

[0031] Copper tube structure 4:

[0032] Large copper tube 41: has a larger diameter and is used to transmit high-pressure refrigerant gas.

[0033] Small copper tube 42 : has a smaller diameter, may be used to transmit the refrigerant liquid after throttling, and is connected to the evaporator 5 .

[0034] Rubber pad 43: plays the role of sealing and shock absorption, reducing the vibration transmission and leakage risk of the copper pipe connection part.

[0035] Evaporator 5: Liquid refrigerant absorbs heat here and evaporates into gas, lowering the temperature inside the freezer. The principle is to use the phase change of the refrigerant to absorb heat. This part is a refrigeration technology with an existing structure, and the principle will not be elaborated in this application.

[0036] like Figure 1 As shown, in some embodiments, the upper end of the pad 6 is fixedly connected to the compressor 2, and the pad 6 consists of two blocks 6 that are symmetrically arranged and fixed on both sides of the compressor 2; to a certain extent, it can help absorb and disperse the vibration energy transmitted from the compressor 2 and reduce the impact on the surrounding structure and the entire system.

[0037] like Figure 3 As shown, in some embodiments, the diameter of the large copper tube 41 is larger than the diameter of the small copper tube 42, which can adapt to vibration while ensuring the stability of the structure.

[0038] like Figure 3 As shown, in some embodiments, a rubber pad 43 is provided between the large copper tube 41 and the small copper tube 42. The rubber pad 43 can adapt to the thermal expansion and contraction of the copper tube due to temperature changes to a certain extent, reduce the stress of the connection part, and can reduce the collision sound to a certain extent.

[0039] like Figure 4As shown, in some embodiments, one end of the damping shaft 10 is plugged into the bottom of the conical cylinder 9, and the other end does not contact the top of the conical cylinder 9; when the compressor 2 generates vibration, the damping shaft 10 can move relatively in the conical cylinder 9. Since one end is plugged into the bottom and the other end does not contact the top, this movement has a certain directionality and constraint. In this way, the vibration energy can be more effectively converted into friction heat energy between the damping shaft 10 and the conical cylinder 9, thereby achieving a more accurate and efficient shock absorption effect. At the same time, this structural design also helps to maintain the stability and reliability of the shock absorption structure, avoiding structural failure or performance degradation due to excessive movement or improper contact. And during the shock absorption process, no additional obstruction or adverse effect will be generated due to contact with the top of the conical cylinder 9, ensuring the smooth operation of the shock absorption mechanism.

[0040] like Figure 2 As shown, in some embodiments, the shape of the spring 11 is that the diameters at the upper and lower ends are large and the diameter in the middle is small; the large diameters at the upper and lower ends can provide a larger elastic restoring force, and can better absorb and buffer energy when the compressor 2 vibrates more strongly; the small middle diameter can increase the flexibility of the spring 11, so that it can effectively play a role even under a smaller vibration amplitude, thereby providing good shock absorption performance under various vibration conditions.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
