[0027] In vehicle refrigeration equipment, the compressor is typically exposed to the air. During operation, it generates vibration and noise, which can be transmitted to other components through its connections. To reduce noise during operation, some technologies use elastic feet to secure the compressor to its mounting base. However, these feet primarily dampen vertical vibrations, offering limited overall noise reduction. The compressor still generates significant noise and vibration, negatively impacting vehicle comfort.
[0028] Therefore, this utility model proposes a vehicle with refrigeration equipment, which aims to effectively reduce the vibration and noise of the compressor during operation.
[0029] In the embodiments of this utility model, such as Figure 1 and Figure 2 As shown, the vehicle includes a frame and a refrigeration device disposed on the frame. The refrigeration device includes a compressor, which includes a housing 100 and a damping structure 200. The damping structure 200 at least partially covers the outer surface of the housing 100.
[0030] The housing 100 serves to protect the internal components of the compressor. When the compressor is running, the internal components such as the motor and pump generate significant vibrations and noise, which are transmitted to the housing 100 and then radiated outwards. In this embodiment, a damping structure 200 is provided on at least a portion of the outer surface of the housing 100. The interior of this damping structure 200 vibrates with the compressor housing 100, thereby converting the compressor's vibration energy into heat energy and dissipating it. This significantly reduces the transmission of vibration energy and noise radiation, greatly improving the compressor's vibration and noise levels.
[0031] In addition, the damping structure 200 has poor thermal conductivity, which can reduce the heat exchange between the compressor housing 100 and the outside environment to a certain extent, thereby improving the compressor performance.
[0032] It should be noted that this embodiment utilizes the characteristic of the damping structure 200 itself that its damping material can dissipate vibration energy. Compared with the method of using sound-absorbing cotton to reduce noise in related technologies, this embodiment directly reduces the generation of noise by reducing vibration, thus achieving a better noise reduction effect.
[0033] Understandably, the specific structural form of the damping structure 200 can be determined according to the actual situation, and can be a coating structure, a sheet structure, a sleeve structure or other structures.
[0034] The damping structure 200 at least partially covers the outer surface of the housing 100. Understandably, the damping structure 200 may completely cover the outer surface of the housing 100 or only cover a portion of the outer surface of the housing 100. In order to achieve better vibration reduction and noise reduction effects, in practical applications, the damping structure 200 may completely cover the outer surface of the housing 100 to achieve better isolation of vibration and noise transmission.
[0035] Alternatively, the refrigeration equipment can be an air conditioner, refrigerator, etc.
[0036] Alternatively, the vehicle can be a car, train, etc.
[0037] In summary, in this utility model, by covering at least a portion of the outer surface of the compressor housing 100 with a damping structure 200, the damping structure 200 can vibrate along with the housing 100 when the compressor is running, and can convert vibration energy into heat energy and dissipate it, thereby reducing vibration transmission and noise radiation, effectively reducing vibration and noise during compressor operation, and improving vehicle comfort.
[0038] In one embodiment of this application, as Figure 1 and Figure 2 The damping structure 200 includes at least one of a damping coating and a damping patch 210.
[0039] This embodiment illustrates the specific structure of the damping structure 200. The damping structure 200 can be a damping coating, a damping patch 210, or a combination of a damping coating and a damping patch 210.
[0040] In practical applications, the outer surface of the housing 100 may be covered only by the damping coating; or only by the damping patch 210; or the outer surface of the housing 100 may be covered by the damping coating first, and then the damping patch 210 may be set outside the damping coating; or a portion of the outer surface of the housing 100 may be covered by the damping coating and another portion may be covered by the damping patch 210, etc.
[0041] It should be noted that both the damping coating and the damping patch 210 can reduce vibration and thus noise, but they differ in their specific installation and usage effects.
[0042] Taking the damping patch 210 as an example, the damping patch 210 can be adhesively applied to cover the housing 100. It is less affected by the production environment and can be directly applied in various situations. Even if the product is already in use, the damping patch 210 can be applied on-site, facilitating modifications. Furthermore, after the damping patch 210 is applied, the compressor can be put into use immediately without waiting for curing, saving time and improving production efficiency. The damping patch 210 is solid, making it easier to transport and use, and it does not generate much waste, thus contributing to environmental protection.
[0043] Taking a damping coating as an example, the damping coating can be applied to cover the housing 100. Its effectiveness is minimally affected by the shape of the housing 100, and it is suitable for components of various shapes, offering flexible application options. Optionally, the damping coating includes at least one layer of a water-based damping coating, a wide-temperature-range damping coating, a low-temperature-range damping coating, and a high-temperature-range damping coating. The water-based damping coating can be an acrylic-based water-based coating, which has a wide range of applications, is pollution-free, and is environmentally friendly. In practical applications, a wide-temperature-range damping coating can be understood as a coating with good damping effect at operating temperatures from -40℃ to 80℃; a low-temperature-range damping coating can be understood as a coating with good damping effect at operating temperatures below 0℃; and a high-temperature-range damping coating can be understood as a coating with good damping effect at operating temperatures above 80℃.
[0044] Understandably, the damping coating can be a single layer of the above-mentioned coatings or a multilayer structure formed by two or more of the above-mentioned coatings, so that the damping coating can maintain good damping effect and stronger stability over a wider temperature range.
[0045] In some other embodiments, a damping coating may be applied to the housing 100 first, and then a damping patch 210 may be attached to the outside of the damping coating.
[0046] In some other embodiments, the damping patch 210 can be first attached to the housing 100, and then a damping coating can be applied to the areas of the housing 100 not covered by the damping patch 210 by spraying, so as to increase the coverage area of the damping structure 200.
[0047] To achieve better vibration reduction, the composite loss factor η of the damping structure 200 is ≥0.05.
[0048] With this configuration, the damping performance of the damping structure 200 is significantly improved, resulting in a more pronounced vibration reduction effect. It can better absorb and disperse vibration energy, reduce the system's vibration response, and thus improve the overall stability and safety of the structure.
[0049] Furthermore, such as Figure 1 and Figure 2 The thickness H of the damping structure 200 satisfies: 1mm≤H≤20mm.
[0050] Understandably, the thickness H of the damping structure 200 should not be too thin or too thick. If the thickness is too thin, the vibration reduction effect of the damping structure 200 will not be good; if the thickness is too thick, it will result in an excessively large compressor size and occupy too much installation space. Based on this, in this embodiment, the thickness H of the damping structure 200 is set to satisfy 1mm≤H≤20mm, which can ensure a good vibration reduction effect without occupying too much installation space.
[0051] Optionally, the thickness H of the damping structure 200 can be 1mm, 2mm, 5mm, 7mm, 8mm, 10mm, 11mm, 13mm, 15mm, 17mm, 18mm, 19mm or 20mm, etc.
[0052] It should be noted that, in order to achieve better vibration reduction effect without taking up too much installation space, the thickness of the damping coating or damping patch 210 can be set within the above range.
[0053] In one embodiment of this application, the damping structure 200 may include at least one of a free damping structure and a constrained damping structure.
[0054] Understandably, a free damping structure consists of a high internal damping layer firmly bonded to the base plate, with the thickness of the damping layer generally being 1-4 times the thickness of the base plate. A constrained damping structure involves attaching a thin layer of material with a high elastic modulus (such as a metal foil layer) to the outside of the free damping layer. This outer thin layer constrains the damping layer, increasing its shear deformation and achieving a better vibration reduction effect.
[0055] Optionally, the damping patch 210 formed by the free damping structure can be a single-layer structure composed of composite material damping sheets or damping coating prefabricated sheets, or a multi-layer structure composed of several types.
[0056] Optionally, the constrained damping structure includes a damping layer and a constrained layer, with the constrained layer located outside the damping layer. The damping layer facilitates vibration reduction and noise reduction; the constrained layer causes shear deformation when the damping layer deforms, dissipating more energy and enhancing the vibration reduction and noise reduction effect. In this technical solution, the damping layer of the damping patch 210 formed by the constrained damping structure is a single-layer structure or a multi-layer structure composed of one or more of the following: rubber sheet, asphalt sheet, foam damping sheet, composite material damping sheet, or pre-fabricated damping coating. The constrained layer is one of the following: metal, rigid polymer material, or composite material.
[0057] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
