Description

Technical Field

[0001] This utility model relates to the field of heat pump unit technology, specifically a shock absorption device for heat pump units. Background Technology

[0002] A heat pump unit is a device that transfers heat energy from a low-temperature heat source to a high-temperature heat source. It directly absorbs heat from the air and converts it into high-grade heat energy to provide heating and hot water. It has a wide range of applications. Heat pump units have relatively few components, and the main moving part is the compressor. Through long-term technological development and optimization, it has high operational stability.

[0003] However, existing technologies still have many defects in some similar structures when used in practice. For example, if the heat pump unit cannot effectively absorb and consume vibration energy, the vibration reduction effect will be weak, which will cause the fixing bolts of key components such as compressor, heat exchanger, and pipe interface to loosen, or even cause component displacement or breakage. At the same time, if heat dissipation cannot be effective, heat will accumulate inside the unit, causing multiple adverse consequences and directly affecting the performance, life and safety of the equipment.

[0004] To address the aforementioned problems, the inventors proposed a vibration damping device for heat pump units. Utility Model Content

[0005] In order to solve the problems of weak vibration damping effect due to inconvenience in absorbing and consuming vibration energy and low heat dissipation function due to inability to remove heat generated by the unit, the purpose of this utility model is to provide a vibration damping device for heat pump units.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a heat pump unit vibration damping device, including a housing, a heat dissipation device on the top surface of the housing, a vibration damping component inside the housing, the vibration damping component including a body and multiple fixing plates, one side of the fixing plate being fixedly connected to the inner wall of the housing, multiple first spring dampers being fixedly connected to the bottom surface of the body, multiple second spring dampers being fixedly connected to the upper part of the body, and a movable block being fixedly connected to the end of the second spring damper.

[0007] As a preferred technical solution of this application, the heat dissipation device includes a box cover, a protective shell is provided on the top surface of the box cover, a dustproof net is fixedly connected to the top surface of the protective shell, a bracket is fixedly connected to the inner wall of the protective shell, a fan is provided between the dustproof net and the bracket, and a plurality of retaining rings arranged in a ring array are fixedly connected to the outer surface of the protective shell.

[0008] Through the above technical solution, the cover, as the basic component of the heat dissipation device, provides protection for internal components such as the fan on its top surface, preventing external debris from entering. The dustproof net is located on the top surface of the protective shell, which can block dust and larger particles of debris, ensuring that the air entering the heat dissipation device is clean and avoiding dust accumulation that could affect the performance of the fan and the internal components of the unit. The bracket is cross-shaped and fixed to the inner wall of the protective shell to support the fan and ensure its stable operation. After the fan starts, it draws outside air into the protective shell. The retaining rings and bolts are used to fix the protective shell to the cover, ensuring the structural stability of the heat dissipation device. Air enters the interior of the box through the ventilation slots on the top surface of the cover, which can effectively remove the heat generated by the unit and achieve the heat dissipation function.

[0009] As a preferred technical solution of this application, multiple heat dissipation slots are provided on both sides of the box.

[0010] Through the above technical solution, the heat dissipation slot forms an air circulation channel, and hot air is discharged from the top of the box, which accelerates air convection and improves heat dissipation efficiency.

[0011] As a preferred technical solution of this application, a movable groove for use with the movable block is provided on one side of the fixed plate.

[0012] With the above technical solution, the movable block can slide within the movable groove opened on one side of the fixed plate.

[0013] As a preferred technical solution of this application, the bracket is cross-shaped.

[0014] With the above technical solution, the bracket is fixed in a cross shape to the inner wall of the protective shell to support the fan and ensure the stable operation of the fan.

[0015] As a preferred technical solution of this application, a bolt is inserted into the inner wall of the retaining ring, and the bottom end of the bolt extends into the box cover.

[0016] Through the above technical solution, the retaining ring and bolts are used to fix the protective shell to the cover, ensuring the structural stability of the heat dissipation device.

[0017] As a preferred technical solution of this application, the top surface of the box cover is provided with a ventilation groove.

[0018] With the above technical solution, air enters the interior of the box through the ventilation slots on the top surface of the box cover.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] This invention can reduce the downward transmission of vibration to the housing through the elastic deformation of the first spring damper and the action of the damping medium. Multiple second spring dampers and movable blocks on the upper part of the housing work together. The movable blocks can slide in the movable groove opened on one side of the fixed plate. When the housing vibrates laterally or longitudinally, the second spring dampers will produce corresponding elastic deformation to buffer and offset the vibration. The sliding of the movable blocks in the movable groove limits excessive displacement, thereby achieving the purpose of absorbing and consuming vibration energy and enhancing the shock absorption effect.

[0021] This invention uses a fan to draw outside air into the protective housing. Clips and bolts are used to fix the protective housing to the cover, ensuring the structural stability of the heat dissipation device. Air enters the housing through the ventilation slots on the top surface of the cover, thereby effectively removing the heat generated by the unit and achieving the purpose of heat dissipation.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Example: Figure 1-4 As shown, this utility model provides a shock absorption device for a heat pump unit, including a housing 1. Multiple heat dissipation slots 5 are provided on both sides of the housing 1. A heat dissipation device 3 is provided on the top surface of the housing 1. A shock absorption assembly 4 is provided inside the housing 1. The shock absorption assembly 4 includes a body 41 and multiple fixing plates 42. One side of the fixing plate 42 is fixedly connected to the inner wall of the housing 1. Multiple first spring dampers 43 are fixedly connected to the bottom surface of the body 41. Multiple second spring dampers 44 are fixedly connected to the upper part of the body 41. A movable block 45 is fixedly connected to the end of the second spring damper 44. A movable slot 46 for use with the movable block 45 is provided on one side of the fixing plate 42.

[0030] When the body 41 vibrates laterally and longitudinally, the second spring damper 44 will generate corresponding elastic deformation to buffer and offset the vibration. The sliding of the movable block 45 in the movable groove 46 limits excessive displacement and can absorb and consume vibration energy to enhance the shock absorption effect.

[0031] The heat dissipation device 3 includes a cover 31, a protective shell 32 on the top surface of the cover 31, a dustproof net 33 fixedly connected to the top surface of the protective shell 32, a bracket 34 fixedly connected to the inner wall of the protective shell 32, the bracket 34 being cross-shaped, a fan 35 being provided between the dustproof net 33 and the bracket 34, a plurality of retaining rings 36 arranged in a ring array fixedly connected to the outer surface of the protective shell 32, bolts 37 being inserted into the inner wall of the retaining rings 36, the bottom end of the bolts 37 extending into the cover 31, and a ventilation slot 38 being provided on the top surface of the cover 31.

[0032] After the fan 35 is started, it draws outside air into the protective shell 32. The retaining ring 36 and bolt 37 are used to fix the protective shell 32 to the cover 31 to ensure the structural stability of the heat dissipation device 3. The air enters the interior of the box 1 through the ventilation slot 38 on the top surface of the cover 31, which can effectively remove the heat generated by the unit and achieve the heat dissipation function.

[0033] The working principle of a heat pump unit vibration damping device according to an embodiment of this application is as follows: The body 41 is the core part of the heat pump unit. Multiple first spring dampers 43 fixedly connected to its bottom surface play the main role in vibration damping. When the body 41 vibrates, the first spring dampers 43 reduce the vibration transmitted downward to the housing 1 through the elastic deformation of the spring and the action of the damping medium. Multiple second spring dampers 44 and movable blocks 45 on the upper part of the body 41 work together. The movable blocks 45 can slide in the movable groove 46 opened on one side of the fixed plate 42. When the body 41 vibrates laterally and longitudinally, the second spring dampers 44 will generate corresponding elastic deformation to buffer and offset the vibration. The sliding of the movable blocks 45 in the movable groove 46 limits excessive displacement, thereby achieving the purpose of absorbing and consuming vibration energy and enhancing the vibration damping effect.

[0034] As the basic component of the heat dissipation device 3, the cover 31 has a protective shell 32 on its top surface to protect the internal components such as the fan 35 and prevent external debris from entering. The dustproof net 33 is located on the top surface of the protective shell 32 and can block dust and larger particles of debris, ensuring that the air entering the heat dissipation device 3 is clean and avoiding dust accumulation that could affect the performance of the fan 35 and the internal components of the unit. The bracket 34 is fixed in a cross shape on the inner wall of the protective shell 32 to support the fan 35 and ensure the stable operation of the fan 35. After the fan 35 is started, it draws outside air into the protective shell 32. The retaining ring 36 and bolt 37 are used to fix the protective shell 32 to the cover 31 to ensure the structural stability of the heat dissipation device 3. Air enters the interior of the housing 1 through the ventilation slot 38 on the top surface of the cover 31, thereby effectively removing the heat generated by the unit and achieving the purpose of heat dissipation.

[0035] The heat dissipation slot 5 forms an air circulation channel, and hot air is discharged from the top of the box 1, which accelerates air convection and improves heat dissipation efficiency.

[0036] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
