Description

Technical Field

[0001] This utility model relates to the field of heat pump sound insulation technology, specifically a sound insulation protective cover for heat pump units. Background Technology

[0002] As a highly efficient heat energy conversion device, heat pump units have been widely used in industrial production and civil applications due to their significant advantages such as energy saving, environmental protection, and stability.

[0003] Nowadays, heat pump units typically consist of components such as a compressor, condenser, evaporator, and fan. During operation, the compressor compresses the low-temperature, low-pressure gaseous refrigerant into a high-temperature, high-pressure gaseous state. The refrigerant then enters the condenser. In air-cooled units, the fan drives air through finned tubes, causing the refrigerant to release heat to the air and condense into a high-temperature, high-pressure liquid. The mixed refrigerant then enters the evaporator. In air-cooled units, the fan drives air through the fins, causing the refrigerant to absorb heat from the air and evaporate into a low-temperature, low-pressure gaseous state. Finally, the low-temperature, low-pressure gaseous refrigerant returns to the compressor, starting a new cycle. This process meets the heating and cooling needs of daily life.

[0004] However, during the operation of a heat pump unit, the operation of various components generates noise to varying degrees, affecting the surrounding environment and users. If the noise cannot be effectively controlled, it can also disturb residents' rest and sleep at night. Therefore, we propose a soundproof protective cover for heat pump units to effectively address these drawbacks. Utility Model Content

[0005] The purpose of this utility model is to provide a soundproof protective cover for heat pump units to solve the problems mentioned in the background art.

[0006] This utility model is achieved through the following technical solution: a soundproof protective cover for a heat pump unit, including a soundproof frame. The side projection shape of the soundproof frame is U-shaped. A left soundproof plate and a right soundproof plate are slidably disposed between the upper and lower side walls of the soundproof frame along its own length direction. The left soundproof plate and the right soundproof plate are respectively located on the left and right sides of the soundproof frame. A front protective door is hinged to the left soundproof plate and is located on the front side of the soundproof frame. A rear protective door is hinged to the right soundproof plate and is located on the rear side of the soundproof frame. The soundproof frame, the left soundproof plate, the right soundproof plate, the front protective door, and the rear protective door cooperate with each other to form a cuboid cover structure to enclose the heat pump unit.

[0007] Optionally, both the left and right sound insulation panels are U-shaped, with their openings facing each other, and sound-absorbing panels sliding along the length of the sound insulation frame on their inner sides.

[0008] Optionally, when the front protective door is rotated around the hinge axis by at least 30°, the sound-absorbing plate on the left sound insulation panel can slide out to the outside of the left sound insulation panel; when the rear protective door is rotated around the hinge axis by at least 30°, the sound-absorbing plate on the right sound insulation panel can slide out to the outside of the right sound insulation panel.

[0009] Optionally, two slide rails are fixedly provided on the upper and lower inner sidewalls of the sound insulation frame. The slide rails are distributed along the length of the sound insulation frame. The two slide rails located on the same sidewall of the sound insulation frame are symmetrically distributed from left to right. The slide rails on the left and right sides are used for sliding connection of the left sound insulation panel and the right sound insulation panel, respectively.

[0010] Optionally, the left sound insulation panel can slide out of the outside of the slide rail from both the front and rear sides of the left slide rail of the sound insulation frame, and the right sound insulation panel can slide out of the outside of the slide rail from both the front and rear sides of the right slide rail of the sound insulation frame.

[0021] 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.

[0022] Please see Figure 1 - Figure 5 A soundproof protective cover for a heat pump unit includes a soundproof frame 1. The side projection shape of the soundproof frame 1 is U-shaped. The soundproof frame 1 serves as the main support structure and can be made of high-strength, corrosion-resistant metal materials such as steel plates, aluminum plates, or stainless steel plates, so that it has basic soundproofing function and is suitable for outdoor environments.

[0023] Furthermore, a left soundproof panel 2 and a right soundproof panel 3 are slidably installed between the upper and lower side walls of the soundproof frame 1 along its length. The left soundproof panel 2 and the right soundproof panel 3 are located on the left and right sides of the soundproof frame 1, respectively. A front protective door 4 is hinged to the left soundproof panel 2 and is located on the front side of the soundproof frame 1. A rear protective door 5 is hinged to the right soundproof panel 3 and is located on the rear side of the soundproof frame 1. The soundproof frame 1, the left soundproof panel 2, the right soundproof panel 3, the front protective door 4, and the rear protective door 5 cooperate to form a rectangular enclosure structure to enclose the heat pump unit. This allows the soundproof enclosure to provide sound insulation while also allowing the side walls to be opened, enabling maintenance personnel to open the side wall closest to the maintenance area or to open all the side walls of the enclosure, thus making the maintenance process more convenient.

[0024] In this embodiment, two slide rails 101 are fixedly provided on the upper and lower inner sidewalls of the sound insulation frame 1. The slide rails 101 are distributed along the length of the sound insulation frame 1. The two slide rails 101 located on the same sidewall of the sound insulation frame 1 are symmetrically distributed from left to right. The slide rails 101 on the left and right sides are respectively used for sliding connection of the left sound insulation panel 2 and the right sound insulation panel 3. This allows the left sound insulation panel 2 and the right sound insulation panel 3 to slide stably on the corresponding slide rails 101, thereby opening or closing the side of the enclosure.

[0025] The upper and lower side walls of the sound insulation frame 1 are fixedly connected by several support plates. The support plates are also made of high-strength metal materials, and the number and thickness of the support plates can be changed according to the actual situation to improve the overall support effect of the sound insulation frame 1. For example, support plates are set at the four ends between the upper and lower side walls of the sound insulation frame 1, thereby providing a good connection between the upper and lower side walls of the sound insulation frame 1.

[0026] On the other hand, the top and bottom of the left soundproof panel 2 and the right soundproof panel 3 are fixedly connected to sliders. The sliders are slidably connected to the slide rails 101 along the length of the soundproof frame 1. The upper and lower side walls of the left soundproof panel 2 abut against the upper and lower slide rails 101 on the left side of the soundproof frame 1, respectively. The upper and lower side walls of the right soundproof panel 3 abut against the upper and lower slide rails 101 on the right side of the soundproof frame 1, respectively. The length of the left soundproof panel 2 and the length of the right soundproof panel 3 are both equal to the length of the soundproof frame 1, so that the left soundproof panel 2 and the right soundproof panel 3 can completely seal the side of the soundproof frame 1, achieving a good sound insulation effect.

[0027] Furthermore, the left soundproof panel 2 can slide out from the front and rear sides of the left slide rail 101 of the soundproof frame 1, and the right soundproof panel 3 can slide out from the front and rear sides of the right slide rail 101 of the soundproof frame 1. The groove on the slide rail 101 can be designed to have openings at both the front and rear, and the sliders on the left and right soundproof panels 2 and 3 can be designed to match the shape of the groove, allowing the sliders to slide out from the groove. This allows the left and right soundproof panels 2 and 3 to be removed from the slide rail 101 for easy replacement and maintenance. This connection method needs to ensure that there is a large frictional resistance between the slider and the groove to make the left and right soundproof panels 2 and 3 more stable when sliding. Alternatively, the left and right soundproof panels 2 and 3 can be designed to be non-separable from the slide rail 101, making the enclosure more robust.

[0028] It should be noted that both the left soundproof panel 2 and the right soundproof panel 3 are U-shaped, with their openings facing each other. Sound-absorbing panels 6 are slidably installed on the inner sides of both the left and right soundproof panels 2 and 3 along the length of the soundproof frame 1. The sound-absorbing panels 6 can slide and embed into the inner side of the soundproof frame 1, and the length of the sound-absorbing panels 6 is equal to the length of the left soundproof panel 2, so that the sound-absorbing panels 6 can completely cover the inner sides of the left and right soundproof panels 2 and 3, further improving the sound insulation effect.

[0029] Among them, the left sound insulation panel 2 and the right sound insulation panel 3 are perforated metal sound-absorbing panels, which provide sound insulation for the device while ensuring structural strength. The material of the sound-absorbing panel 6 can be selected according to the actual situation, such as polyester fiber sound-absorbing panel, glass fiber sound-absorbing cotton, wooden perforated sound-absorbing panel, or ceramic aluminum decorative sound-absorbing panel, etc., which have the characteristics of sound absorption, environmental protection, and durability, and can extend the service life.

[0030] Furthermore, hinges are provided on the hinges connecting the left soundproof panel 2 and the front protective door 4, and on the hinges connecting the right soundproof panel 3 and the rear protective door 5. These hinges are vertically distributed so that the front protective door 4 can rotate around the hinges toward the outer side of the left soundproof panel 2, and the rear protective door 5 can rotate around the hinges toward the outer side of the right soundproof panel 3. When the front protective door 4 rotates at least 90° around the hinges, the sound-absorbing panel 6 on the left soundproof panel 2 can slide outwards from the outside of the left soundproof panel 2; when the rear protective door 5 rotates at least 90° around the hinges, the sound-absorbing panel 6 on the right soundproof panel 3 can slide outwards from the outside of the right soundproof panel 3. When the front protective door 4 rotates at least 90° around the hinge axis towards the outer side of the left sound insulation panel 2, the front protective door 4 will not obstruct the sliding of the sound-absorbing panel 6, allowing the sound-absorbing panel 6 to be removed from the left sound insulation panel 2; when the rear protective door 5 rotates at least 90° around the hinge axis towards the outer side of the right sound insulation panel 3, the rear protective door 5 will not obstruct the sliding of the sound-absorbing panel 6, allowing the sound-absorbing panel 6 to be removed from the right sound insulation panel 3, so that the user can regularly maintain and replace the sound-absorbing panel 6.

[0031] It should be noted that the side of the front protective door 4 away from the left soundproof panel 2 and the side of the right soundproof panel 3 away from the rear protective door 5 are detachably connected, as are the sides of the rear protective door 5 away from the right soundproof panel 3 and the left soundproof panel 2 away from the front protective door 4. For example, the front protective door 4 and the right soundproof panel 3, and the rear protective door 5 and the left soundproof panel 2 can be connected magnetically, or by using locks. Refer to existing cabinet doors, box doors, etc., to ensure the stability of the connection between the front protective door 4 and the right soundproof panel 3, and the rear protective door 5 and the left soundproof panel 2.

[0032] Several ventilation openings are provided on the front protective door 4 and the rear protective door 5 to balance the sound insulation and heat dissipation effects, and to prevent the heat generated by the heat pump unit from not being able to dissipate when the enclosure is completely sealed.

[0033] The working principle and usage process of this utility model are as follows: First, during installation, the left sound insulation panel 2 and the right sound insulation panel 3 are slidably embedded into the slide rails 101 on the left and right sides of the sound insulation frame 1, respectively. Then, the sound-absorbing panel 6 is slidably embedded into the inner side of the left sound insulation panel 2 and the right sound insulation panel 3 in the same way. Then, the front protective door 4 and the rear protective door 5 are flipped to the front and rear sides of the sound insulation frame 1, respectively. The left sound insulation panel 2, the right sound insulation panel 3, the front protective door 4 and the rear protective door 5 are fixed on the sound insulation frame 1 using locks or magnetic buckles, thus realizing the installation of the protective cover.

[0034] When it is necessary to maintain the internal heat pump unit, the front protective door 4 or the rear protective door 5 can be opened first to observe the area where the faulty component is located. Then, the left sound insulation panel 2 or the right sound insulation panel 3 can be slid to open the side wall closest to the faulty area, which will facilitate the maintenance process.
