Description

Technical Field

[0001] This utility model relates to the field of noise reduction housing technology for air source heat pumps, specifically to a structural reinforcement device for noise reduction housings of air source heat pumps. Background Technology

[0002] Air source heat pump units are widely used in high-end buildings such as office buildings, commercial buildings, and hotels. They are favored because they can simultaneously provide cooling and heating, adjusting the number and operation of the units according to the building's heating or cooling needs. However, due to limited floor space, air source heat pumps often need to be placed near residential areas or office buildings. The compressor and fan generate noise, which is transmitted outside the air source heat pump through the ductwork or air inlet on its surface. Therefore, the noise generated by air source heat pumps cannot be ignored.

[0003] Existing noise reduction housings for air source heat pumps are custom-made soundproof covers directly for the machine. After being assembled with bolts or rivets, the custom-made soundproof covers are directly installed on the outside of the air source heat pump for noise reduction. However, in actual use, traditional soundproof covers are mostly integral welded or bolted structures, which are only suitable for a single unit. Expansion requires the customization of an entire cover, which is costly and time-consuming. Therefore, it is necessary to improve the structure of the noise reduction housing for air source heat pumps to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a noise reduction and shell structure reinforcement device for air source heat pumps to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an air source heat pump noise reduction shell structure reinforcement device, including a C-shaped sound insulation side cover, a spliced ​​sound insulation cover is provided on the right side of the C-shaped sound insulation side cover, an installation mechanism is provided between the C-shaped sound insulation side cover and the spliced ​​sound insulation cover, and a heat dissipation mechanism is provided on the front and back of the spliced ​​sound insulation cover;

[0006] The installation mechanism includes an installation plate, which is disposed between the C-shaped soundproof side cover and the spliced ​​soundproof cover. A trapezoidal block is fixedly installed at the bottom of the installation plate. The installation plate is installed to the C-shaped soundproof side cover and the spliced ​​soundproof cover by bolts and threads.

[0007] Preferably, the trapezoidal block and the bolt are provided in two sets, and the dovetail groove is provided at the corresponding position of the C-shaped sound insulation side cover and the spliced ​​sound insulation cover and the trapezoidal block, and the trapezoidal block and the dovetail groove are interference fit.

[0008] Preferably, an anti-slip pad is fixedly installed on the outside of the trapezoidal block, a concave anti-slip cover is fixedly installed inside the dovetail groove, and a sealing door is fixedly installed inside the chamfered soundproof side cover by a hinge.

[0009] Preferably, the heat dissipation mechanism includes heat dissipation fins, which are installed on the front and back of the sound insulation panel by bolts with two threads.

[0010] Preferably, the sound insulation board is composed of a galvanized outer layer, a middle heat-conducting layer, and an inner sound-absorbing layer.

[0011] Preferably, the sound insulation board is composed of a galvanized outer layer, a middle thermally conductive layer, and an inner sound-absorbing layer from the outside to the inside. The surface of the galvanized outer layer is coated with a high emissivity coating, the middle thermally conductive layer is graphene-reinforced epoxy resin, and the inner sound-absorbing layer is a porous ceramic fiber board.

[0012] Preferably, the heat dissipation fins are provided in four sets and spliced ​​on the front of the sound insulation panel.

[0013] Compared with the prior art, this utility model provides a noise reduction and shell structure reinforcement device for air source heat pumps, which has the following beneficial effects:

[0014] 1. This air source heat pump noise reduction shell structure reinforcement device, during use, supports the series or parallel expansion of multiple units through the combination of modular splicing soundproof cover and dovetail trapezoidal blocks and bolts of the C-shaped soundproof side cover.

Workers only need to tighten the top bolt to complete the fixation.

[0015] 2. This air source heat pump noise reduction shell structure reinforcement device, during use, the inner sound-absorbing layer uses porous ceramic fiber to directly absorb heat pump noise, and the middle heat-conducting layer quickly transfers heat to the galvanized outer layer and heat dissipation fins, avoiding material aging and sound insulation performance degradation caused by local high temperature. Damaged heat dissipation fins or shell modules can be replaced by removing bolt one and bolt two, without the need for overall disassembly. Attached Figure Description

Detailed Implementation

[0022] 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.

[0023] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0024] Example 1:

[0025] Please see Figure 1-3 This utility model provides a technical solution: an air source heat pump noise reduction shell structure reinforcement device, including a C-shaped sound insulation side cover 1, a spliced ​​sound insulation cover 4 is provided on the right side of the C-shaped sound insulation side cover 1, an installation mechanism 2 is provided between the C-shaped sound insulation side cover 1 and the spliced ​​sound insulation cover 4, and a heat dissipation mechanism 3 is provided on the front and back of the spliced ​​sound insulation cover 4.

[0026] The mounting mechanism 2 includes a mounting plate 21, which is positioned between the dovetail soundproof side cover 1 and the spliced ​​soundproof cover 4. A trapezoidal block 22 is fixedly mounted on the bottom of the mounting plate 21. The mounting plate 21 is threadedly installed with the dovetail soundproof side cover 1 and the spliced ​​soundproof cover 4 by bolts 23. Through the combination of the modular spliced ​​soundproof cover 4 with the dovetail trapezoidal block 22 and bolts 23 of the dovetail soundproof side cover 1, it supports the series or parallel expansion of multiple units.

[0027] Furthermore, two sets of trapezoidal blocks 22 and bolts 23 are provided. Dovetail grooves are provided at the corresponding positions of the chamfered soundproof side cover 1 and the spliced ​​soundproof cover 4 and the trapezoidal block 22. The trapezoidal block 22 and the dovetail groove are interference fit. The initial positioning is achieved by using the self-locking structure of the trapezoidal block 22 and the dovetail groove. The worker only needs to tighten the top bolts 23 to complete the fixation, making the installation more convenient.

[0028] Furthermore, the trapezoidal block 22 is fixedly installed with an anti-slip pad on the outside, and the dovetail groove is fixedly installed with a concave anti-slip cover inside. The convex soundproof side cover 1 is fixedly installed with a sealing door through a hinge inside. If the bolt 23 becomes loose, the soundproofing operation can still be carried out by relying on the anti-slip pad and the concave anti-slip cover.

[0029] Example 2:

[0030] Please see Figure 4 Furthermore, in conjunction with Embodiment 1, it is further found that the heat dissipation mechanism 3 includes heat dissipation fins 34, which are threadedly installed on the front and back of the sound insulation plate 5 by bolts 35, so as to avoid material aging and sound insulation performance degradation caused by local high temperature.

[0031] Furthermore, the sound insulation panel 5 is composed of a galvanized outer layer 31, a middle heat-conducting layer 33, and an inner sound-absorbing layer 32.

[0032] Furthermore, the sound insulation panel 5 is composed of a galvanized outer layer 31, a middle heat-conducting layer 33, and an inner sound-absorbing layer 32 from the outside to the inside. The surface of the galvanized outer layer 31 is coated with a high emissivity coating, the middle heat-conducting layer 33 is graphene-reinforced epoxy resin, and the inner sound-absorbing layer 32 is a porous ceramic fiber board. The inner sound-absorbing layer 32 uses porous ceramic fiber to directly absorb heat pump noise, and the middle heat-conducting layer 33 quickly transfers heat to the galvanized outer layer 31 and the heat dissipation fins 34, thereby increasing heat dissipation and sound insulation effects.

[0033] Furthermore, four sets of heat dissipation fins 34 are provided and spliced ​​on the front of the sound insulation plate 5. Damaged heat dissipation fins 34 can be replaced by removing bolts 2 35 without the need for complete disassembly.

[0034] In actual operation, the C-shaped soundproof side cover 1 is installed on the top of the floor outside the location of the air source heat pump using expansion bolts. The spliced ​​soundproof cover 4 is placed on the right side of the C-shaped soundproof side cover 1. The trapezoidal block 22 is inserted into the dovetail grooves corresponding to the C-shaped soundproof side cover 1 and the spliced ​​soundproof cover 4. The mounting plate 21 is installed on the top of the C-shaped soundproof side cover 1 and the spliced ​​soundproof cover 4 using bolts 23. The splicing operation of the C-shaped soundproof side cover 1 and the spliced ​​soundproof cover 4 is completed. The splicing operation of the spliced ​​soundproof cover 4 can be continued according to the number of units in operation. After that, the C-shaped soundproof side cover 1 is installed on the other side of the spliced ​​soundproof cover 4 to complete the installation of the overall soundproofing device.

[0035] When noise occurs during the operation of the internal unit, it first passes through the inner sound-absorbing layer 32, which directly contacts the high-temperature area of ​​the heat pump to absorb the noise and conduct heat initially. The heat is then transferred from the inner sound-absorbing layer 32 to the galvanized outer layer 31 and the heat dissipation fins 34 through the intermediate heat-conducting layer 33, thereby completing the heat dissipation and noise reduction operation. If the heat dissipation fins 34 are damaged, or if the inverted sound insulation side cover 1 and the spliced ​​sound insulation cover 4 are damaged, the corresponding bolts 23 and 35 can be removed and replaced.

[0036] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.
