Description

Technical Field

[0001] The utility model belongs to the technical field of noise reduction devices, in particular to a noise reduction device for an air energy heat pump. Background Art

[0002] An air energy heat pump is a heat energy conversion device that uses air as a heat source and raises low-temperature heat energy to high-temperature heat energy through a compression cycle. An air energy heat pump will generate vibration noise and mechanical noise during use. In order to reduce noise pollution, it needs to be noise-reduced.

[0003] In a Chinese patent with publication number CN219976798U, a noise reduction structure of an air energy heat pump is mentioned. The utility model places the noise-generating air energy pump body into a groove, inserts the corresponding groove of the sound insulation cover into the groove, and squeezes the outer wall of the sound insulation cover through the sealing strip inside the groove to improve the installation stability of the sound insulation cover. At this time, one side of the sound insulation cover is open, which can facilitate the extension of the connecting pipe to the outside of the sound insulation cover to complete the relative connection between the delivery pump and the air energy heat pump body. Subsequently, the sliding strip on the outside of the closed door and the sliding groove on the inside of the connecting strip are slidably connected to each other, so that the closed door is slid downward to close the sound insulation cover, and the noise generated by the air energy pump body inside the sound insulation cover can be blocked. At the same time, the air energy pump body is connected through the delivery pump, so that the air energy pump body can be supplied with air heat source in time.

[0004] However, although the device is soundproofed by sealing the air energy heat pump inside the soundproof cover, it also makes it impossible to discharge the heat generated by the internal air energy heat pump during operation. The air energy heat pump needs to work in a certain ventilation environment to avoid the difficulty in dissipating the heat of the air energy heat pump, which makes the working environment temperature of the air energy heat pump high, causing damage to internal components and even system overload shutdown, and also causing the working efficiency of the air energy heat pump to decrease and the internal components to age and damage.

[0024] As attached Figure 1 To Attachment Figure 5 As shown:

[0025] Embodiment 1: The utility model provides a noise reduction device for an air energy heat pump, including a noise reduction mechanism 100, a sound insulation groove 101, a mounting groove 102 fixedly arranged inside the sound insulation groove 101, sound-absorbing cotton 103 fixedly installed on the inner surface of the sound insulation groove 101 and the outer surface of the mounting groove 102, a sound-absorbing cavity is formed between the sound insulation groove 101 and the mounting groove 102, and a sound insulation sealing plate 109 is installed on the upper end of the sound insulation groove 101 by a plurality of bolts.

[0026] The noise reduction mechanism 100 further includes two mounting slots 104 relatively opened on both sides of the mounting slot 102 , the two mounting slots 104 are both slidably connected with mounting plates 105 , and an air energy heat pump 106 is fixedly installed between the two mounting plates 105 .

The lower ends of the plurality of shock absorbers 108 are fixedly connected to the lower end of the interior of the installation slot 102 .

[0028] A plurality of connection holes 110 are provided on one side of the sound insulation sealing plate 109 .

[0029] Damping rubber rings 111 are disposed inside the plurality of connection holes 110 .

[0030] As can be seen from the above, when in use, first use the portable air energy heat pump 106 to align the mounting card plates 105 installed on both sides of the air energy heat pump 106 with the mounting card slots 104, and snap the mounting card plates 105 into the mounting card slots 104, so that the air energy heat pump 106 is installed inside the mounting slots 102, and the air energy heat pump 106 is in contact with the shock-absorbing pads 107. The shock-absorbing pads 107 provide support for the air energy heat pump 106, and the required pipes and electrical properties of the air energy heat pump 106 are installed through the connecting holes 110, and then the sound insulation sealing plate 109 is installed to seal the upper end of the sound insulation slot 101.

[0031] When the air energy heat pump 106 vibrates during operation, the vibration force is absorbed by the shock absorbing pad 107 and the shock absorber 108, thereby reducing the vibration transmission to the external pipeline or building to cause resonance noise, thereby effectively reducing the noise of the air energy heat pump 106.

[0032] The mechanical noise generated by the operation of the air energy heat pump 106 is first blocked by the installation groove 102, and part of the mechanical noise is transmitted to the sound insulation groove 101, and the noise is absorbed by the sound-absorbing cotton 103 to further reduce the noise. The sound insulation groove 101 and the sound insulation sealing plate 109 further block the noise, thereby effectively reducing the noise when the air energy heat pump 106 is working.

[0033] Embodiment 2: This is the second embodiment of the present utility model, comprising a heat reduction mechanism 200, which comprises a plurality of air holes 201 opened on both sides of the sound insulation groove 101 and on both sides of the sound insulation groove 101, a driving assembly is installed on the upper end of the sound insulation sealing plate 109, the driving assembly comprises a temperature sensor 202 fixedly installed on one side of the inner part of the installation groove 102, a guide groove 203 is fixedly installed on the upper end of the sound insulation sealing plate 109, a dispersion plate 204 is relatively slidably installed inside the guide groove 203, a sound insulation half box 205 is fixedly installed on one side of the two dispersion plates 204, and the two sound insulation half boxes 205 are both slidably connected to the sound insulation sealing plate 109.

[0034] The driving assembly also includes a threaded rod 206 rotatably installed inside the guide groove 203, and threaded rings are fixedly inserted into the two dispersion plates 204, and the two threaded rings are engaged with the threaded rod 206. A driving motor 207 is fixedly installed inside the sound insulation sealing plate 109, and a pulley 1 is fixedly installed on the output end of the driving motor 207 through a coupling, and a pulley 2 is fixedly installed on the front end of the threaded rod 206. Pulley 1 and pulley 2 are connected by a transmission belt 208, and a cooling fan 209 is fixedly connected to the upper end of the sound insulation sealing plate 109.

[0035] As can be seen from the above, by opening a plurality of air holes 201, the air absorption demand of the air energy heat pump 106 can be guaranteed, and by being able to dissipate the heat generated by the air energy heat pump 106 during operation, the air energy heat pump 106 can maintain operation in a certain ventilation environment. If the air energy heat pump 106 works for a long time and the heat accumulated inside the installation slot 102 is too much, after the temperature reaches the set temperature of the temperature sensor 202, the signal is transmitted to the central control system, and the central control system starts the drive motor 207 to rotate, and the transmission belt 208 drives the threaded rod 206 to rotate and engage with the threaded ring, thereby driving the two dispersion plates 204 to separate, and further separating the two sound insulation half boxes 205 to expose the heat dissipation fan 209, and starting the heat dissipation fan 209 to quickly dissipate heat and cool down the inside of the installation slot 102. When the temperature drops, When the temperature drops to the standard temperature, the central control system controls the driving motor 207 to reverse, close the sound insulation half box 205, and block and soundproof the larger through hole at the cooling fan 209, which can reduce the noise transmitted from the larger through hole to the air, reduce the propagation of noise, and when the air through hole 201 can meet the heat dissipation of the installation slot 102, that is, the temperature does not exceed the maximum setting value of the temperature sensor 202, the cooling fan 209 is turned off, which can further reduce the noise generated when the cooling fan 209 is working, thereby achieving effective noise reduction. In addition, when the temperature rises, the driving component can also effectively dissipate the heat inside the installation slot 102 in time, avoiding damage to the internal components of the air energy heat pump 106 due to excessive temperature, and even causing system overload shutdown, and avoiding excessive temperature causing the air energy heat pump 106 to reduce the working efficiency and aging and damage of internal components.
