Description

Technical Field

[0001] This application relates to the field of generator set technology, and in particular to a high-efficiency heat dissipation and low-noise single-unit gas generator set soundproof enclosure. Background Technology

[0002] A gas generator set is a device that uses the combustion of gas to generate energy and then converts that energy into electrical energy. A gas generator set typically includes a gas engine, a generator, a radiator, and a control system. A single-unit gas generator set refers to a power generation device consisting of only one gas engine and a generator.

[0003] While gas-fired generator sets provide convenience, the noise they generate affects people's health, work, and daily life. Currently, when a generator set is operating at 75% load at a distance of 1 meter from most soundproof enclosures, the noise level is typically above 75 decibels. With the implementation of the "14th Five-Year Plan" for noise pollution prevention and control, higher noise reduction requirements have been placed on the gas-fired power generation industry. Utility Model Content

[0004] To facilitate achieving a noise reduction to 75 dB(A) when the generator set is operating at 75% load at a distance of 1 m from the enclosure, thus meeting the higher noise reduction requirements of the gas-fired power generation industry, this application provides a high-efficiency heat dissipation and low-noise single-unit gas generator set soundproof enclosure.

[0005] The silent enclosure for a single-unit gas generator set with high efficiency in heat dissipation and low noise provided in this application adopts the following technical solution:

[0006] A high-efficiency, low-noise, single-unit gas generator set soundproof enclosure includes a housing. The housing is used to house the gas generator and a cooling water tank. The housing has a door, and both the housing and the door have air inlet and outlet windows. Each air inlet and outlet window is equipped with a louver. Both the housing and the door have a hood, and the hood corresponds to each louver. The hood is located inside the corresponding louver, and the side of the hood away from the corresponding louver is covered with a first sound-absorbing layer that allows air to pass through.

[0007] Preferably, the inner wall of the enclosure is provided with a second sound-absorbing layer, the thickness of which is greater than or equal to 40mm.

[0008] Preferably, the housing is provided with a partition wall that divides the housing into a generator compartment and a cooling compartment. The generator compartment is used to house a gas generator, and the cooling compartment is used to house a radiator. The housing has multiple air inlet and outlet windows, which are respectively distributed in the generator compartment and the cooling compartment.

[0009] Preferably, the generator compartment and the cooling compartment are arranged parallel to the length direction of the housing, and the doors are arranged opposite each other along the length direction of the housing.

[0010] Preferably, an exhaust fan is installed in the shroud located inside the generator compartment on the housing.

[0011] Preferably, a wall-mounted control cabinet is installed inside the generator compartment, and the wall-mounted control cabinet is distributed opposite to the exhaust fan.

[0012] Preferably, the generator compartment is provided with maintenance doors on both opposite sides, and the arrangement direction of the maintenance doors on both sides is perpendicular to the arrangement direction of the generator compartment and the cooling compartment.

[0013] Preferably, the cooling chamber has an opening at the top, and the box body is provided with a fixed net to cover the opening.

[0014] Preferably, the side of the hood closest to the corresponding louver is provided with an insect-proof net.

[0015] Preferably, a sealing strip is provided on the side of the door near the box body, and the sealing strip is used to abut against the box body.

[0016] In summary, this application includes the following beneficial technical effects:

[0017] Since the first sound-absorbing layer covers the side of the shroud closest to the inside of the housing, when the generator set is working, the first sound-absorbing layer helps to block noise from being transmitted through the louvers, thereby improving the noise reduction effect. This makes it easier to achieve a noise reduction of 75dB(A) when the generator set is running at 75% load at a distance of 1m from the housing, which helps to meet the higher noise reduction requirements of the gas-fired power generation industry.

[0023] The following combination Figures 1-4 This application will be described in further detail.

[0024] This application discloses a high-efficiency heat dissipation and low-noise silent enclosure for a single-unit gas generator set. (Refer to...) Figure 1 and Figure 2 The high-efficiency heat dissipation and low-noise single-unit gas generator set soundproof enclosure includes a housing 1. The housing 1 is used to house the gas generator and the cooling water tank. The gas generator set of this application is a single-unit gas generator set, therefore, only one gas generator is provided. Specifically, the housing 1 includes a base 101, wall panels 102, and a top cover 103. The base 101 has a rectangular cross-section, and bolt holes are provided around the base 101. The wall panels 102 are fixedly installed around the base 101 by bolts, and the top cover 103 is fixed to the upper end of the wall panels 102. Thus, the base 101, the surrounding wall panels 102, and the top cover 103 form a space for housing the gas generator and the cooling water tank.

[0025] Reference Figure 1 and Figure 2 A door 2 is hinged to the wall panel 102 of the enclosure 1. The door 2 has a fixed lock for locking or opening the wall panel 102. The fixed lock is existing technology and will not be described in detail here. Both the wall panel 102 and the door 2 have air inlet and outlet windows 3. The size and number of air inlet and outlet windows 3 on the wall panel 102 and the door 2 can be set as needed and are not limited here.

[0026] Reference Figure 1 and Figure 3 Each air inlet / outlet window 3 is fixedly equipped with a louver 4. The louvers of the louver 4 are all in an inclined state, which helps to dissipate heat from the inside of the box 1. The wall panel 102 and the box door 2 are both fixedly equipped with a fan cover 5 by bolts. The fan cover 5 corresponds one-to-one with the air inlet / outlet window 3. The fan cover 5 covers the inside of the corresponding air inlet / outlet window 3. The side of the fan cover 5 away from the corresponding air inlet / outlet window 3 is covered with a first sound-absorbing layer 6 that can be ventilated. Specifically, the first sound-absorbing layer 6 is made of sound-absorbing cotton. In other embodiments, the first sound-absorbing layer 6 can also be made of mineral wool.

[0027] Because the first sound-absorbing layer 6 covers the shroud 5, when the generator set is operating, the air entering and exiting through the louvers 4 must pass through the corresponding first sound-absorbing layer 6. This first sound-absorbing layer 6 prevents the noise generated by the generator set from easily propagating through the louvers 4, improving noise reduction. This facilitates achieving a noise level of 75 dB(A) when the generator set is operating at 75% load at a distance of 1m from the housing 1, helping to meet the higher noise reduction requirements of the gas-fired power generation industry. Here, 75 dB(A) represents a noise level of 75 decibels, and has been processed using an A-weighted network.

[0028] Reference Figure 2 The inner walls of the wall panels 102 and the top cover 103 of the enclosure 1 are both covered with a second sound-absorbing layer (not shown in the figure). The thickness of the second sound-absorbing layer is greater than or equal to 40 mm. In this embodiment, the second sound-absorbing layer is sound-absorbing cotton. In other embodiments, the second sound-absorbing layer can also be mineral wool, sound-insulating foam, etc. By setting the second sound-absorbing layer, the propagation of noise is reduced, further improving the quietness of the enclosure 1, and helping to reduce the noise level to 75 dB(A) when the generator set is running at 75% load at a distance of 1 m from the enclosure 1.

[0029] Reference Figure 2 and Figure 3 An insect-proof net 15 is fixedly connected to the side of the fan cover 5 near the corresponding louver 4. The insect-proof net 15 is designed between the fan cover 5 and the corresponding louver 4, so that external insects and ants are not easy to enter the box 1, ensuring the normal operation of the equipment in the box 1.

[0030] Reference Figure 2 and Figure 4 A partition wall 7 is fixedly installed inside the housing 1. Specifically, the partition wall 7 is fixedly connected to the base 101, wall panel 102, and top cover 103, respectively. The partition wall 7 divides the housing 1 into a generator compartment 8 and a cooling compartment 9. The arrangement direction of the generator compartment 8 and the cooling compartment 9 is parallel to the length direction of the housing 1. The cross-sectional area of ​​the generator compartment 8 is larger than that of the cooling compartment 9. The generator compartment 8 is used to house the gas generator. A shelf 16 is fixedly installed inside the cooling compartment 9, and a radiator is placed on the shelf 16. The pipes connecting the radiator and the gas generator are fixedly installed through the partition wall 7, so that the installation of the partition wall 7 does not affect the connection between the two. Since the noise generated by the generator set mainly comes from the operation of the generator itself, the installation of the partition wall 7 prevents the radiant heat of the generator compartment 8 from causing an increase in the intake air temperature of the cooling compartment 9, which helps to reduce the operating load of the fan built into the radiator and effectively ensures that the generator set can operate stably for a long time.

[0031] Reference Figure 2 and Figure 4Multiple air inlet and outlet windows 3 are provided on the wall panel 102 of the housing 1. These multiple air inlet and outlet windows 3 are distributed on the wall panel 102 of the generator compartment 8 and the wall panel 102 of the cooling compartment 9. Specifically, the air inlet and outlet windows 3 on the wall panel 102 of the generator compartment 8 are all located on the same side of the wall panel 102 of the generator compartment 8; while the air inlet and outlet windows 3 on the wall panel 102 of the cooling compartment 9 are symmetrically located on opposite sides of the wall panel 102 of the cooling compartment 9. The size and number of air inlet and outlet windows 3 on the wall panel 102 of the generator compartment 8 and the wall panel 102 of the cooling compartment 9 are set as needed.

[0032] Reference Figure 2 and Figure 4 The enclosure doors 2 are arranged opposite each other along the length of the enclosure 1, so that the generator compartment 8 and the cooling compartment 9 are each equipped with an enclosure door 2 on the side away from each other; specifically, each of the generator compartment 8 and the cooling compartment 9 has two enclosure doors 2 to facilitate opening of the generator compartment 8 or the cooling compartment 9. To improve the sealing effect, noise reduction effect and waterproof performance of the enclosure doors 2, a sealing strip is adhered to the side of each enclosure door 2 closest to the enclosure 1. The sealing strip is used to abut against the corresponding wall panel 102. The sealing strip can be one of a rubber strip, a silicone strip or a plastic strip, and there is no limitation here. Specifically, the sealing strip can be arranged along the circumference of the enclosure door 2 or designed in a U-shape, and there is no limitation here.

[0033] Reference Figure 2 and Figure 3 An exhaust fan (not shown in the figure) is fixedly installed in the shroud 5 on the wall panel 102 of the generator compartment 8 by bolts. The exhaust fan helps to exhaust the radiant heat of various equipment in the generator compartment 8 to the outside, thereby improving the heat dissipation effect of the generator set during operation.

[0034] Reference Figure 2 A wall-mounted control cabinet 11 is fixedly installed inside the generator compartment 8. The wall-mounted control cabinet 11 is distributed opposite to the exhaust fan. That is, the control cabinet 11 is fixedly installed on the wall panel 102 on the opposite side of the exhaust fan in the generator compartment 8. The control cabinet 11 is installed separately as a complete wall-mounted unit in the generator compartment 8. On the one hand, it does not occupy the position of the base 101, and on the other hand, it does not take up extra time and space for the assembly of the unit.

[0035] Reference Figure 2 and Figure 4 To facilitate maintenance of the equipment inside the generator compartment 8, maintenance doors 12 are installed on the opposite side wall panels 102 of the generator compartment 8. The arrangement direction of the maintenance doors 12 is perpendicular to the arrangement direction of the generator compartment 8 and the cooling compartment 9. The maintenance doors 12 are located between the louvers 4 on the generator compartment 8 and the louvers 4 on the cooling compartment 9. Specifically, the maintenance doors 12 can be equipped with louvers 4 of the same structure as those on the cabinet door 2, which helps to further improve the heat dissipation effect inside the generator compartment 8.

[0036] Reference Figure 2 and Figure 4 An opening 13 is provided on the top cover 103 of the cooling chamber 9. A fixing mesh 14, made of steel wire mesh, is bolted to the top cover 103 to cover the opening 13. Since the largest source of noise during generator operation is generated by the generator itself, installing a steel wire mesh on the top cover 103 of the cooling chamber 9 can greatly improve the heat dissipation effect inside the cooling chamber 9 without causing noise transmission.

[0037] The implementation principle of this application embodiment is as follows: When the gas generator set is working, the air entering and exiting through the louvers 4 will inevitably pass through the first sound-absorbing layer 6 on the hood 5. The first sound-absorbing layer 6 can make it difficult for the noise generated by the gas generator set to be transmitted from the louvers 4. At the same time, the second sound-absorbing layer covering the inner wall of the wall panel 102 and the top cover 103 further reduces the propagation of noise, making it easier to reduce the noise to 75 decibels when the generator set is running at 75% load at a distance of 1m from the housing 1, which helps to meet the higher noise reduction requirements of the gas power generation industry.

[0038] By dividing the housing 1 into a generator compartment 8 and a cooling compartment 9, the radiant heat from the generator compartment 8 will not raise the intake air temperature in the cooling compartment 9, which helps to reduce the operating load of the built-in fan on the radiator and achieves good heat dissipation.

[0039] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
