A housing structure for an evaporator

Abstract

This utility model belongs to the field of ventilator technology, and in particular to a ventilator housing structure, including a body with a shell on the body. Two transformers are housed inside the shell, and two transformer-to-transformer heat dissipation assemblies corresponding to the transformers are provided on the shell. Each transformer-to-transformer heat dissipation assembly includes a filter screen, a voltage-stabilizing heat dissipation plate, and a pressure pad. The pressure pad is fixed to one side of the voltage-stabilizing heat dissipation plate and attached to the outer surface of the transformer. By attaching the pressure pad to the outer surface of the transformer and covering the outside of the transformer with the voltage-stabilizing heat dissipation plate, the position of the transformer can be further stabilized after the shell is installed, and heat dissipation is facilitated. Simultaneously, by rotating the position of the filter screen, the filter screen and voltage-stabilizing heat dissipation plate can be pulled out from the shell, facilitating direct inspection of the transformer through the corresponding position on the shell. This not only ensures stable operation of the ventilator and reduces the vibration frequency of the transformer inside the ventilator, but also extends the service life of the ventilator.

Description

Technical Field

[0001] This utility model belongs to the field of ventilator technology, specifically relating to a ventilator housing structure. Background Technology

[0002] A phono amplifier amplifies a weak electrical signal from a signal source to drive a speaker to produce sound. It can also refer to other devices that amplify power. If a transformer is installed inside the phono amplifier, the problem of sound quality distortion can be solved.

[0003] Adding a transformer inside the ventilator can change the power consumption of the ventilator and improve its performance. The casing can protect the internal structure of the ventilator. However, it can reduce heat dissipation, increase the vibration frequency of the transformer inside the ventilator, and reduce the lifespan of the ventilator. Utility Model Content

[0004] This utility model provides a housing structure for an idler, which further stabilizes the position of the transformer after the housing is installed, facilitates heat dissipation, not only enables stable operation of the idler and reduces the vibration frequency of the transformer inside the idler, but also improves the service life of the idler.

[0005] This utility model provides the following technical solution: a housing structure for an idler, including a body, a shell on the body, two transformers inside the shell, and two transformer-to-transformer heat dissipation assemblies corresponding to the transformers on the shell. Each transformer-to-transformer heat dissipation assembly includes a filter screen, a voltage stabilizing heat dissipation plate, and a pressure pad. The pressure pad is fixed to one side of the voltage stabilizing heat dissipation plate and is attached to the outer surface of the transformer. A locking mounting rod is fixedly connected to the outside of the filter screen and is locked to the shell.

[0006] The housing has an annular mounting groove, and the engaging mounting rod is located within the annular mounting groove.

[0007] A locking seat is fixedly connected inside the annular mounting groove, and the locking mounting rod is locked inside the locking seat.

[0008] The annular mounting groove has an opening for the locking mounting rod to pass through, and the voltage stabilizing heat sink has a plurality of heat dissipation holes.

[0009] The filter screen is fixedly connected to a rotary operating knob on its outer side, and the filter screen is inserted into the housing.

[0010] The voltage stabilizing heat sink has two transition grooves, and the pressure pad is located at the center of the transformer.

[0011] The beneficial effects of this utility model are:

[0012] The transformer is installed inside the housing using a transformer-specific heat dissipation assembly, including a filter, a voltage regulator heat sink, and pressure pads. The pressure pads are attached to the outer surface of the transformer, and the voltage regulator heat sink covers the outside of the transformer. This design further stabilizes the transformer's position after the housing is installed and facilitates heat dissipation. By rotating the filter, both the filter and the voltage regulator heat sink can be removed from the housing, allowing for direct inspection of the transformer through corresponding positions on the housing. This not only ensures stable operation of the ignition system and reduces the vibration frequency of the transformer inside the ignition system, but also extends the service life of the ignition system.

[0020] Please see Figures 1-5 The present invention provides the following technical solution: it includes a body 1, a housing 11 on the body 1, two transformers 12 inside the housing 11, and two transformer-relative heat dissipation assemblies 2 corresponding to the transformers 12 on the housing 11. The transformer-relative heat dissipation assembly 2 includes a filter screen 21, a voltage stabilizing heat dissipation plate 22 and a pressure pad 24. The pressure pad 24 is fixed on one side of the voltage stabilizing heat dissipation plate 22 and is attached to the outer surface of the transformer 12. A locking mounting rod 25 is fixedly connected to the outside of the filter screen 21 and is locked to the housing 11.

[0021] In this implementation scheme: Two transformers 12 are installed inside the housing 11. The transformers 12 can be connected to the main body 1 for use, improving the performance of the venting unit. The transformer-to-heat dissipation assembly 2 includes a filter screen 21, a voltage stabilizing heat sink 22, and a pressure pad 24. The filter screen 21 is located on the outside of the housing 11, protecting the voltage stabilizing heat sink 22. The pressure pad 24 is fixed to one side of the voltage stabilizing heat sink 22 and is attached to the outer surface of the transformer 12. A locking mounting rod 25 is fixedly connected to the outside of the filter screen 21, and the locking mounting rod 25 is engaged with the housing 11. The transformer 12 is installed inside the housing 11, and the pressure pad 24 is attached to the outer surface of the transformer 12. The voltage stabilizing heat sink 22 covers the outside of the transformer 12. This allows for further stabilization of the transformer 12 after installation in the housing 11 and facilitates heat dissipation. At the same time, rotating the filter screen 21 engages the locking mounting rod. The rod 25 can rotate within the annular mounting groove 111 and move out of the locking seat 112, allowing the filter screen 21 and the voltage regulator heat sink 22 to be pulled out of the housing 11. The annular mounting groove 111 has an opening for the locking rod 25 to pass through. The locking rod 25 can move outward along the opening, facilitating direct inspection of the transformer 12 through the corresponding position on the housing 11. This not only ensures stable operation of the ventilator and reduces the vibration frequency of the transformer 12 inside the ventilator, but also extends the service life of the ventilator. During installation, the filter screen 21 and the voltage regulator heat sink 22 are inserted into the housing 11, and the locking rod 25 rotates within the annular mounting groove 111. The locking seat 112 is made of plastic and can be used to lock the locking rod 25 into the locking seat 112, thus fixing the position of the voltage regulator heat sink 22 and stabilizing the internal structure of the housing 11.

[0022] The housing 11 has an annular mounting groove 111, and the engaging mounting rod 25 is located in the annular mounting groove 111; the engaging mounting rod 25 can rotate in the annular mounting groove 111 to remove the filter screen 21 from the housing 11, or to install it on the housing 11.

[0023] A locking seat 112 is fixedly connected inside the annular mounting groove 111, and the locking mounting rod 25 is locked inside the locking seat 112. The locking mounting rod 25 rotates inside the annular mounting groove 111. The locking seat 112 is made of plastic and can be locked into the locking seat 112 by means of elasticity, which can fix the position of the voltage stabilizing heat sink 22 and make the housing 11 stably restrict the internal structure of the machine body 1.

[0024] The annular mounting groove 111 has an opening for the locking mounting rod 25 to pass through, and the voltage stabilizing heat sink 22 has several heat dissipation holes 221; the filter screen 21 and the voltage stabilizing heat sink 22 can be pulled out from the housing 11. The annular mounting groove 111 has an opening for the locking mounting rod 25 to pass through, and the locking mounting rod 25 can move outward along the position of the opening, which facilitates direct inspection of the transformer 12 through the corresponding position on the housing 11.

[0025] A rotary operating knob 23 is fixedly connected to the outside of the filter screen 21, and the filter screen 21 is inserted into the housing 11. The rotary operating knob 23 can facilitate the operation of the filter screen 21. The filter screen 21 is flush with the end face of the housing 11, which can help limit the position of the filter screen 21.

[0026] The voltage regulator heat sink 22 has two transition grooves 222, and the pressure pad 24 is located at the center of the transformer 12. The transition grooves 222 facilitate the operation of the voltage regulator heat sink 22, allowing the voltage regulator heat sink 22 to be pulled out from the housing 11. The pressure pad 24 is used to attach it to the outer surface of the transformer 12. The voltage regulator heat sink 22 covers the outside of the transformer 12, and the position of the transformer 12 can be further stabilized directly after the housing 11 is installed.

[0027] The working principle and usage process of this utility model: The transformer 12 can be connected to the body 1 to improve the performance of the refrigeration unit. The transformer-to-heat dissipation assembly 2 includes a filter 21, a voltage stabilizing heat sink 22, and a pressure pad 24. The filter 21 is located on the outside of the housing 11, protecting the voltage stabilizing heat sink 22. The pressure pad 24 is fixed to one side of the voltage stabilizing heat sink 22 and is attached to the outer surface of the transformer 12. A locking mounting rod 25 is fixedly connected to the outside of the filter 21 and engages with the housing 11. The transformer 12 is installed inside the housing 11, and the pressure pad 24 is attached to the outer surface of the transformer 12. The voltage stabilizing heat sink 22 covers the outside of the transformer 12. This further stabilizes the position of the transformer 12 after installation in the housing 11 and facilitates heat dissipation. At the same time, rotating the filter 21 allows the locking mounting rod 25 to engage. The filter 21 and the voltage regulator heat sink 22 can be pulled out of the housing 11 by rotating within the annular mounting groove 111 and moving out of the locking seat 112. The annular mounting groove 111 has an opening for the locking mounting rod 25 to pass through. The locking mounting rod 25 can move outward along the opening, making it easy to directly inspect the transformer 12 through the corresponding position on the housing 11. This not only ensures stable operation of the ventilator and reduces the vibration frequency of the transformer 12 inside the ventilator, but also extends the service life of the ventilator. During installation, the filter 21 and the voltage regulator heat sink 22 are inserted into the housing 11, and the locking mounting rod 25 rotates within the annular mounting groove 111. The locking seat 112 is made of plastic and can be used to lock the locking mounting rod 25 into the locking seat 112 by elasticity, thus fixing the position of the voltage regulator heat sink 22 and making the housing 11 stably restrict the internal structure of the body 1.
