Description

Technical Field

[0001] The utility model relates to the technical field of explosion-proof frequency converter chassis, in particular to a heat absorption and heat dissipation balanced explosion-proof frequency converter chassis. Background Art

[0002] An explosion-proof inverter utilizes frequency conversion and microelectronics technology to control the power transmission of an AC motor by varying the frequency and amplitude of the motor's operating power supply. It is primarily used in environments with explosive gases or high dust content, such as coal mines and oil fields, to ensure safe operation. Its primary functions include voltage and current protection, automatically shutting down the motor when voltage or current is abnormal, protecting the motor from damage. Existing explosion-proof inverter components are typically fixed inside the inverter chassis.

[0003] The heat generated by the explosion-proof inverter in the prior art when working in the chassis is difficult to be discharged from the chassis. After working for a long time, the internal temperature of the chassis increases, which can easily cause the electrical components of the inverter to malfunction or even be damaged.

[0007] Furthermore, the refrigeration assembly includes an evaporator fixed to the inner wall of the chassis body, a condenser connected to a water pump, and a compressor connected to both the condenser and the evaporator. The evaporator is connected to the water tank through a pipeline.

[0008] By adopting the above technical solution, the water in the water tank is quickly cooled down through the coordinated use of the condenser, evaporator and compressor. The fan blows the cold air generated by the evaporator toward the mounting plate and the explosion-proof inverter and discharges it from the heat dissipation holes, which is conducive to the rapid heat dissipation of the explosion-proof inverter.

[0009] Furthermore, a filter for filtering dust is provided on the top of the chassis body.

[0010] By adopting the above technical solution, the setting of the filter screen plays a filtering and protective role on the heat dissipation holes, reducing the probability of external dust entering the chassis body through the heat dissipation holes.

[0011] Furthermore, a stepped groove is provided on the top of the chassis body, a filter frame is provided in the stepped groove and is plugged into the stepped groove, and the filter is fixed in the filter frame.

[0015] Furthermore, a protective cover for covering the condenser and the evaporator is provided on the upper surface of the water tank.

[0018] By adopting the above technical solution, the heat dissipation fan provides a heat dissipation effect for the condenser, so that the heat generated by the condenser is discharged outside the protective cover, which is conducive to rapid cooling of the water.

[0019] Furthermore, a heat absorbing plate is provided on the inner wall of the chassis body, and heat dissipation fins are fixed on the outer wall of the chassis body.

[0020] By adopting the above technical solution, the heat absorbing plate and the heat dissipating fins have good thermal conductivity, can quickly absorb and dissipate the heat inside the chassis body, and improve the heat dissipation effect of the chassis body.

DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application; it is obvious that the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0030] like Figure 1-3 As shown, an embodiment of the present application discloses a heat absorption and heat dissipation balanced explosion-proof inverter chassis, including a chassis body 1, a mounting plate 2, a water tank 3, a water pump 4, a refrigeration component 5 and a fan 6.

[0031] The chassis body 1 is a rectangular parallelepiped structure, with multiple cooling holes 101 extending through the top. The mounting plate 2 is a rectangular plate-like structure fixed to the inner wall of the chassis body 1, with multiple cooling holes 21 extending through its top surface. The water tank 3 is a rectangular parallelepiped structure, fixed to the side wall of the chassis body 1. The water pump 4 is a commonly used pump in the prior art and suitable for this embodiment, and is mounted on the side wall of the water tank 3.

[0032] The refrigeration assembly 5 is mounted on the water tank 3 and within the chassis body 1 for cooling. The refrigeration assembly 5 includes an evaporator 51, a condenser 52, and a compressor 53. The evaporator 51 is a commonly used evaporator 51 in the prior art and applicable to this embodiment. The evaporator 51 is fixed to the inner wall of the chassis body 1 and is connected to the water tank 3 via a pipeline. The condenser 52 is a commonly used condenser 52 in the prior art and applicable to this embodiment. The condenser 52 is connected to the water pump 4 via a pipeline. The compressor 53 is a commonly used compressor 53 in the prior art and applicable to this embodiment. The compressor 53 is connected to the condenser 52 and the evaporator 51 via pipelines.

[0033] The water pump 4 pumps the water in the water tank 3 into the refrigeration assembly 5 and circulates it. Through the coordinated use of the condenser 52, the evaporator 51 and the compressor 53, the water in the water tank 3 is quickly cooled. The fan 6 is started to blow the cold air generated by the evaporator 51 to the mounting plate 2, and cools the explosion-proof inverter and the inside of the chassis body 1 through the cold air holes 21 on the mounting plate 2. The heat is discharged through the heat dissipation holes 101, reducing the probability that the electrical components of the inverter cannot work normally or even are damaged due to the high temperature inside the chassis body 1.

[0034] In order to protect the heat dissipation holes 101, a filter screen 7 for filtering dust is provided on the top of the chassis body 1. The setting of the filter screen 7 plays a filtering and protective role for the heat dissipation holes 101, reducing the probability of external dust entering the chassis body 1 through the heat dissipation holes 101.

[0035] In order to facilitate the disassembly and cleaning of the filter, a stepped groove 102 is provided on the top of the chassis body 1, and a filter frame 8 is provided in the stepped groove 102, which is plugged into the stepped groove 102. The filter 7 is fixed in the filter frame 8, and the filter frame 8 is plugged into the stepped groove 102, so that the filter can be detachably connected to the chassis body 1, thereby facilitating the disassembly and cleaning of the filter.

[0036] In order to facilitate the removal of the filter frame 8, a handle 81 is fixed on the upper surface of the filter frame 8. The setting of the handle 81 provides a fulcrum for the filter frame 8, thereby making it easy for the staff to remove the filter frame 8 from the stepped groove 102.

[0037] In order to protect the condenser 52 and the evaporator 51, a protective cover 9 for covering the condenser 52 and the evaporator 51 is provided on the upper surface of the water tank 3. The protective cover 9 protects the condenser 52 and the evaporator 51, reducing the probability of damage to the condenser 52 and the evaporator 51 under the action of external force.

[0038] In order to discharge the heat generated by the condenser 52, an installation opening 91 is opened through the side wall of the protective cover 9. The installation opening 91 is set at a position close to the condenser 52. A cooling fan 10 is fixed in the installation opening 91. The cooling fan 10 provides a heat dissipation effect for the condenser 52, so that the heat generated by the condenser 52 is discharged outside the protective cover 9, which is conducive to rapid cooling of the water.

[0039] In order to improve the heat dissipation effect of the chassis body 1, a heat absorbing plate 11 is provided on the inner wall of the chassis body 1, and heat dissipating fins 12 are fixed on the outer wall of the chassis body 1. The heat absorbing plate 11 and the heat dissipating fins 12 have good thermal conductivity and can quickly absorb and dissipate the heat inside the chassis body 1, thereby improving the heat dissipation effect of the chassis body 1.

[0040] The operating principle of a heat absorption and heat dissipation balanced explosion-proof inverter chassis in this embodiment is as follows: the water pump 4 pumps the water in the water tank 3 into the refrigeration assembly 5 and circulates it, and the water in the water tank 3 is quickly cooled by the coordinated use of the condenser 52, the evaporator 51 and the compressor 53. The fan 6 is started to blow the cold air generated by the evaporator 51 toward the mounting plate 2, and cools the explosion-proof inverter and the inside of the chassis body 1 through the cold air holes 21 on the mounting plate 2. The heat is discharged through the heat dissipation holes 101, reducing the probability that the inverter electrical components cannot work normally or even are damaged due to the high temperature inside the chassis body 1.

All technical solutions based on the concept of the present invention are within the scope of protection of the present invention. It should be noted that for those skilled in the art, certain improvements and modifications that do not depart from the principles of the present invention should also be considered within the scope of protection of the present invention.
