[0036] As Figure 5As shown, the temperature monitoring assembly 9 comprises two groups of temperature monitoring elements 91 arranged in upper and lower positions, which are respectively installed at the upper end and the lower end inside the cabinet body 1. The temperature monitoring elements 91 are connected with an alarm 92, which is electrically connected with the refrigeration air conditioner 3.

[0037] In the embodiment, each group of temperature monitoring elements 91 comprises at least one temperature sensor, which is arranged at a position corresponding to the position of the electrical element inside the cabinet body 1.

[0038] In the embodiment, the electrical elements inside the cabinet body 1 are generally installed in two rows of upper and lower positions, and the two groups of temperature monitoring elements 91 and the cooling assembly 5 are respectively installed at the positions of the two rows of electrical elements.

[0039] In the embodiment, the alarm 92 can be a commercially available multi-threshold alarm.

[0040] In the embodiment, the two groups of temperature monitoring elements 91 are respectively connected with two alarms 92.

[0041] As shown in Figure 1 and Figure 3 As shown, the cooling assembly 5 comprises a plurality of horizontal pipes 51 arranged in sequence from top to bottom. The air inlet end of the horizontal pipe 51 extends into the air inlet box 2, the inner cavity of the horizontal pipe 51 is connected with the inner cavity of the air inlet box 2 through the opening of the air inlet end, the other end of the horizontal pipe 51 extends into the air outlet box 4, a plurality of cold air outlets 52 are arranged on the pipe wall of the horizontal pipe 51 in an interlaced manner, a rotating shaft 53 is rotatably installed inside the horizontal pipe 51, a plurality of sealing arc plates 54 for opening and closing the cold air outlets 52 are fixed on the rotating shaft 53, and the sealing arc plates 54 are arranged in one-to-one correspondence with the cold air outlets 52.

[0042] In the embodiment, the end of the horizontal pipe 51 extending into the air inlet box 2 is provided with an opening, so as to facilitate the low-temperature cold air to enter the horizontal pipe 51.

[0043] The end of the horizontal pipe 51 extending into the air outlet box 4 is sealingly arranged, so as to avoid the situation that the low-temperature cold air is directly discharged without playing a cooling role.

[0044] Since the number and arrangement position of the electrical elements on the upper and lower fixing frames of the cabinet body 1 will be different, the temperature of the electrical elements on the upper row and the lower row inside the cabinet body 1 can be greatly different.

[0045] In the embodiment, the two groups of cooling assemblies 5 are arranged, so as to realize the partition cooling and heat dissipation of the electrical elements on the upper row and the lower row, and the energy consumption of the electrical cabinet can be reduced under the premise of ensuring the cooling and heat dissipation effect.

[0046] As shown in Figure 1 and Figure 2As shown in the figures, the adjusting assembly 6 comprises a driving shaft 61, a first driven shaft 62 and a second driven shaft 63 which are rotatably installed in the air outlet box 4, the driving shaft 61, the first driven shaft 62 and the second driven shaft 63 are fixedly connected with a rotating shaft 53, the driving shaft 61 drives the first driven shaft 62 and the second driven shaft 63 to rotate through a transmission assembly, and the air outlet box 4 is rotatably provided with an adjusting shaft 64, one end of the adjusting shaft 64 extending into the air outlet box 4 is fixedly connected with the driving shaft 61, and the other end of the adjusting shaft 64 extending out of the air outlet box 4 is fixedly provided with an adjusting handle 65.

[0047] In the embodiment, the adjusting assembly 6 can adjust the opening degree of the cold air outlet 52.

[0048] If the temperature of the electrical component is higher than the predetermined temperature range, the cold air outlet 52 can be fully opened to increase the air flow of the low-temperature cold air, and a large amount of low-temperature cold air can quickly take away the heat generated by the electrical component, thereby achieving the effect of efficient cooling and heat dissipation, and solving the problem of economic loss caused by damage of the electrical component due to overheating.

[0049] If the temperature of the electrical component is not much higher than the predetermined temperature range, the cold air outlet 52 can be partially opened to reduce the air flow of the low-temperature cold air, thereby reducing the energy consumption of the refrigeration air conditioner 3 while ensuring the cooling and heat dissipation effect.

[0050] In the embodiment, the transmission assembly can adopt a belt transmission structure or a chain transmission structure.

[0051] Taking the belt transmission structure as an example, two driving pulleys are fixedly installed on the driving shaft 61, and driven pulleys are fixedly installed on the first driven shaft 62 and the second driven shaft 63, and a synchronous belt is wound around each driving pulley and the corresponding driven pulley.

[0052] As shown in the figures, Figure 2 and Figure 4 As shown in the figures, the adjusting shaft 64 is fixedly provided with a rotating seat 66, the air outlet box 4 is fixedly provided with a fixed ring seat 67, the rotating seat 66 is rotatably installed in the fixed ring seat 67, and the outer side wall of the rotating seat 66 and the inner wall of the fixed ring seat 67 are both provided with limiting teeth 68 which are in mesh with each other.

[0053] In the embodiment, the limiting teeth 68 on the rotating seat 66 are in mesh with the limiting teeth 68 on the fixed ring seat 67, thereby limiting the rotation direction between the adjusting shaft 64 and the air outlet box 4, so that the sealing arc plate 54 can be stopped at any angle.

[0054] The end surface of the fixed ring seat 67 is provided with a measurement scale 7 for displaying the opening degree of the cold air outlet 52, and the circumferential wall of the rotating seat 66 is fixedly provided with an indicating mark 8.

[0055] In this embodiment, the operator can clearly see the opening degree of the cold air outlet 52 according to the indication of the indicator mark 8 and the measurement scale 7.

[0056] like Figure 1 As shown, the dust filter 21 is fixedly installed inside the air inlet box 2. The dust filter 21 is located between the air outlet of the refrigeration air conditioner 3 and the air inlet of the horizontal pipe 51.

[0057] In this embodiment, the dust filter 21 is used to filter the low-temperature cold air blown out by the air conditioner 3 to prevent dust particles or some flammable material particles in the air from entering the cabinet 1, thereby avoiding damage to electrical components caused by the accumulation of dust particles or flammable material particles inside the cabinet 1.

[0058] Furthermore, a dust removal port 22 is provided at the lower end of the side wall on which the air inlet box 2 is equipped with the refrigeration air conditioner 3, and a sealing door 23 is installed at the dust removal port 22.

[0059] In this embodiment, the dust removal port 22 is designed to facilitate the operator in cleaning the impurities accumulated inside the air inlet box 2.

[0060] The principle behind using this invention to cool and dissipate heat from electrical cabinets is as follows:

[0061] First, the temperature monitoring element 91 monitors the temperature of the electrical components in the upper and lower rows inside the cabinet 1 in real time. When one of the temperature monitoring elements 91 detects that the temperature of the electrical component exceeds the predetermined reasonable temperature range, it sends an alarm signal corresponding to the temperature to the corresponding alarm 92. The alarm 92 issues an alarm signal within the temperature threshold range based on the received temperature data to remind the operator.

[0062] At the same time, the alarm 92 will control the air conditioner 3 to start. After the air conditioner 3 starts, it blows low-temperature cold air into the air inlet box 2. After being filtered by the dust filter 21, the low-temperature cold air enters the horizontal pipe 51 through the opening at the end of the horizontal pipe 51, and then is blown into the cabinet 1 through the cold air outlet 52 on the wall of the horizontal pipe 51. The low-temperature cold air carries away the heat generated by the electrical components, and the low-temperature cold air that has completed the heat exchange with the electrical components becomes hot air.

[0063] The generated hot air then enters the air outlet box 4 through the connecting hole 41, and the hot air in the air outlet box 4 is then discharged through the air outlet vent 42. This achieves the purpose of cooling and heat dissipation.

[0064] The method for freely adjusting the opening degree of the cold air outlet (52°) is as follows:

[0065] Firstly, the operator determines the temperature range of the two rows of electrical components according to the alarm threshold of the alarm 92, and adjusts the adjustment range of the cold air outlet 52 according to the temperature of the electrical components.

[0066] Secondly, the operator rotates the adjusting handle 65, the adjusting handle 65 drives the adjusting shaft 64 and the driving shaft 61 to rotate, the driving shaft 61 drives the first driven shaft 62 and the second driven shaft 63 to rotate synchronously through the transmission assembly, and the rotation of the driving shaft 61, the first driven shaft 62 and the second driven shaft 63 drives the sealing arc plate 54 to rotate, so that the relative displacement between the sealing arc plate 54 and the cold air outlet 52 is generated, and the adjustment of the opening and closing degree of the cold air outlet 52 is realized.

[0067] Although the embodiments of the utility model have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to these embodiments without departing from the principles and spirits of the utility model, and the scope of the utility model is defined by the appended claims and their equivalents.
