Description

Technical Field

[0001] The utility model belongs to the technical field of motor loads, and in particular relates to a motor load life monitoring station based on a high-efficiency heat dissipation channel. Background Art

[0002] When conducting a life test on a DC motor load, in order to verify the reliability of components such as relays, it is necessary to set a dummy load that simulates surge current with a resistive load to conduct the life test. The current monitoring station includes a monitoring station body and a load cabinet. The monitoring station body is connected to the load cabinet control and power supply. Since the dummy load also generates a lot of heat, the load cabinet needs to be cooled. Currently, cooling mainly relies on passive cooling or active fan cooling, which has poor cooling effect and affects the working condition and life of the load cabinet. Utility Model Content

[0003] In order to solve the problems existing in the above-mentioned prior art, the utility model provides a motor load life monitoring station based on a high-efficiency heat dissipation channel. By adding a heat dissipation channel, the hot air in the load cabinet will be discharged along the heat dissipation channel through the opening at the top, forming a chimney effect, thereby achieving the purpose of efficient heat dissipation.

[0004] The specific technical solution adopted in this utility model is:

[0005] A motor load life monitoring station based on a high-efficiency heat dissipation channel includes a load cabinet and a system load located in the load cabinet. The load cabinet is connected to the monitoring station. A fan is provided on the side wall of the load cabinet. The load cabinet is also provided with a heat dissipation channel. The heat dissipation channel is located in the center of the load cabinet and passes through the load cabinet from top to bottom. The system load is arranged along the circumference of the heat dissipation channel. The side wall of the heat dissipation channel located in the load cabinet is provided with an exhaust port. External air enters the load cabinet with the help of the fan and is discharged through the heat dissipation channel along the exhaust port.

[0006] Multiple groups of horizontally arranged partitions are arranged in the vertical direction in the load cabinet, and the chambers in the load cabinet are divided by the partitions to form multiple groups of installation chambers. The heat dissipation channels pass through the partitions of each group of installation chambers in turn, and each group of the installation chambers is provided with multiple groups of exhaust ports and fans.

[0007] The exhaust port is located above the installation chamber, and the fan is located below the installation chamber.

[0008] The bottom of the heat dissipation channel located outside the load cabinet is provided with an air inlet, and multiple groups of the air inlets are arranged around the heat dissipation channel.

[0009] The load cabinet is also provided with a baffle at the fan location. One side of the baffle is hinged to the load cabinet, and the other side of the baffle is provided with a plug-in piece. The load cabinet is provided with a slot matching the plug-in piece. The baffle forms a detachable plug-in match with the load cabinet with the help of the plug-in piece, and the air inlet end of the fan is dustproof with the help of the baffle.

[0010] An induced draft fan is also provided at the outlet of the heat dissipation channel, and the air in the load cabinet enters the heat dissipation channel and is discharged with the help of the induced draft fan.

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

[0012] In the present invention, a heat dissipation channel is added to the load cabinet, and a fan draws cold air from the outside into the load cabinet. Due to the high density of the cold air, the pressure inside the load cabinet also increases. Since the pressure inside the load cabinet is greater than the pressure in the heat dissipation channel, the hot air in the load cabinet will be discharged along the heat dissipation channel through the opening at the top, forming a chimney effect, thereby achieving the purpose of efficient heat dissipation.

[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0021] Specific embodiments, such as Figure 1-6As shown, the utility model provides a motor load life monitoring station 3 based on an efficient heat dissipation channel 5, comprising a load cabinet 1 and a system load 2 located in the load cabinet 1, the load cabinet 1 being connected to the monitoring station 3, a fan 4 being provided on the side wall of the load cabinet 1, and a heat dissipation channel 5 being further provided on the load cabinet 1, the heat dissipation channel 5 being located in the center of the load cabinet 1 and passing through the load cabinet 1 from top to bottom, the system load 2 being arranged around the heat dissipation channel 5, and an exhaust port 6 being provided on the side wall of the heat dissipation channel 5 located in the load cabinet 1, the outside air enters the load cabinet 1 with the aid of the fan 4 and is discharged through the heat dissipation channel 5 along the exhaust port 6.

[0022] The system load 2 in the present invention is a dummy load that simulates a motor load. Currently, heat dissipation within the load cabinet 1 is primarily achieved through passive cooling or active fan 4, which results in poor heat dissipation and affects the operating condition and lifespan of the load cabinet 1. Therefore, the present invention adds a heat dissipation channel 5 to the load cabinet 1. Fan 4 draws cool air from the outside into the load cabinet 1. Due to the high density of the cool air, the pressure within the load cabinet 1 also increases. Because the pressure within the load cabinet 1 is greater than the pressure within the heat dissipation channel 5, the hot air within the load cabinet 1 is discharged along the heat dissipation channel 5 through the opening at its top, creating a chimney effect, thereby achieving efficient heat dissipation.

[0023] like Figure 1 and Figure 4 As shown, multiple sets of horizontally arranged partitions 7 are vertically arranged within the load cabinet 1. The partitions 7 separate the chambers within the load cabinet 1 into multiple groups of mounting chambers. The heat dissipation ducts 5 sequentially pass through the partitions 7 of each group of mounting chambers. Each group of mounting chambers is provided with multiple sets of exhaust ports 6 and fans 4. The partitions 7 separate the load cabinet 1 into multiple mounting chambers, preventing heat accumulation caused by the transfer of hot air between the various mounting chambers. The exhaust ports 6 are provided on each vertical surface of the heat dissipation ducts 5, and multiple fans 4 are provided in each mounting chamber, further improving the overall heat dissipation efficiency of the load cabinet 1.

[0024] like Figure 1 As shown, the exhaust port 6 is located above the installation chamber, and the fan 4 is located below the installation chamber. Cold air has a higher density and sinks below the installation chamber, while hot air has a lower density and floats above the installation chamber. Therefore, the positioning of the exhaust port 6 and the fan 4 allows the cold air to flow upward through the exhaust port 6 along with the hot air, allowing the cold air to pass through the entire installation chamber, thereby improving the cooling and heat dissipation effect.

[0025] like Figure 1 As shown, the heat dissipation channel 5 is provided with an air inlet 8 at the bottom outside the load cabinet 1. Multiple groups of air inlets 8 are provided around the heat dissipation channel 5, and multiple groups of air inlets 8 are also provided at the bottom of the heat dissipation channel 5, which can increase the heat exhaust volume of the heat dissipation channel 5, thereby improving the heat dissipation efficiency.

[0026] like Figure 1-3 and Figure 5-6 As shown, a baffle 9 is further provided on the load cabinet 1 at the fan 4, one side of the baffle 9 is hinged to the load cabinet 1, and an insert 10 is provided on the other side of the baffle 9. A slot 11 matching the insert 10 is provided on the load cabinet 1, and the baffle 9 forms a detachable plug-in match with the load cabinet 1 with the help of the insert 10. The air inlet end of the fan 4 is dust-proof with the help of the baffle 9. When the motor load is not working, the fan 4 is blocked with the help of the baffle 9 to prevent most of the dust in the air from drifting into the load cabinet 1 along the fan 4. When the motor load is working, the baffle 9 is opened. Under the action of its own weight, the baffle 9 will be fixed at an inclined angle to the load. In addition, a filter is provided on the ventilation duct of the fan 4 to prevent foreign matter from entering the load cabinet 1 when the fan 4 is working.

[0027] like Figure 1 As shown, an induced draft fan 12 is further provided at the outlet of the heat dissipation channel 5. The air in the load cabinet 1 enters the heat dissipation channel 5 and is discharged with the help of the induced draft fan 12. The hot air in the load cabinet 1 is introduced into the heat dissipation channel 5 and discharged by the induced draft fan 12, thereby preventing the air from forming an air circulation in the load cabinet 1 and being unable to enter the heat dissipation channel 5.
