It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0029] Please also read Figures 1 to 5 The utility model drawer-type low-voltage switch cabinet is described. The drawer-type low-voltage switch cabinet includes a cabinet body 10 and a heat dissipation system 20; the cabinet body 10 includes a plurality of accommodating spaces 101 spaced apart in the vertical direction thereof, a water-cooling space 102 provided at the bottom of each accommodating space 101, drawers 103 slidably connected to each accommodating space 101, and a water-cooling chamber 104 located on one side of the accommodating space 101; the heat dissipation system 20 includes a water-cooling component 21, a plurality of heat dissipation components 22, and a plurality of temperature sensors 23; the water-cooling component 21 includes a plurality of water-cooling coils 211, a water supply pipe 212, a circulation pipe 213, and a plurality of water-cooling coils 214. The ring pipe 213 and the water pump 214 arranged on the water supply pipe 212, the multiple water-cooling coils 211 are placed in a one-to-one correspondence in the multiple water-cooling spaces 102, the water supply pipe 212 and the circulation pipe 213 are in the water-cooling chamber 104, the water supply pipe 212 is connected to the water inlet ends of the multiple water-cooling coils 211, the circulation pipe 213 is connected to the water outlet ends of the multiple water-cooling coils 211, each heat dissipation component 22 is placed in a accommodating space 101, the heat dissipation component 22 is a heat dissipation fan 221, and each temperature sensor 23 is placed in a accommodating space 101.

[0030] Compared with the prior art, the drawer-type low-voltage switch cabinet provided by the utility model has a temperature sensor 23 installed in each accommodating space 101 for real-time monitoring of the temperature in each drawer 103. When the temperature is greater than a threshold value, the heat dissipation fan 221 is turned on for cooling. At the same time, a water-cooling space 102 is provided at the bottom of the drawer 103, in which a water-cooling coil 211 is installed for water-cooling the drawer 103. By adopting a simultaneous cooling method of water cooling and air cooling, the temperature in the drawer 103 can be quickly reduced to avoid problems such as excessive temperature affecting the insulation in the cabinet, aging of components, and electrical failure. In addition, the water inlet end of the water-cooling coil 211 is connected to a water supply pipe 212 for outputting water to the water-cooling coil 211, and the water outlet end is connected to a circulation pipe 213 for discharging the water in the water-cooling coil 211. This arrangement can keep the water in the water-cooling coil 211 at a relatively low temperature value at all times, thereby achieving rapid cooling of the drawer 103.

[0031] Specifically, a temperature sensor is installed at the water inlet of the circulation pipe 213, and two branch pipes are arranged at the water outlet, one branch pipe is connected to the water supply pipe 212, and the other branch pipe is connected to the external water tank, and solenoid valves are installed on the two branch pipes. Two water inlet branches are arranged at the water inlet of the water supply pipe 212, one water inlet branch is connected to the circulation pipe 213, and the other branch is connected to the external water tank, and solenoid valves are installed on the two water inlet branches. When the temperature sensor detects that the water temperature at the water inlet of the circulation pipe 213 is higher than the threshold value, that is, the water temperature is too high to be used for water cooling, the solenoid valve on the branch pipe connected to the water tank is turned on. The magnetic valve is opened, and the solenoid valve on the other branch pipe is closed to discharge the water in the water-cooling coil 211. At the same time, the solenoid valve of the water inlet branch connected to the water tank is opened to add water to the water-cooling coil 211 for cooling. When the temperature sensor detects that the water temperature at the water inlet of the circulating pipe 213 is lower than the threshold value, the solenoid valve on the branch pipe connected to the water storage tank is closed, the solenoid valve on the other branch pipe is opened, the solenoid valve of the water inlet branch connected to the water tank is closed, and the solenoid valve of the other water inlet branch is opened to allow the water in the water-cooling coil 211 to re-enter the water-cooling coil 211 through the circulating pipe 213 and the water inlet pipe for circulation and cooling.

[0032] Specifically, the cabinet 10 also includes an air supply chamber located on the other side of the accommodating space 101.

The water cooling coil 211 can reduce the temperature in the water cooling space 102, and the through holes 106 are provided on the partition 105, which is conducive to transmitting the cold air in the water cooling space 102 to the receiving space 101, and then to the drawer 103, so as to facilitate the cooling of the drawer 103.

[0034] In some embodiments, an improved implementation of the above-mentioned drawer-type low-voltage switch cabinet can be adopted as follows Figure 1 See the structure shown.
