Description

Technical Field

[0001] The utility model relates to the field of dehumidification, in particular to an auxiliary dehumidification device for a cabinet air conditioner. Background Art

[0002] Humidity inside smart control cabinets has the greatest impact on electronic equipment. As humidity increases, water molecules more easily penetrate the materials. Excessive humidity can create "conductive paths" or arcing in electronic components, severely reducing circuit reliability. When the relative humidity inside the cabinet exceeds 100%, water vapor in the air condenses, forming condensation, which poses a significant threat to power grid security. Dehumidification methods for smart control cabinets include heating, air conditioning, dehumidifiers, and manual intervention. Due to their superior performance, cabinet air conditioners can simultaneously dissipate heat and dehumidify. Currently, cabinet air conditioners are widely installed in smart control cabinets in substations. These dehumidification methods typically rely primarily on the cabinet air conditioner, supplemented by dehumidifiers.

[0003] There are two main types of dehumidifiers. The first is a heating dehumidifier, which provides both heating and exhaust functions. This type of dehumidifier is an older product with a high failure rate, often experiencing problems such as a damaged heating plate, fan failure, and burnout. The second type is a condensing dehumidifier. This dehumidifier offers higher dehumidification efficiency, condensing moisture inside the cabinet into water, which is then drained to the bottom of the cabinet via a silicone drain pipe, passing through the sealing mud and flowing into the cable trench. However, this type of dehumidifier is prone to failure and, due to the drain pipe's limitations, can only be installed at the bottom of the cabinet. Furthermore, the dehumidifier's large size significantly limits its installation location. Therefore, intelligent control cabinets generally only have one dehumidifier installed at the bottom of the cabinet.

[0004] Therefore, in order to solve the above technical problems, it is urgent to propose a new technical means. Utility Model Content

[0021] Furthermore, the dehumidification module is fixed in the cabinet by magnetic adsorption.

[0022] The beneficial effects of the present invention are as follows: the present invention designs a small-volume dehumidification module, which can be installed at any position in the cabinet, breaking the limitation that the dehumidification module can only be installed at the bottom of the cabinet, making the installation more flexible, so that the dehumidification module can be installed in places with higher humidity in the cabinet, thereby improving the dehumidification speed; and the present invention also arranges a water absorption monitoring module at the drain pipe, which can not only monitor the water leakage of the drain pipe in real time, but also absorb the leakage in time to prevent the leaked water from flowing back into the cabinet.

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0025] Figure 2 This is a structural diagram of the water absorption monitoring module of the utility model. DETAILED DESCRIPTION

[0026] The following is a further description of the present invention with reference to the accompanying drawings:

[0027] The auxiliary dehumidifiers of existing cabinet air conditioners are limited in size and can only be installed at the bottom. This results in low dehumidification efficiency and requires extended working hours to achieve dehumidification, which wastes electricity resources. In addition, the probability of failure increases after the working time of the auxiliary dehumidifier is extended, and ultimately it is difficult to achieve the purpose of dehumidification. Moreover, the higher the dehumidifier is installed, the more likely it is to leak. Simply changing the position of the auxiliary dehumidifier cannot solve the problem.

[0028] The utility model provides an auxiliary dehumidification device for a cabinet air conditioner, comprising a dehumidification module and a control module;

[0029] The dehumidification module is fixedly arranged in the cabinet; the dehumidification module includes a condensation module and a water collection tank. The condensation module is used to condense water vapor in the air inside the cabinet. The water collection tank is arranged below the condensation module and is used to collect condensed water from the condensation module. The condensed water in the water collection tank is discharged from the cabinet through an internal drainage pipe.

[0030] The control input end of the condensing module is connected to the control output end of the control module;

[0031] To avoid water leakage caused by installing the dehumidification module at a high position, the present application is provided with a water absorption monitoring module, which is wrapped around the connection between the internal drainage pipe and the external drainage pipe to monitor whether there is water leakage at the connection and absorb the water leakage at the connection. Even if there is leakage, the water can be absorbed, reducing the impact of the leakage on the surrounding working machines.

[0032] The output end of the water absorption monitoring module is connected to the input end of the control module.

[0033] Since the dehumidification module in the present application is relatively small in size, it can be flexibly arranged in the cabinet; and the dehumidification module in the present application can be one or more, and can be arranged according to needs. The multiple dehumidification modules can be installed at any position inside the cabinet, and can achieve uniform coverage of the entire cabinet interior, thereby improving the overall dehumidification efficiency; this method can ensure that all parts of the cabinet can be effectively dehumidified, avoiding problems caused by excessive local humidity; wherein, multiple dehumidification modules are controlled by a control module; it is preferred to set the dehumidification module in a place with higher humidity, so as to improve the dehumidification efficiency of the dehumidification module.

The alarm device can issue an alarm through any one or more combinations of sound, light, and voice prompts. Through the aforementioned device, a timely warning can be issued when a water leak occurs at a pipe connection. Even if the leak is small and cannot be detected by the humidity sensor in a timely manner, the water absorption monitoring device will absorb this small amount of leaking water, thereby preventing it from affecting the surrounding area.

[0042] In this embodiment, the condensation module adopts a semiconductor condensation dehumidification device;

[0043] The semiconductor condensation and dehumidification device includes a semiconductor refrigeration plate, a cooling plate, a heat sink, an isolator disposed between the cooling plate and the heat sink, and a heat dissipation fan, and a housing II enclosing the semiconductor refrigeration plate, the cooling plate, the heat sink, the isolator, and the heat dissipation fan. The connection relationship of the semiconductor condensation and dehumidification device is existing and will not be described in detail here. This application is based on the existing semiconductor condensation and dehumidification device, and reduces the size of each component to achieve installation at any position.
