Hot glue pad.
The present apparatus utilizes semiconductor refrigerating technology, and the moisture in air is made constantly to condense into water heel row in condensation plate surface
It offers for sale outer, quickly reduces cabinet humidity.It is empty in cabinet due to use of the dehumidification device in cabinet when environment temperature change dramatically
It draws last breath smaller to humidity, therefore condensation will not be generated again.The device is also equipped with dedicated intelligentized control method instrument, by continuous
The variation for measuring the relative humidity in cabinet, automatically controls the start and stop of dehumidifier apparatus, device can not only effectively reduce wet in cabinet
Degree eliminates condensation, and very energy saving, especially suitable for the preferable high-tension switch gear of compact-sized, leakproofness.
Device includes controller and dehumidifier two parts.Controller part structure chart such as Fig. 1, including it is power module, warm and humid
Spend acquisition module, central processing module, Dehumidification controlling module, communication module.The course of work is as follows: after controller is powered, power supply
For module to modules direct current supply, power module output voltage is direct current 5V and two kinds of direct current 12V, and output power is less than 3W.
Temperature and humidity acquisition module acquires the temperature and humidity data in cabinet, and is transferred to central processing module.Central processing module according to
Temperature and humidity value determines whether to start Dehumidification controlling module.When cabinet humidity is more than threshold value, and temperature is greater than minimum temperature, open
Dynamic Dehumidification controlling module.Dehumidification controlling module is made of relay and its driving circuit, when starting Dehumidification controlling module, relay
Device closure provides 220V power supply to dehumidifier.Man-machine interface is mainly made of key, charactron, light emitting diode etc..Man-machine boundary

Dehumidifier mainly by shell, large power supply module, fan guard, fan, cooling fin A, semiconductor chilling plate,
Heat insulating mattress, cooling fin B, stainless steel screw, the heat-insulated rubber mat of screw, water receiving funnel, aqueduct composition.Semiconductor chilling plate is entire
The core devices of dehumidifier, when it is passed through direct current, one end refrigeration, other end fever.Cooling fin A is close to cooling piece heat
End, cooling fin B are close to cooling piece cold end.Heat insulating mattress is installed, heat insulating mattress avoids cooling fin A and B from directly connecing between cooling fin A and B
Touching, and protect cooling piece.It is fixed between cooling fin A and B by stainless steel screw, the heat-insulated rubber mat of stainless steel screw housing screw,
Cooling fin A and B is avoided to conduct heat by stainless steel screw.Fan is installed on cooling fin A, keeps cooling piece hot end heat quick
Heat dissipation, it is ensured that cooling piece cold end is effectively freezed.Large power supply module provides the electricity of direct current 12V, 30W for cooling piece and blower
Source.Aqueduct is connected to the water outlet end of water receiving funnel, so that condensation flow is offerd for sale outer.The course of work is as follows: when controller is removed
After wet device power supply, dehumidifier is started to work.Large power supply module provides power supply for cooling piece and blower.After cooling piece is powered,
Cold end refrigeration, hot end fever.Blower makes cooling piece hot end heat start to spread, and temperature reduces.Cold end is low after being powered because of cooling piece
In air themperature in cabinet, hot end is higher than air themperature in cabinet, and cold and hot end temperature difference is basically unchanged.So when blower makes heat
When temperature being held to reduce, cold junction temperature is further decreased, and can effectively freeze.Because cooling fin B temperature is lower than air themperature in cabinet, so
Moisture in cabinet in air can constantly be condensed into water, be gathered on cooling fin B.When condensed water is enough, water can be dropped onto and be connect
In hyponome, then outside aqueduct outflow cabinet, achieve the purpose that reduce air humidity in cabinet.
