In this embodiment, the circuit board 33 includes a voltage regulator circuit, which is responsible for converting the input dc power into dc power required by the PTC heating element 312 and the fan 32, and the two circuits are controlled independently via the switch and the knob. The DC power source of the input circuit board 33 has two parts, one is the power supplied by AC-DC conversion filtering, and the other is the DC power from the outside; the direct current power supply is divided into a path to supply a power supply 34 for endurance, and the on-off protector is used for protecting the power supply 34 and can realize the function by using a silicon controlled rectifier or a relay. The power output by voltage stabilization is divided into one path and can be used as a mobile power supply for external electrical equipment.
In this embodiment, the heating assembly 31 and the fan 32 are disposed below the first inner liner layer 11 and above the first fire prevention layer 12, and heat is conducted and radiated into the receiving groove 111 of the case 1 through the thermal conductivity of the metal material of the first inner liner layer 11 and the fine holes of the first inner liner layer 11. The power supply 34 is disposed between the first heat insulating layer 13 and the first fireproof layer 12, and may be disposed on the side surface or the bottom surface depending on the space utilization. Since the power supply 34 is part of the heating cabinet 100 and therefore fire protection is already a concern in production and design, the power supply 34 is located outside the first fire resistant layer 12 where fire protection only needs to be considered for the battery and the electronic device to be heated.
It can be understood that, when the heating box 100 is used on line, the external power circuit supplies power to the circuit board 33 with rectification and charging functions, the power can be connected with direct current or alternating current through different circuits and connectors, the power is supplied through the rectification circuit of the circuit board 33 when the power is connected with alternating current, and the power is supplied through the voltage stabilizing circuit on the circuit board 33 when the power is connected with direct current. In addition, the power supply is divided into two paths after passing through the circuit board 33, one path is directly supplied to the PTC heating element 312 and the fan 32 through rectification, the other path is supplied to the power supply 34 for endurance through the charging circuit, and the power supply 34 on-off device is responsible for ensuring the safety of battery charging and the circuit connection and disconnection during off-line use. The switch controls the operation of the circulation fan 32, which may be designed for manual speed regulation, and may be adjusted and controlled by a knob on the control panel 6.
When the power supply is switched on, the fan 32 is used for circulating cold air, and the cold air blows the heating component 31 to be changed into hot air to circulate in the installation cavity 112 and the accommodating groove 111 of the box body 1. The batteries and electrical equipment which need to be heated are arranged in the accommodating groove 111, and because the PTC heating element 312 does not use resistance heating, has no red heat and has automatic constant temperature control without a control circuit, the equipment and the batteries which need to be heated can be safely heated to an ideal working temperature and are efficiently conducted into the accommodating groove 111 of the whole box body 1 through the thin-wall metal first lining layer 11.
The utility model discloses a heating cabinet 100 can form a little space of 30 ~ 50 degrees centigrade in the holding tank 111 of box 1, and this is that traditional heating methods can not satisfy, can show after the battery is heated to this similar temperature and improve outdoor live time to guarantee the safety and the reliability of some key operations, unmanned aerial vehicle uses, rescues for example. Meanwhile, the heating device can meet all heating requirements needed in field operation, and can heat insulating food, clothes and all equipment needing to keep warm besides the heating battery. By making full use of the safety features of the heating structure 3, it can be ensured that no potential safety hazard is generated during the heating process. The high-efficiency characteristic of the solar water heater can fully utilize heating energy (the efficiency can reach more than 90 percent), and fully utilize precious electric energy in cold outdoor environment.
When the heating box is used online, a direct current power supply or a nearby 220V alternating current power supply of an outdoor operation carrier is connected, the working mode of the heating box 100 is adjusted, the temperature in the box body 1 can be rapidly and safely increased, equipment needing to be heated is placed in the accommodating groove 111 of the box body 1 after the temperature is increased, the equipment is taken out for use during operation, and meanwhile, the used equipment is placed back into the accommodating groove 111 until the operation is finished. When the battery in the case 1 needs to be charged or discharged, the charger may be built in or out of the housing groove 111 of the case 1, and the charging/discharging state of the battery may be observed through the observation window 4.
When the heating box 100 is used off-line, the heating box 100 is heated to the highest temperature, the upper cover 2 of the box body 1 is prevented from being opened for many times, and the battery is heated and then the whole heating box 100 is carried for outdoor operation. Of course, off-line endurance may also be achieved by the power supply 34. The mass of the power supply 34 of 300wh is below 1.5KG, and the power supply can be used for about two hours with 100w of heating power; the mass of the 600wh power supply 34 is below about 3KG, and can be used for about 3 hours with 200w heating power.
