ã€Academic Test Track】Aucma PTC Heater Experience Report
Winter is coming, and the temperature is getting colder and colder. As a child living in the South, I long for the heating in the North. Since no heating in the South has become a reality in the winter, then you have to think of ways to “self-preservationâ€. Generally, there are two choices: warm air-conditioning, or open-air heating. In places with lots of people, such as offices, air conditioning is suitable. . Electric heaters are cheap and easy to move around. Many people are using them. They are just participating in the activities of Yi Xun. They have won an electric heater for the children in the south of the country. They are warm and warm.

In the small box received in the office, I can't believe my hand, and I can't believe it!
Go home and unpack:
A manual, an Aucma small electric heating, this is a PTC electric heating (PTC is a short for ceramic electric heating element), characterized by fast heating, high heat conversion efficiency, the price is relatively cheap, there are disadvantages, look back.
Above is the switch button, probably because of the small size, and did not increase the temperature control adjustment button.
At the top is the indicator of the brand and the center of the lower part is an indicator. The upper and lower silver flashing strips are made of plastic material. The printing is clear, but the splicing is still somewhat rough, and the thermal insulation performance will be discussed later.
The middle part of the heater adopts a small-diameter metal net cover design. The front face is hot-proof, and the small round hole on the back facilitates heat removal by the fan. The whole is fixed by four screws on the back, and the design is reasonable.
The bottom is the product nameplate, indicating: rated voltage 220V, rated power is 500W, there is a switch on the left side of the anti-fall.
The bottom of this small switch, more prominent than the bottom, when placed properly, the internal and this switch is connected to form a complete circuit, otherwise it will power off, for the use of safe design.
The wire used is relatively thick, with a length of 1.25m or so. The plug has a regular structure and is marked to withstand a current of 10A 250V higher than the rated voltage, indicating that the line is affordable.
[Dismantling]
Look at the internal materials and wiring design, and visually test the heating rate, a cross-knife, four screws, you can open the back cover.
Well, this is internal, and the fuselage is made of plastic material. The internal wires and components work well. The card design is also reasonable, but the traces are a little messy.
The lower right corner is the circuit board. Because the PTC group is surrounded by a plastic shell, the high temperature emitted has little effect on the circuit board below. However, it is better to separate the circuit boards separately to reduce the risk of use. The device did not cut corners. This was praised.
Power consumption:
In several periods of time, intercepted data shows that basically between 500-550W, corresponding to the rated power, so the product does not have a virtual standard, as for the power consumption of 500W, considering its volume, this power is considered moderate.
Warming situation:
One of the advantages of the PTC group is that the temperature rises quickly. In about 10 seconds, the heating plate can heat up to 100 degrees Celsius, and the heating rate is faster.
Thermal insulation:
Internal heat insulation is a serious problem. If the internal components are baked at high temperatures for a long time, the life expectancy can be imagined. This time, the Arkema heater is surrounded by a circle of thick plastic around the PTC group. So when running, the temperature around the interior space is low.
[Feelings]
Wind and hair angles:
The test adopts a lighter napkin with a ruler and a lighter material. When the distance is 25cm, the wind is not felt. When the distance is 15cm, there is a breeze. When the wind is close to the net surface, the wind can be felt. Of course, this is related to the air blow angle and looks down.
Hair angle:
The flat angle needs to be close enough to feel the hot air, but the angle above the slant, you can feel the hot air in about 20cm, so if you want to get warm, you need to find a good angle, and the heat range is small. This is a big PTC heater. Disadvantages.
The actual heating effect, placed obliquely above the location, 5cm away from the outlet (should be the location where most people bake feet), measuring temperature after 10 minutes, the sock's temperature at 50 degrees Celsius, can play a heating effect.
[ to sum up]
advantage:
Cheap, adequate materials
Warming and high portability
The fall switch and internal insulation are good
Disadvantages:
Small size, small heating area
Slight noise and power consumption
Without temperature regulation
This mini Aucma PTC heater can fit on the desktop (hand), bottom (foot) on both sides, high portability, heating speed, thermal insulation temperature control in place, high security, but the inherent heating of the PTC heater The two disadvantages of area and noise are also outstanding in this small PTC heater. As for how to choose a suitable electric heater, you have to integrate the volume, functional requirements, price factors and many other aspects, if you like the small portable can use this Aucma as a candidate.
Original projector bulb lamp is imported from the original brand factory, and the quality is worthy of assurance. At the same time, it has high brightness and durable life, which can present a relatively clear image. It is suitable for places with high requirements for product quality, such as movie theaters, golf courses, schools, etc.
