1. Heating wire heating source (far infrared, reflective, convection heater) is a very common type of heater. A concave mirror reflective heater is commonly known as a heater"Little sun"。Regardless of desktop or vertical, you can shake your head like a fan; Some have far-infrared capabilities and are free of noise.

The heating speed is faster. The disadvantage is that the heating wire is fragile, and large vibrations in the open state may cause damage to the heating wire.

2. Heat conduction oil heating source (electric oil tin) electric oil tint uses heat conduction oil as the heating source, which can set the temperature at will according to the need, no noise, no peculiar smell, long service life, no brightness, no oxygen consumption, the air is not as dry as the reflective type when used, and the heat source can last for 2 hours after shutdown, and the heating amount is often directly related to the number of its plates. Compared with other heating products, the heat dissipation is slow and consumes more electricity.

3. Halogen tube, quartz control heat source (reflective, cylindrical heater) This kind of heater is also more traditional, the shape is similar to the heating wire reflective heater, but the heating source used is a new generation of halogen tube or quartz tube, this kind of heater is cheaper and is more economical heating equipment in winter, and easy to move, but the service life is not as long as the electric heating oil.

4. Electric heating film electric heater: the shape is relatively thin, similar to the general shape of LCD TV. These heaters heat up slowly and cool down quickly when the power goes out.

As for whether it costs electricity, it depends on how much power it is, and the power can not be seen from 220V (rated voltage) and 50Hz (frequency) alone.

There should be a label on the heater to see how much power is generated. The electricity consumption per kilowatt per hour is an electricity word, and it can be calculated according to the local electricity price.

I haven't used it, I don't know if it's good or not, I've used Tongle brand gas heaters, household mobile ones.

The thermostat in the heater is 100 degrees and is normally open. When the temperature reaches 100 degrees, disconnect, suspend the work, and resume the work after the temperature is lowered.

Have you not received the goods yet? Then you can communicate with the store.

bandwidth, clock frequency, bus width; The cycle is 200ns, so the frequency is 5mhz, so the bandwidth is 5mhz 32bit 160mb s 20mb s.

Bus bandwidth refers to the total amount of data that a bus can transmit per unit of time (equal to the product of the width of the bus and the operating frequency), usually in mb s (mbps). The transmission rate of the bus, the bandwidth of the bus (bus bit width, 8 bits), (the bus operating frequency, the number of bus cycle clocks).

For example, if the clock frequency of the bus is 100MHz, the transmission period of the bus is 4 bus cycles, and the width of the bus is 32 bits, try to find the data transmission rate of the bus.

Method 1, solution: according to the clock frequency of the bus is 100hmz, get:

1 clock cycle is: 1 100MHz 0,01 s; The transmission period of one bus is: 0 01 s4 0 04 s

The bus width is 32 bits: 32bits 8 4b (bytes); The transmission rate of the bus The bandwidth of the bus is 4b (1 0 04 s) 100mb s.

Method 2: Note that one transmission period is equal to several clock cycles.

The transmission rate of the bus The bandwidth of the bus is (32 8)b (100mhz 4) 100mb s.

1.This kind of household appliance has no scientific and technological content, and it is directly disassembled to see if the heating circuit is open and the contact is poor.

2.Electrical appliances are dangerous. If you don't have experience, it's best to go to a special repair shop.
