Description 

A specially designed new type of product for space heaters, which uses constant resistance or constant temperature electric heating elements and specially designed aluminum profiles - heat conductors (diffusers) for assembly. The structure of this product increases the heat conduction area through the fins of the "heat sink", that is, the heat radiation area at the center of the heat source is multiplied. The pin in ratio of the fins is as high as 8.5 (in the pin in ratio, pin refers to the height of the fins of the heat sink, and fin refers to the distance between adjacent fins. The pin in ratio is divided by the height of pin (excluding the base thickness), and a higher pin in ratio means that the effective heat dissipation area of the heat sink is larger, Representing the more advanced aluminum extrusion technology. In a limited space, a heat conductor can maximize the thermal diffusion area of the heating source, which can easily generate a chimney effect, making the spatial heat transfer uniform and fast; Therefore, the UHT type uniform heater has good heat transfer effect and is fully capable of meeting the special needs of heating, insulation, and dehumidification in certain control systems using air as the heat transfer medium, to prevent the formation of dew condensation due to environmental temperature changes.

1. High wing to wing ratio maximizes the thermal diffusion area of the heating source;

2. High heat transfer efficiency, the "chimney" effect ensures uniform and fast heat transfer;

3. Modular design, convenient selection; The installation type can be customized;

10 series and 20 series (non explosion-proof) uniform heaters using a single ended heating rod as the heating element, with 1.5mm2 glass fiber high-temperature braided wire (wire colors: red, white, black, random) as the lead wire. The heating element is produced in one piece. The customer has special requirements for the diameter/color of the fiberglass lead wire. Please specify it when placing an order to facilitate the production and ordering of heating elements;

For 20 series uniform heaters with explosion-proof requirements or customized requirements, their leads are all made of 3 * 1.5mm2 halogen-free flame-retardant high-temperature cables with EWKF performance, and are usually crimped at the outlet of the heating element;

（6）Bracket code: represented by a 2-digit number.

Bracket code range for 10 series : 01-19；

Bracket code range for 20 series : ：21-29；

Precautions:

1. The thermal conductivity data of the uniform heater mentioned in this instruction is for reference only and needs to be tested when practical

2. Allowable error of working voltage: not greater than 1.1 times its rated value. The casing should be effectively grounded.

3. Working environment: The relative humidity shall not exceed 95%, and there shall be no explosive, flammable, or corrosive gases.

4. The 20 series uniform heater has explosion-proof products and uses PTC heating modules. Please refer to the ordering data sheet;

5. The lead wire diameter of non explosion-proof uniform heaters is usually related to the power of the single end heating rod. If not specified by the customer, fiberglass wires will be supplied; Explosion proof products usually use 1.5mm2 EWKF silicone rubber wire;

6.  When the PTC heating module is used as a heating element, the nominal power must be an integer multiple of 50W; According to the material characteristics of PTC heating elements, the power output has a strong discrete type, with a maximum power error range of ± 20%. The nominal power of the PTC heating module usually refers to the maximum thermal power output in a 0 ℃ environment, which is limited by the Curie point temperature of the PTC heating element. As a constant temperature device, the power of PTC heater is constantly changing. If the heat dissipation conditions remain unchanged, it will be relatively stable within a power range. Its power is directly related to its heat dissipation status and cannot be calculated generally. Based on testing experience, it is recommended to determine the actual working output power at room temperature by 50% of the nominal power when designing and selecting.
