浸入式電加熱器主要用于直接對流體接觸加熱的場合，具有熱交換快，熱效率高等特點，分為水用加熱器、油用加熱器、氣體用加熱器，加熱元件的功率密度：即電加熱元件單位發(fā)熱面積上的功率，它是電加熱元件極重要的參數(shù)，直接影響加熱器的使用性能及使用壽命，它的取值是一個非常專業(yè)的問題，受到許多因素的影響（如介質(zhì)的流速、溫度、物理和化學性質(zhì)及介質(zhì)流過加熱元件的方向等等）。

The immersion electrical heater is chiefly applied in the direct contact mode of fluid heating.It features fast heat exchange and high thermal efficiency.It has the varieties of water heater,oil heater and gas heater.Its heating element power density,I.e. the power per unit of heating area of the heating element,is an important parameter of the electrical heating element,which has a direct bearing on the performance and working life.The working out of the value is a highly specialized problem,being under the influence of many factors （media flow rate,tempt,physical and chemical properties and direction in which the medium flows past the element etc）.

 浸入式電加熱器 如果取值大則會引起過熱、結(jié)焦，嚴重時很快就會引起加熱元件的損壞，取值偏小，則會引起體積增大和成本的急劇增加，針對不同的用途的電加熱器，采取不同的功率密度。在結(jié)構(gòu)上的共同之處是采用了一塊管板上集束了若干根電加熱管，末端采用了支撐板或支撐管使所有電熱管形成 -個整體，減少介質(zhì)流動時對單根電熱管的振動，在加熱器中都裝有超溫控制裝置，作為電熱元件的保護裝置。

Taking a too-high value will mean overheating and sintering and in serious cases causes damage to the heating element.While taking a too-low value will mean a large volume and a drastic rise of cost.Depending on the different applications electrical heaters adopt different power density.One common thing in terms of structure is that one tubing plate carries a number of heating tubes,at the ends of which is a supporting plate or supporting tube to make all heating tubes an integral whole.That way vibration of single heating tube caused by medium flowing is reduced.In the terminal box the overheating control is fitted as a protection device of the electrical heating elements.

備注說明：

加熱器可采用碳鋼或不銹鋼，若加熱溫度較高，則在法蘭與接線盒之間需加一個散熱區(qū)，散熱區(qū)長度隨溫度而定。若溫度較低，則不設(shè)散熱區(qū)，具體情況請洽本公司技術(shù)部門。

• 可采用螺紋接口。

Notes:

• Heater may be made of carbon steel or stainless steel.Heating temperature is to be below 100℃.If heating is to be in the range between 100℃-200℃ a heat diffusion sector of 100 should be added bwtween the flange and terminal box,whose dimensions is A+100.If heating temperature needs to be even higher the heat diffusion sector shall be made longer.For specifics please contact our tech dept.
• Adopt the threaded connection.
