隨著塑料領域擠壓成型和各類工藝技術的不斷發展,對加熱/冷卻係統的需求日益增長。通過風冷加熱器內膽(普通陶瓷)調節溫度,可以排除擠壓過程中的摩擦熱。
結構:加熱/冷卻係統由冷卻單元和加熱單元組成。
一、冷卻單元
由冷卻風罩、鼓風機及多種散熱器組成。冷卻風罩和鼓風機可以分別取下,安裝簡便。
1.冷卻風罩採用不鏽鋼闆或鍍鋁鋼闆製作,配有冷卻風機連接口、優化氣流導風片、排氣口以及接線盒,外觀精美。
2.冷卻風機。
3.散熱器:根據散熱要求可選用紫銅闆散熱片、鋁闆散熱片、陶瓷散熱片、外風道鑄鋁、內風道鑄鋁及液體冷卻式鑄鋁。
二、加熱單元
採用電加熱方式,電熱元件可選用礦物絕緣加熱器、雲母加熱器、陶瓷加熱器、鑄鋁加熱器或鑄銅加熱器。
我們可以根據客戶所需要的加熱和散熱功率來設計加熱與散熱麵積的比率。
我們既可提供單相供電的,也可以提供三相供電的電熱圈和鼓風機。
With the field of plastic extrusion and the continuous development of the various types of technology, the growing demand for the heating / cooling system. Through the system to adjust the temperature, can be excluded during the extrusion process difficult to control the frictional heat. Improve the quality of the molding of the material (especially when dealing with PVC material), extruders, injection molding machines and blow molding machines tube state-of-the-art heating / cooling system.
Structure:The heating / cooling system by the cooling unit and the heating unit.
Cooling unit: by cooling air cover, blower and a variety of radiator. Cooling hood and blowers can be removed, and easy to install.
1.the cooling fan cover is made of stainless steel or aluminized steel production, with a cooling fan connector to optimize the airflow wind guide piece, the exhaust port and the junction box, attractive appearance.
2.the cooling fan.
3.Radiator: According to the cooling requirements can choose copper plate heat sink, aluminum heat sink, ceramic heat sink, the outer duct cast aluminum, inner duct cast aluminum and liquid-cooled aluminum.
Second, the heating unit: electric heating, the heating element can be used mica heater, ceramic heater, cast aluminum heater or copper heater.
We can design according to the customer needs heating and cooling power ratio of the area of heating and cooling.
We have been able to provide single-phase power supply, can also provide three-phase power supply heater and fan.
陶瓷加熱器
陶瓷具有絕緣性,因此陶瓷加熱器可處理760℃的溫度。陶瓷加熱器的柔軟可形成各種加熱器直徑。遺憾的是,陶瓷的優點也是其弱點,由於它能存儲元件金屬絲産生的熱量,因此人們很難控製陶瓷加熱器的溫度。另外,陶瓷加熱器在拆裝過程中容易損壞,特別是升溫以後,加熱器會變得比較鬆散,給安裝帶來不便。陶瓷加熱器不能受到汙染這一特性也限止了這類加熱器的應用範圍。
●The ceramic heater
Because of the high temperature ceramic insulation, the ceramic heater can be processed to a temperature of 760℃. The. The soft ceramic heater may be formed various heaters diameter. Unfortunately, the advantages of the ceramic is also its weakness, due to the heat generated can store element wire, so it is difficult to control the temperature of the ceramic heater. This causes unnecessary waste, in plastic an earlier stage of the production process, which is particularly prominent. In addition, the ceramic heater is easy to damage during disassembly, especially after the temperature, the heater will become more loose, to install the inconvenience. The ceramic heater of this feature can not be contaminated and also limiting the scope of application of such a heater.
