容积式换热器

换热器网给大家详细介绍一下容积式换热器。

容积式换热器

是利用冷、热流体交替流经蓄热室中的蓄热体(填料)表面,从而进行热量交换的换热器,间壁容积式换热器的冷、热流体被固体间壁隔开,并通过间壁进行热量交换的换热器,因此又称表面式换热器。

容积式换热器产品特点

1、换热器

热媒温降大。汽水换热时,凝结水出水温度约50℃,回水管上下需设疏水器,给使用维修带来方便,水-水换热时,热温降为同型换热器的2~2.5倍,120~150℃的高温热水换热后可降至70~75℃。

2、容积式换热器换热效果好,散热效果好,散热损失小,节能。同时,以蒸汽为热媒时,能回收约占整个换热量的15%凝结水热量。

3.换热部分为改进的快速换热器,传热系数较离,换热量大,相同容积的该产品的换热量分别相当于传统容积式换热器的5-8倍。

4、冷水区小,容积利用率高。

5、保持了容积式换热器贮水量大,水头损失低,供水安全稳定,方便清垢之优点。

Volume type heat exchanger is the use of cold and hot fluid alternate flows through the heat storage room in the heat storage body (filler) surface, to thereby carry out heat exchange of heat exchanger, volume partition for heat exchanger of cold and hot fluid separated by a solid partition wall and through partition wall heat exchange of the heat exchanger, because this also known as surface type heat exchanger.

The characteristics of volume type heat exchanger

1, heat exchanger heat medium temperature drop. When the steam water heat exchange, the water temperature of the condensate water is about 50, and the water return pipe is provided with a hydrophobic device, which brings convenience to the use and maintenance, and the heat temperature drop is 2.5 ~ 2 times of the same type heat exchanger, and can be reduced to 75 to 120 after 150 ~ 70.

2, the volume of heat exchanger for heat effect, good heat dissipation, heat loss of small, energy saving. At the same time, the steam is the heat medium, can recover about 15% of the whole heat transfer.

3 heat transfer part for the improvement of the fast heat exchanger, heat transfer coefficient, heat exchange, the same volume of the product's heat transfer is equivalent to the traditional volume of 5-8 times.

4, the cold water area is small, the volume utilization rate is high.

5, maintain the volume type heat exchanger storage capacity, the water head loss is low, the water supply safety and stability, convenient cleaning advantages.
