液压管路中的油液，由于其相互间的摩擦及油与管壁之间的摩擦所生成的热，是油温上升，一般而言石油系的液压油限于55度，在此温度以上时，由于粘度减低，增加漏油，阀的性能降低，泵的效率也下降，油的劣化等问题也随之而生，为防止以上缺点，故使用冷却器。
目前的产品种类有：
1、KMLC系列油冷却器是由一般的裸管式冷却管结构而成，因管数多，排列密集，散热效果***佳。
2、HT系列油冷却器是由附有铁片的冷却管结构而成，能增加冷却面积，使冷却器小型化。
3、HH系列油冷却器是由一般的裸管式冷却管结构而成，易于清洗，为一般用经清型冷却器。
4、DT油冷却器是由滚牙式冷却管而成，滚出的牙面，散热面积较大。
发热量大于散热量，相差的热量若用冷却器则可防止油温上升，此称为冷却器的热交换量Q，根据此Q选定冷却器，计算所用记号如表A。
Q=（T1-T2）*60*O.85*0.45*WS=(t2-t1)*60*1*1*Wt
2、冷却水出口温度t2(℃)
相对于冷却水出口温度的冷却水量的比率油： 冷却水=1：0.5～1 (注)此时冷却水的流速（冷却水出入配管内流速）须在0.5～1.5m/s的范围
t2=Q/60*WT+t1(℃)。
3、平均温度差△tm(℃)
以作动油与冷却水出口、入口温度差为基准，求对数平均温度差△tm。
对数平均温度差
做动油T1→T2
冷却水t2→t1
△t1=T1-t2，△t2=T2-t1
由上式△t1与△t2，补正如下：由表B所求的对数平均温度差△t'm，乘上补正系数X,X如下图所示，由表C求得。
（t2-t1）/(T1-t1)=Y(T1-T2)/(t2-t1)=Z
△tm=△t'm*X。
注：补正系数求自温度效率和容量比，如表C所示。
4、传热面积A(m²)
A=Q/（△tm*K）。
5、总括传热系数K（Kcal/m²℃*h）
K值视冷却水量‘液压油粘度的不同而异，一般为K=200～650Kcal/m²℃*h，KOMPASS多管式冷却器，K=350～500Kcal/m²℃*h
1/K=d1/(d2hr)+1/hs+rs。
6、由马达输出功率，算出必要交换热量
发热量E（Kcal/hr)=输出功率W(KW)*860
（Kcal/hr*KW)交换必要热量Q（Kcal/hr)=Ex∝∝:
热交换系数
一般机械无热源者取0.4～0.6
塑胶机械、压铸机械等有热源者取0.6～0.8 。
