In the example of fig. 1, on a certain cross section of body 11, backing plate 12 has blocked the latter half of this body 11 to intercept liquid refrigerants, and limit ventilation space c between the roof of backing plate 12 and the inwall of tube chamber 10, ventilation space c is as the circulation passage of cold media gas.
As shown in Figure 2, two backing plates 12 are formed as the arc recessed towards direction away from each other.Because gas outlet b is between two backing plates 12, therefore alternatively, each backing plate 12 is formed as towards the recessed arc in the direction away from gas outlet b.Thus, the reliability that backing plate 12 is connected with body 11 can be improved, ensure the liquid barrier function of backing plate 12.
Specifically, in knockout 1, because refrigerant mixture is flowed towards gas outlet b by air inlet a, refrigerant applies towards the impulsive force on the direction of gas outlet b when flowing through backing plate 12 to backing plate 12, therefore backing plate 12 is recessed into towards the direction away from gas outlet b, make, under the long-term impact of refrigerant mixture, still to coordinate with the internal perisporium of body 11 or periphery wall after backing plate 12 deforms, avoid backing plate 12 crooked or topple over.
Particularly, the ventilation space c place limited between each backing plate 12 and tube chamber 10 is provided with filter screen 13, and namely filter screen 13 is located on backing plate 12.Like this, when refrigerant flows through filter screen 13, backing plate 12 can share certain impulsive force, avoids filter screen 13 stressed excessive and damaged, and facilitates the fixing of filter screen 13.
