Fig. 4 for convenient, has omitted condenser pipe 4 and supercooling tube 5 for for the schematic diagram of the flow process of refrigerant in condenser 1 is described among Fig. 4.As shown in Figure 4, housing 2 horizontally sets cylindraceous, be provided with the refrigerant inlet 2c that the cooling matchmaker flows on the barrel of axial centre being positioned at upside and roughly being positioned at, roughly be provided with the refrigerant exit 2d that the cooling matchmaker is flowed out on vis-a-vis the barrel of downside with this refrigerant inlet 2c, dividing plate 3 is arranged between this refrigerant inlet 2c1 and the refrigerant exit 2d, and be in the position by downside, the edge of its width contacts with the inwall of cylinder shell 2.
Arrow among Fig. 4 is represented the flow direction of refrigerant, as shown in the figure, the refrigerant of gaseous state enters the condensation chamber 2a of housing 2 from the refrigerant inlet 2c that is arranged in housing 2 length direction substantial middle, distinguish two side flow to the left and right afterwards, in condensation chamber 2a with condenser pipe in cooling water generation heat exchange and be condensed, as mentioned above, because the length of rectangular tabular dividing plate 3 is less than the length of housing 2, so form the path that allows refrigerant to pass through by the lengthwise edge of this dividing plate 3 and the inwall of housing 2, be condensed pipe 4 condensations and become liquid refrigerant and flowed to cold chamber 2b from condensation chamber 2a from what refrigerant inlet 2c effluent was come via this path, in crossing cold chamber 2b with supercooling tube 5 in cooling water generation heat exchange and become supercooled state liquid, afterwards from the housing 2 of refrigerant exit 2d outflow condenser 1.
In said process, owing in the housing 2 of condenser 1, be provided with dividing plate 3, by this dividing plate 3 housing 2 inside are divided into condensation chamber 2a and cross cold chamber 2b, the condensation process of refrigerant in condenser 1 with cross cold process and separate and carry out, the bubble of gas-liquid coexistence is blocked by dividing plate 3 among the condensation chamber 2a, being condensed into liquid refrigerant entered cold chamber 2b via the passage of dividing plate 3 both sides and carried out cold therein, so, can improve the efficient that refrigerant is cooled, the condenser pipe that minimizing is provided with in order to obtain required degree of supercooling and the quantity of supercooling tube, the manufacturing cost of having saved condenser.
