Abstract
A refrigerant condenser is set so that, if its condensation distance is L, the equivalent diameter of a tube having a linearly configured passage for the purpose of heat exchange is de (each dimension being in units of mm), and the number of times the direction change of the linearly configured passage for the purpose of heat exchange change is N, with de.ltoreq.1.15 and the relationship L=(N+1)W=400+1,180 de to 700+1,180 de satisfied, a high heat exchange efficiency is achieved. In this refrigerant condenser, it is possible to use a single long winding tube.
Claims3
A refrigerant condenser comprising:
- a pair of headers which form an inlet and an outlet for refrigerant, and
- at least one tube which forms an internal passage through which refrigerant is caused to flow, said at least one tube being connected to each header, wherein at least part of said passage forms a linearly configured passage for the purpose of heat exchange,
- wherein said refrigerant condenser has a condensation distance of the refrigerant L (in units of mm) and an equivalent diameter of said passage for the purpose of heat exchange de (in units of mm),
- wherein the equivalent diameter de and the condensation distance L are set so as to satisfy each of the following mutually dependent relationships:
- 0.1.ltoreq.de.ltoreq.0.35;
- L.ltoreq.925;
- and
- 18.7+1560 de .ltoreq.L.ltoreq.50+2,500 de.
