And, as the explanation that utilizes Fig. 3 to do, the heat exchanger of intersection fin-tube type is owing to having used the heat-transfer pipe that bends to the U font, in order to make the configuration space difference of heat-transfer pipe, need make the bending radius difference of the heat-transfer pipe that bends to the U font (that is, need to prepare multiple heat-transfer pipe.)。But, in the present embodiment, configuration space by the heat-transfer pipe of adjacency in the heat-transfer pipe that dwindles two U fonts (that is, because the heat-transfer pipe of the U font of adjacency is adjusted to L0, L1, L2) just can not need multiple heat-transfer pipe and only with a kind of heat-transfer pipe formation heat exchanger of U font.
Utilize Fig. 6 that the second embodiment of the present invention is described.Because the basic structure of the air regulator of present embodiment is identical with first embodiment, therefore omitted detailed explanation, only difference is described.
Fig. 6 represents the configuration of heat-transfer pipe of the front face side indoor heat converter of present embodiment.In the front face side indoor heat converter of present embodiment, dispose three biographies heat pipes along the flow direction of air, disposing Floor 12 with the rectangular direction of the flow direction of air.Dotted line among the figure represents that the heat-transfer pipe that is inserted into bends to the part of U font.Here L0 represents the configuration space of the heat-transfer pipe of heat exchanger line part.L1 and L2 represent the configuration space of heat-transfer pipe minimum in the configuration space of heat-transfer pipe of heat exchanger curve part 35 and heat exchanger curve part 36.In the present embodiment, the relation of L0, L1, L2 and first embodiment similarly are shown below.
L1＜L0
L2＜L0
Promptly, because the configuration space of the heat-transfer pipe of the heat exchanger curve part 35,36 that air is accelerated easily is narrower than the configuration space of the heat-transfer pipe of heat exchanger line part 50,51,52, the flowing resistance of heat exchanger curve part 35,36 is relatively big, thereby can suppress the acceleration of the air stream of heat exchanger curve part 35,36.That is, the wind speed profile that can reduce the air by heat exchanger is inhomogeneous, can be with improving energy saving and realizing both effects of quietization.
In the present invention, in first embodiment, the part that bends to the U font of the heat-transfer pipe part of dotted line (among the Fig. 6 draw) is not present in the little part of the configuration space of heat-transfer pipe.But in the present embodiment, the part that bends to the U font of the heat-transfer pipe part of dotted line (among the Fig. 6 draw) is present in the little part of the configuration space of heat-transfer pipe.That is,, reduced the arrangement pitch of heat-transfer pipe by using the bending radius heat-transfer pipe 40 littler of U character segment than other heat-transfer pipes.
