流出側の列を風上側に配置した構成としていた。In other words, when a heat medium such as carbon flows through the heat transfer tubes 2 and the cross flow fan 7 rotates, the heat medium passes between the indoor air passing between the groups of plate fins 1 of the fin-tube separation type heat exchanger 6 and the heat medium. Heat exchange takes place in the room, and cool or warm air is blown into the room. In particular, in order to fully demonstrate its capacity as an indoor heat exchanger for heating, the degree of supercooling of the fluorocarbons flowing out from the heat exchanger, which functions as a condenser, must be high. In order to prevent heat conduction from the heat exchanger tubes 2 to the heat exchanger tubes 2 on the outflow side through the plate fins 1, the heat exchanger is divided into two rows, and the row on the fluorocarbon inflow side is placed on the leeward side, and the row on the fluorocarbon outflow side is placed on the leeward side. The structure was such that it was placed on the windward side.

For this reason, there were problems such as the indoor unit not being able to fit into the cabinet, the distance from the crossflow fan becoming close, increasing the noise level, and condensed water adhering to the plate fins scattering during cooling.

で、この結露水飛散も防止できる。In the above configuration, the fin tube type separation type heat exchanger 6
A pair of heat exchangers separated into an upwind side and a leeward side are held by a gap holding plate 4 provided approximately in the middle of a group of plate fins 1, with the partner heat exchanger tube 2 penetrating through one plate. Therefore, the separation gap between the pairs is fixed and regulated. As a result, each heat exchanger of the pair warps outward,
This prevents the central part from becoming bulged as a whole, making it easier to fit into the cabinet 5, and also keeping the distance between the cross flow fan 7 and the fin tube replacement H-type heat exchanger H6 constant. Therefore, variations in air volume and noise level are also reduced. In addition, the heat exchanger on the leeward side is warped outward, and the plate fins 1 are too close to the cross flow fan 7, and the turbulence of the airflow passing between the plate fins 1 becomes large, causing the plate fins 1 to stick and fall during cooling. However, since the distance between the plate fin 1 and the cross flow fan 7 is kept constant, this scattering of the condensed water can be prevented.

調用室内機を供給できることになる。Effects of the Invention As described above, according to the fin-tube separated heat exchanger of the present invention, a gap retaining plate through which the heat exchanger tube of the other party passes is provided approximately in the middle of the brake fin group of a pair of separated heat exchangers. Therefore, the separation gap between the pair of heat exchangers separated into the windward side and the leeward side is fixed and regulated, and the shape and dimensions are stabilized. As a result, each of the pair of heat exchangers can be prevented from warping outward and having a bulging shape in the center as a whole, which improves the fit in the cabinet and improves manufacturing yield. In addition, since the distance between the crossflow fan and the heat exchanger is kept constant, variations in air volume and noise level are reduced, and it is possible to prevent fin condensation water from scattering during cooling, improving performance and quality. This means that stable indoor units for air conditioning can be supplied.
