<P>PROBLEM TO BE SOLVED: To provide a heat exchanger capable of heating an object with high heat-exchange efficiency through the use of a heating medium. <P>SOLUTION: A heat exchanger 1 includes a body 10 having a body 2, a top plate 3, and a bottom plate 4, a plurality of distribution pipes 5 so attached as to penetrate the top and bottom plates, an inflow pipe 6 for discharging a heat medium into the body, and a discharge pipe 7 for discharging the heat medium from the body. Among the plurality of distribution pipes, a pipe arrangement is symmetric between a first area distribution pipe group arranged on one side and a second area distribution pipe group arranged on the other side with respect to a virtual face S1 including a central axis of the body and the center of a discharge port 6a. The pipes in the first area distribution pipe group include a first distribution pipe 5a most adjacent to the discharge port, a second distribution pipe 5b adjacent to the first distribution pipe in a circumferential direction with the central axis of the body as the center, and a third distribution pipe 5c adjacent to the first distribution pipe in a radial direction of the body. A distance from the first distribution pipe to the third distribution pipe is 0.77 to 1.3 times a distance from the first distribution pipe to the second distribution pipe. <P>COPYRIGHT: (C)2013,JPO&INPIT |
