CLAIM

1. The ornamental design for a heat exchanger holder, substantially as shown and described.

Description:

FIG. 1 is a front elevational view of a heat exchanger holder, showing our new design;

FIG. 2 is a left side view thereof;

FIG. 3 is a right side view thereof;

FIG. 4 is a rear elevational view thereof;

FIG. 5 is a perspective view thereof;

FIG. 6 is a top plan view thereof;

FIG. 7 is a bottom plan view thereof;

FIG. 8 is a reference cross-sectional view taken along the lines 8-8 in FIG. 6 thereof;

FIG. 9 is an another reference figure thereof; showing a state in which a bent part of a U-shaped heat transfer pipe is inserted into the heat exchanger holder of this design; and,

FIG. 10 is an another reference figure thereof; showing a state in which both a U-shaped heat transfer pipe and a shrinkage-lifting prevention rod are inserted into the heat exchanger holder of this design.

Our heat exchanger holder of this design is used to hold and support a U-shaped heat transfer pipe of a heat exchanger, in which a groove is formed in the top end of a main body of the heat exchanger holder and is used to receive therein a bent part of the U-shaped heat transfer pipe, and holes are formed in the front and rear surfaces of the main body in such a way that the holes diagonally face each other and are used to receive therein a shrinkage-lifting prevention rod used to prevent the U-shaped heat transfer pipe from shrinkage-lifting.

Described in detail, as shown in Reference views FIG. 9 and FIG. 10, the bent part of the U-shaped heat transfer pipe is inserted into the groove of the main body, and the shrinkage-lifting prevention rod is movably and diagonally inserted into the holes of the main body such that the shrinkage-lifting prevention rod passes over the bent part, so the U-shaped heat transfer pipe is held by the heat exchanger holder.

The broken lines shown in FIGS. 8 and 9 are for the purpose of illustrating environmental structure that forms no part of the claimed design.
