Figure 1 and Figure 2 As shown, a heat exchanger support frame 100 is installed at one end of the heat exchanger 200. The heat exchanger support frame 100 may include a support plate 101 and a fixing clip 103. The support plate 101 may have multiple mounting holes 105 for the U-shaped tube 201 of the heat exchanger 200 to pass through.

The hole wall of the mounting hole 105 has an open opening 106 on the side near the bottom of the support plate 101. Thus, in this example, the heat exchanger support frame has an open opening 106 on the hole wall of the mounting hole 105 for fixing the U-shaped tube 201 to drain condensate, preventing condensate from accumulating in the mounting hole 105 and affecting the equipment life.

[0030] In some exemplary embodiments, such as Figure 1 and Figure 2As shown, the heat exchanger 200 may include a heat exchanger body 202 and a U-shaped tube 201 protruding from the heat exchanger body 202. The heat exchanger support frame 100 is installed at one end of the heat exchanger 200. The support plate 101 may include a fixing plate 1011 and a flap 1012.

Both the first mounting holes 1051 and the second mounting holes 1052 are elongated holes extending along a first direction. At least two first mounting holes 1051 are arranged sequentially at intervals along the first direction to form a row of first mounting holes 1051. In this example, three first mounting holes 1051 are arranged sequentially at intervals along the first direction to form a row of first mounting holes 1051, such as the i1th row and the i2th row. The first direction is parallel to the fixing plate 1011. Furthermore, in this example, the support plate 101 has two rows of first mounting holes 1051 arranged along the first direction, namely the i1th row and the i2th row. The two rows of first mounting holes 1051 arranged along the first direction are spaced apart in a second direction, which is parallel to the fixing plate 1011 and perpendicular to the first direction. However, this is not limited to the above. For example, each row of first mounting holes 1051 may have more than three first mounting holes 1051, or the first mounting holes 1051 arranged along the first direction may have one row or more than two rows. The plurality of mounting holes 105 also includes a plurality of second mounting holes 1052, at least two of which are arranged sequentially at intervals along the first direction to form a row of second mounting holes 1052, namely the j1th row of second mounting holes 105. In this example, a row of second mounting holes 1052 has three second mounting holes 1052, but this is not limited to the above. Each row of second mounting holes 1052 may have more than three second mounting holes 1052, or the second mounting holes 1052 arranged along the first direction may have at least two rows of second mounting holes 1052. At least one row of first mounting holes 1051 and at least one row of second mounting holes 1052 are arranged alternately in the second direction. In this example, the second mounting holes 1052 of the j1st row are sandwiched between the first mounting holes 1051 of the i1st row and the first mounting holes 1051 of the i2th row.

[0033] In some exemplary embodiments, such as Figure 2 , Figure 3 and Figure 4As shown, at least two first mounting holes 1051 are arranged at intervals along a third direction to form a row of first mounting holes 1051. The first mounting holes 1051 are elongated holes extending along the third direction. In this example, three first mounting holes 1051 are arranged at intervals along the third direction to form a row of first mounting holes 1051, such as the first mounting holes 1051 in the i3rd row and the first mounting holes 1051 in the i4th row. The third direction is parallel to the fixing plate 1011 and intersects the first direction and the second direction respectively. Moreover, in this example, the support plate 101 has two rows of first mounting holes 1051 arranged along the third direction, namely the first mounting holes 1051 in the i3rd row and the first mounting holes 1051 in the i4th row. The two rows of first mounting holes 1051 arranged along the third direction are spaced apart in the fourth direction, which is parallel to the fixing plate 1011 and perpendicular to the third direction. The plurality of mounting holes 105 also includes a plurality of second mounting holes 1052, each of which is an elongated hole extending along a third direction. At least two of the plurality of second mounting holes 1052 are arranged alternately along the third direction to form a row of second mounting holes 1052, namely the j2nd row of second mounting holes 105. In this example, the j2nd row of second mounting holes 1052 is sandwiched between the i3rd row of first mounting holes 1051 and the i4th row of first mounting holes 1051. Thus, the plurality of first mounting holes 1051 includes a plurality of first mounting holes 1051 arranged along a first direction and a plurality of first mounting holes 1051 arranged along a third direction; the plurality of second mounting holes 1052 includes a plurality of second mounting holes 1052 arranged along a second direction and a plurality of second mounting holes 1052 arranged along a third direction.

[0034] In some exemplary embodiments, such as Figure 2 , Figure 3 and Figure 4 As shown, the fixed plate 1011 has multiple first through holes 1013. The flap 1012 is connected to the fixed plate 1011 on the side away from the heat exchanger in a direction perpendicular to the fixed plate 1011. The flap 1012 extends along the circumferential edge of the first through holes 1013 and forms a second through hole 1014. The first through holes 1013 and the second through holes 1014 are arranged sequentially and connected in a direction perpendicular to the fixed plate 1011. The first through holes 1013 and the second through holes 1014 constitute the mounting hole 105. The bottom of the flap 1012 can be the side of the flap 1012 near the bottom plate 102 in a direction parallel to the fixed plate 1011. The hole wall of the second through hole 1014 formed by the flap 1012 is open at the bottom of the flap 1012, so that the bottom of the flap 1012 forms a hollow structure, that is, the bottom of the flap 1012 is hollow. Thus, the bottom hollow structure forms an open opening 106, which is located on the flap 1012 to open the second through hole 1014. One end of the fixing buckle 103 is connected to the flap 1012, and the other end of the fixing buckle 103 can be used to fix the U-shaped tube.

The first fixing parts 1033 of the multiple flaps 1012 arranged at intervals along the first direction are connected sequentially through the connecting plates 1036 to form a water guide plate 1015 extending along the first direction. For example, the protective parts 1033 of the multiple flaps 1012 corresponding to the first mounting hole 1051 in the i1th row are connected sequentially through the connecting plates 1036 to form a water guide plate 1015, and the protective parts 1033 of the multiple flaps 1012 corresponding to the first mounting hole 1051 in the i2th row are also connected sequentially through the connecting plates 1036 to form another water guide plate 1015. Thus, two water guide plates 1015 are formed, both of which are perpendicular to the fixed plate 1011. The first mounting holes 1051 in the i1th row, the first mounting holes 1051 in the i2th row, and the second mounting holes 1052 in the j1th row are all located between the two water guide plates 1015.
