Description

Technical Field

[0001] This utility model relates to the field of heat dissipation technology, and in particular to a heat exchanger. Background Technology

[0002] In existing refrigeration equipment, the heat exchanger is the main refrigeration component. A heat exchanger assembly typically includes fins and a heat exchange coil. The heat exchange coil consists of sequentially connected straight sections and curved sections. The straight sections usually extend horizontally and are arranged in a rectangular pattern, while the fins are arranged vertically and fitted onto the straight sections. This structural design reduces the total heat exchange area of ​​the fins, and the heat exchange area of ​​the heat exchange coil is also limited, resulting in lower heat exchange efficiency and consequently lower output cooling capacity efficiency.

[0003] During heat exchanger installation, the heat exchange coils and fins are prone to collisions. After installation, they may also bump into other components in the cabinet, damaging the heat exchanger and affecting its heat exchange efficiency and lifespan. Furthermore, during transportation, they may be subjected to significant impacts, leading to damage to the heat exchange coils and fins. Replacing damaged parts is inconvenient, time-consuming, and labor-intensive.

[0004] Therefore, it is necessary to provide a heat exchanger that overcomes the defects mentioned above. Utility Model Content

[0038] See Figure 4 and Figure 6The protective frame assembly 2 includes a first protective frame 21 and a second protective frame 22. The first protective frame 21 is fixed to the first side portion 12, and the second protective frame 22 is fixed to the second side portion 13. The first protective frame 21 includes a front baffle 211 and a first support frame 212 and a second support frame 213 extending from the front baffle 211 toward the side where the housing 1 is located. The first support frame 212 and the second support frame 213 are vertically corresponding. The first support frame 212 includes two horizontally extending arms 2121 extending from the front baffle 211 toward the side where the housing 1 is located, and a cross arm 2122 connecting the ends of the two arms 2121. The two arms 2121 and the cross arm 2122 form a hollow frame shape.

[0039] The horizontal arm 2122 is provided with vertically extending mounting buckles 5 at intervals. In this embodiment, there are two mounting buckles 5 on the horizontal arm 2122, one located on the left and the other on the right. The first side 12 is provided with a locking slot 6 corresponding to the mounting buckle 5. The mounting buckle 5 can be engaged with the locking slot 6 to complete the installation and fixation of the two.

[0040] See Figure 6 The second support frame 213 extends horizontally from the front baffle 211 toward the side where the housing 1 is located in a grid-like shape. The end of the second support frame 213 is bent upward and has a first flange 2131 for fixing to the front plate 114. The first flange 2131 has fixing holes and is fixedly connected to the front plate 114 by bolts after being attached to it.

[0041] See Figure 7 The second protective frame 22 includes a rear baffle 221 and a third support frame 222 and a fourth support frame 223 extending from the rear baffle 221 toward the side where the housing 1 is located.
