[0013] Figure 1 This is a three-dimensional structural schematic diagram of the present invention;

[0014] Figure 2 This is a structural cross-sectional view of the present invention. Detailed Implementation

[0015] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0016] Example 1. A condensation mixing chamber with water collection capacity, configured as follows: Figure 1 and 2 As shown, it includes a heat exchange core 8. The cold edge inlet of the heat exchange core 8 is connected to an inner cylinder 13 and an outer cylinder 12 (2#) in sequence from the outside to the inside. The cold edge outlet of the heat exchange core 8 is provided with a hot edge outlet end cap 4. The lowest end of the hot edge outlet end cap 4 is provided with a drain outlet 5. The hot edge outlet end cap 4 is also connected to a hot edge outlet connector 6. The inner cylinder 13 is surrounded by an outer cylinder 2 (1#). The outer cylinder 2 (1#) is connected to a bypass connector 3. The outer cylinder 2 (1#) is connected to the inner cylinder 13 through a connecting hole 14.

[0017] The aforementioned inner cylinder 13 is trumpet-shaped, with the smaller end located on the outside.

[0018] The aforementioned connecting holes 14 are distributed circumferentially along the outer wall of the No. 1 outer cylinder 2.

[0019] The aforementioned connecting hole 14 is teardrop-shaped.

[0020] The aforementioned heat exchange core 8 has a heat edge inlet connector 11 and a heat edge inlet end cap 10 connected sequentially from the outside to the inside.

[0021] The aforementioned inner cylinder 13 has its small opening connected to the cold edge inlet interface 1.

[0022] The aforementioned heat exchange core 8 cold side outlet is connected to the cold side outlet flange 7.

[0023] The aforementioned heat exchange core 8 is provided with a mounting base 9.

[0024] Among them, the cold-side inlet interface 1, the 1# outer cylinder 2, the bypass connector 3, the 2# outer cylinder 12 and the inner cylinder 13 together form the cold-side inlet structure. The hot-side outlet end cap 4, the drain port 5 and the hot-side outlet connector 6 are connected to form the hot-side outlet structure. The hot-side inlet end cap 10 and the hot-side inlet connector 11 are connected to form the hot-side inlet structure. The cold-side inlet structure, the hot-side outlet structure, the hot-side inlet structure and the cold-side outlet flange 7 are connected together with the heat exchange core 8 in a cross-shaped manner to form the condensation mixing chamber.

[0025] It should be noted that the heat exchange core 8 is made of layers of baffles, fins and seals, which are then brazed together.

[0026] It should be noted that the gas source flow from the bypass connector 3 is mixed with the cold gas flow from the cold side inlet interface 1 through the partition between the outer cylinder 2 and the inner cylinder 13. This prevents the cold gas from being too cold and causing ice blockage in the heat exchange core 8, thereby reducing the mass and heat transfer efficiency of the condensation mixing chamber.

[0027] It should be noted that the mixed cold gas and the hot gas coming from the hot edge inlet joint 11 undergo mass and heat transfer in the heat exchange core 8.

[0028] It should be noted that the hot gas after passing through the heat exchange core 8 impacts the hot edge outlet head 4 at high speed. The free water in the gas settles under gravity after impacting the cavity wall and is discharged through the drain port 5.

[0029] Furthermore, all structures in the condensation mixing chamber are made of aluminum alloy.

[0030] Furthermore, the various structures of the condensation mixing chamber are welded together using aluminum alloy welding wire.

[0031] Furthermore, HW61-EW heat-resistant and anti-corrosion coating is sprayed onto the indoor and outdoor surfaces of the condensation mixing chamber.

[0032] During operation of the condensation mixing chamber, the cold gas flows through the inner cylinder 13 and mixes with the gas source flow from the bypass connector 3. After passing through the outer cylinder 12 (#2), the cold gas undergoes mass and heat transfer with the hot gas at the heat exchange core 8, and finally exits through the cold-side outlet flange 7. The hot gas flows through the hot-side inlet connector 11 and the hot-side inlet head 10, and undergoes mass and heat transfer with the cold gas in the heat exchange core 8. As the temperature of the hot gas decreases, the saturated vapor content decreases, resulting in the generation of free water. The free water precipitated after mass and heat transfer impacts the wall of the hot-side outlet head 4 with the hot gas under high-speed flow. The free water settles and collects under gravity before being discharged through the drain port 5.

[0033] In summary, this utility model provides a condensation mixing chamber with water collection capacity, including a hot-side outlet end cap 4 for free water separation and a drain outlet 5 for free water discharge. It uses high-speed impact and gravity settling to separate free water in the hot gas flow after heat and mass transfer.
