As shown in fig. 1 and 2, in order to secure the effect of filtering the frozen oil, the oil separating assembly includes a gas equalizing structure, a baffle 34, a first fixing plate 35, a gas-liquid filter screen 37, a second fixing plate 36, and the like.
Alternatively, as shown in fig. 11 to 13, the oil separation housing includes two side plates 41 and a bottom plate 42, the side plates 41 being provided at intervals from each other, the opening 411 being provided on the side plate 41, the bottom plate 42 being connected between the two side plates 41. The side plate 41 and the bottom plate 42 enclose a separate chamber. The side plates 41 and the bottom plate 42 may have the same length as the cylinder 1, so that the separation chamber can be separated from the heat exchange chamber of the cylinder 1 by only providing the side plates 41 and the bottom plate 42, and the two are communicated only through the opening 411 provided in the side plate 41.

As shown in fig. 15 to 23, the intake pipe 2 may be a straight pipe type, a reduced-mouth type, or a flared-mouth type. As shown in fig. 15 and 16, the cross-sectional area of the straight pipe type air inlet pipe 2 is unchanged, and the air inlet pipe 2 has a simple structure and is convenient to process and install. The necking type air inlet pipe 2 means that the cross section area of the air inlet pipe 2 is gradually reduced at an air outlet, and the air outlet flow speed of the air inlet pipe 2 is higher. The flaring type air inlet pipe 2 is arranged at the air outlet, the cross section area of the air inlet pipe 2 is gradually increased, the area of the air outlet of the air inlet pipe 2 is larger, the air outlet surface is larger, and the uniform air outlet of the air is facilitated.

Optionally, the air equalizing structure includes a first air baffle 31, a second air baffle 32, and an air equalizing plate 33.
As shown in fig. 7 and 8, the first air baffle 31 is provided with a first mounting through hole 311, and the intake pipe 2 passes through the first air baffle 31 through the first mounting through hole 311. The first air baffle 31 may be an arc-shaped plate, or may be a flat plate or other shape.
The number of the second air baffle plates 32 is two, one second air baffle plate 32 is connected to the first end of the first air baffle plate 31, and the other second air baffle plate 32 is connected to the second end of the first air baffle plate 31. It should be noted that, the second air baffle 32 may be integrally formed with the first air baffle 31, for example, by bending, injection molding, or the like; it may also be formed by machining, such as welding, separately from the first air baffle 31.
The air equalization board 33 is connected at the one end that keeps away from first air baffle 31 of second air baffle 32, and air equalization hole 332 sets up on air equalization board 33, and first air baffle 31, second air baffle 32 and air equalization board 33 enclose into the air equalization chamber.
In the present embodiment, a ventilation passage is provided between the second air baffle 32 and the oil separation housing, so that the air flow flowing out from the air-equalizing chamber can continue to move upward.
As shown in fig. 6, the two opposite edges of the air equalizing plate 33 are provided with air equalizing openings 331, and the air equalizing openings 331 can better pass through air flow, so that flow resistance can be reduced. The gas-equalizing plate 33 can uniformly flow the gas to ensure the treatment effect, and can remove a part of the liquid droplets to realize the gas-liquid separation effect.
Alternatively, as shown in fig. 4, 24-27, the cross-sectional shape of the gas-equalizing plate 33 is corrugated. The corrugated gas-equalizing plate 33 facilitates the convergence and falling of the droplets adhering thereto. As shown in fig. 24, the gas-equalizing plate 33 may be a corrugated plate, that is, the cross section of the gas-equalizing plate 33 is formed by sequentially connecting a plurality of arc segments to form a sine wave-like pattern. As shown in fig. 25, the gas-equalizing plate 33 may be an arch-shaped corrugated plate, that is, the cross section of the gas-equalizing plate 33 is composed of a plurality of circular arcs opened downward, and two adjacent circular arcs are connected by a straight line segment. As shown in fig. 26, the gas-equalizing plate 33 may be a toothed corrugated plate, that is, the cross section of the gas-equalizing plate 33 is composed of a plurality of trapezoid segments, and two adjacent trapezoid segments are connected by a straight segment.

As shown in fig. 14, the baffle 34 serves to divert the gas flow, prevent the gas flow from climbing the wall (gathering and moving upward along the inner wall of the oil separation housing), and make the gas flow path longer, thereby ensuring the gas-liquid separation effect. The baffle plate 34 may be provided with a baffle vent hole 341 so that a part of the air flow passes through the baffle vent hole 341 and another part of the air flow passes through a gap between the baffle plate 34 and the air inlet pipe 2.
Optionally, the baffle 34 is two and located on both sides of the air inlet pipe 2, which can make the air flow more uniform.
Optionally, the cross-sectional shape of baffle 34 is corrugated, which increases the contact area with the gas flow and improves the treatment. The corrugated shape of the baffle 34 may be the same as or different from the corrugated shape of the gas-equalizing plate 33.

The first fixing plate 35 may be a flat plate, an arc-shaped plate, or a corrugated plate, and may be the same corrugated plate as the gas equalization plate 33 or may be a different corrugated plate.
In the present embodiment, the oil separation assembly further includes a gas-liquid filter screen 37, and the gas-liquid filter screen 37 is disposed above the first fixing plate 35. The gas-liquid filter screen 37 is used for filtering oil.

The novel built-in oil separator structure is adopted in the heat exchanger shell pipe of the embodiment, and the oil separator structure is simplified under the condition that the oil-gas separation effect is unchanged.
The oil separation part is internally provided with a heat exchanger. The condenser is taken as an example, wherein the oil separation part is arranged in the condenser, the empty space in the horizontal shell-and-tube condenser is reasonably utilized, the space volume occupied by the whole machine is reduced, the whole machine is simple in appearance and more integrated, the structure is simpler than that of an independent oil separator, and the effect is reliable.
The oil separation housing of the oil separation portion adopts a U-shaped appearance, the bottom plate 42 and the two side plates 41 of the U-shaped structure are easy to process, and welding between the side plates 41 and the bottom plate 42 is easier. When the fluid flows through the bottom, the fluid flows upwards along the wall of the U-shaped bottom plate 42, no great loss is generated in the flowing process, the reduction of the pressure drop of the fluid is reduced, the separation area of the built-in oil is increased, and the separation capacity of the device is increased.
