The first baffle 210 is further provided with a first opening, and an upper edge of the first opening is not lower than a highest liquid level of the flash vessel. Alternatively, the first opening may be rectangular.
The upper edge of the first opening is not lower than the highest liquid level of the flash device by arranging the first opening to work in cooperation with the first notch. When the liquid level of the refrigerant in the separation area in the flash evaporator is lower, and simultaneously, when the liquid level of the refrigerant in the separation area in the flash evaporator is lower than the lower edge of the first opening, the refrigerant in the flash evaporator enters the separation area through the first notch; when the liquid level of the refrigerant in the separation zone in the flash tank is high, namely, when the liquid level of the refrigerant in the separation zone in the flash tank is higher than the lower edge of the first opening and is lower than the highest liquid level, the refrigerant liquid in the flash tank can enter the separation zone through the first notch and the first opening. Under both liquid level conditions, with continued reference to the arrows in fig. 1, the refrigerant gas of the flash zone can enter the separation zone through the first opening. In the invention, the first opening is required to be matched with the first notch so that the flash device can meet the liquid level requirements of all working conditions, if the flash device is not provided with the first opening, the height of the first notch is required to be further increased so as to meet the liquid level requirements under all working conditions, but when the height of the first notch is too high, the stability of the liquid level can be influenced when the liquid level is low, the liquid outlet 150 cannot form a stable liquid seal, and the problem that the refrigerant gas possibly flows out from the liquid outlet 150 can be caused.
As an alternative implementation, a second notch is provided between the upper edge of the first baffle 210 and the top of the housing 110 of the flash device according to an embodiment of the present invention.

Further, the size of the first opening can be comprehensively determined according to the refrigerant flow rate, the areas of the first notch and the second notch under all working conditions. For example, the size of the first opening may be adjusted by adjusting the length and width of the first opening.
For example, the first baffle 210 may be a circular plate matched with the housing 110, with an arc portion removed as a first notch at a portion thereof adjacent to the bottom of the housing 110, an arc portion removed as a second notch at a portion thereof adjacent to the top of the housing 110, and a rectangular portion removed as a first opening at a proper position at a center thereof.

Further, the second baffle 220 is connected to the first baffle 210 in a non-horizontal manner, so that the included angle between the corrugated groove and the horizontal plane is 0 ° to 30 °, that is, the included angle α between the second baffle 220 and the first baffle 210 is 60 ° to 90 °, and the refrigerant liquid collected in the corrugated groove can be timely discharged from the corrugated groove through the non-horizontal arrangement of the second baffle 220. For example, the second baffle 220 is connected to the first baffle 210 and is inclined downwardly at 15 ° in a horizontal plane, and the corrugation groove is provided at the second baffle 220 in an inclined direction, and the refrigerant gas collides with the second baffle 220 and the top of the housing 110 above the second baffle 220 before passing through the second gap, so that the refrigerant liquid entrained therein is separated and collected in the corrugation groove at the second baffle 220, and at the same time, the collected refrigerant liquid flows down in an inclined direction of the corrugation groove due to the corrugation groove being inclined downwardly at 15 ° with respect to the horizontal plane.
As an alternative implementation, referring to fig. 1 and fig. 4, the flash device according to an embodiment of the present invention is further provided with a third baffle 230, the third baffle 230 divides the separation area into an upper separation area and a lower separation area, a connection between the third baffle 230 and the first baffle 210 is located between the first opening and the second gap, and a first through hole 231 is formed in the third baffle 230.

With continued reference to fig. 1, the dotted line indicates the liquid level of the refrigerant in the flash evaporator, and since part of the refrigerant gas in the flash evaporator directly enters the lower separation zone through the first opening and the lower separation zone is closer to the liquid level of the refrigerant, more refrigerant liquid is entrained in the refrigerant gas entering the lower separation zone through the first opening, and the liquid entrained in the refrigerant gas in the lower separation zone can be effectively separated by the treatment of the third baffle 230 provided with the first through hole 231, the separated refrigerant gas enters the upper separation zone, and the amount of the refrigerant liquid entrained in the refrigerant gas entering the upper separation zone can be effectively reduced.
As an alternative implementation, referring to fig. 1, 5 and 6, the flash device according to an embodiment of the present invention is further provided with a fourth baffle 240 and a fifth baffle 250, the fourth baffle 240 is located between the first baffle 210 and the air compensating port 160, the fifth baffle 250 is located between the third baffle 230 and the air compensating port 160, and one side of the fourth baffle 240 is connected to one side of the fifth baffle 250, so as to jointly partition the upper separation area into a first upper separation area and a second upper separation area.

The refrigerant gas enters the second upper separation zone after being further processed by the fifth baffle 250, so that the gas-liquid separation efficiency of the refrigerant gas entering the second upper separation zone is further improved, and the liquid carrying amount of the refrigerant gas entering the second upper separation zone is reduced.
As an alternative embodiment, referring to fig. 1, 7 and 8, the flash device according to an embodiment of the present invention further includes a filter assembly 270, where the filter assembly 270 is disposed in the first upper separation region and between the fifth baffle 250 and the air compensating port 160. The refrigerant gas entering the first upper separation zone is further filtered by the filter screen assembly 270 and then discharged out of the flash evaporator through the air supplementing port 160, so that the gas-liquid separation efficiency of the flash evaporator is further improved, and the refrigerant gas discharged out of the flash evaporator is further ensured to be free of liquid. Optionally, the filter assembly 270 has a rectangular shape, one side of the filter assembly 270 is connected to the fourth baffle 240, and the other sides are connected to the housing 110 and the second seal head 130, respectively.
Optionally, filter assembly 270 includes a gas-liquid filter 274 and a frame 271. Wherein, the gas-liquid filter 274 is rectangular, and four sides of the rectangular gas-liquid filter 274 are shaped by the frame 271. Further, the stainless steel wire mesh 273 is provided on both sides of the gas-liquid filter 274, and the stainless steel wire mesh 273 can enhance the strength of the gas-liquid filter 274, thereby avoiding deformation of the gas-liquid filter 274 caused by the directional flow of the refrigerant gas through the gas-liquid filter 274. Further, the filter assembly 270 is further provided with a plurality of pressing strips 272, and two ends of the pressing strips 272 are respectively fixed on the frame 271, so as to further enhance the strength of the filter assembly 270.
Further alternatively, the second through hole 251 has a diameter equal to or larger than that of the first through hole 231. Since the refrigerant gas entering the first upper separation zone is partially separated from the refrigerant liquid by the second baffle 220 or partially separated from the refrigerant liquid by the third baffle 230, the entrained refrigerant liquid content of the refrigerant gas entering the first upper separation zone is reduced, and the droplets of the entrained refrigerant liquid are smaller, so that the diameter of the second through hole 251 is not excessively large; in addition, in order to control the flow rate of the refrigerant gas flowing through the filter assembly 270 to be in the optimal range, the filter assembly has a high separation efficiency, and therefore the diameter of the second through hole 251 is not too small, so that the diameter of the second through hole 251 is larger than the diameter of the Deng Yidi through hole 231, and the flow rate of the refrigerant gas flowing through the filter assembly 270 can be in the optimal range.
