[0037] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0038] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0039] like Figure 1 As shown, according to the distributor for the full liquid evaporator 10 of the embodiment of the utility model, the distributor includes a liquid equalizing plate 110, and the liquid equalizing plate 110 includes a liquid inlet area 111 and a liquid outlet area 112, the liquid inlet area 111 is used to be opposite to the liquid inlet 120 of the full liquid evaporator 10, and the liquid outlet area 112 has a plurality of liquid outlet holes 1101, and the plurality of liquid outlet holes 1101 are arranged non-uniformly in the flow direction, wherein the flow direction is configured to be away from the liquid inlet area 111, and the refrigerant can enter the full liquid evaporator 10 through the liquid inlet 120. Since the liquid inlet area 111 is opposite to the liquid inlet 120, And no liquid outlet hole is set, the refrigerant will flow into the liquid outlet area 112 of the liquid equalizing plate 110, and be sent to the inner cavity of the full liquid evaporator 10 from the liquid outlet hole 1101 in the liquid outlet area 112. In the process of the refrigerant flowing away from the liquid outlet area 112, the flow rate and flow velocity at different positions of the liquid outlet area 112 are different. The multiple liquid outlet holes 1101 are arranged non-uniformly, and the arrangement density of the liquid outlet holes 1101 at different positions of the liquid outlet area 112 is different. The refrigerant flow rate and refrigerant flow velocity in different areas of the liquid outlet area 112 can be controlled, so that the liquid level height at different positions in the full liquid evaporator 10 can be uniform.

[0040] According to the distributor for the fully liquid evaporator 10 of the embodiment of the utility model, the liquid outlet holes 1101 are non-uniformly arranged in the flow direction of the liquid equalizing plate 110, so as to adjust the liquid outlet flow rate of the liquid outlet area 112 at different positions in the flow direction, so that the liquid outlet flow rate of the refrigerant at different positions along the flow direction of the liquid outlet area 112 of the liquid equalizing plate is evenly distributed, thereby avoiding the liquid level of the refrigerant in the fully liquid evaporator 10 being locally too high or locally too low along the flow direction.

[0041] like Figure 2As shown, in some embodiments of the present invention, the liquid outlet area 112 includes a first area 1121 and a second area 1122, the second area 1122 is farther away from the liquid inlet area 111 than the first area 1121, the first area 1121 and the second area 1122 are both provided with at least two liquid outlet holes 1101, and the arrangement density of the liquid outlet holes 1101 in the first area 1121 is different from the arrangement density of the liquid outlet holes 1101 in the second area 1122, wherein the arrangement density of the liquid outlet holes 1101 refers to the number of liquid outlet holes 1101 arranged per unit length or unit area. It can be understood that the dynamic pressure of the refrigerant in the equalizing plate increases with the increase of flow rate, and the static pressure decreases with the increase of dynamic pressure. The liquid outlet flow rates of the refrigerant in the first zone 1121 and the second zone 1122 are different. By setting liquid outlet holes 1101 of different densities according to the flow characteristics of the refrigerant in the first zone 1121 and the second zone 1122, the number of liquid outlet holes 1101 in the equalizing plate 110 in the first zone 1121 and the second zone 1122 can be adjusted, thereby adjusting the liquid outlet flow rate or flow rate in the first zone 1121 and the second zone 1122. For example, the arrangement density of the liquid outlet holes 1101 in the first zone is greater than the arrangement density of the liquid outlet holes 1101 in the second zone, which can balance the liquid level in the fully liquid evaporator and avoid the liquid level in the flow direction being too high or too low locally after the refrigerant enters the fully liquid evaporator 10 in the first zone 1121 and the second zone 1122; or, the arrangement density of the liquid outlet holes 1101 in the first zone is less than the arrangement density of the liquid outlet holes 1101 in the second zone, which can balance the refrigerant flow rate at various locations in the fully liquid evaporator.

[0042] Regarding the arrangement of the liquid outlet holes 1101 in the first area 1121 and the second area 1122 , the present invention may include but is not limited to the following multiple implementations.

[0043] In a first implementation manner, the number of liquid outlet holes 1101 per unit area in the first zone 1121 is different from the number of liquid outlet holes 1101 per unit area in the second zone 1122 .

[0044] In the second implementation, Figure 2 As shown, the distance L1 between adjacent liquid outlet holes 1101 in the first zone 1121 in the flow direction is different from the distance L2 between adjacent liquid outlet holes 1101 in the second zone 1122 in the flow direction.

[0045] For example, the liquid balancing plate 110 can be configured as a long strip plate, and the flow direction is a direction away from the liquid inlet area 111 in the length direction of the liquid balancing plate 110, wherein the first area 1121 and the second area 1122 are configured to be arranged along the length direction of the liquid balancing plate 110, and the first area 1121 is closer to the liquid inlet area 111 than the second area 1122, wherein the first area 1121 and the second area 1122 can be arranged on the same side of the liquid inlet area 111 in the flow direction, and the liquid inlet area 111, the first area 1121 and the second area 1122 are arranged sequentially in the flow direction. In addition, the first area 1121 and the second area 1122 can also be arranged on different sides of the liquid inlet area 111 in the flow direction.

[0046] In some examples, the first zone 1121 may have at least two liquid outlet holes 1101 in the flow direction, and the spacing between adjacent liquid outlet holes 1101 may be L1; the second zone 1122 may have at least two liquid outlet holes 1101 in the flow direction, and the spacing between adjacent liquid outlet holes 1101 may be L2, where L1 is different from L2.

[0047] In other examples, the first zone 1121 may have more than three liquid outlet holes 1101 in the flow direction, each adjacent liquid outlet hole 1101 has a first spacing between them, and the multiple first spacings may be the same or different; the second zone 1122 may have more than three liquid outlet holes 1101 in the flow direction, each adjacent liquid outlet hole 1101 has a second spacing between them, and the multiple second spacings may be the same or different.

[0048] In a third implementation, a spacing L1 between adjacent liquid outlet holes 1101 in the first zone 1121 in the flow direction is different from a spacing L2 between adjacent liquid outlet holes 1101 in the second zone 1122 in the flow direction, and the spacing L1 is smaller than the spacing L2.

[0049] It can be understood that compared with the second zone 1122 far away from the liquid inlet zone 111, the flow rate of the refrigerant in the first zone 1121 is larger, so the static pressure of the refrigerant in the first zone 1121 is smaller than the static pressure of the refrigerant in the second zone 1122. At this time, the liquid outlet flow rate of the liquid outlet hole 1101 arranged in the first zone 1121 is smaller than the liquid outlet flow rate of the liquid outlet hole 1101 arranged in the second zone 1122. The spacing L1 of the first zone 1121 is set to be smaller than the spacing L2 of the second zone 1122. The arrangement density of the liquid outlet holes 1101 in the first zone 1121 can be set to be greater than the arrangement density of the liquid outlet holes 1101 in the second zone 1122, thereby adjusting the liquid outlet flow rate of the first zone 1121 and the liquid outlet flow rate of the second zone 1122 to avoid the liquid level in the full liquid evaporator 10 being locally too high or locally too low in the flow direction after the refrigerant is discharged from the first zone 1121 and the second zone 1122.

[0050] In the fourth implementation, the spacing between adjacent liquid outlets 1101 in the flow direction gradually increases. For example, there are the first liquid outlet, the second, the third and the fourth in the flow direction, the first liquid outlet, the second, the third and the fourth are arranged adjacently and gradually away from the liquid inlet area, the spacing between the first and the second is a1, the spacing between the second and the third is a2, and the spacing between the third and the fourth is a3, wherein a1<a2<a3. It should be noted that the above examples are only some implementation methods of the utility model, and are not intended to limit the protection scope of the utility model.

[0051] It can be understood that the refrigerant flow rate in the circulation direction gradually decreases, the static pressure gradually increases, the liquid flow rate of the liquid outlet holes 1101 in the circulation direction increases, and when the spacing between adjacent liquid outlet holes 1101 is the same, the liquid flow rate of the partial liquid outlet area 112 close to the liquid inlet area 111 is less than the liquid flow rate of the partial liquid outlet area 112 far from the liquid inlet area 111. The spacing between adjacent liquid outlet holes 1101 in the circulation direction is adjusted to gradually increase, so that the distribution of the liquid outlet holes 1101 in the liquid outlet area 112 in the circulation direction is first dense and then sparse, and the liquid flow rate of the partial liquid outlet area 112 close to the liquid inlet area 111 is increased while the liquid flow rate of the partial liquid outlet area 112 far from the liquid inlet area 111 is reduced, and the liquid flow rate at different positions of the liquid outlet area 112 is adjusted to achieve that the liquid level in the circulation direction is maintained at the same horizontal height after the refrigerant enters the full liquid evaporator 10 from the liquid outlet area 112.

[0052] In addition, in combination with the above implementation, in some embodiments of the present invention, the diameter of the liquid outlet hole 1101 is not less than 5 mm and not more than 10 mm. For example, the diameter of the liquid outlet hole 1101 can be set to 5 mm, 6.2 mm, 8.5 mm or 9.5 mm.

[0053] In some embodiments of the present invention, the ratio of the spacing L1 to the aperture of the liquid outlet hole 1101 is not less than 1 and not greater than 3, and the ratio of the spacing L2 to the aperture of the liquid outlet hole 1101 is not less than 1 and not greater than 5.

[0054] In other embodiments of the present invention, the spacing L1 can be set to be not less than 5 mm and not more than 20 mm, and the spacing L2 can be not less than 5 mm and not more than 50 mm. For example, the spacing L1 can be set to 5 mm, 10 mm, 15 mm or 20 mm, and the spacing L2 can be set to 5 mm, 15 mm, 20 mm or 50 mm. Of course, the above parameters are only some embodiments of the present invention and are not intended to limit the scope of protection of the present invention.

[0055] In some embodiments of the present invention, the ratio of the distance between adjacent liquid outlet holes 1101 in the flow direction to the aperture of the liquid outlet hole 1101 is not less than 1 and not greater than 5.

[0056] In some embodiments of the present invention, the distance between adjacent liquid outlet holes 1101 in the flow direction is not less than 5 mm and not more than 50 mm, for example, 5 mm, 10 mm, 15 mm, 25 mm, 35 mm or 50 mm. Of course, the above parameters are only some embodiments of the present invention and are not intended to limit the scope of protection of the present invention.

[0057] In some embodiments, the spacing between adjacent liquid outlet holes 1101 in the flow direction gradually increases, and the spacing between adjacent liquid outlet holes 1101 is not less than 5 mm and not more than 50 mm. For example, the first liquid outlet hole, the second, the third and the fourth liquid outlet holes are arranged adjacently in the flow direction gradually away from the liquid inlet area, the spacing between the first and the second is set to 5 mm, the spacing between the second and the third is set to 13 mm, and the spacing between the third and the fourth is set to 25 mm. Of course, the above parameters are only some embodiments of the utility model, and are not intended to limit the scope of protection of the utility model.

[0058] Combination Figure 3 and Figure 4 In some embodiments of the present invention, the liquid equalizing plate 110 includes a top plate 113 and a side plate 114, the top plate 113 extends along a first direction, the side plate 114 is connected to at least one of the two side edges of the top plate 113 opposite to each other along a second direction, and extends along the side edges, and a guide groove 115 is defined between the side plate 114 and the top plate 113.

[0059] The "first direction" may be the length direction of the liquid balancing plate 110, or may refer to the left-right direction in the figure, and the "second direction" may be the width direction of the liquid balancing plate 110, or may refer to the front-back direction in the figure. Of course, these descriptions of orientations do not constitute a limitation on the protection scope of the present utility model, but are merely descriptions made in accordance with the drawings of the present application. When the liquid balancing plate 110 or the full liquid evaporator 10 including the liquid balancing plate 110 is placed in a different manner, the descriptions of the above orientations need to be adjusted accordingly.

[0060] like Figure 3 As shown, in some embodiments of the present invention, a plurality of liquid outlets 1101 are disposed on the side plate 114 .

[0061] It can be understood that the side plate 114 is connected to the top plate 113, and together with the top plate 113, constructs a guide groove 115 for the refrigerant to flow from the liquid inlet area 111 through the liquid outlet area 112. The refrigerant flows from the guide groove 115 through the liquid outlet hole 1101 provided in the liquid outlet area 112, thereby achieving uniform distribution of the refrigerant.

[0062] It can also be understood that the heat exchange tube is located above the top plate 113, and the liquid outlet 1101 is provided on the side plate 114. The liquid outlet 1101 is not opposite to the heat exchange tube, so as to prevent the refrigerant from being directly sprayed from the liquid outlet 1101 to the surface of the heat exchanger, causing local droplet accumulation and retention on the heat exchange tube and causing corrosion to the heat exchange tube. At the same time, when the refrigerant is discharged through the liquid outlet 1101 of the side plate 114 of the liquid balancing plate 110, it is first evenly sprinkled on the shell 12 of the full liquid evaporator 10, and then contacts the surface of the heat exchanger as the liquid level rises, so that the surface of the heat exchanger is fully moistened, thereby improving the heat exchange efficiency.

[0063] In some embodiments of the present invention, the liquid inlet area 111 includes a first portion, which is disposed on the top plate 113 and is opposite to the liquid inlet 120 of the flooded evaporator 10 .

[0064] It is understandable that the first part is arranged on the top plate 113 and opposite to the liquid inlet 120 to prevent the refrigerant from directly spraying onto the surface of the heat exchanger after entering the liquid inlet area 111 and causing local droplet accumulation and retention on the heat exchange tubes, thereby causing corrosion to the heat exchange tubes.

[0065] In other embodiments of the present invention, the liquid inlet area 111 includes a first part and a second part, the first part is arranged on the top plate 113 and opposite to the liquid inlet 120 of the full liquid evaporator 10, and the second part is arranged on the side plate 114 and opposite to the first part along the second direction.

[0066] It can be understood that the flow rate of the refrigerant entering the liquid inlet area 111 is relatively fast, and the first part and the second part surround the liquid inlet and outlet area 111 and prevent the refrigerant from directly entering the full liquid evaporator 10 from the liquid inlet area 111 without passing through the liquid outlet area 112, affecting the liquid level height of the refrigerant in the full liquid evaporator 10 relative to the liquid inlet area 111. At the same time, the refrigerant flows through the liquid inlet area 111 to the liquid outlet area 112 and then passes through the liquid outlet hole 1101, preventing the refrigerant with a higher flow rate from directly impacting the liquid outlet hole 1101, thereby reducing the risk of clogging and damage to the liquid outlet hole 1101.

[0067] like Figure 3 As shown, in some embodiments of the present invention, the liquid balancing plate 110 further includes a sealing plate 116 , which is connected to both ends of the top plate 113 along the first direction and closes both ends of the guide groove 115 .

[0068] It can be understood that the sealing plate 116 closes the two ends of the guide groove 115 and is connected to the liquid equalizing plate 110, preventing the refrigerant from entering the fully liquid evaporator 10 through the two ends of the guide groove 115 or the gap between the top plate 113 and the sealing plate 116, thereby affecting the liquid level height of the refrigerant in the fully liquid evaporator 10 relative to the liquid inlet area 111.

[0069] In some embodiments of the present invention, the side edge of the sealing plate 116 facing away from the top plate 113 is configured to be adapted to the arc shape of the outer shell 12 of the flooded evaporator 10 .

[0070] It can be understood that the arc shape of the distributor fits with the outer shell 12 of the full liquid evaporator 10, which makes it convenient for the distributor and the full liquid evaporator 10 to be arranged at positions compatible with the outer shell 12 of the full liquid evaporator 10, and at the same time facilitates the arc shape to be connected to the full liquid evaporator 10 by welding or other fixed connection methods.

[0071] In addition, the full liquid evaporator 10 of the utility model may include a liquid balancing plate 110 and a shell 12, wherein the liquid balancing plate 110 may be arranged inside the shell 12 and located at the lower part of the shell 12, and a liquid inlet cavity is constructed between the liquid balancing plate 110 and the bottom wall of the shell 12, and a liquid inlet is provided on the bottom wall of the shell 12, and the liquid inlet is connected to the liquid inlet cavity for liquid inlet. The top plate of the liquid balancing plate is opposite to the bottom wall of the shell 12 in the up-down direction, the lower edge of the side plate of the liquid balancing plate may be connected to the bottom wall of the shell, and the lower edge of the sealing plate 116 of the liquid balancing plate may be connected to the bottom wall of the shell, thereby constructing a relatively closed space between the liquid balancing plate and the bottom wall of the shell. The sealing plate may be welded to the shell or connected in other ways, and the side plate may be welded to the shell or connected in other ways.

[0072] In the present invention, the arrangement of the liquid inlet area 111 and the liquid outlet area 112 on the liquid balancing plate 110 includes but is not limited to the following arrangement forms.

[0073] like Figure 1 As shown, in some embodiments of the present invention, the liquid balancing plate 110 extends along the first direction, and the middle area along the first direction forms a liquid inlet area 111, and the parts on both sides of the liquid inlet area 111 in the first direction respectively form liquid outlet areas 112. Figure 1 The middle area of ​​the liquid balancing plate 110 is configured as a liquid inlet area 111, and the left and right halves of the liquid balancing plate 110 are respectively configured as liquid outlet areas 112. For the liquid outlet area 112 located on the left side of the liquid inlet area 111, the direction from the middle area to the left is configured as its flow direction; for the liquid outlet area 112 located on the right side of the liquid inlet area 111, the direction from the middle area to the right is configured as its flow direction.

[0074] It can be understood that the refrigerant enters the liquid inlet area 111 from the middle of the liquid equalizing plate 110, and flows along the first direction to the liquid outlet areas 112 on both sides. Multiple liquid outlet holes 1101 are set in the liquid outlet areas 112 on both sides to adjust the liquid outlet flow rate at different positions of the liquid equalizing plate 110. The liquid outlet flow rates of the liquid outlet areas 112 on both sides are adjusted at the same time, thereby improving the working efficiency of the distributor to evenly distribute the refrigerant.

[0075] like Figure 5 and Figure 6 In some other embodiments of the present invention, the liquid balancing plate 110 is configured with a liquid inlet area 111, and a liquid outlet area 112 is configured on one side of the liquid inlet area 111. Figure 5 , the liquid inlet area 111 can be set at the right end of the liquid balancing plate 110, and the portion of the liquid balancing plate 110 located on the left side of the right end of the liquid balancing plate 110 is set as the liquid outlet area 112, wherein the flow direction is from right to left. Figure 6 The liquid inlet area 111 can also be set at the two ends of the liquid equalizing plate 110, and the area between the liquid inlet areas 111 at both ends of the liquid equalizing plate 110 is set as the liquid outlet area 112, wherein the left half of the area between the liquid inlet areas 111 at both ends of the liquid equalizing plate 110 is constructed as the liquid outlet area corresponding to the left liquid inlet area 111, and the flow direction is from left to right; the right half of the area between the liquid inlet areas 111 at both ends of the liquid equalizing plate 110 is constructed as the liquid outlet area corresponding to the right liquid inlet area 111, and the flow direction is from right to left.

[0076] In addition, in some other embodiments of the present invention, the liquid inlet area 111 and the liquid outlet area 112 on the liquid equalizing plate 110 are arranged alternately.

[0077] The present utility model further provides a liquid-filled evaporator 10 . The liquid-filled evaporator 10 according to the present utility model is briefly described below.

[0078] like Figure 7 As shown, the full liquid evaporator 10 according to the embodiment of the utility model comprises a housing 12 and a distributor 11 for the full liquid evaporator 10 according to the above embodiment, combined with Figure 8 The bottom wall of the shell 12 is provided with a liquid inlet 120, the distributor 11 is arranged in the lower part of the shell 12, and a liquid inlet cavity connected to the liquid inlet 120 is formed between the distributor 11 and the bottom wall of the shell 12, and the liquid inlet area 111 is opposite to the liquid inlet 120.
