The flow distribution pipes are exposed through the flow distribution holes and the exposed heights of the flow distribution pipes are the same. Because the tube heads of the flow distribution tubes connected with the flow distribution holes of the liquid distribution disc are exposed to the same height, the liquid flowing into the flow distribution tubes through the tube openings is uniform and consistent, so that the distribution uniformity of the liquid distributor is greatly improved, and the requirements of improving the product quality and improving the production efficiency are met. As disclosed in the chinese patent application with application No. 201810879931.1 (application publication No. CN 108917232A), the liquid distributor includes an upper sealing plate and a lower housing, the upper sealing plate is disposed on the upper portion of the lower housing and encloses a liquid distribution chamber together with the lower housing, the edge of the lower housing is bent toward the outside of the liquid distribution chamber to form a first bending portion, and the first bending portion is riveted with the upper sealing plate.

SUMMERY OF THE UTILITY MODEL

The first technical problem to be solved by the present invention is to provide a liquid distributor with simple structure and uniform water outlet, aiming at the current situation of the prior art.

The second technical problem to be solved by the present invention is to provide a condenser heat dissipation structure with a liquid distributor, which has a good heat dissipation effect.

The technical scheme adopted by the utility model for solving the first technical problem is as follows: this liquid distributor, including casing and the apron of assembly on the casing, the apron encloses into the cloth liquid chamber with the casing jointly, still including with inlet and liquid outlet that the cloth liquid chamber is linked together, its characterized in that: be formed with on casing or the apron with the inlet channel that the inlet is linked together, inlet channel's inner wall surface is unevenness's coarse structure, inlet channel's inside wall top extends and forms the baffle to the lateral buckling at liquid outlet place, the liquid outlet is located go up the below of baffle.

Preferably, the surface roughness Ra of the inner wall of the liquid inlet channel is more than or equal to 1.6 microns. The larger the roughness, the more obvious the blocking effect on the water flow.

In order to further block the water flow flowing into the liquid inlet channel, a water blocking piece is installed in the liquid inlet channel.

The water retaining piece can have various different structures, and preferably, the water retaining piece is a water retaining rib distributed at intervals along the water flow direction of the liquid inlet channel. The water retaining rib plays a role in slowing down water flow, impact of water flow on the rear wall of the downstream end of the liquid inlet channel is reduced, the rear end of the liquid inlet channel, namely the overflow amount of the downstream end is effectively reduced, correspondingly, the overflow amount of the upstream end of the liquid inlet channel can be increased, the downstream overflow amount of the liquid inlet channel cannot be obviously larger than the upstream overflow amount, and further the water outlet uniformity of a liquid outlet is favorably improved.

Further preferably, the height of the water retaining rib is increased one by one along the water flow direction of the liquid inlet channel. Therefore, the water retaining rib can effectively resist the impact of water flow for many times, and is favorable for improving the water outlet uniformity of the liquid outlet.

Further preferably, the distance between the water retaining ribs is gradually reduced along the water flow direction of the liquid inlet channel. Therefore, the overflow quantity at the downstream of the liquid inlet channel can be further reduced, correspondingly, the overflow quantity at the upstream of the liquid inlet channel can be increased, so that the downstream overflow quantity of the liquid inlet channel can not be obviously larger than the upstream overflow quantity, and the uniformity of water outlet of the liquid outlet can be improved.

Further preferably, the water retaining ribs are located at the middle downstream position of the liquid inlet channel. Therefore, after the water is retained by the water retaining ribs, the downstream overflow amount in the liquid inlet channel is reduced, and the upstream overflow amount of the liquid inlet channel is increased, so that the downstream overflow amount of the liquid inlet channel is not obviously greater than the upstream overflow amount, and the water outlet uniformity of the liquid outlet is improved.

The liquid distributor is usually configured in a long strip shape, preferably, the shell and the cover plate are both in a long strip shape, the liquid inlet channel is arranged on the shell and is arranged along the length direction of the shell

Preferably, the shell is a lower shell, the cover plate is an upper cover plate assembled on the lower shell, and the liquid inlet and the liquid outlet are both arranged on the lower shell. Therefore, water flows upwards from the bottom of the liquid distributor and flows out from the bottom of the liquid distributor, so that water flow can form circuitous flow in the liquid distribution cavity, the water flow speed is slowed down, and the uniformity of discharged water is improved. Of course, the liquid distributor may also adopt an installation structure that the upper shell is matched with the lower cover plate, and correspondingly, the liquid inlet and the liquid outlet may also be arranged on the lower cover plate.

The inlet can have multiple different mounting means, preferably, the tip of casing under the inlet is located to the inlet to, the feed liquor direction perpendicular to of inlet channel is inside rivers direction. Therefore, after the water flow flowing into the liquid inlet is turned, the impact of the water flow on the rear wall of the downstream end of the liquid inlet channel can be reduced, and the overflow amount of the water flow at the downstream of the liquid inlet channel can be reduced.

In order to avoid the inlet inflow water when through the urgency, a large amount of water overflows from the upstream end of inlet channel, the position that the inside wall of inlet channel corresponds the inlet has the breakwater of upwards extending.

Thus, after the liquid outlets are distributed at intervals along the length direction, the uniformity of the discharged water of the liquid outlets is improved.

In order to avoid the situation that the water flow is small, the water overflowing from the upper partition plate directly flows into the liquid outlet, and the vertical projections of the upper partition plate and the liquid outlet on the horizontal plane have no overlapping part.

In order to further improve the water outlet uniformity of the liquid outlets, the liquid outlets are uniformly distributed along the length direction of the water outlet platform at intervals.

Further preferably, the liquid outlet is provided with a flow guide part at the bottom of the water outlet platform. Through setting up water conservancy diversion portion, can make the water that the liquid outlet flows out along the internal face of water conservancy diversion portion, avoid direct flow down.

In order to further improve the uniformity of water flow, the cover plate is provided with a lower partition plate which extends inwards to the liquid distribution cavity, and the lower partition plate is positioned above the water outlet platform. After setting up down the baffle, lower baffle top has formed the cavity that the water supply flow flowed through, under the great condition of velocity of water flow, the water that spills over from inlet channel can flow into the cavity of baffle top down earlier, and the cavity of supreme baffle below is flowed into in the reverse direction again, flows through the liquid outlet at last, and like this, rivers are after circuitous flow many times, can slow down the velocity of flow of liquid outlet to improve out the water homogeneity.

Further preferably, the vertical projections of the lower partition plate and the liquid outlet on the horizontal plane have an overlapping part. Therefore, water flowing into the cavity above the upper partition plate can be prevented from directly flowing downwards from the liquid outlet.

Further preferably, vertical projections of the lower partition plate and the upper partition plate on a horizontal plane have no overlapping part. Because the liquid distributor is usually small in size, if the lower partition plate extends inwards excessively, the sectional area of the water outlet channel is reduced, the water outlet effect is affected, and even the water outlet is difficult.

In order to facilitate installation and positioning, the bottom of the cover plate is provided with positioning blocks extending outwards, and the positioning blocks are distributed at intervals along the length direction of the cover plate.

Detailed Description

The utility model is described in further detail below with reference to the accompanying examples.

As shown in fig. 1 to 5, the liquid distributor of the present embodiment includes a casing 1 and a cover plate 2, both the casing 1 and the cover plate 2 are in a long shape, wherein the casing 1 is a lower casing, the cover plate 2 is an upper cover plate, both the outer side and the two ends of the casing 1 are provided with mounting posts 19, the corresponding positions of the cover plate 2 are provided with mounting lugs 24, during installation, the cover plate 2 covers the casing 1, and screws penetrate through the mounting lugs 24 and are connected and fixed on the corresponding mounting posts 19, so that the cover plate 2 is detachably assembled on the casing 1. After the installation, the cover plate 2 and the shell 1 enclose a liquid distribution cavity 3 together. In this embodiment, the lower housing of the housing 1 is provided with a liquid inlet 11 and a liquid outlet 12, and the liquid inlet 11 is communicated with the liquid outlet 12 through the liquid distribution cavity 3.

In this embodiment, the outer side of the casing 1 is provided with the liquid inlet channel 13, the liquid inlet channel 13 is arranged along the length direction of the casing 1, the liquid inlet channel 13 is a component of the liquid distribution chamber 3, and the liquid inlet 11 is directly communicated with the liquid inlet channel 13. The liquid inlet 11 of this embodiment has 1 and is arranged at the end of the housing 1, and the liquid inlet 11 is communicated with the upstream end of the liquid inlet channel 13, and the liquid inlet direction is perpendicular to the water flow direction inside the liquid inlet channel 13. The inner side wall 131 at the upstream end of the liquid inlet channel 13 is provided with the water baffle 16 extending upwards, and after the water baffle 16 is arranged, the phenomenon that the upstream end of the liquid inlet channel 13 overflows with a large amount of water due to the fact that water rushes out of the upstream end of the liquid inlet channel 13 when the water in the liquid inlet 11 flows through the inlet channel suddenly can be avoided.

As shown in FIG. 6, the inner wall surface of the liquid inlet channel 13 is designed to have an uneven rough structure, and in this embodiment, the surface roughness Ra is not less than 1.6 μm. Like this, the water that inlet 11 flowed in flows the in-process along inlet channel 13 downstream, and the coarse structure of inlet channel 13 inner wall can play the effect that blocks rivers, and then avoids the phenomenon that the overwhelming majority of follow inlet channel 13 downstream end of water in the inlet channel 13 spills over for inlet channel 13's upstream end also can have water to spill over, does benefit to and improves the water homogeneity. Experiments prove that different roughnesses have different blocking effects on water flow, and the larger the roughness is, the better the blocking effect is.

Besides adopting a coarse structure to block water flow, a water retaining piece structure can also be adopted. The direction of the water flow in the inlet channel 13 is shown by the arrow a in fig. 3, and a water blocking member is installed inside the inlet channel 13, and the water blocking member is used for blocking the liquid flowing in from the inlet 11 from directly rushing to the rear wall 132 at the downstream end of the inlet channel 13. The water blocking piece of this embodiment adopts the water blocking muscle 14 of arranging along the rivers direction interval of inlet channel 13, and water blocking muscle 14 is located inlet channel 13's well low reaches, and the water blocking muscle 14 highly increases one by one along inlet channel 13's rivers direction to, the interval of water blocking muscle 14 diminishes gradually along inlet channel 13's rivers direction.

The structure of the water retaining rib 14 is arranged in the liquid inlet channel 13, and in the process that water flow entering the liquid inlet channel 13 from the liquid inlet 11 flows from upstream to downstream, the water flow firstly touches the water retaining rib 14 near the midstream of the liquid inlet channel 13, so that the water flow is prevented from directly rushing to the rear wall 132 of the downstream end of the liquid inlet channel 13, and the water flow continuously flows downstream after crossing the water retaining rib 14 at the position because the height of the water retaining rib is lowest; then, the water flow touches the next water blocking rib 14, namely the middle water blocking rib 14 shown in the figure, because the height of the water blocking rib 14 is higher than that of the previous water blocking rib 14, the water blocking rib 14 further blocks the water flow at the position so as to block the water flow from rushing to the rear wall 132 at the downstream end of the liquid inlet channel 13; when the water flow passes through the middle water blocking rib 14 and then continues to flow downstream, the water flow finally touches the water blocking rib 14 close to the downstream end, the height of the water blocking rib 14 is higher than that of the middle water blocking rib 14, the water flow is further blocked, and the water flow is prevented from rapidly rushing to the rear wall 132 of the downstream end of the liquid inlet channel 13.

The water blocking piece is not limited to the water blocking rib 14, and only needs to have a water flow starting blocking effect, for example, the water blocking piece can adopt a water blocking strip which is spirally arranged, and can also adopt a water blocking strip which is continuously arranged along the water flow direction and is bent back and forth.

Referring to fig. 3 and 7, the top of the inner sidewall 131 of the liquid inlet channel 13 extends to the direction away from the liquid inlet channel 13 to form an upper partition 15, and the upper partition 15 is strip-shaped. The upper partition 15 is provided with a boss 17 extending in a direction away from the liquid inlet channel 13 at a position corresponding to the downstream end of the liquid inlet channel 13, and the boss 17 is provided with a water leakage hole 171. The lower part of the inner side wall 131 of the liquid inlet channel 13 extends to the direction far away from the liquid inlet channel 13 to form a water outlet platform 18, the water outlet platform 18 is in a strip shape, and the water outlet platform is positioned below the upper partition 15 and the boss 17 and is parallel to the upper partition 15 and the boss 17. The liquid outlet 12 is disposed on the water outlet platform 17, and a flow guiding portion 121 is formed at the bottom of the water outlet platform 18 of the liquid outlet 12, as shown in fig. 2. In addition, the liquid outlets 12 are distributed at intervals along the length direction of the water platform 18, and in order to improve the uniformity of the discharged water, in this embodiment, the liquid outlets 12 are distributed at intervals along the length direction of the water platform 18. As shown in fig. 7, the vertical projections of the upper partition 15 and the liquid outlet 12 on the horizontal plane have no overlapping portion, that is, the liquid outlet 12 is located obliquely below the upper partition 15, so that it can be seen that the liquid inlet channel 13 and the liquid outlet 12 are respectively located at two sides of the upper partition 15.

As shown in fig. 5 and 7, the cover plate 2 has a lower partition 21 extending inward into the liquid distribution chamber 3, and the lower partition 21 is located above the water outlet platform 18 and parallel to the water outlet platform 18. The vertical projection of the lower partition plate 21 and the liquid outlet 12 on the horizontal plane has an overlapping part, and in this embodiment, the orthographic projection surface of the lower partition plate 21 on the water outlet platform 18 completely covers the liquid outlet 12. And, the vertical projection of the lower partition 21 and the upper partition 15 on the horizontal plane has no overlapping portion, so that a water flow passage is formed between the lower partition 21 and the inner side wall 131 of the liquid inlet passage 13.

As can be seen from the water flow direction shown by the arrow in fig. 7, after the water flowing into the liquid inlet channel 13 from the liquid inlet 11 overflows from the upper partition 15 inside the liquid inlet channel 13, at this time, the water pressure is relatively large, the water overflowing from the upper partition 15 does not directly flow into the lower liquid distribution cavity 32 below the upper partition 15, but first flows into the upper liquid distribution cavity 31, the water entering the upper liquid distribution cavity 31 flows onto the cover plate inner side wall 26, returns back to the lower partition 21, then flows into the lower liquid distribution cavity 32 after flowing through the lower partition 21, and finally flows out from the liquid outlet 12. Therefore, the water overflowing from the liquid inlet channel 13 flows through collision and multiple roundabouts, the pressure of the water is released, the water outlet speed of the liquid outlet 12 can be slowed down, the overflow amount of the downstream end of the liquid inlet channel 13 is avoided, and the phenomenon that the water overflows at the upstream end of the liquid inlet channel 13 is avoided, so that the water outlet uniformity of the liquid outlet 12 is relatively improved, the overflow amount of the downstream end of the liquid inlet channel 13 is slightly larger than that of the upstream end, and the water outlet requirement of the liquid distributor is met.

As shown in fig. 2, 4, 5 and 7, the bottom of the cover plate 2 of the present embodiment has positioning blocks 22 extending outward, the positioning blocks 22 are distributed at intervals along the length direction of the cover plate 2, and the positioning blocks 22 correspond to the liquid outlets 12 one by one. As shown in fig. 5, the bottom of the cover plate 2 has a support block 23 extending inward, and after the cover plate 2 is mounted on the housing 1, the support block 23 is supported on the water outlet platform 18 of the housing 1 to prevent loosening.

As shown in fig. 8 and 9, the heat dissipation structure of the condenser of the present embodiment includes a condenser 4 and a liquid distributor installed on the condenser. Condenser 4 is including transverse arrangement's last liquid collecting tube 41, lower liquid collecting tube 42 with locate on the liquid collecting tube and between the liquid collecting tube down and interval arrangement's flat pipe 43, install fin 44 between the adjacent flat pipe 43, it communicates each other with lower liquid collecting tube 42 through flat pipe 43 to go up liquid collecting tube 41, the first end of lower liquid collecting tube 42 is the refrigerant entry end, the second end of lower liquid collecting tube 42 is the refrigerant exit end, the refrigerant temperature that the refrigerant entry end flowed in is higher, behind the flat pipe 43 of refrigerant flow, the refrigerant temperature that the refrigerant exit end flowed out is lower relatively. The specific structure and operation principle of the condenser 4 are the same as those of the existing condenser, and will not be described herein.

Referring to fig. 1, the cover plate 2 of the liquid distributor has an arc-shaped mounting plate 25, the arc-shaped mounting plate 25 is fitted with the upper liquid collecting pipe 41 of the condenser 4, and the arc-shaped mounting plate 25 is provided with a threading hole 251. During installation, the arc-shaped mounting plate 25 is attached to the upper header 41 and is tied to the upper header 41 by a thread. The condenser 4 is obliquely arranged relative to the vertical plane, the positioning block 22 of the liquid distributor is obliquely inserted into the gap between the adjacent flat tubes 43, and the liquid outlet 12 of the liquid distributor is obliquely positioned below the positioning block 22 and corresponds to the gap between the adjacent flat tubes 43, that is, the liquid outlet 12 corresponds to the heat dissipation fins 44. The positioning block 22 has a positioning function for the liquid distributor on one hand, and also has a wind shielding function on the other hand, so that the influence of the air flow blowing to the condenser 4 on the water outlet of the liquid outlet 12 to the heat dissipation effect of the condenser can be avoided.

After the liquid distributor is installed, the downstream end of the liquid inlet channel 13 of the liquid distributor corresponds to the first end of the upper liquid collecting pipe 41, the upstream end of the liquid inlet channel 13 corresponds to the second end of the upper liquid collecting pipe 41, and the first end of the upper liquid collecting pipe 41 and the first end of the lower liquid collecting pipe 42 are located on the same side. It can be known through the liquid distributor structure of above-mentioned this embodiment that the water yield of the liquid outlet 13 of the corresponding region of downstream end with inlet channel 13 is relatively great, and the water yield of the liquid outlet 12 of the corresponding region of upstream end with inlet channel 13 is relatively less, therefore, after the refrigerant entry end with inlet channel 13 of liquid distributor and condenser 4 is located the unilateral, can carry out more effective heat dissipation to the refrigerant entry end of condenser 4 to promote the radiating effect of whole condenser.

During operation, water in the liquid distributor flows out of each liquid outlet 12, then just flows into the corresponding heat dissipation fins 44 of the condenser 4, and flows downwards along the surfaces of the heat dissipation fins 44, so that the heat dissipation fins 44 are cooled, and the heat dissipation effect of the condenser is improved.
