Detailed description of the invention
Below embodiments of the invention are described in detail, but the multitude of different ways that the present invention can be defined by the claims and cover is implemented.
In figure, the direction of arrow represents the flow direction of fluid.
Please refer to Fig. 2 to 5, according to embodiments of the invention, evaporimeter comprises feed tube 1, upper evaporimeter 2 and lower evaporimeter 3, lower evaporimeter 3 is arranged on the below of evaporimeter 2, upper evaporimeter 2 comprises the first lower collector pipe 4 and the first upper header 5, lower evaporimeter 3 comprises the second lower collector pipe 6 and the second upper header 7, and feed tube 1 is connected to the entrance point of the first lower collector pipe 4, and is communicated to the entrance point of the second lower collector pipe 6 after the first lower collector pipe 4.
During this evaporator operation, after cold-producing medium enters evaporimeter from feed tube 1, the entrance point of the first lower collector pipe 4 can be flowed into from feed tube 1, then enter in the first lower collector pipe 4.Part of refrigerant enters the heat exchanger tube of evaporimeter 2 afterwards, and another part cold-producing medium flows to the entrance point of the second lower collector pipe 6 after the first lower collector pipe 4, then enters into the heat exchanger tube of lower evaporimeter 3.Thus, by arranging upper and lower two evaporimeters, the tube side of heat exchanger tube in each evaporimeter can be shortened, making the hot-air flowing through evaporimeter 2 and lower evaporimeter 3 all can obtain abundant heat exchange, making full use of the heat exchange area of whole evaporimeter.Simultaneously, because cold-producing medium flows in the second lower collector pipe 6 after the first lower collector pipe 4, cold-producing medium all can fully be flowed in the first lower collector pipe 4 and the second lower collector pipe 6, can fully enter in the heat exchanger tube of evaporimeter 2 and lower evaporimeter 3, therefore, it is possible to make the heat exchange efficiency of upper and lower two evaporimeters substantially be consistent, improve the refrigerating efficiency of overall evaporimeter.
Be communicated with by outlet connecting pipe 14 between first upper header 5 and the second upper header 7, then cold-producing medium is exported from evaporimeter by the pipeline of the port of export being positioned at the first upper header 5.Certain first upper header 5 and the second upper header 7 also can export from evaporimeter respectively.
In conjunction with shown in Figure 2, according to the first embodiment of the present invention, be communicated with by inlet connecting branch 8 between first lower collector pipe 4 with the second lower collector pipe 6, the first end of inlet connecting branch 8 is connected to one end away from entrance point of the first lower collector pipe 4, and the second end of inlet connecting branch 8 is connected to the entrance point of the second lower collector pipe 6.First end due to inlet connecting branch 8 is connected to one end away from entrance point of the first lower collector pipe 4, therefore when the entrance point of cold-producing medium through the first lower collector pipe 4 enters into after in the first lower collector pipe 4, first whole first lower collector pipe 4 can be flowed through, part of refrigerant can be entered in the heat exchanger tube of evaporimeter 2 fully, carry out heat exchange fully.Then another part cold-producing medium directly enters in the second lower collector pipe 6 through the first lower collector pipe 4 and inlet connecting branch 8, carries out heat exchange in the heat exchanger tube then entering into lower evaporimeter 3 from the second lower collector pipe 6.
By adopting the mode of the present embodiment, cold-producing medium is just flowed in the second lower collector pipe 6 after the first lower collector pipe 4, cold-producing medium can be made under gravity, can flow into fully in the heat exchanger tube of evaporimeter 2, and be unlikely to not flow through evaporimeter 2 and directly enter in the second lower collector pipe 6, therefore can ensure that evaporimeter 2 and lower evaporimeter 3 can carry out sufficient heat exchange, improve the heat exchange efficiency of whole evaporimeter.
In the present embodiment, inlet connecting branch 8 comprise be connected to the first lower collector pipe 4 linkage section 9, to be connected with linkage section 9 and the bending section 10 extended along the bearing of trend of the first lower collector pipe 4 to the entrance point of the first lower collector pipe 4 and be connected with bending section 10 and extend to the transportation section 11 of the entrance point of the second lower collector pipe 6.Linkage section 9 is arranged on the outlet of the first lower collector pipe 4, for being drawn by the cold-producing medium being positioned at the first lower collector pipe 4.The bearing of trend of bending section 10 is consistent with the bearing of trend of the first lower collector pipe 4, therefore the space taken between evaporimeter 2 and lower evaporimeter 3 is less, more be convenient to the layout of evaporimeter 2 and lower evaporimeter 3, overall evaporation structure can be made compacter, take up room less.
In conjunction with shown in Figure 3, according to a second embodiment of the present invention, be connected with liquid storage pipe 12 between the first lower collector pipe 4 of upper evaporimeter 2 and the second upper header 7 of lower evaporimeter 3, connected as one by liquid storage pipe 12 between upper evaporimeter 2 and lower evaporimeter 3.Be communicated with by being communicated with arm 13 between liquid storage pipe 12 with the first lower collector pipe 4, the outlet of liquid storage pipe 12 is arranged on one end of the entrance point near the second lower collector pipe 6, the outlet of liquid storage pipe 12 and the entrance point of the second lower collector pipe 6 are connected with inlet connecting branch 8, and the other end of liquid storage pipe 12 is closed.
In the present embodiment, it is multiple for being communicated with arm 13, and multiple connection arm 13 is arranged along the length direction interval of liquid storage pipe 12, and reduces gradually from the direction spacing distance of the outlet away from liquid storage pipe 12.
The speed that cold-producing medium due to the exit position place the closer to liquid storage pipe 12 flows to the second lower collector pipe 6 is under gravity faster, therefore, by multiple connection arm 13 along the direction away from liquid storage pipe by dredging solid matter cloth, cold-producing medium directly flow to the second lower collector pipe 6 speed from the first lower collector pipe 4 can be slowed down, when the cold-producing medium that guarantee flows in the second lower collector pipe 6 is enough, the heat exchanger tube making evaporimeter 2 and lower evaporimeter 3 all can fully heat exchange, make full use of the heat exchange area of evaporimeter, improve heat exchange efficiency.
In conjunction with shown in Figure 4, according to the third embodiment of the invention, it is substantially identical with the second embodiment, and difference is, in the present embodiment, being communicated with arm 13 is one, is communicated with arm 13 and is arranged on liquid storage pipe 12 one end away from outlet.This kind of structure can ensure that cold-producing medium can have sufficient flow distance in the first lower collector pipe 4, thus ensures to enter enough cold-producing mediums, the refrigerating efficiency of evaporimeter 2 in raising in upper evaporimeter 2.
In conjunction with shown in Figure 5, according to a further aspect in the invention, provide a kind of rack, comprise server 15, evaporimeter and condenser, this evaporimeter is above-mentioned evaporimeter, and evaporimeter is arranged in the back door of server 15.
These are only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
