Description

Condenser

Technical Field

The present invention relates to a condenser, and more particularly, to a condenser including a flow tube.

Background

Generally, in the immersion cooling system or the trickle cooling system, the dielectric fluid submerged or dripped to the heat source flows to be condensed into a liquid state in the monolithic condenser provided in the rack after being evaporated into a gaseous state. And the gaseous dielectric fluid will flow in the round tubes of the condenser and condense into a liquid.

However, since the round tubes are arranged in the condenser in parallel with each other, it is difficult to arrange the round tubes in a dense manner without interfering with each other, which limits the number of round tubes that can be arranged in the condenser. This reduces the amount of dielectric fluid flowing in the condenser, which in turn reduces the efficiency of the condenser in cooling the dielectric fluid.

Disclosure of Invention

The present invention is directed to providing a condenser to more efficiently cool a working fluid in a flow tube.

The condenser disclosed in one embodiment of the present invention includes two cases, a first exhaust pipe and a second exhaust pipe. The two boxes respectively comprise a mounting surface. Each mounting surface comprises an air outlet side and an air inlet side which are opposite to each other. The first drain pipe comprises a plurality of first drain pipes. The second drain tube includes a plurality of second flow tubes. The first flow tube and the second flow tube are flat. The two opposite ends of each first flow tube are respectively penetrated through the two mounting surfaces of the two boxes and are respectively communicated with the two boxes. The two opposite ends of each second flow tube are respectively communicated with the two mounting surfaces of the two boxes and are respectively communicated with the two boxes. A first heat dissipation gap is formed between every two adjacent first flow tubes. A second heat dissipation gap is formed between every two adjacent second flow pipes. The first heat dissipation gap is communicated with at least one of the second heat dissipation gaps. The first drainage pipe is closer to two air inlet sides of two mounting surfaces of the two boxes than the second drainage pipe.

Another embodiment of the present invention discloses a condenser comprising two tanks and a plurality of flat flow tubes. Each flow tube contains a plurality of flow channels. In each flow tube, the flow channels are not communicated with each other, and the two opposite sides of each flow channel are respectively communicated with the two box bodies.

According to the condenser disclosed in the above embodiments, since the first flow tube and the second flow tube are flat, the first flow tube and the second flow tube can be arranged in a denser manner. Therefore, the heat exchange area between the working fluid in the first flow tube and the second flow tube and the heat dissipation airflow can be increased, and the heat dissipation airflow can effectively cool the working fluid in the first flow tube and the second flow tube.

In addition, the first drainage pipe is closer to two air inlet sides of two mounting surfaces of the two boxes than the second drainage pipe, so that the pipe diameters of the first flow pipe and the second flow pipe can be reduced, and the structural strength of the first flow pipe and the second flow pipe is further improved. Alternatively, because the flow tubes include flow passages that do not communicate with each other, more solid portions of the flow tubes can be retained to increase the structural strength of the flow tubes.

The first tanks 110 of the condensers 100 communicate with each other through the first connection pipe 200. The second tanks 120 of the condensers 100 are communicated with each other through the second connection pipe 300. The inflow pipe 400 is connected to one of the first connection pipes 200 and is used for the inflow of the gaseous working fluid. The outflow pipe 500 is connected to one of the second connection pipes 300 and is used for flowing out the liquid working fluid.

In other embodiments, the heat dissipation assembly may not include the first connection pipe 200 and the second connection pipe 300, in such embodiments, the first tanks of the condensers may not be communicated with each other, the second tanks of the condensers may not be communicated with each other, and the condensers may include an outflow pipe and an inflow pipe respectively.

Since these condensers 100 are similar in structure, only the structure of a single condenser 100 will be described in detail below. Please refer to fig. 3 to 5. Fig. 4 is a plan view of a radiator fin of a condenser of the radiator assembly of fig. 1. Fig. 5 is a partially enlarged view of a cross-sectional view of the condenser of the heat dissipation assembly of fig. 1. The first casing 110 includes a first mounting surface 1100 and a first through-slot 1101. The two first cover plates 115 are respectively fixed to opposite sides of the first case 110 to shield the first through-groove 1101, thereby preventing the working fluid from leaking out of the first through-groove 1101. The first mounting surface 1100 faces away from the first through-slot 1101 and includes a first air outlet side 1103, a first air inlet side 1104 and a plurality of first mounting holes 1105. The first outlet side 1103 and the first inlet side 1104 are opposite to each other. The first mounting hole 1105 communicates with the first through groove 1101. The second housing 120 includes a second mounting surface 1200 and a second through slot 1201. The two second cover plates 125 are respectively fixed to two opposite sides of the second casing 120 to shield the second through-groove 1201, thereby preventing the working fluid from leaking out of the second through-groove 1201. The second mounting surface 1200 is opposite to the second through groove 1201 and includes a second air outlet side 1203, a second air inlet side 1204 and a plurality of second mounting holes 1205. The second air outlet side 1203 and the second air inlet side 1204 face each other. The second mounting hole 1205 is communicated with the second through groove 1201. Further, the first mounting surface 1100 and the second mounting surface 1200 face each other.

The first exhaust pipe 130 includes a plurality of first flow pipes 1300. The second drain pipe 135 includes a plurality of second flow pipes 1350. In the present embodiment, the first and second flowtubes 1300, 1350 are flat tubes, for example. In this embodiment, the first flowtubes 1300 each include a single first flow passage 1310, and the second flowtubes 1350 each include a single second flow passage 1360. Opposite ends of each first flow tube 1300 are respectively inserted into a part of the first mounting hole 1105 of the first mounting surface 1100 of the first housing 110 and a part of the second mounting hole 1205 of the second mounting surface 1200 of the second housing 120, so that the first flow channel 1310 is communicated with the first through groove 1101 and the second through groove 1201. Opposite ends of each of the second flow tubes 1350 are respectively inserted into the other part of the first mounting hole 1105 of the first mounting surface 1100 of the first casing 110 and the other part of the second mounting hole 1205 of the second mounting surface 1200 of the second casing 120, so that the second flow passage 1360 communicates with the first through groove 1101 and the second through groove 1201. A first heat dissipation gap 1301 is formed between two adjacent first flow tubes 1300. A second heat dissipation gap 1351 is formed between two adjacent second flow tubes 1350. In the embodiment, the first heat dissipation gaps 1301 are respectively communicated with the second heat dissipation gaps 1351. The first exhaust pipe 130 is closer to the first wind inlet side 1104 of the first mounting surface 1100 and the second wind inlet side 1204 of the second mounting surface 1200 than the second exhaust pipe 135. In addition, as shown in fig. 5, in the present embodiment, the first flowtubes 1300 are arranged in parallel with each other on a first reference plane P1. The second flow tubes 1350 are arranged parallel to each other on a second reference plane P2. The first reference plane P1 is parallel to the second reference plane P2. In the present embodiment, the first flow tube 1300 and the second flow tube 1350 are aligned to enable the heat dissipation airflow F to pass through the first heat dissipation gap 1301 and the second heat dissipation gap 1351 more smoothly. The working fluid is used to flow from the first through-groove 1101 of the first case 110 to the second through-groove 1201 of the second case 120 through the first flow pipe 1300 and the second flow pipe 1350. In addition, as shown in fig. 5, in the embodiment, the maximum width W1 of the first flow pipe 1300 is equal to the maximum width W2 of the second flow pipe 1350, but the invention is not limited thereto. In other embodiments, the maximum width of the first flow tube may be different from the maximum width of the second flow tube.

As shown in fig. 4 and 5, in the present embodiment, the heat sink set 140 includes a plurality of heat sinks 141. The heat dissipation fins 141 are respectively disposed in the first heat dissipation gap 1301 between the first flow tubes 1300 and the second heat dissipation gap 1351 between the second flow tubes 1350. In addition, in the present embodiment, each of the heat dissipation fins 141 includes a plurality of parallel sections 142 and a plurality of curved sections 143. In each of the heat dissipation fins 141, the parallel sections 142 are parallel to each other, and two opposite sides of each of the bent sections 143 are respectively connected to two adjacent parallel sections 142, so that the heat dissipation fins 141 are, for example, wavy.

Referring to fig. 1 and fig. 2 again, in the present embodiment, the fan case 600 includes a first board 610, a plurality of supporting pillars 620, a second board 630 and a plurality of bumps 640. The first plate 610 is disposed in the first opening 180 and includes a plurality of mounting openings 611. These mounting openings 611 communicate with the heat dissipation channel 170. Opposite ends of each supporting pillar 620 are fixed to the first board 610 and the second board 630, respectively. The protrusion 640 protrudes from the second board 630.

The fans 700 are respectively disposed at the mounting openings 611 and are communicated with the heat dissipation channel 170 to guide the heat dissipation airflow F from the heat dissipation channel 170 to the first heat dissipation gap 1301 between the first flow tubes 1300 and the second heat dissipation gap 1351 between the second flow tubes 1350 of the condenser 100. In other embodiments, the first plate of the fan case may also be disposed in the heat dissipation channel and spaced apart from the first opening, so that the fan is located in the heat dissipation channel and spaced apart from the first opening. Since the heat dissipation airflow F flows from the heat dissipation channel 170 to the first heat dissipation gap 1301 between the first flow tubes 1300 and the second heat dissipation gap 1351 between the second flow tubes 1350, a filter assembly may be disposed upstream of the fan 170, so that the heat dissipation airflow F guided by the fan passes through the filter assembly before passing through the heat dissipation channel 170. As a result, the filter assembly prevents dust from accumulating on the fan 700 or the condenser 100, and thus prevents the performance of the fan 700 or the condenser 100 from being degraded by the dust. In other embodiments, the fan may also direct the heat dissipating airflow in a direction opposite to the direction of the heat dissipating airflow F. That is, in other embodiments, the fan can also guide the heat dissipation airflow flowing from the heat dissipation gap between the flow pipes to the heat dissipation channel. Therefore, the heat dissipation airflow guided by the fan can be discharged in a direction away from the electronic device without affecting the maintenance of the electronic device by a maintenance worker.

In the present embodiment, the wind shielding plate 800 is sandwiched between the bump 640 and the second box 120 and located in the second opening 190. Accordingly, the louver 800 prevents the heat exchange efficiency between the working fluid and the heat dissipation airflow F guided by the fan 700 from being lowered due to the heat dissipation airflow F flowing out of the second opening 190. In other embodiments, the heat dissipation assembly does not need to include the wind shielding plate 800.

Flow tubes according to the present invention are not limited to containing only a single flow channel. Referring to fig. 6, fig. 6 is a partially enlarged view of a cross-sectional view of a heat dissipation assembly according to a second embodiment of the invention. In the present embodiment, each of the first flowtubes 1300a includes a plurality of first flow passages 1310a. The first flow passages 1310a of the respective first flow tubes 1300a do not communicate with each other. Each second flow tube 1350a includes a plurality of second flow passages 1360a. These second flow passages 1360a of the respective second flow tubes 1350a do not communicate with each other.

According to the condenser disclosed in the above embodiments, since the first flow tube and the second flow tube are flat, the first flow tube and the second flow tube can be arranged in a denser manner. Therefore, the heat exchange area between the working fluid in the first flow pipe and the second flow pipe and the heat dissipation airflow can be increased, and the heat dissipation airflow can effectively cool the working fluid in the first flow pipe and the second flow pipe.

In addition, the first drainage pipe is closer to two air inlet sides of two mounting surfaces of the two boxes than the second drainage pipe, so that the pipe diameters of the first flow pipe and the second flow pipe can be reduced, and the structural strength of the first flow pipe and the second flow pipe is further improved. Alternatively, because the flow tubes contain flow passages that do not communicate with each other, more solid portions of the flow tubes can be retained to increase the structural strength of the flow tubes.

In an embodiment of the present invention, the condenser of the present invention can be applied to a server, and the server can be used for Artificial Intelligence (AI) operation and Edge Computing (Edge Computing), and can also be used as a 5G server, a cloud server or a car networking server.

Although the present invention has been described with reference to the foregoing embodiments, it should be understood that various changes, substitutions and alterations can be made herein without departing from the spirit and scope of the invention as defined by the appended claims.
