Example 1
As shown in fig. 1, the heat exchange system provided for this embodiment is suitable for dissipating heat of a data center, and includes a water inlet pipeline 1, a filter 11 and a power pump 12 are disposed on the water inlet pipeline 1, and at least two water inlet pipelines 1 are disposed in parallel at a water inlet of the heat exchange system; the backflushing pipeline 2 is communicated with the two water inlet pipelines 1, the water inlet end of the backflushing pipeline 2 is communicated with the rear end of the power pump 12 on one water inlet pipeline 1, and the water outlet end of the backflushing pipeline 2 is communicated with the front end of the power pump 12 on the other water inlet pipeline 1.
The heat exchange system in the embodiment is used on the subsea data center and used for performing heat dissipation processing on the servers in the subsea data center. As a modified implementation, the heat dissipation can also be performed on a data center arranged at the bottom of a great river. When heat dissipation is carried out, a power pump in the heat exchange system pumps low-temperature seawater into a pipeline in the heat exchange system, and the pipeline through which the seawater flows is arranged in the seabed data center in a deep circulation mode to absorb heat generated by the server and realize cooling treatment of the server.
The heat exchange system in this embodiment has a water inlet and a water outlet, and the heat dissipation pipeline is connected between the water inlet and the water outlet. In order to realize the introduction of the heat exchanger, a water inlet pipeline 1 is installed at the water inlet, the conventional water inlet pipeline 1 is directly contacted with seawater, a power pump 12 is generally arranged on the conventional water inlet pipeline 1, a filter 11 is installed at the water inlet of the water inlet pipeline 1, and the seawater enters the power pump 12 after being filtered, enters a pipeline for radiating the data center, and finally flows out of a water outlet of the heat exchange system.
The power pump 12 is a common water pump structure, and transfers mechanical energy to liquid by the action of the dynamic force of the rotating impeller moving liquid, so that the liquid flows. As a variation, in some embodiments, a common positive displacement pump or the like may also be employed.
In the heat exchange system in this embodiment, when the heat dissipation treatment is normally performed, the backflushing pipeline is closed, and the at least two water inlet pipelines 1 pump low-temperature seawater and the like to the heat exchange system under the action of the power pump 12 and flow out through the water outlet of the heat exchange system to perform circulation flow, so that the heat dissipation of the data center is realized. When the heat exchange system works for a period of time and the filter 11 on the water inlet pipeline 1 needs to be cleaned, the backflushing pipeline is opened, the water inlet pipeline 1 connected with the water outlet end of the backflushing pipeline is closed, at the moment, a part of fluid in the water inlet pipeline 1 which is not closed enters the heat exchange system under the action of the power pump 12, the heat dissipation function is continuously realized, a part of fluid reversely flows into the closed filter 11 in the water inlet pipeline 1 through the backflushing pipeline, the filter 11 is reversely flushed, and therefore impurities or microorganisms attached to the filter 11 are cleaned. When different filters 11 need to be cleaned, the cleaning work of all the filters 11 can be sequentially realized by repeating the operation process.
In order to clearly show the working principle of the heat exchange system of the present invention, only two water inlet pipes 1 are exemplified in the present embodiment, and other numbers of water inlet pipes 1 are also within the scope of the present invention. In order to distinguish the two water inlet pipelines 1 in the following process, suffixes a and b are defined in the embodiment respectively, and the same suffixes are added after the devices arranged on the suffixes. As shown in particular in figure 1.
As shown in fig. 1, two water inlet pipelines 1 are connected in parallel at the water inlet of the heat exchanging system, so that a section of pipeline shared by the two water inlet pipelines is derived at the water inlet in order to facilitate the parallel arrangement of the two water inlet pipelines 1a and 1b, and the pipe diameter of the shared pipeline can be set to be larger, so as to ensure that the incoming water can be guided out in time when the two water inlet pipelines simultaneously enter water.
In addition, as a further limitation, as shown in fig. 1, the backflushing pipe 2 is provided with a first closing valve 21, the first closing valve 21 is a common opening and closing valve, and as a modification, for convenience of control, an electromagnetic opening and closing valve may be used to close the backflushing pipe 2 for normal heat dissipation operation when the heat exchange system does not need to clean the filter 11.
In addition to the above embodiments, as a further limitation, as shown in fig. 1, the backflushing pipe 2 is provided with a first check valve 22, which can prevent the power pump 12 from being damaged due to the backflow problem caused by the excessive water pressure in the pipe at the rear end of the flushed filter 11 due to the serious blockage at the position of the filter 11 during the backflushing.
To further limit the above embodiment, as shown in fig. 1, the water inlet pipeline 1 further includes a second check valve 13 disposed between the water inlet and the power pump 12, which on one hand can prevent the problem of water backflow at the water inlet; on the other hand, the problem of series flow among a plurality of water inlet pipelines 1 which are connected in parallel on the same water inlet can be prevented.
To further limit the above embodiment, as shown in fig. 1, the water inlet circuit 1 further comprises a second shut-off valve 14 disposed between the filter 11 and the power pump 12 for controlling the on/off of the water inlet circuit 1 to facilitate the subsequent back flushing operation.
The heat exchange system in fig. 1 therefore has the following operating steps:
and (3) a conventional heat dissipation mode: the first closing valves 21a and 21b are closed, the water inlet pipelines 1a and 1b are not communicated at this time, the second opening and closing valves 14a and 14b are opened, the power pumps 12a and 12b work, and the seawater flows into the heat exchange system through the power pumps 11a and 11b to perform heat dissipation treatment on the heat exchange system.
As another operation mode, in the case of the heat dissipation requirement of the data center, only one water inlet pipeline 1a or 1b may be controlled to be opened, and the other water inlet pipelines 1 may be closed, so as to control the heat dissipation effect and save energy.
Back-flush filter 11a mode: when the power pump 12b is normally operated, the power pump 12a is closed, the first on-off valve 21b is opened, the second on-off valve 14b is opened, and the second on-off valve 14a is closed, under the pumping action of the power pump 12b, part of seawater passes through the filter 11b and flows into the water inlet through the second one-way valve 13b, and part of seawater enters the filter 11a through the one-way valve 22b, so that the filter 11a is back-flushed.
Back flush filter 11b mode: when the power pump 12a is normally operated, the power pump 12b is closed, the first on-off valve 21a is opened, the second on-off valve 14a is opened, and the second on-off valve 14b is closed, under the pumping action of the power pump 12a, part of seawater passes through the filter 11a, flows into the water inlet through the second one-way valve 13a, and part of seawater enters the filter 11b through the one-way valve 22a, so that the filter 11b is back-flushed.
In the embodiment, two water inlet pipelines 1 are exemplified, and two back flushing pipelines 2 are arranged for realizing back flushing of filters on the two pipelines.
In addition, as a further limitation, a differential pressure detecting device, such as a conventional differential pressure detecting device, is further included, and is disposed at two ends of the power pump 12a or 12b, and is connected in parallel to two ends of the power pump 12. The differential pressure detection device controls the opening and closing of the power pump 12 according to the change of the differential pressure. Specifically, when the amount of microorganisms or impurities attached to the filter 11 is excessive, the water flow passing through the filter 11 is reduced, the differential pressure value before and after the power pump 12 is increased, and the blocking condition of the filter 12 can be judged according to the change condition of the differential pressure value detected by the differential pressure detection device, so that the heat exchange system can control when the backflushing pipeline is opened to flush the filter. As a specific embodiment, when the power pump 12 is set as the heat exchange system in the normal heat dissipation mode, the maximum allowable pressure across the power pump 12 is 10MP, and when the pressure difference detection device detects that the pressure across the power pump 12 is greater than 10MP, the heat exchange system is controlled to enter the flushing mode.
As a modified embodiment, a timer is further included to detect the operating time of the power pump 12. In order to simplify the control of the heat exchange system, a timer is installed thereon, and the timer counts the operation mode of the heat exchange system, for example, when the heat exchange system operates for three hours in the conventional heat dissipation mode, the operation mode for flushing the filter 12 is automatically entered. After fifteen minutes of filter 12 flushing, the backflush circuit is again closed and returned to the normal heat removal mode in the heat exchange system.
On the basis of the above-described embodiment, as a further limitation, at least two filters 11 are arranged in parallel on the water inlet line 1. The arrangement of the filters 11 can accelerate the filtration efficiency of water flow, increase the water flow at the water inlet of the power pump 12, improve the flow of pumping and further improve the heat exchange efficiency of the whole heat exchange system.
In addition to the above-mentioned embodiments, at least two layers of filter elements are arranged in the filter 11 in parallel and at intervals in the fluid flowing direction. When the water flow in the sea bottom or the river bottom is pumped, besides large weeds, stones and the like, various microorganisms and the like exist, the microorganisms in the marine ecosystem are protected, the ecological balance at the position of a data center is not damaged, besides a conventional filter element such as an activated carbon filter element or a large-aperture filter screen is arranged in the filter 11, a precise filter element such as an RO (reverse osmosis) membrane filter element and the like is also arranged, and the microorganisms in the sea bottom are blocked outside the filter to be prevented from entering the heat exchange system.
In addition to the above embodiments, as a further limitation, a sterilizing device is further installed in the filter 11. When the water flow in the sea bottom or the river bottom is pumped, bacteria, viruses and the like exist in the water flow, the bacteria, the viruses and the like can be attached to the filter, the filter element can be corroded after a long time, or the sanitation level of the filter is reduced, the subsequent personnel can not clean the filter conveniently, and therefore the disinfection device is arranged for killing the bacteria or the viruses. The disinfection device is constructed as an ultraviolet disinfection lamp, which has low cost and simple installation.

Wherein the number of heat exchange systems can be designed adaptively according to the heat dissipation requirements of each data pod.
