[Figure 2] This is a rear perspective view of an ejector cooling device according to one embodiment of the present disclosure. [Figure 3] This figure shows a part of the internal structure of an ejector cooling device according to one embodiment of the present disclosure. [Figure 4] This figure visualizes the internal structure of the opening / closing member of an ejector cooling device according to one embodiment of the present disclosure. [Figure 5] This figure shows the main airflow when the inside of an ejector cooling device according to one embodiment of this disclosure is visualized from the side. [Modes for carrying out the invention]

[0009] The following description relates to an ejector cooling device according to one embodiment of the present disclosure. Common or corresponding elements are denoted by the same or similar reference numerals, and redundant descriptions are omitted or simplified as appropriate. In each figure, the configuration is shown enlarged, reduced, or omitted as appropriate for the sake of explanation. To improve the visibility of the drawings, elements in the figures may be shown with lines other than solid lines (such as dashed lines or dotted lines) as needed.

[0010] Any reference to elements using designations such as “First,” “Second,” etc., as used in this disclosure, does not generally limit the quantity or order of those elements. These designations are used for convenience to distinguish between two or more elements. Therefore, references to the First and Second elements do not imply, for example, that only two elements are adopted, or that the First element must precede the Second element.

[0011] Figure 1 is a front perspective view of an ejector cooling device 1 according to one embodiment of the present disclosure. Figure 2 is a rear perspective view of the ejector cooling device 1. Figure 3 is a diagram visualizing a part of the internal structure of the ejector cooling device 1.

[0012] The ejector cooling unit 1 is connected to, for example, production equipment installed in factories or plants, or a CDU (Coolant Distribution Unit) in a data center. The ejector cooling unit 1 cools the hot water (refrigerant) discharged from the connected equipment, such as production equipment or a CDU, and returns it to the connected equipment. At the connected equipment, the cooled refrigerant is used to cool the equipment, and the high-temperature refrigerant is discharged again. The ejector cooling unit 1 cools the discharged refrigerant and returns it to the connected equipment again. In this way, the cooling cycle is repeated.

[0013] The ejector cooling device 1 comprises a housing 2. The housing 2 is made of metal, for example, in view of heat dissipation. An opening OP is formed on the front surface 2A of the housing 2. That is, the housing 2 has an opening OP.

[0014] The ejector cooling device 1 includes an opening / closing member 3. The opening / closing member 3 is box-shaped and houses a control device 30. The control device 30 is, for example, a PLC (Programmable Logic Controller). The control device 30 controls the operation of the ejector cooling device 1. The "opening / closing member 3" may be replaced with "electrical panel".

[0015] The opening / closing member 3 is attached to the housing 2. Specifically, the opening / closing member 3 is attached to the housing 2 via, for example, a hinge or the like, and covers the opening OP of the front surface 2A of the housing 2 in an openable / closable manner. FIG. 3 is a view showing the internal structure of the ejector cooling device 1 in a visualized manner and showing the state in which the opening / closing member 3 is open. Thus, the opening / closing member 3 is an example of an opening / closing member that covers the opening OP in an openable / closable manner.

[0016] An intake port 4 is provided on the front surface 2A of the housing 2. More specifically, the intake port 4 is provided at the lower part of the front surface of the opening / closing member 3. The intake port 4 is an example of an intake port for sucking air into the housing 2. An exhaust port 6 is provided on the rear surface 2C of the housing 2. Although it will be described in detail later, the air sucked in through the intake port 4 flows inside the opening / closing member 3, further flows inside the housing 2, and is discharged to the outside through the exhaust port 6 provided on the rear surface 2C of the housing 2. Thereby, the ejector cooling device 1 is cooled. By forming the exhaust port 6 larger than the intake port 4, the pressure loss of the air flowing from the intake port 4 to the exhaust port 6 can be reduced.

[0017] Inside the housing 2, a circulation path for circulating the refrigerant is installed. The circulation path of the refrigerant includes a steam generator, an ejector, a condenser, a pump, an evaporator, an auxiliary cooler, and the like. In the present embodiment, for the sake of convenience, some of the components constituting the circulation path are illustrated, and the illustration of the remaining components constituting the circulation path is omitted. Specifically, the steam generator, the ejector, the condenser, and the pump are illustrated and are respectively denoted by reference numerals 11, 12, 13, and 14.

[0018] In the circulation path, the steam generator 11 performs heat exchange to heat the refrigerant flowing in from the pump 14 with the warm water supplied from the outside (for example, CDU). The steam generator 11 supplies the refrigerant evaporated by the heat exchange as a driving flow to the ejector 12.

[0019] In the ejector 12, the refrigerant supplied from the steam generator 11 flows in as a driving flow, and the refrigerant evaporated by the evaporator is sucked in as a suction flow. The ejector 12 discharges the refrigerant obtained by mixing the driving flow and the suction flow to the condenser 13.

[0020] The refrigerant discharged from the ejector 12 flows into the condenser 13. The condenser 13 performs heat exchange with the heat radiation water supplied from the outside and condenses the refrigerant. The heat radiation water is, for example, heated by heat exchange with the refrigerant in the condenser 13 and then sent to an external cooling device (such as a cooling tower). The heat radiation water is cooled by the cooling device and then sent back to the condenser 13 to condense the refrigerant.

[0021] The refrigerant condensed by the condenser 13 is sucked by the pump 14 and sent to the steam generator 11. In this way, the refrigerant circulates in the circulation path.

[0022] In the ejector cooling device 1, due to the influence of the temperature inside the housing 2, for example, there is a concern that the temperature of the refrigerant may fluctuate inappropriately and the refrigerant cannot be circulated properly in the circulation path. Therefore, in the present embodiment, the ejector cooling device 1 is configured to be able to appropriately cool the inside of the housing 2.

[0023] As a more specific example, among the members constituting the circulation path, there are members to be cooled and members that are not actively desired to be cooled.

[0024] For example, the pump 14 generates heat during operation. If the pump 14 overheats, for example, burnout of the motor, deterioration of internal parts such as the impeller, seizure, and reduction of the liquid delivery capacity may occur. Therefore, the pump 14 is one of the members to be cooled.

[0025] For example, the steam generator 11 generates high-temperature and high-pressure refrigerant vapor and supplies it as a driving flow to the ejector 12. If the steam generator 11 is cooled, it becomes difficult to generate high-temperature and high-pressure refrigerant vapor, and there is a possibility that a sufficient driving flow cannot be supplied to the ejector 12. Therefore, the steam generator 11 is one of the members that are not actively desired to be cooled. Also, if the ejector 12 is cooled, the temperature of the driving flow may decrease and the discharge performance of the refrigerant by the ejector 12 may decrease. The ejector 12 is also one of the members that are not actively desired to be cooled.

[0026] Thus, inside the housing 2, there is a mixture of components that need to be cooled and components that do not need to be actively cooled. Therefore, the ejector cooling device 1 according to this embodiment is configured such that the air flowing inside the housing 2 does not easily come into contact with components that do not need to be actively cooled, by appropriately setting the position of the exhaust port 6 (more specifically, the airflow from the intake port 4 to the exhaust port 6).

[0027] Specifically, the ejector cooling device 1 comprises a housing 2 that houses a first component and a second component to which a refrigerant at a higher temperature than the first component is supplied, and an exhaust port 6 provided in the housing 2 for discharging air from inside the housing 2. The second component is held inside the housing 2 at a position higher than the height of the exhaust port 6.

[0028] The first component is, for example, a component that generates heat during operation, and is held inside the housing 2 at a position lower than the height of the exhaust port 6.

[0029] The first and second members constitute, for example, a refrigerant circulation path.

[0030] As an example, the first component is a pump 14 that circulates the refrigerant in the circulation path.

[0031] As an example, the second component is a steam generator 11 that generates high-temperature, high-pressure refrigerant vapor and supplies it to the ejector 12 as a driving flow. The ejector 12 is also an example of a second component.

[0032] In this embodiment, by holding the second member at a position higher than the height of the exhaust port 6 within the housing 2, the air flowing inside the housing 2 is less likely to directly hit the second member, which is not to be actively cooled. This reduces the likelihood of heat exchange due to air cooling occurring in the second member (e.g., the steam generator 11), and stabilizes the drive flow supplied from the steam generator 11 to the ejector 12, for example. In this way, the ejector cooling device 1 is configured in this embodiment to appropriately cool the inside of the housing 2.

[0033] Furthermore, the ejector cooling device 1 includes, for example, an air intake 4 for drawing air into the housing 2. The ejector cooling device 1 includes fans (e.g., 42a, 42b, 42c) installed in the air passage between the air intake 4 and the exhaust port 6 to create an airflow from the air intake 4 to the exhaust port 6. The fans are an example of blowers. The fans may be replaced with other forms of devices having a blowing function.

[0034] The intake port 4 is, for example, located at a lower position than the exhaust port 6.

[0035] The fan 42a is installed, for example, adjacent to the pump 14 (an example of the first component).

[0036] The fans (for example, 42a, 42b, 42c) are held inside the enclosure 2 at a position lower than the height of the exhaust port 6.

[0037] Since the second component (for example, the steam generator 11) is held within the housing 2 at a position higher than the height of the exhaust port 6, the air flowing from the intake port 4 to the exhaust port 6 is less likely to directly hit the second component. By positioning the intake port 4 at a lower height than the exhaust port 6, the air flowing from the intake port 4 to the exhaust port 6 is even less likely to hit the second component.

[0038] By installing a fan in the air passage between the intake port 4 and the exhaust port 6, the air flowing from the intake port 4 to the exhaust port 6 is more likely to hit components located in the air passage. As a result, the ejector cooling device 1 is cooled efficiently. For example, the fan 42a is installed adjacent to a component that generates heat when the pump 14 is in operation (an example of the first component). This allows for efficient cooling of the heat-generating component such as the pump 14.

[0039] Conventional ejector cooling systems had air intakes located on the sides of the enclosure. Depending on the installation location of the ejector unit, other equipment, devices, or walls within the installation room may be located close to the sides of the enclosure. In some cases, the sides of the enclosure may be completely covered by other equipment, devices, or walls, nearly blocking the air intakes. In these cases, it was difficult to draw in outside air into the enclosure, making it difficult to properly cool the inside of the enclosure.

[0040] Therefore, in this embodiment, the air intake port 4 is installed in a position that makes it easy to draw in air.

[0041] Specifically, the ejector cooling device 1 comprises a housing 2, an operation panel 5 (an example of an operating member) provided on the first outer surface of the housing 2 (for example, the front surface 2A), and an air intake port 4 for drawing air into the housing 2. The air intake port 4 is provided on the first outer surface of the housing 2 (for example, the front surface 2A).

[0042] The control panel 5 is, for example, a POD (Programmable Operation Display) connected to the control device 30, which is a PLC. The operator uses the control panel 5 to monitor and operate the ejector cooling device 1. In order to secure space for the operator to operate the control panel 5, the ejector cooling device 1 is installed in a layout in which other equipment, devices, walls, etc. are not located close to the first outer surface (for example, the front 2A) of the housing 2. Other equipment, devices, walls, etc. are not located close to the air intake 4 provided on the front 2A of the housing 2. Therefore, the ejector cooling device 1 can easily take in air into the housing 2 through the air intake 4, and the inside of the housing 2 can be properly cooled. In addition, even if other equipment, devices, walls of the installation room, etc. are located close to the side 2B of the housing 2, sufficient air can be taken in into the housing 2 through the air intake 4, and the inside of the housing 2 can be properly cooled.

[0043] The ejector cooling device 1 is equipped with an exhaust port 6 for discharging air from inside the housing 2. The exhaust port 6 is provided on a second outer surface of the housing 2, which is different from the first outer surface of the housing 2 (for example, the front surface 2A).

[0044] The second outer surface is, for example, the outer surface opposite the first outer surface. As an example, the second outer surface is the back surface 2C of the housing 2.

[0045] The intake port 4 is located at a lower position than the exhaust port 6.

[0046] The ejector cooling device 1 is installed in the air passage between the intake port 4 and the exhaust port 6 and includes a fan (42a, or 42b and 42c) that generates an airflow from the intake port 4 to the exhaust port 6.

[0047] The ejector cooling device 1 includes a first component (e.g., a pump 14) that generates heat when in operation. For example, a fan 42a is installed adjacent to a component (an example of a first component) that generates heat when in operation, such as the pump 14.

[0048] By providing the exhaust port 6 on a second outer surface of the housing 2, which is different from the first outer surface (the surface on which the intake port 4 is provided), air drawn in from the first outer surface can easily flow through the housing 2 and escape to the second outer surface. In other words, air drawn in from the intake port 4 can easily escape through the exhaust port 6 without remaining inside the housing 2. This allows fresh air to easily pass through the housing 2, and the inside of the housing 2 can be cooled more effectively.

[0049] Furthermore, by providing the exhaust port 6 on the second outer surface (e.g., the rear surface 2C) opposite the first outer surface (e.g., the front surface 2A) of the housing 2, air drawn in from the front can more easily flow through the housing 2 to the rear. Air drawn in from the intake port 4 can easily escape through the exhaust port 6 without remaining inside the housing 2. This allows fresh air to pass through the housing 2 more easily, and the inside of the housing 2 can be cooled more effectively.

[0050] By positioning the intake port 4 at a lower height than the exhaust port 6, air drawn in through the intake port 4 and heated through heat exchange with components inside the housing 2 is more easily discharged through the exhaust port 6. By installing a fan in the air passage between the intake port 4 and the exhaust port 6, the air heated through heat exchange is even more easily discharged through the exhaust port 6. For example, by installing a fan 42a adjacent to a component that generates heat when operating, such as the pump 14 (an example of a first component), the heat-generating component such as the pump 14 can be efficiently cooled.

[0051] The ejector cooling device 1 comprises a housing 2 having an opening OP, an opening / closing member 3 (for example, an electrical panel) that covers the opening OP in an openable / closable manner, and an air intake port 4 for drawing air into the housing 2. The air intake port 4 is provided on the opening / closing member 3.

[0052] An operator can, for example, open the opening / closing member 3 and access the inside of the housing 2. Once inside the housing 2, the operator can, for example, replace or repair components inside the housing 2 as needed. In order to secure space for opening the opening / closing member 3, the ejector cooling device 1 is installed in a layout in which other equipment, devices, or walls are not located near the opening / closing member 3. Other equipment, devices, or walls are not located close to the air intake port 4 provided on the opening / closing member 3. Therefore, the ejector cooling device 1 can easily take in air into the housing 2 through the air intake port 4, enabling proper cooling of the inside of the housing 2. In addition, even if other equipment, devices, or walls in the installation room are located close to the side 2B of the housing 2, sufficient air can still be taken in into the housing 2 through the air intake port 4, enabling proper cooling of the inside of the housing 2.

[0053] In this embodiment, the air intake port 4 is positioned in a location that facilitates air intake, even from this perspective.

[0054] From another perspective, the configuration allows access to the inside of the housing 2 by opening the opening / closing member 3, which enables, for example, an operator to replace or repair components inside the housing 2 as needed. In this embodiment, for example, the pump 14, which has a relatively short service life among the components inside the housing 2, is installed near the back of the opening / closing member 3 (in other words, in an easily accessible location). Therefore, the operator can easily replace or repair the pump 14 by opening the opening / closing member 3. Thus, according to this embodiment, the maintainability of the ejector cooling device 1 is improved.

[0055] The opening / closing member 3 is formed, for example, in a box shape and houses the control device 30. As a more specific example, the opening / closing member 3 is configured as an electrical panel.

[0056] The air intake port 4 is provided, for example, at the bottom of the opening / closing member 3. First vents (for example, vents 43b and 43c of fans 42b and 42c) are provided at the top of the opening / closing member 3 to discharge the air that has been drawn into the housing 2 (more specifically, into the opening / closing member 3 which is part of the housing 2) through the air intake port 4.

[0057] For example, a duct 41 connecting the air intake 4 and the vents 43b and 43c (an example of the first vent) is provided inside the opening / closing member 3.

[0058] For example, a first blower (e.g., fans 42b, 42c) is provided to send air drawn into the opening / closing member 3 via the intake port 4 into the housing 2 via the first vents (e.g., vents 43b, 43c of fans 42b, 42c).

[0059] The ejector cooling device 1 includes, for example, a second vent (e.g., a vent 43a of a fan 42a) provided on the opening / closing member 3 and discharging air drawn into the opening / closing member 3 via the intake port 4, a second blower (e.g., a fan 42a) that sends air drawn into the opening / closing member 3 via the intake port 4 into the housing 2 via the second vent, and a first component (e.g., a pump 14) held inside the housing 2 and generating heat when driven. In this case, the first component and the second blower are installed in a position adjacent to the first component when the opening / closing member 3 is closed.

[0060] Air drawn in through the air intake 4 located at the bottom of the opening / closing member 3 passes through the inside of the opening / closing member 3 and is discharged into the housing 2 through the vents 43b and 43c located at the top of the opening / closing member 3. The control device 30, which is equipped with many electronic components that generate heat during operation, is cooled by heat exchange with the air passing through the inside of the opening / closing member 3.

[0061] As a more specific example, in this embodiment, a duct 41 is provided inside the opening / closing member 3. By providing the duct 41, air drawn in from the intake port 4 passes through the opening / closing member 3 and is sent into the housing 2 more efficiently. In this case, the control device 30 inside the opening / closing member 3 is cooled by the air flowing through the duct 41 (due to the influence of the wind generated inside the duct 41). By placing heat-generating components of the control device 30 inside the duct 41, the control device 30 can be cooled even more efficiently.

[0062] By installing the first component (e.g., pump 14) and the second blower (e.g., fan 42a) adjacent to each other when the opening / closing member 3 is closed (in other words, when the ejector cooling device 1 can be operated), the air drawn in from the intake port 4 is more easily directed directly onto the pump 14 by the fan 42a. As a result, the pump 14 can be cooled efficiently.

[0063] The airflow cooling the ejector cooling device 1 will be explained primarily using Figures 3 to 5. As mentioned above, Figure 3 is a diagram visualizing a part of the internal structure of the ejector cooling device 1. Figure 4 is a diagram visualizing the internal structure of the opening / closing member 3. Figure 5 is a diagram showing the main airflows AF1 and AF2 when the inside of the ejector cooling device 1 is visualized from the side.

[0064] As shown in Figure 5, air is drawn into the ejector cooling device 1 from the intake port 4. The drawn-in air mainly flows in the direction of the arrows labeled AF1 and AF2. More specifically, air also flows in directions other than those indicated by arrows AF1 and AF2. For convenience, only the main airflow is described here, and the airflow other than that indicated by arrows AF1 and AF2 is omitted.

[0065] One end of the duct 41 is connected to the air intake 4. The duct 41 branches into three duct sections 41a, 41b, and 41c. Fans 42a, 42b, and 42c are installed at the base ends of the branched duct sections 41a, 41b, and 41c, respectively.

[0066] As shown by arrow AF2 in Figure 5, a portion of the air drawn in from the intake port 4 flows through the duct section 41a (see arrow Aa in Figure 4) and is sent into the housing 2 via the vent port 43a by the fan 42a. Since the fan 42a is positioned adjacent to the pump 14, the air sent into the housing 2 via the vent port 43a directly hits the pump 14, efficiently cooling it. The air whose temperature has risen due to heat exchange with the pump 14 flows through the housing 2 and is discharged to the outside via the exhaust port 6, as shown by arrow AF2.

[0067] Furthermore, as a result of the configuration in which the pump 14 and fan 42a are located adjacent to each other when the opening / closing member 3 is closed, the pump 14 is located close to the back of the opening / closing member 3. Because the pump 14 is located near the back of the opening / closing member 3 (in other words, at the front of the housing 2), the operator can easily access the pump 14. For example, the operator can easily replace or repair the pump 14 by opening the opening / closing member 3. In this way, the maintainability of the ejector cooling device 1 is improved.

[0068] A portion of the air drawn in from the intake port 4 flows through the duct sections 41b and 41c (see arrows Ab and Ac in Figure 4) and is then sent into the housing 2 via the vents 43b and 43c by fans 42b and 42c, as shown by arrow AF1 in Figure 5. The operation panel 5 is installed directly above the opening / closing member 3. Therefore, the air sent into the housing 2 by fans 42b and 42c easily hits the operation panel 5. The operation panel 5 generates heat when in operation. For example, a portion of the air sent into the housing 2 hits the operation panel 5, cooling the heated operation panel 5. The air sent into the housing 2 flows through the housing 2 and is discharged to the outside via the exhaust port 6, as shown by arrow AF1.

[0069] The steam generator 11 and ejector 12 are installed at a higher position than the exhaust port 6. Most of the air drawn in from the intake port 4 is discharged to the outside through the exhaust port 6 without directly hitting the steam generator 11 and ejector 12, as indicated by arrows AF1 and AF2. The steam generator 11 and ejector 12 are not easily cooled by air. Also, warm air inside the housing 2 tends to accumulate around the steam generator 11 and ejector 12, which are located at the top of the housing 2. Heat exchange due to air cooling is less likely to occur in the steam generator 11, for example, the drive flow supplied from the steam generator 11 to the ejector 12 becomes more stable. Heat exchange due to air cooling is also less likely to occur in the ejector 12, for example, a decrease in the temperature of the drive flow and a reduction in the refrigerant discharge performance by the ejector 12 are avoided.

[0070] The above is a description of exemplary embodiments of the present disclosure. Embodiments of the present disclosure are not limited to those described above, and various modifications are possible within the scope of the technical idea of ​​the present disclosure. For example, embodiments of the present application include combinations of embodiments explicitly shown in the specification or obvious embodiments as appropriate. [Explanation of symbols]
