For example, "A and / or B" can represent: A exists alone, A and B exist simultaneously, or B exists alone. Furthermore, the character " / " in this document generally indicates that the associated objects are in an "or" relationship.

[0033] An embodiment of the present application provides a CDU cabinet 100 .

[0034] For ease of description, the length of the CDU cabinet 100 is defined as the X-axis, the width of the CDU cabinet 100 is defined as the Y-axis, and the height of the CDU cabinet 100 is defined as the Z-axis. The X-axis, Y-axis, and Z-axis directions are perpendicular to each other.

[0035] The directional terms such as “upper”, “lower”, “top”, “bottom”, “left”, “right”, “front” and “back” used in the description of the CDU cabinet 100 in the embodiment of the present application are mainly based on the CDU cabinet 100 in the attached Figure 1 The display orientation is explained in the figure, with the positive direction of the Z axis as the "top" and "upper", the negative direction of the Z axis as the "bottom" and "lower", the positive direction of the X axis as the "right", the negative direction of the X axis as the "left", the positive direction of the Y axis as the "back", and the negative direction of the Y axis as the "front". It does not constitute a limitation on the orientation of the CDU cabinet 100 in actual application scenarios.

[0036] See also Figure 1 and Figure 3 In an embodiment of the present application, the CDU cabinet 100 includes a cabinet body 110 and a CDU unit, and a ventilation window is provided on the cabinet body 110; the CDU unit is arranged in the cabinet body 110, and the CDU unit includes a water pump 120 and a pipeline assembly 140, and the water pump 120 is connected to the cabinet body 110 and / or the pipeline assembly 140 through a shock-absorbing structure.

[0037] In the technical solution of the present application, by providing ventilation windows on the cabinet 110, the heat dissipation requirements of the CDU cabinet 100 are met. By connecting the water pump 120 to the cabinet 110 and / or the pipe assembly 140 via a shock-absorbing structure, the operating noise of the CDU cabinet 100 can be effectively reduced. The operating noise of the CDU cabinet 100 is mainly generated by the vibration of the water pump 120. By connecting the water pump 120 to the cabinet 110 via a shock-absorbing structure, the present application can effectively suppress the resonance caused by direct contact between the water pump 120 and the cabinet 110, thereby reducing the vibration of the cabinet 110 caused by the vibration of the water pump 120. Moreover, by connecting the water pump 120 to the pipe assembly 140 via a shock-absorbing structure, the vibration of the pipe caused by the vibration of the water pump 120 can be reduced, thereby effectively reducing the operating noise of the CDU cabinet 100. The CDU cabinet 100 proposed in the technical solution of the present application can meet both heat dissipation requirements and noise reduction requirements, and can improve the user experience.

[0038] See also Figure 3 In the embodiment of the present application, the shock-absorbing structure includes a shock-absorbing seat (not shown in the figure), a load-bearing platform 112 is provided in the cabinet 110, the water pump 120 is provided on the load-bearing platform 112, and the shock-absorbing seat is clamped between the load-bearing platform 112 and the water pump 120.

[0039] Specifically, a base is provided at the lower end of the water pump 120, and the water pump 120 is mounted on the load-bearing platform 112 through the base, and the shock-absorbing seat is sandwiched between the base and the cabinet 110. A plurality of supporting legs are provided at the bottom of the base, and more commonly, four supporting legs are provided at the bottom of the base, and a shock-absorbing seat is provided between the supporting legs and the base, and the shock-absorbing seat and the supporting legs are provided in a one-to-one correspondence. The shock-absorbing seat can be integrally formed with the supporting legs / the load-bearing platform or formed separately.

[0040] It should be noted that when the support legs are made of shock-absorbing material, there is no need to provide a shock-absorbing seat between the support legs and the base, and the support legs can serve as the shock-absorbing seat.

[0041] Please continue reading Figure 3 In this embodiment of the present application, the shock-absorbing structure includes a telescopic tube 130, through which the inlet and outlet of the water pump 120 are connected to the pipeline assembly 140. The provision of the telescopic tube 130 at the inlet and outlet of the water pump 120 reduces the force exerted on the pipeline assembly 140 by the vibration of the water pump 120, thereby preventing deformation or damage to the pipeline caused by the vibration of the water pump 120.

[0042] In the embodiment of the present application, the telescopic tube 130 can be a metal bellows or a flange expansion joint or other telescopic pipe, and those skilled in the art can choose according to actual conditions.

[0043] In the embodiment of the present application, to further reduce the operating noise of the CDU cabinet 100, sound-absorbing cotton is provided on the inner walls of the cabinet body 110. Specifically, the sound-absorbing cotton can be applied to the front, rear, left, right, top, and bottom walls of the cabinet body 110, or selectively to certain walls depending on the actual situation.

[0044] See also Figure 1 In one embodiment, the plurality of ventilation windows include a first ventilation window 110a and a second ventilation window 110b. The cabinet 110 is further provided with a first fan (not shown), the first fan being provided corresponding to the second ventilation window 110b. In one specific embodiment, the first fan is an axial flow fan.

[0045] In the above embodiment, the first vents 110a are used for natural heat dissipation, and the second vents 110b are used for forced heat dissipation. When the heat output of the CDU unit is low and the temperature inside the cabinet 110 is low, the first fan is turned off, the first vents 110a are opened, and the second vents 110b can be opened or closed. The air inside and outside the cabinet 110 passes through the first vents 110a through natural convection heat exchange, thereby meeting the heat dissipation requirements of the CDU cabinet 100. When the heat generation of the CDU unit is high and the temperature inside the cabinet 110 is high, the natural convection heat exchange between the air inside the cabinet 110 and the outside air through the first ventilation window 110a alone cannot meet the heat dissipation requirements of the CDU cabinet 100. At this time, the first ventilation window 110a and the second ventilation window 110b need to be opened together, and the first fan is started. The first fan quickly blows out the hot air in the cabinet 110 through the second ventilation window 110b and quickly introduces cold air from the outside through the first ventilation window 110a, thereby improving the heat dissipation efficiency of the CDU cabinet 100.

[0046] In the above embodiment, the first ventilation window 110a and the second ventilation window 110b can be in a continuously open state. Of course, the first ventilation window 110a and the second ventilation window 110b can also be selectively opened and closed according to heat dissipation requirements, which is not limited in this embodiment of the present application.

[0047] See also Figure 2 and Figure 4In the above embodiment, the CDU unit further includes an electrical control box 150, which includes an electrical control body 151 and a heat sink 152 disposed on one side of the electrical control body 151. The electrical control body 151 contains various electrical components. The heat sink 152 is used to absorb heat generated by the electrical control body 151. A second fan is disposed within the heat sink 152. In one embodiment, the second fan is an axial flow fan. The first vent 110a is disposed on the side of the electrical control body 151 facing away from the heat sink 152, and the second vent 110b is disposed on the outlet side of the heat sink 152. The first fan is located between the outlet of the heat sink 152 and the second vent 110b. During operation, external cold air enters the cabinet 110 from the first ventilation window 110a, part of the cold air directly contacts the electric control body 151 to cool the electric control body 151, and the other part of the cold air is sucked into the radiator 152 by the second fan to exchange heat with the electric control body 151, and then is led out of the cabinet 110 from the second ventilation window 110b by the first fan.

[0048] In the CDU cabinet 100, the electrical control box 150 is one of the main sources of heat generation. In the above embodiment, by installing a second fan in the heat sink 152 of the electrical control box 150, the air flow rate in the heat sink 152 can be increased, thereby preventing excessive temperature rise from affecting the normal operation of the electrical components within the electrical control unit 151. Furthermore, by properly positioning the first and second ventilation windows 110a, 110b, the heat exchange area between the external cold air and the electrical control unit 151 can be increased, improving the heat dissipation efficiency of the electrical control unit 151 and, consequently, the overall heat dissipation efficiency of the CDU cabinet 100.

[0049] In the above embodiment, in detail, the electric control box 150 is disposed at the upper portion of the cabinet 110, the radiator 152 is disposed at the rear side of the electric control body 151, the outlet end of the radiator 152 faces upward and the inlet end faces downward, the first ventilation window 110a is disposed at the front side of the upper end of the cabinet 110, and the second ventilation window 110b is disposed at the top of the cabinet 110. In a specific embodiment, a door 111 is disposed at the front side of the cabinet 110, and the first ventilation window 110a is disposed at the upper portion of the door 111.

[0050] The water pump 120 is disposed at the lower portion of the cabinet 110. The closer the water pump 120 is to the first ventilation window 110a and the second ventilation window 110b, the easier it is for the operating noise of the water pump 120 to be transmitted from the cabinet 110. Therefore, by disposing the water pump 120 and the first ventilation window and the second ventilation window at the upper and lower portions of the cabinet 110, respectively, the noise of the water pump 120 can be prevented from spreading through the first ventilation window 110a and the second ventilation window 110b, thereby further reducing the operating noise of the CDU cabinet 100.

[0051] In the above embodiment, the plurality of ventilation windows further include a third ventilation window 110c, which is located on one side of the water pump 120 and is disposed on the lower sidewall of the cabinet 110. Providing the third ventilation window 110c on the side of the water pump 120 facilitates effective heat dissipation of the water pump 120.

[0052] It should be noted that the size of the third ventilation window 110c should not be too large and can be adjusted according to the size of the water pump 120. The smaller the size of the third ventilation window 110c, the less conducive it is to the transmission of the operating noise of the water pump 120, that is, the more conducive it is to noise reduction of the CDU cabinet 100.

[0053] Based on the above embodiment, in one embodiment, the number of the first ventilation windows 110a is multiple, and / or the number of the first fan and the number of the second ventilation windows 110b are both multiple. In one specific embodiment, the number of the first ventilation windows 110a and the number of the second ventilation windows 110b are both two, and the two first ventilation windows 110a / second ventilation windows 110b are arranged adjacent to each other along the X-axis direction.

[0054] In the above embodiment, it can be understood that the number of the first ventilation windows 110a / second ventilation windows 110b that are opened can be adjusted according to the heat dissipation requirements of the CDU cabinet 100, and this embodiment of the present application does not specifically limit this.

[0055] In the above embodiment, specifically, a plurality of first fans are correspondingly provided for one second ventilation window 110b.

[0056] In the above embodiment, the operating number and / or operating frequency of the first fan are adjustable.

[0057] In the above embodiment, the cabinet 110 is further provided with a temperature measuring device and a control module. The temperature measuring device is electrically connected to the control module. The temperature measuring device is used to measure the temperature of the target area in the cabinet 110. The control module is used to control the number of operations of the first fan according to the measurement result of the temperature measuring device. The control method is as follows:

[0058] Monitoring the temperature T of a target area in the cabinet 110;

[0059] If T<T0, the first fan is controlled not to work;

[0060] If T0≤T<T1, then control N1 units of the first fans to operate;

[0061] If T1≤T<T2, then control N2 units of the first fans to work;

[0062] If T n-1 ≤T<T n , then control N n The first wind turbine is working; wherein,

[0063] T0<T1<T2≤T n-1 <T n , N1<N2<N n ≤N.

[0064] Fan noise is also a source of noise in the CDU cabinet 100. At a given frequency, the more first fans are running, the louder the noise. In the above embodiment, the CDU cabinet 100 can activate an appropriate number of first fans based on its own cooling requirements. This effectively dissipates heat from the CDU cabinet 100 while reducing operating noise, improving operational performance, and achieving high energy efficiency.

[0065] In one embodiment, the control module is further configured to control the operating frequency of the first fan according to the measurement result of the temperature measuring device. The control method is as follows:

[0066] Monitoring the temperature F of a target area in the cabinet 110;

[0067] If F<F1, the first fan is controlled not to work;

[0068] If F1≤F<F2, then control the first fan to operate at the first frequency;

[0069] If F2≤F<F3, then control the first fan to operate at the second frequency;

[0070] If F n-1 ≤F<F n , then the first fan is controlled to operate at the nth frequency; wherein,

[0071] F0<F1<F2≤F n-1 <F n , the first frequency, the second frequency and the nth frequency increase sequentially.

[0072] The higher the operating frequency of the first fan, the greater the noise it generates. In the above embodiment, the CDU cabinet 100 can adjust the operating frequency of the first fan to an appropriate value based on its own heat dissipation requirements. This not only effectively dissipates heat for the CDU cabinet 100, but also reduces the operating noise of the CDU cabinet 100, improves the operating performance of the CDU cabinet 100, and achieves high efficiency and energy saving.

[0073] In the above embodiment, the target area is generally an area close to the average temperature in the cabinet 110, for example: the middle of the cabinet 110. Of course, those skilled in the art can also use other areas as target areas, and the embodiment of the present application does not specifically limit this.

[0074] In one embodiment, the operating frequency of the second fan is adjustable, and the control module is further used to control the operating frequency of the second fan. Generally speaking, the higher the temperature in the radiator 152, the higher the operating frequency of the second fan.

[0075] In one embodiment, the openings of the first and second ventilating windows 110a, 110b are adjustable, and the control module is further configured to control the openings of the first and second ventilating windows 110a, 110b. Fine-tuning the openings of the first and second ventilating windows 110a, 110b can further balance the heat dissipation and noise reduction effects of the CDU cabinet 100.

[0076] It is understandable that the cabinet 110 is further provided with an operation panel, which is electrically connected to the control module. In a specific embodiment, the operation panel is provided on the door 111 on the front side of the cabinet 110.

[0077] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
