Description

TECHNICAL FIELD

[0001] The utility model relates to vertical energy storage liquid cooling air conditioning technical field, especially vertical energy storage liquid cooling air conditioning's microchannel heat exchanger fixed structure of a kind of. BACKGROUND

[0002] In today's energy storage technology field, with the increasing power density of energy storage system and the increasingly diversified application scenarios, the requirements for the heat dissipation system are also increasingly stringent. As a key heat dissipation component in the energy storage equipment, the performance of the energy storage liquid cooling air conditioner directly affects the stability and reliability of the entire energy storage system.

[0003] Traditional energy storage air conditioners, especially those designed for vertical use, face many challenges in the pursuit of compact layout. On the one hand, to adapt to different installation space limitations, the overall size of the equipment needs to be minimized to achieve higher space utilization, which requires close arrangement of various components and design in a compact direction. However, on the other hand, as the core heat exchange component, the microchannel heat exchanger's heat exchange performance is closely related to the heat exchange area. A large enough heat exchange area is crucial to ensure efficient heat exchange, and only then can the refrigerant be efficiently condensed in the microchannel heat exchanger.

[0004] Past fixed structure designs often compromise one aspect for another. When trying to reduce the size of the cabinet to achieve a compact design, the heat exchange area of the microchannel heat exchanger is difficult to guarantee, and it is usually forced to be reduced, resulting in a significant reduction in heat exchange efficiency. Conversely, if the heat exchange area of the microchannel heat exchanger is prioritized, the entire air conditioning device will be bulky and cannot meet the space requirements of some application scenarios, such as narrow energy storage cabinets. Moreover, in traditional layouts, the microchannel heat exchanger is usually placed vertically or horizontally, which does not fully utilize the limited three-dimensional space inside the cabinet, and the ventilation path is not optimized, further limiting the heat exchange effect. It is difficult to balance the two key requirements of compactness and high efficiency heat exchange, and it is difficult to meet the needs of the rapid development of modern energy storage industry.

[0005] In summary, there is an urgent need for an innovative microchannel heat exchanger fixing structure for vertical energy storage liquid cooling air conditioners that can achieve compact design while ensuring that the microchannel heat exchanger has sufficient heat exchange area to improve the heat dissipation performance of the entire vertical liquid cooling air conditioner and even the energy storage system.

DETAILED DESCRIPTION

[0021] The vertical energy storage liquid cooling air conditioner micro-channel heat exchanger fixing structure is provided, in order to make the purpose, technical scheme and effect of the utility model more clear and definite, the utility model is further explained in detail below with reference to the drawings and examples. It should be understood that the specific examples described herein are only used to explain the utility model, and are not used to limit the protection scope of the utility model.

[0022] Please refer to Figures 1 to 3The utility model provides a kind of microchannel heat exchanger fixed structure of vertical energy storage liquid cooling air conditioner, including rectangular case 1, vertical frame fixed in case 1, microchannel heat exchanger 2 is vertically arranged on vertical frame, the side surface of case 1 is equipped with first ventilation net 11, and the other side surface is equipped with second ventilation net 12, the width of microchannel heat exchanger 2 is greater than the width of case 1, under the planar projection, microchannel heat exchanger 2 is inclined and located between first ventilation net 11 and second ventilation net 12.

[0023] First, rectangular case 1 as basic bearing component, provide physical protection and structural support for the whole device, limit the installation boundary of internal components, ensure that each component operates in a relatively stable space environment.Case 1 fixed vertical frame, with accurate positioning and stable support function, its rigid structure can reliably bear microchannel heat exchanger 2 vertically on it, avoid displacement or loosening of heat exchanger due to vibration, fluid impact and other external factors during operation, protect the stability and continuity of heat exchange process.

[0024] Further, first ventilation net 11 and second ventilation net 12 are respectively arranged on both sides of case 1 to build a key air flow path.First ventilation net 11 as air inlet, fan can guide external cold air to flow smoothly into the internal space of case 1;Second ventilation net 12 as air outlet, to make hot air after heat exchange in case 1 orderly discharged.This in-out ventilation design creates necessary air flow environment for heat transfer, so that heat can be transferred efficiently with air medium.

[0025] Especially key is the innovative layout design of microchannel heat exchanger 2.The width of microchannel heat exchanger 2 is greater than the width of case 1, and it is inclined and located between two ventilation nets under the planar projection.When air conditioning system operates, refrigerant circulates in the small channel inside microchannel heat exchanger 2, carrying a lot of heat.Due to its inclined angle, cold air enters case 1 from first ventilation net 11, and is no longer simply linear flow, but is guided and divided along the inclined surface of microchannel heat exchanger 2, greatly increasing the contact area and contact time of cold air and heat exchanger.Cold air closely adheres to the surface of heat exchanger, fully absorbs heat, and then hot air carrying heat is discharged from second ventilation net 12, so as to realize continuous and efficient heat exchange process, ensure that refrigerant is quickly condensed in microchannel heat exchanger 2, and achieve excellent heat dissipation efficiency.

[0026] The micro-channel heat exchanger fixing structure of the vertical energy storage liquid cooling air conditioner has the following advantages: on the one hand, the internal structure of the machine case 1 is reasonably planned, the vertical frame is used to accurately fix the components, the components are closely arranged, the overall size of the equipment is effectively reduced, the space utilization rate is greatly improved, and various strict installation space limitations can be flexibly adapted; on the other hand, even when a compact design is pursued, the micro-channel heat exchanger 2 is provided with a unique inclined layout, the internal three-dimensional space of the machine case 1 is ingeniously utilized, the volume of the machine case 1 does not need to be additionally enlarged, the sufficient heat exchange area can be ensured, and the perfect balance between space utilization and heat exchange performance is realized.

[0027] Specifically, the vertical frame comprises an outer frame 3 fixedly connected with the machine case 1 and an inner frame 4 detachably arranged in the outer frame 3, and the micro-channel heat exchanger 2 is detachably arranged on the inner frame 4. In the installation process, the inner frame 4 is first fixed on the outer frame 3, and then the micro-channel heat exchanger 2 is installed on the inner frame 4, so that the installation problem caused by component interference is effectively avoided. If the conventional installation mode simultaneously processes multiple components, the micro-channel heat exchanger 2 often blocks the connecting part of the outer frame 3 and the inner frame 4, so that the worker cannot accurately position the screw hole, and the screw tightening operation is blocked, which not only consumes a lot of time for adjusting the position of the components, but also easily causes problems such as misinstallation and missing installation. By using the step-by-step installation method provided by the utility model, the worker first focuses on the fixation of the outer frame 3 and the inner frame 4, at this time, the operation space is wide, the connection operation such as screw tightening can be clearly and conveniently completed, the connection is firm and accurate, and a solid foundation is laid for the smooth installation of the micro-channel heat exchanger 2.

[0028] Further, the outer frame 3 comprises a right-angled triangular plate 31 located at the top of the machine case 1 and a vertical plate strip 32 connected with a sharp corner of the right-angled triangular plate 31, and the bottom end of the vertical plate strip 32 is fixedly connected with the inner bottom surface of the machine case 1. The outer frame 3 ingeniously utilizes the stability principle of the triangle. The right-angled triangular plate 31 plays a key role in horizontal support and positioning at the top of the machine case 1, disperses the pressure borne by the machine case 1, and prevents the top of the machine case 1 from deforming. The bottom end of the vertical plate strip 32 is fixedly connected with the inner bottom surface of the machine case 1 and forms a stable three-dimensional support structure with the right-angled triangular plate 31, a solid defense line is constructed from the top to the bottom of the machine case 1, external force interference such as vibration and impact during equipment operation is effectively resisted, a stable and reliable bearing foundation is provided for the inner frame 4 and the micro-channel heat exchanger 2, and the long-term stable operation of the entire air conditioner system is ensured.

[0029] In order to fully tap the oblique space inside the case 1, the inner frame 4 is correspondingly arranged below the hypotenuse of the right triangle plate 31. Compared with the traditional square frame layout, this design breaks the convention and transforms the originally idle or difficult-to-use area below the hypotenuse into a key component placement space according to the geometric shape characteristics of the case 1, avoiding the waste of internal space, enabling the micro-channel heat exchanger 2 to be arranged in a more compact and reasonable manner, and securing more installation and heat exchange space for the micro-channel heat exchanger 2 without increasing the overall volume of the case 1, thereby improving the utilization rate of unit space and meeting the trend of miniaturization and intensification of energy storage equipment.

[0030] Specifically, the inner frame 4 includes a vertical panel 41 with a ventilation opening, an upper turning edge 42, a lower turning edge 43, a left turning edge 44, and a right turning edge 45 arranged at the edge of the vertical panel 41, at least two first nuts 51 are welded on the upper turning edge 42, and the right triangle plate 31 is provided with first mounting holes corresponding to the number of the first nuts 51, and first screws 52 are connected to the first nuts 51 after passing through the first mounting holes. The upper turning edge 42, the lower turning edge 43, the left turning edge 44, and the right turning edge 45 carefully designed at the edge of the vertical panel 41 of the inner frame 4 build a complete and closed structure contour for the inner frame 4 itself, not only strengthen the rigidity of the vertical panel 41, but also provide a precise positioning reference for the subsequent connection with the outer frame 3. The tight connection of the upper turning edge 42 and the right triangle plate 31 realizes the highly accurate and stable assembly between the inner frame 4 and the outer frame 3. This tightly fitted connection ensures that the inner frame 4 will not displace or shake during equipment operation, laying a solid foundation for stable and efficient work of the micro-channel heat exchanger 2.

[0031] Further, the lower turning edge 43 is provided with at least two second mounting holes 53, and the inner bottom wall of the case 1 is provided with second nuts corresponding to the number of the second mounting holes 53, and second screws 54 are connected to the second nuts after passing through the second mounting holes 53. Through the connection design of the lower turning edge 43 and the inner bottom wall of the case 1, additional support force is provided for the inner frame 4 in the vertical direction of the case 1. When the equipment is running, especially when facing vibration, impact, and other working conditions, at least two second screws 54 pass through the second mounting holes 53 of the lower turning edge 43 and are tightly connected with the second nuts of the inner bottom wall of the case 1, forming a stable vertical support structure, effectively preventing the inner frame 4 from shaking or displacing up and down, and further ensuring the stability of the micro-channel heat exchanger 2 carried thereon, so that the entire energy storage liquid cooling air conditioning system can run reliably in complex working environments.

[0032] Further, at least two third nuts 55 are welded on the left flange 44, and the cabinet 1 is provided with third mounting holes corresponding to the number of the second nuts, and third screws 56 are connected with the third nuts 55 after passing through the third mounting holes. The at least two third nuts 55 on the left flange 44 and the corresponding third mounting holes on the cabinet 1 are connected by the third screws 56, which form a complementary connection with the lower flange 43 and the bottom of the cabinet 1, providing reliable lateral support for the inner frame 4 from the left side of the cabinet 1. This multi-directional fixing method ensures that the inner frame 4 does not shake or deviate left or right inside the cabinet 1, and even when the device is subjected to lateral impact force, it can still be stably fixed in the predetermined position, ensuring the stable operation of the micro-channel heat exchanger 2, thereby maintaining the stability and reliability of the entire energy storage liquid cooling air conditioning heat dissipation system.

[0033] In order to realize the detachable connection of the micro-channel heat exchanger 2, the ventilation port is located in the middle of the vertical panel 41, and a fourth nut is welded on the vertical panel 41 above the ventilation port, and a fifth nut is welded on the vertical panel 41 below the ventilation port. The top and bottom of the micro-channel heat exchanger 2 are respectively provided with an upper buckle 21 and a lower buckle 22, the upper buckle 21 is fixed on the vertical panel 41 by cooperating with the fourth nut through a fourth screw 57, and the lower buckle 22 is fixed on the vertical panel 41 by cooperating with the fifth nut through a fifth screw 58. The design of the ventilation port in the middle of the vertical panel 41 enables cold air to flow accurately and smoothly from the ventilation port to the core heat exchange area of the micro-channel heat exchanger 2. When external cold air enters the cabinet 1, it does not need to take a detour and directly reaches the micro-channel heat exchanger 2, maximizing the cooling efficiency of the airflow, accelerating the condensation process of the refrigerant in the micro-channel heat exchanger 2, improving the heat exchange efficiency, and ensuring that the energy storage liquid cooling air conditioner can efficiently cope with the large amount of heat generated by the energy storage system, maintaining stable operation of the system.

[0034] The micro-channel heat exchanger 2 is fixed by cooperating the upper buckle 21 at the top with the fourth nut above the ventilation port on the vertical panel 41, and the lower buckle 22 at the bottom with the fifth nut below the ventilation port, forming a stable support structure at the top and bottom. This structure effectively prevents the micro-channel heat exchanger 2 from shifting, shaking or even falling due to vibration, fluid impact and other factors during operation, ensuring that the heat exchanger is always in the best working position and continuously and stably performs the heat exchange function, laying a solid foundation for the reliability of the entire heat dissipation system.

[0035] Preferably, the vertical panel 41 is provided with a plurality of wire holes 46, and a wire protection ring 6 is arranged at each wire hole 46. The plurality of wire holes 46 of the vertical panel 41 in combination with the wire protection ring 6 provide a neat and orderly path for various cables inside the cabinet 1. During the operation of the energy storage liquid cooling air conditioner, various lines such as power lines, signal lines and control lines are crisscrossed, and if there is no special wire routing channel, the cables are easy to be entangled and rubbed with each other, which not only affects the appearance, but also causes the outer skin of the line to be damaged, resulting in short circuit, signal interference and other serious faults. The wire protection ring 6 can effectively constrain the cable, avoid direct contact with the edge of the wire hole 46, prevent the cable from being damaged due to long-term friction, prolong the service life of the cable, and ensure the stability and reliability of power transmission and signal transmission.
