Description

Technical Field

[0001] The present invention relates to the technical field of thermal management systems and components thereof, and in particular to an electric control module installation structure of a liquid-cooled air conditioner, a liquid-cooled air conditioner and an energy storage system. Background Art

[0002] An energy storage system is a system used to store and release electrical energy. It involves the conversion between electrical energy and chemical energy, as well as the conversion between electrical energy and electrical energy. In the above process, a lot of heat will be generated. If the heat cannot be discharged in time, the temperature of the energy storage system will rise, bringing safety hazards, and thus affecting the performance, life and normal operation of the energy storage system.

[0003] In order to control the temperature of the energy storage system and improve the charging and discharging efficiency of the energy storage system, a thermal management system needs to be configured in the energy storage system to dissipate heat for the energy storage system.

[0004] Some types of energy storage systems (such as box-type energy storage systems and cabinet-type energy storage systems, etc.) have battery packs, power conversion devices (such as inverters, converters and power converters containing various power electronic devices, etc.) and controllers and other components integrated in the cabinet. In the prior art, this type of energy storage system is usually equipped with a liquid-cooled air conditioner as the core device of the thermal management system.

Since the cabinet of the energy storage system does not have enough space for installing the electric control box, the electric control box needs to be installed at the liquid-cooled air conditioner; in the prior art, the electric control box is installed inside the liquid-cooled air conditioner. When it is necessary to inspect, maintain and repair the electric control module, it is often necessary to disassemble the liquid-cooled air conditioner from the cabinet of the energy storage system to the ground, then disassemble the cover of the liquid-cooled air conditioner, and unscrew the fixing bolts of the electric control box (even in the above process, it is necessary to disassemble some components of the liquid-cooled air conditioner) before the components integrated in the electric control box can be inspected, maintained and repaired.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] This embodiment provides an electric control module installation structure for a liquid-cooled air conditioner, which is applied to a liquid-cooled air conditioner.

[0030] It should be noted that the chassis 1 is suitable for being installed in a cabinet of a cabinet-type device by means of screw fixation, bracket fixation, slot movable fixation, and guide rail movable fixation, and at least one side of the chassis 1 is exposed to the cabinet (for example, flush with the cabinet surface, or protruding from the cabinet surface).

[0031] The electronic control module 2 is used to provide functions such as power input, signal input and signal feedback for components such as the compressor, fan, electronic expansion valve, evaporative heat exchanger and liquid cooling module of the liquid-cooled air conditioner.

[0032] The chassis 1 is provided with at least one chassis panel 11. In fact, the chassis panel 11 is a side surface of the chassis 1. Since the chassis panel 11 can directly face the user and maintenance personnel, it is called the "chassis panel 11". In fact, the chassis panel 11 can be provided with structures such as air inlets, air outlets, operation panels and human-computer interfaces, or can be provided with only a flat surface. When the chassis 1 is installed in a cabinet, the chassis panel 11 is exposed on the surface of the cabinet (for example, flush with the cabinet surface, or protruding from the cabinet surface), so that the user and maintenance personnel can directly face the chassis panel 11.

[0033] An electric control module jack 111 is provided on the chassis panel 11 of the chassis 1 . In fact, the electric control module jack 111 is a square hole provided on the chassis panel 11 .

[0034] The electric control module 2 includes an electric control box 21 , an electric control module panel 22 disposed on one side of the electric control box 21 , and an electric control device 23 accommodated in the electric control box 21 .

[0035] Among them, the electric control box 21 is a square box body surrounded by several square steel plates, which is used to accommodate the electric control device 23; the electric control module panel 22 is a square steel plate installed on one side of the electric control box 21. Since the electric control module panel 22 can directly face the user and maintenance personnel, it is called "electric control module panel 22"; the electric control device 23 includes liquid-cooled air-conditioning controller, power electronic drivers (such as compressor frequency conversion drivers, special drivers for water pumps and fans, etc.), sensors and input / output interfaces (divided into power input / output interfaces and signal input / output interfaces) and other components, which are used to assume the actual functions of the electric control module 2.

[0036] In this embodiment, the electric control module panel 22 can be configured with structures such as buttons, indicator lights, operation panels, and human-computer interactions. The incoming lines of the above structures pass through the electric control module panel 22 and the electric control box 21, thereby being electrically and / or signal-connected with the electric control device 23; in other embodiments, the electric control module panel 22 can also be configured as only a flat surface.

[0037] The electric control box 21 of the electric control module 2 is suitable for being plugged into the electric control module socket 111 of the chassis 1 , and the electric control box 21 of the electric control module 2 is suitable for being pulled out from the electric control module socket 111 of the chassis 1 .

[0038] When the electric control box 21 of the electric control module 2 is plugged into the electric control module jack 111 of the chassis 1 , the electric control box 21 can be positioned in the chassis 1 , and the electric control module panel 22 can be positioned at the chassis panel 11 of the chassis 1 .

[0039] Furthermore, an electric control module guide rail 12 is configured in the chassis 1; when the electric control box 21 of the electric control module 2 is plugged into the electric control module socket 111 of the chassis 1, or when the electric control box 21 of the electric control module 2 is pulled out from the electric control module socket 111 of the chassis 1, the electric control box 21 of the electric control module 2 can slide along the electric control module guide rail 12.

In this embodiment, the width of the bottom bracket 121 is configured to adapt to the thickness of the electric control box 21, and then the two side guard arms 122 are respectively fixed on both sides of the bottom bracket 121 by welding or screwing, so as to obtain the electric control module guide rail 12.

[0041] Furthermore, the electric control module guide rail 12 also includes a rear baffle 123, which is arranged at the end of the electric control module guide rail 12.

[0042] Furthermore, a positioning pin 215 is arranged at the electric control box 21 of the electric control module 2. In fact, the positioning pin 215 is a pin body made of metal or elastic material (such as rubber and silicone) fixed on the surface of the electric control box 21; a positioning hole 1231 adapted to the positioning pin 215 is provided at the rear baffle 123 of the electric control module guide rail 12. In fact, the positioning hole 1231 is a circular hole opened at the rear baffle 123; when the electric control box 21 of the electric control module 2 is plugged into the electric control module jack 111 of the chassis 1, the positioning pin 215 of the electric control box 21 is plugged into the positioning hole 1231 of the rear baffle 123; in this embodiment, two groups of positioning pins 215 at the electric control box 21 and positioning holes 1231 at the rear baffle 123 are arranged.

[0043] The electric control box 21 is limited by the electric control module guide rail 12 and the rear baffle 123, and the positioning pin 215 at the electric control box 21 cooperates with the positioning hole 1231 at the rear baffle 123, so that when the electric control box 21 of the electric control module 2 is plugged into the electric control module jack 111 of the chassis 1, the electric control box 21 can be effectively positioned in the chassis 1.

[0044] Furthermore, a first screw hole 112 is provided at the chassis panel 11 of the chassis 1, and the first screw hole 112 is configured with a thread; a second screw hole 221 is provided at the electric control module panel 22 of the electric control module 2, and the second screw hole 221 may be configured with a thread or may not be configured with a thread; when the electric control box 21 of the electric control module 2 is plugged into the electric control module jack 111 of the chassis 1, the second screw hole 221 at the electric control module panel 22 and the first screw hole 112 at the chassis panel 11 are aligned with each other; after the screw passes through the second screw hole 221 at the electric control module panel 22, it is locked into the first screw hole 112 at the chassis panel 11, so that when the electric control box 21 of the electric control module 2 is plugged into the electric control module jack 111 of the chassis 1, the electric control module panel 22 can be effectively positioned at the chassis panel 11 of the chassis 1.

[0045] Specifically, the electric control box 21 includes a main box body 211, a box cover 212 that can be opened and closed relative to the main box body 211, and a movable lock 214 that can lock / unlock the main box body 211 and the box cover 212; wherein the main box body 211 is a square box body surrounded by several square steel plates and has an opening; the electric control device 23 of the electric control module 2 is accommodated and fixed in the main box body 211, and the electric control module panel 22 of the electric control module 2 is fixed on one side of the main box body 211; the box cover 212 is a steel cover plate, which can be adapted to the main box body 211, and the box cover 212 is hinged. It is pivotally connected to the main box body 211 so that the box cover 212 can be opened and closed relative to the main box body 211; it should be noted that the movable lock 214 includes a buckle 2141 configured at the main box body 211, and a buckle hook 2142 configured at the box cover 212. When the box cover 212 is closed, the main box body 211 and the box cover 212 can be locked by the movable lock 214 (that is, the buckle 2141 is buckled on the buckle hook 2142), and the movable lock 214 is unlocked (that is, the buckle 2141 is separated from the buckle hook 2142), so that the box cover 212 can be opened relative to the main box body 211.

[0046] Furthermore, a cable gland 213 is embedded in the main box body 211 of the electric control box 21, so that the cable of the electric control device 23 passes through the main box body 211 of the electric control box 21, and a certain degree of sealing performance is obtained at the cable passing position.

[0047] Furthermore, the surface of the electric control box 21 of the electric control module 2 is provided with heat dissipation fins 216; in the present embodiment, a plurality of heat dissipation fins 216 arranged in parallel are integrated on an aluminum alloy plate to form a heat dissipation module, the aluminum alloy plate of the heat dissipation module is fixed to the surface of the electric control box 21 by screws, and thermal conductive silicone grease is coated between the heat dissipation module and the electric control box 21; the heat dissipation module can absorb the heat of the electric control box 21 and dissipate it into the air through the heat dissipation fins 216 to control the temperature of the electric control box 21, and further control the temperature of the electric control device 23 in the electric control box 21.

[0048] After setting up the cabinet equipment, the chassis 1 of the liquid-cooled air conditioner is installed in the cabinet of the cabinet equipment by means of screw fixing, bracket fixing, slot movable fixing and guide rail movable fixing, so that the chassis panel 11 of the chassis 1 is exposed in the cabinet; the electric control box 21 of the electric control module 2 is plugged into the electric control module jack 111 of the chassis 1. At this time, the electric control box 21 is limited by the electric control module guide rail 12 and the rear baffle 123, and the positioning pin 215 at the electric control box 21 cooperates with the positioning hole 1231 at the rear baffle 123, which can effectively position the electric control box 21 in the chassis 1; the second screw hole 221 at the electric control module panel 22 is aligned with the first screw hole 112 at the chassis panel 11, and after the screw passes through the second screw hole 221 at the electric control module panel 22, it is locked into the first screw hole 112 at the chassis panel 11, which can effectively position the electric control module panel 22 at the chassis panel 11 of the chassis 1.

[0049] When it is necessary to inspect, maintain or repair the electric control module 2 (especially the electric control device 23), it is only necessary to unscrew the screws on the electric control module panel 22 to pull the entire electric control box 21 out of the chassis 1 (the process is guided by the electric control module guide rail 12), and then unlock the movable lock 214 (that is, the buckle 2141 is separated from the buckle hook 2142), and then open the box cover 212 to inspect, maintain or repair the electric control device 23 in the main box body 211; after the operation is completed, it is only necessary to close the box cover 212, lock the movable lock 214 (that is, the buckle 2141 is separated from the buckle hook 2142), and then remove the electric control device 23 in the main box body 211. 1 is buckled on the buckle hook 2142), and then the electric control box 21 is plugged into the electric control module jack 111 of the chassis 1 (this process is guided by the electric control module guide rail 12), until the electric control box 21 is limited by the electric control module guide rail 12 and the rear baffle 123, and the positioning pin 215 at the electric control box 21 is matched with the positioning hole 1231 at the rear baffle 123, and finally, the screws at the electric control module panel 22 are locked (that is, the screws pass through the second screw holes 221 at the electric control module panel 22 and are locked into the first screw holes 112 at the chassis panel 11), and the installation of the electric control module 2 is completed.
