[0002] The power consumption of distribution box varies due to various factors. Larger specifications and high-capacity distribution boxes usually consume relatively more power because they may contain more electrical components, thicker wires, and more complex circuit structures. For example, the distribution box for large industrial equipment requires high current and high voltage, so the internal circuit breaker, contactor and other components are also relatively large. These components generate some power consumption when working.
[0003] At the same time, there are factors that cause high energy consumption during the operation of the distribution box. For example, the ambient temperature directly affects the power consumption of the distribution box. In a high-temperature environment, the electrical components in the distribution box have difficulty dissipating heat, which can cause the component temperature to rise, increasing the resistance and increasing power loss. The load conditions caused by high temperature and high energy consumption can in turn reduce the service life of the components, creating a vicious cycle that increases the cost of use and maintenance.

[0028] Embodiment
[0029] Please refer to Figures 1-6 The utility model provides a kind of energy-saving power distribution box technical scheme: including power distribution box 10 and cooling energy -conserving device 20;
[0030] Power distribution box 10 is provided with cooling energy -conserving device 20, and cooling energy -conserving device 20 includes cooling liquid tank 201, heat conduction window 204, heat exchanger 205 and expansion heat dissipation pipeline 206;
[0031] The cooling liquid tank 201 is installed on the upper part of the rear side of the distribution box 10, and a circulating pump 202 is installed on the cooling liquid tank 201; the rear side of the bottom of the distribution box 10 is provided with a heat dissipation grille window 203;
[0032] The rear side of the inner cavity of the distribution box 10 is provided with a heat conduction window 204, which is embedded in the inner wall of the distribution box 10, and the heat conduction window 204 is uniformly provided with heat conduction fins, which are inclinedly arranged, and the heat conduction fins are provided with a gap therebetween, and the heat conduction fins are uniformly arranged with semiconductor refrigeration fins;
[0033] The rear side of the heat conduction window 204 is provided with a heat exchanger 205, and the inner cavity of the heat exchanger 205 is provided with an S-shaped channel, and the top of the S-shaped channel is connected to the water outlet of the cooling liquid tank 201;
[0034] The expansion heat dissipation pipeline 206 is a corrugated expansion pipeline, and adjacent expansion heat dissipation pipelines (206) are connected to each other, and each end of the expansion heat dissipation pipeline 206 has a connecting pipe, one connecting pipe is connected to the heat exchanger 205 upward, and the other connecting pipe is connected to the water inlet of the cooling liquid tank 201 after extension;
[0035] The expansion heat dissipation pipeline 206 is installed on the inner side of the heat dissipation grille window 203, which prolongs the passing time of the cooling liquid and expands the heat dissipation area to accelerate the heat dissipation of the cooling liquid;
[0036] One side of the heat exchanger 205 close to the heat conduction window 204 is a heat absorption surface, which is made of any one of an aluminum alloy solid heat absorption surface plate, a copper solid heat absorption surface plate and a ceramic solid heat absorption surface plate, and the heat absorption surface is in close contact with the heating end of the heat conduction fin;
[0037] The capacity of the heat exchanger 205 is equal to that of the expansion heat dissipation pipeline 206, and the capacity of the heat exchanger 205 and the expansion heat dissipation pipeline 206 is equal to two-thirds of the capacity of the cooling liquid tank 201; when the heat exchanger 205 and the expansion heat dissipation pipeline 206 are filled, the cooling liquid tank 201 retains 50% of the cooling liquid capacity;
[0038] The front side of the distribution box 10 is provided with a control panel, and the control panel is provided with a temperature sensor and a temperature sensor electrically connected thereto, and the temperature sensor is installed in the inner cavity of the distribution box 10 to detect the internal temperature change; the temperature sensor is electrically connected with the circulating pump 202;
[0039] The scheme provides a distribution box which saves electric energy and delays element loss by adjusting heat dissipation. First, the temperature sensor senses the internal temperature change and converts the temperature change into an electric signal output. The temperature sensor converts the temperature information into an electric signal and transmits it to the control chip;
[0040] The temperature sensor transmits an electrical signal to the regulating chip, which processes and analyzes the signal. The regulating chip usually contains an analog-to-digital converter (ADC) to convert the analog electrical signal into a digital signal for digital processing. Then, the regulating chip compares the current temperature value with the preset target temperature value.
[0041] According to the comparison result, the regulating chip generates a corresponding control signal to control the operation of the cooling and energy-saving device 20, including starting, stopping, and adjusting the flow rate.
[0042] For example, if the current temperature is high, the circulating pump 202 is started to inject cooling liquid from the cooling liquid tank 201 downward. The cooling liquid flows into the heat exchanger 205 through the pipeline. The heat exchanger 205 has a heat-absorbing surface on the side close to the inner cavity of the distribution box 10. Through heat transfer, it absorbs heat and exchanges heat with the internal cooling liquid, achieving the purpose of cooling the tank. The S-shaped channel in the heat exchanger 205 can extend the path and time of the cooling liquid, improving the heat exchange efficiency. Moreover, the S-shaped channel path can also reduce the overall weight and the amount of cooling liquid used compared to the full-filling mode.
[0043] The heated cooling liquid then flows into the expansion heat dissipation channel 206. The heated cooling liquid flows uniformly and dispersedly into the expansion heat dissipation channel 206. The expansion heat dissipation channel 206 is located at the heat dissipation grid window 203, and the heated cooling liquid is dissipated through natural diffusion. The expansion heat dissipation channel can quickly reduce the heat of the injected cooling liquid in a short time, achieving the purpose of rapid cooling by increasing the heat dissipation area. Water cooling can also reduce noise, achieving multiple purposes at once. The expansion heat dissipation channel 206 then draws the cooled cooling liquid from the other end through the circulating pump 202 into the cooling liquid tank 201 for recycling.
[0044] In actual use, the cooling liquid tank 201, the heat exchanger 205, and the expansion heat dissipation channel 206 are always filled to capacity. The heat exchanger 205 is in a full-filling state and can absorb heat generated inside in real time. The expansion heat dissipation channel 206 is in a full-filling state and generally receives heated cooling liquid exchanged from the heat exchanger 205 above. The cooling liquid tank 201 maintains one-third of its capacity, forming a heat exchange complement with the heat exchanger 205 and the expansion heat dissipation channel 206, and maintaining an effective cycle of heating, heat dissipation, and standby.
[0045] In addition, semiconductor refrigeration pieces are distributed on the heat-conducting fins. The principle is that when an electric current passes through a loop composed of different conductors, heat absorption and heat release phenomena occur at the junctions of different conductors with different current directions. The heat absorption end is located in the inner cavity of the distribution box 10, while the heat release end is attached to the heat exchanger 205, which dissipates heat through heat transfer.
[0046] Meanwhile, the semiconductor refrigerating sheet is integrated on a control module, the control module is electrically connected with the regulating chip, and the control module cooperates with the temperature reduction energy-saving device 20 according to the current temperature change condition and adjusts the control output in real time, so as to keep the temperature in the set target temperature range.
[0047] The regulating chip generates the control output according to the difference between the current temperature and the target temperature in a certain proportion, and adjusts the control output according to the rate of temperature change. When the rate of temperature change is fast, it indicates that the system may be disturbed or in the process of rapid temperature rise and fall, so the regulating chip adjusts the control output in advance to inhibit the rapid change of the temperature and improve the stability and response speed of the system. By comprehensively using proportional, integral and differential control, the regulating chip can more accurately adjust the temperature to quickly and stably reach the target value. The chip control part is the prior art, and will not be described in detail here.
