Description

Technical Field

[0001] This utility model relates to the field of electrical control box technology, specifically to an electrical control box constant temperature system. Background Technology

[0002] Currently, in actual use, the circuit breakers and contactors in the air conditioner control box often experience a significant decrease in lifespan and capacity due to high temperatures and the temperature rise of the components themselves. This can lead to power outages and malfunctions in the unit as a whole due to the severe reduction in component capacity.

[0003] Currently, most solutions for heat dissipation in this type of electrical control box on the market involve increasing the heat dissipation area by opening windows in the structure or adding fans inside the control box. However, opening windows in the structure makes it more difficult to address issues such as waterproofing and insect prevention. Similarly, adding fans inside the control box increases the required area, which often means that the overall unit also needs to be larger.

Detailed Implementation

[0023] The present invention will be further described in conjunction with the following embodiments.

[0024] Depend on Figures 1 to 3 As can be seen, the electronically controlled box constant temperature system described in this embodiment includes a box body 2, a compressor 11, an evaporator 12, and a condenser 13; a first pipe 14 is provided between the evaporator 12 and the compressor 11; a second pipe 15 is provided between the condenser 13 and the compressor 11;

[0025] The temperature control system of the electric control box also includes heat dissipation pipes 3 and heating pipes 4, which are both disposed in the box body 2; the two ends of the heat dissipation pipes 3 are respectively connected to the evaporator 12 and the compressor 11; the two ends of the heating pipes 4 are respectively connected to the condenser 13 and the compressor 11.

[0026] Specifically, the temperature control system of the electric control box described in this embodiment uses a heat dissipation pipe 3 and a heating pipe 4 installed in the box body 2. The heat dissipation pipe 3 is located between the evaporator 12 and the compressor 11, and the heating pipe 4 is located between the condenser 13 and the compressor 11. When the temperature of the box body 2 exceeds the threshold, the refrigerant between the compressor 11, the evaporator 12, and the condenser 13 flows through the heat dissipation pipe 3, spreading the cold energy to the back of the box body 2 to cool down the interior of the box body 2. When the temperature of the box body 2 is below the threshold, the high-temperature gas between the compressor 11, the evaporator 12, and the condenser 13 flows through the heating pipe 4, spreading the heat to the back of the box body 2 to heat up the interior of the box body 2.

[0027] In this embodiment, the liquid refrigerant between the evaporator 12 and the compressor 11 is used to cool the box body 2 through the heat dissipation pipe 3 and the heating pipe 4, and the high temperature gas between the condenser 13 and the compressor 11 is used to heat the box body 2, so that the box body 2 can maintain a constant temperature. There is no need to open heat dissipation holes or add heat dissipation fans, nor is it necessary to add heat tracing tape at extremely low temperatures.

[0028] The temperature control system for an electronically controlled box described in this embodiment includes two heat dissipation pipes 3, which are respectively located on both sides of the box body 2. The heating pipe 4 is located in the middle of the box body 2. Specifically, since components with high heat generation are installed on both sides of the electronically controlled box in most cases, the temperature on both sides of the box body 2 is relatively high. Therefore, by placing the two heat dissipation pipes 3 on both sides of the box body 2, the temperature of the box body 2 can be controlled more evenly.

[0029] In the temperature control system of the electrically controlled box described in this embodiment, both the heating tube 4 and the heat dissipation tube 3 are U-shaped tubes. This arrangement increases the length of the heating tube 4 and the heat dissipation tube 3, enabling effective and sufficient heat exchange with the box body 2, and also facilitating the interconnection of pipes on the same side of the U-shaped tube.

[0030] In this embodiment, an electronically controlled temperature control system is described, wherein the heat dissipation pipe 3 is equipped with a first solenoid valve 31, and the heating pipe 4 is equipped with a second solenoid valve 41. This arrangement facilitates the control of the on / off state of both the heat dissipation pipe 3 and the heating pipe 4.

[0031] This embodiment describes an electrically controlled box temperature control system, in which a temperature sensor 5 is installed inside the box body 2; the first solenoid valve 31 and the second solenoid valve 41 are electrically connected to the temperature sensor 5. Specifically, by setting the temperature sensor 5, this embodiment can detect the temperature of the box body 2, thereby controlling the on / off state of the heat dissipation pipe 3 and the heating pipe 4 to ensure that the box body 2 is within a certain temperature range.

[0032] This embodiment describes an electrically controlled box temperature control system, in which a temperature control component is provided inside the box body 2; the temperature control component can be a thermostat; the first solenoid valve 31 and the second solenoid valve 41 are electrically connected to the temperature control component. Specifically, by setting the temperature control component, this embodiment can directly control the on / off state of the heat dissipation pipe 3 and the heating pipe 4 according to the set temperature range, ensuring that the box body 2 is within a certain temperature range.

[0033] In this embodiment, an electronically controlled box temperature control system is described, in which the heat dissipation pipe 3 and the heating pipe 4 are arranged parallel to each other on the back of the box body 2. This arrangement enables effective heat exchange with the box body 2.

[0034] The electrically controlled box temperature control system described in this embodiment includes a box body 2 with a first heat transfer module 61 and a second heat transfer module 62; a heat dissipation pipe 3 passes through the first heat transfer module 61; and a heating pipe 4 passes through the second heat transfer module 62. This arrangement increases the heat transfer area between the heating pipe 4 and the box body 2, as well as the heat dissipation pipe 3 and the box body 2, resulting in better and more uniform heat transfer.

[0035] In the electrically controlled box constant temperature system described in this embodiment, the cross-sectional shape of the first heat transfer module 61 and the second heat transfer module 62 are both rectangular; the width of the first heat transfer module 61 is greater than the width of the heat dissipation pipe 3; and the width of the second heat transfer module 62 is greater than the width of the heating pipe 4. This configuration further increases the heat transfer area between the heating pipe 4 and the box body 2, as well as the heat transfer area between the heat dissipation pipe 3 and the box body 2.

[0036] In the temperature control system of the electronic control box described in this embodiment, both the first heat transfer module 61 and the second heat transfer module 62 are copper blocks. Copper blocks have good thermal conductivity, enabling better heat transfer.

[0037] The temperature control system of the electrically controlled box described in this embodiment includes a heat-insulating outer shell for the box body 2; the first heat transfer module 61 and the second heat transfer module 62 are disposed inside the heat-insulating outer shell. The heat-insulating outer shell is not shown in the figure. The heat-insulating outer shell prevents the first heat transfer module 61 and the second heat transfer module 62 from direct contact with the outside environment, thereby reducing heat loss.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
