[0043] The application proposes a closed energy-saving thermal management device and method applied to a base station cabinet, which can control the thermal management work in real time according to the temperature in the base station cabinet 1, and realize the effective combination of the heat pipe cooling system, the fan cooling system and the thermoelectric refrigeration system. This thermal management method and device can effectively solve the problems of dust and moisture interference, have small load and low energy consumption, and are beneficial to the operation and heat dissipation of the equipment.

[0044] The heat pipe heat exchanger 2 has the advantages of energy saving, environmental protection, high space utilization rate and high reliability. Compared with the air conditioning cooling system, the energy consumption of the heat pipe heat exchange system is greatly reduced; compared with the fan cooling system, the heat pipe heat exchange system can effectively solve the problems of dust and moisture interference. The thermoelectric refrigerator 3 can realize refrigeration effect at a lower temperature difference and energy consumption, so it has higher refrigeration efficiency and less energy waste, and has the characteristics of energy saving and environmental protection.

[0045] A closed energy-saving thermal management device applied to a base station cabinet, which comprises a base station cabinet 1 and an integrated thermal management system, and a dividing plate 11 is vertically arranged in the base station cabinet 1, the dividing plate 11 divides the base station cabinet 1 into two chambers, which are a first chamber and a second chamber, wherein a rack is arranged in the first chamber, and a base station body 8 is placed on the rack, and a heat pipe heat exchanger 2 for heat exchange with the base station body 8 is arranged in the second chamber.

[0046] As shown in Figure 1 The integrated thermal management system comprises:

[0047] A temperature sensor 7 is arranged in the first chamber and close to the base station body 8, and is used for monitoring the temperature of the base station body 8 in real time; preferably, it is installed on the top of the first chamber;

[0048] A first fan 4 is rotatably arranged on the sealing plate, and the rotation of the first fan 4 makes the air in the first chamber circulate and exchange heat with the second chamber;

[0049] The heat pipe heat exchanger 2 is located in the second chamber and includes a heat pipe. A working medium flows inside the heat pipe. The heat pipe includes an evaporation section and a condensation section. The evaporation section is located near the first fan 4. A first window for heat exchange with the outside is provided on the side wall of the second chamber near the condensation section.

[0050] The thermoelectric cooler 3 includes a thermoelectric cooling plate 16 vertically mounted on a sealing plate. The cold end of the thermoelectric cooling plate 16 is located in a first chamber, and the hot end is located in a second chamber. A second window for heat exchange with the outside is provided on the side wall of the second chamber near the hot end.

[0051] A power supply, located in the first chamber, is used to power the temperature sensor 7, the first fan 4, and the thermoelectric cooler 3.

[0052] The control box 21 is located outside the base station cabinet 1. The control box 21 is connected to the temperature sensor 7, the first fan 4, and the thermoelectric cooler 3 respectively, and is used to control the temperature sensor 7, the first fan 4, and the thermoelectric cooler 3 respectively.

[0053] Specifically, such as Figure 2 As shown, the heat pipe heat exchanger 2 includes heat pipes, which are welded to the second chamber via a waist plate 15.

[0054] The heat pipe contains a suitable amount of working medium and includes an evaporator section tube bundle 12 and a condenser section tube bundle 13. The evaporator section tube bundle 12 is located near the first fan 4, while the condenser section tube bundle 13 is located near the side wall of the second chamber, where a first ventilation window is provided. The evaporator section tube bundle 12 and the condenser section tube bundle 13 are directly connected, and fins 14 are uniformly welded onto both the evaporator section tube bundle 12 and the condenser section tube bundle 13. The heat pipe can be a two-phase closed thermosiphon, a gravity-assisted heat pipe, a split heat pipe, an electrohydrodynamic heat pipe, a magnetohydrodynamic heat pipe, or a permeation heat pipe, as long as it achieves the purpose of this invention.

[0055] Specifically, such as Figure 3 As shown, the thermoelectric cooler 3 includes a thermoelectric cooling element 16, which is a heat transfer device. It is typically composed of an N-type semiconductor material and a P-type semiconductor material connected together. When current flows through the thermocouple pair formed by the N-type and P-type semiconductor materials, heat transfer occurs between the two ends, creating a temperature difference that forms a cold end and a hot end at the two ends of the thermoelectric cooler 16. The cold end of the thermoelectric cooler 16 is located in the first chamber, close to the base station cabinet 1 body, while the hot end is located in the second chamber. A second window for heat exchange with the outside is provided on the side wall of the second chamber near the hot end.

[0056] But the semiconductor itself exists resistance when the current through the semiconductor will generate heat, thereby affecting heat transfer. And the heat between the two polar plate will also be through air and semiconductor material itself reverse heat transfer. When the cold and hot end to a certain temperature difference, the amount of the two heat transfer is equal, when a balance point is reached, the positive and negative heat transfer offset each other, at this time the cold and hot end temperature will not continue to change.

[0057] In order to achieve lower temperature, can take the heat dissipation and so on to reduce the temperature of the hot end to achieve. So in the hot end of thermoelectric refrigeration piece 16 is connected with the first base 17, the first base 17 is fixedly provided with the hot end fin heat sink 18, through the installation of hot end fin heat sink 18 in the hot end, can accelerate the heat dissipation of thermoelectric refrigeration piece 16 hot end.

[0058] In addition, in order to improve the heat exchange efficiency of the cold end of thermoelectric refrigeration piece 16, the second base 19 is arranged at the cold end, and the cold end fin heat sink 20 is fixedly arranged on the second base 19.

[0059] As shown in Figure 4 In order to further improve the heat exchange efficiency of the condenser section of the heat pipe in the heat pipe heat exchanger 2 and the outside, and the heat exchange efficiency of the hot end of the thermoelectric refrigerator 3 and the outside, the second fan 5 is rotatably arranged in the first window, and the third fan 6 is rotatably connected in the second window.

[0060] In order to reduce the dust and rainwater entering the base station cabinet 1, the baffle device is arranged outside the second chamber at the positions of the second fan 5 and the third fan 6, and the baffle device is any one of the louver 9 and the dustproof filter screen 10.

[0061] In order to reduce the dust and moisture in the second chamber from entering the first chamber, the setting position of the first fan 4 should avoid being arranged opposite to the second fan 5 and the third fan 6, and preferably the first fan 4 is arranged at the lower part of the partition plate 11, and the second fan 5 and the third fan 6 are arranged at the upper part of the side wall of the second chamber.

[0062] In addition, the dustproof filter screen 10 is also arranged on both sides of the partition plate 11 at the position of the first fan 4, for preventing the dust in the second chamber from entering the first chamber and then entering the base station cabinet 1.

[0063] Based on the closed energy-saving heat management device applied to the base station cabinet 1, a heat management method applied to the base station cabinet is generated, which specifically includes the following steps:

[0064] S1, parameter presetting, setting temperature control parameters T0 and T1 in the control box 21, wherein T0>T1;

[0065] S2, heat exchange management, the temperature sensor 7 collects temperature information in the first chamber, and transmits the temperature information to the control box 21, the collected temperature information is compared with the temperature control parameters T0 and T1 set in the control box 21, to start or close the second fan 5, the third fan 6 and the thermoelectric refrigerator 3, to realize the heat exchange management in the base station cabinet 1;

[0066] The heat exchange management specifically includes the following steps:

[0067] When the temperature information T collected by the temperature sensor 7 i ≥T0, the control box 21 sends a control signal to the second fan 5, and the second fan 5 starts; if the second fan 5 runs for t1 time, the temperature information T collected by the temperature sensor 7 i Still greater than T0, the control box 21 sends control signals to the third fan 6 and the thermoelectric refrigerator 3 respectively, and then the third fan 6 and the thermoelectric refrigerator 3 start;

[0068] When the temperature information T collected by the temperature sensor 7 i , wherein T1≤T i <T0; the control box 21 sends control signals to the second fan 5, the third fan 6 and the thermoelectric refrigerator 3 respectively, the second fan 5 starts, the second fan 5 runs for t2 time, and the temperature information T collected by the temperature sensor 7 i , wherein T1≤T i <T0, the third fan 6 and the thermoelectric refrigerator 3 are closed;

[0069] When the temperature information T collected by the temperature sensor 7 i <T1, the control box 21 sends control signals to the second fan 5, the third fan 6 and the thermoelectric refrigerator 3 respectively, and the second fan 5, the third fan 6 and the thermoelectric refrigerator 3 are all closed.

[0070] During the whole heat dissipation process, the first fan 4 always keeps running state.

[0071] Specifically, by effectively combining the heat pipe heat exchanger 2, the fan cooling system and the thermoelectric refrigerator 3, the embodiment provides the following heat management working method;

[0072] The preset temperature control parameters T0 in the temperature sensor 7 are 50℃, 60℃ or 70℃, and the preset temperature control parameters T1 are 30℃, 35℃, 40℃ and 45℃.

[0073] When the temperature detected by the temperature sensor 7 is higher than the temperature control parameter T0 (e.g. 50℃), the control box sends a command to the second fan, and the second fan starts to run. However, the second fan runs for a period of time t1, which can be set to 10 seconds, 20 seconds, 30 seconds or even 60 seconds, and preferably t1 is 30 seconds. If the temperature detected by the temperature sensor 7 is still higher than the temperature control parameter T0 (e.g. 50℃) after 30 seconds, the control box sends a command to the thermoelectric refrigeration piece 16 and the third fan 6, and the thermoelectric refrigeration piece 16 and the third fan 6 start to run simultaneously.

[0074] When the temperature detected by the temperature sensor 7 is T i wherein T1≤T i <T0, preferably T1 is 30℃, the control box sends a command to the second fan, and the second fan starts to run. However, the second fan runs for a period of time t2, which can be set to 10 seconds, 20 seconds, 30 seconds or even 60 seconds, and preferably t2 is 30 seconds. If the temperature detected by the temperature sensor 7 is still T i wherein T1≤T i <T0, the thermoelectric refrigeration piece 16 and the third fan 6 are turned off.

[0075] The purpose of setting t1 and t2 is to ensure that the heat exchange of the base station cabinet is good, the temperature in the base station cabinet is maintained within a corresponding range, and energy consumption is saved.

[0076] When the temperature detected by the temperature sensor 7 is lower than T i ≤T1 (30℃), the second fan 5 is turned off. According to the change of the temperature in the cabinet, the embodiment can realize three working modes:

[0077] Embodiment one: the heat pipe heat exchanger and the thermoelectric refrigeration piece work simultaneously.

[0078] In hot summer, when the heat load in the base station cabinet 1 is large, and the temperature detected by the temperature sensor 7 is higher than 50℃, the control box 21 controls the second fan 5 to be in a running state. After the second fan 5 runs for 30 seconds, if the temperature detected by the temperature sensor 7 is still higher than 50℃, the control box 21 sends a command to the second fan 5 and the thermoelectric refrigeration piece 16, and the second fan 5 and the thermoelectric refrigeration piece 16 start to run.

[0079] Work flow: The first fan 4 makes the air in the cabinet form an internal circulation, to avoid local overheating while making the air in the base station cabinet 1 and the heat pipe heat exchanger 2 form a forced convection, the evaporation section pipe bundle 12 of the heat pipe heat exchanger 2 evaporates the working medium in the heat pipe after absorbing the heat in the base station cabinet 1, the steam moves to the condensation section pipe bundle 13 of the heat pipe, the second fan 5 cools the steam after the steam reaches the condensation section pipe bundle 13 of the heat pipe, the steam liquefies back to the evaporation section pipe bundle 12 of the heat pipe, and so on, the heat in the air in the base station cabinet 1 is taken to the external environment. Because in the hot summer, the heat load in the base station cabinet is large, the heat pipe heat exchanger 2 takes away limited heat, and the thermoelectric refrigerator 3 needs to assist in cooling; there is a temperature difference between the inside and outside of the cabinet, and the thermoelectric refrigerator 3 has different thermoelectric characteristics due to the different materials at the two ends of the thermoelectric refrigeration piece 16, so that an electromotive force appears at the two ends of the thermocouple, and a current flows in the external circuit, thereby transferring heat from the high-temperature end (the inside of the cabinet) to the low-temperature end (the outside of the cabinet), realizing refrigeration. The cold end fin radiator 20 of the cold end of the thermoelectric refrigerator 3 enhances the refrigeration performance of the thermoelectric refrigeration piece, and the hot end fin radiator 18 of the hot end enhances the heat dissipation of the thermoelectric refrigerator 3 itself, reducing additional power consumption.

[0080] Example two, single heat pipe heat exchanger working mode;

[0081] In the transition season, when the temperature detected by the temperature sensor 7 is higher than 30℃ and lower than 50℃, the control box 21 respectively sends instructions to the second fan 5, the thermoelectric refrigeration piece 16 and the third fan 6;

[0082] The control box 21 controls the second fan 5 to be in the running state, and after the second fan 5 runs for 30 seconds, when the temperature detected by the temperature sensor 7 is still higher than 30℃ and lower than 50℃, the control box 21 controls the thermoelectric refrigeration piece 16 and the third fan 6 to be closed.

[0083] Work flow: The first fan 4 makes the air in the cabinet form an internal circulation, to avoid local overheating while making the air in the base station cabinet 1 and the heat pipe heat exchanger 2 form a forced convection, the evaporation section pipe bundle 12 of the heat pipe heat exchanger 2 evaporates the working medium in the heat pipe after absorbing the heat in the base station cabinet 1, the steam moves to the condensation section pipe bundle 13 of the heat pipe, the second fan 5 cools the steam after the steam reaches the condensation section pipe bundle 13 of the heat pipe, the steam liquefies back to the evaporation section pipe bundle 12 of the heat pipe, and so on, the heat in the air in the base station cabinet 1 is taken to the external environment. Because in the transition season, the environment temperature is relatively low, the additional cooling of the thermoelectric refrigerator 3 is not needed, greatly reducing the energy consumption.

[0084] Example three, base station cabinet heat transfer working mode;

[0085] In the cold winter, when the temperature detected by the temperature sensor 7 is lower than 30℃, the control box 21 respectively controls the third fan, the thermoelectric refrigeration piece 16 and the third fan 6 to be closed.

[0086] Workflow: The first fan 4 makes the air in the base station cabinet form an internal circulation, avoids local overheating, and forms forced convection between the air in the base station cabinet 1 and the heat pipe heat exchanger 2. The working medium in the heat pipe evaporates after the evaporation section pipe bundle 12 of the heat pipe heat exchanger 2 absorbs heat in the base station cabinet. The steam moves to the condensation section pipe bundle 13 of the heat pipe. After the steam reaches the condensation section pipe bundle 13 of the heat pipe, the steam can be cooled only by natural convection. The steam liquefies back to the evaporation section pipe bundle 12 of the heat pipe. In this way, the heat in the air in the base station cabinet 1 is taken to the external environment. Because the ambient temperature is relatively low in cold winter, the second fan 5 is not needed to cool the condensation section pipe bundle 13. The energy consumption is reduced again.

[0087] During the entire heat exchange process, the first fan 4 is always in operation to ensure that the air in the base station cabinet 1 forms an internal circulation, avoiding local overheating of the base station body.

[0088] As can be known from the description of the above embodiment, the application can effectively maintain the temperature in the base station cabinet 1, meet the temperature range specified in the national GB / T51216-2017 “Mobile Communication Base Station Engineering Energy Saving Technology Standard”, and will not appear the local high temperature alarm phenomenon of the equipment. Secondly, the application adopts heat pipe technology and thermoelectric refrigeration technology. When the load in the base station cabinet 1 is small, only the heat pipe heat exchanger 2 is used for cooling. When the load in the base station cabinet 1 is large, the heat pipe heat exchanger 2 and the thermoelectric refrigerator 3 are started at the same time for cooling. The energy saving effect is very significant. The problem of serious over-standard of cleanliness in some existing base station cabinets is effectively solved, which is conducive to the operation and heat dissipation of the equipment in the base station cabinet.

[0089] In addition, it should be understood that although the present specification is described in terms of embodiments, not every embodiment contains only one independent technical solution. The description of the specification is only for the sake of clarity. Those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that those skilled in the art can understand.
