Description

Technical Field

[0001] The utility model relates to the field of heat dissipation of electronic components, and in particular to a temperature control device and an edge server. Background Art

[0002] The electronic components on a circuit board need to operate at the right temperature to function properly. If the temperature is too high, they will burn out, and if the temperature is too low, they will not start properly. To this end, the circuit board is generally equipped with a cooling fan and heater. The cooling fan and heater will turn on and off according to the detected temperature of the electronic components to ensure that the electronic components are kept at the appropriate temperature.

[0003] For existing circuit boards, the adjustment of cooling fans and heaters is mainly controlled by programs, which requires the main control chip to perform corresponding logical judgments in real time, which increases the energy consumption of the circuit board. Utility Model Content

[0004] Based on this, it is necessary to provide a temperature control device and an edge server to address the problem of high energy consumption of circuit boards.

[0008] The temperature control device has at least a heating state and a heat dissipation state;

[0009] When the temperature control device is in a heating state, the first electrical connector and the third electrical connector are electrically connected to enable the heater to operate, and the second electrical connector and the fourth electrical connector are spaced apart to disable the radiator;

[0010] When the temperature control device is in a heat dissipation state, the first electrical connector and the third electrical connector are spaced apart to stop the heater from working, and the second electrical connector and the fourth electrical connector are electrically connected to enable the radiator to work.

[0011] The temperature control device also has a normal temperature state, when the temperature control device is in the normal temperature state, the first electric connector and the third electric connector are arranged at intervals, so that the heater stops working, and the second electric connector and the fourth electric connector are arranged at intervals, so that the radiator stops working.

[0012] The temperature-controlled component is arranged on one side of the first circuit board away from the second circuit board, and the radiator is a fan and is located on the side of the first circuit board away from the second circuit board.

[0013] The first circuit board is provided with a temperature-controlled component, and the temperature-controlled component and the heater are oppositely arranged and located on two sides of the first circuit board.

[0014] The temperature-controlled component is provided with a heat dissipation fin.

[0015] The elastic member is in a stretched state.

[0016] The second electric connector includes a first conductive plate and a first conductive rod, one end of the first conductive plate is fixed on the first conductive rod, and the other end of the first conductive rod is arranged on the side of the first circuit board facing the second circuit board, so that the first conductive plate and the first circuit board are opposite and arranged at intervals.

[0017] The fourth electric connector includes a second conductive plate and a second conductive rod, one end of the second conductive plate is fixed on the second conductive rod, and the other end of the second conductive rod is arranged on the side of the second circuit board facing the first circuit board, so that the second conductive plate and the second circuit board are opposite and arranged at intervals.

[0018] The first conductive plate and the second conductive plate are oppositely arranged, and the second conductive plate is located between the first conductive plate and the first circuit board.

[0020] The first electric connector is located on the side of the first circuit board facing the second circuit board, and the third electric connector is located on the side of the second circuit board facing the first circuit board.

[0021] The first electric connector and the third electric connector are both conductors, when the temperature control device is in the heating state, the first electric connector and the third electric connector are in surface contact.

[0022] An edge server includes the temperature control device.

[0023] The beneficial effects of the utility model are:

[0024] When the temperature of the temperature-controlled component is low, heat conduction causes the thermal expansion element to contract. This, in conjunction with the elastic member, reduces the distance between the first and second circuit boards. This allows electrical connection between the first and third electrical connectors, while disconnecting the second and fourth electrical connectors. Consequently, the heater automatically activates and the radiator automatically deactivates, allowing the temperature of the temperature-controlled component to quickly rise and return to its normal operating temperature.

[0025] When the temperature of the temperature-controlled component reaches a high level, heat conduction causes the thermal expansion element to expand. This, in conjunction with the elastic member, increases the distance between the first and second circuit boards. This disconnects the first and third electrical connectors, while simultaneously connecting the second and fourth electrical connectors. Consequently, the heater automatically stops and the heat sink automatically starts, rapidly cooling the temperature of the temperature-controlled component back to its normal operating temperature.

[0026] The above-mentioned control of the working status of the heater and the radiator does not involve program judgment, but is automatically achieved through the heat conduction of the temperature-controlled components to the thermal expansion elements. Therefore, there is no need to monitor the temperature of the temperature-controlled components in real time. Compared with the existing technology, the energy consumption of the temperature control device of the utility model is lower. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] Example:

[0039] See also Figure 1-Figure 3 This embodiment provides an edge server, including a temperature control device. The temperature control device specifically includes a first circuit board 1, a second circuit board 2, an elastic member 3, a thermal expansion element 4, a heater 5 and a radiator 6.

[0040] The first circuit board 1 and the second circuit board 2 are arranged opposite each other. In this embodiment, the elastic member 3 is a spring and is located between the first circuit board 1 and the second circuit board 2, with its two ends respectively disposed on the first circuit board 1 and the second circuit board 2. The thermal expansion element 4 is also located between the first circuit board 1 and the second circuit board 2, with its two ends respectively disposed on the first circuit board 1 and the second circuit board 2.

[0041] When the temperature of the first circuit board 1 and / or the second circuit board 2 is high, the heat on the first circuit board 1 and / or the second circuit board 2 is transferred to the thermal expansion element 4, causing the thermal expansion element 4 to expand, thereby increasing the distance between the first circuit board 1 and the second circuit board 2. When the temperature of the first circuit board 1 and / or the second circuit board 2 is low, the thermal expansion element 4 contracts, and the distance between the first circuit board 1 and the second circuit board 2 can be reduced.

[0042] The thermal expansion element 4 will also deform the elastic member 3 during the expansion and contraction process.

[0043] In some embodiments, the first circuit board 1 can compress the elastic member 3 by gravity, causing the elastic member 3 to remain in a compressed state. The elastic member 3 and the thermal expansion element 4 cooperate to support the first circuit board 1. In these embodiments, the thermal expansion element 4 can lift the first circuit board 1 through thermal expansion, thereby allowing the elastic member 3 to partially recover and reducing the amount of compression of the elastic member 3. The thermal expansion element 4 can also contract, causing the first circuit board 1 to further compress the elastic member 3.

[0044] In this embodiment, the elastic member 3 is always in a stretched state, so its two ends need to be fixed to the first circuit board 1 and the second circuit board 2, respectively. In this embodiment, when the thermal expansion element 4 expands, the elastic member 3 further increases its stretched deformation. When the thermal expansion element 4 contracts, the elastic member 3 is allowed to partially recover and reduce its stretched deformation, thereby allowing the first circuit board 1 and the second circuit board 2 to approach each other, and the thermal expansion element 4 to be consistently clamped between the first circuit board 1 and the second circuit board 2. Therefore, in this embodiment, the coordination between the elastic member 3 and the thermal expansion element 4 does not restrict the installation orientation of the first circuit board 1 and the second circuit board 2.

[0045] In this embodiment, the temperature-controlled component 7 that needs to be temperature-controlled is disposed on the first circuit board 1. The temperature-controlled component 7 operates on the first circuit board 1, so that the temperature-controlled component 7 can directly conduct heat to the first circuit board 1. On this basis, the heater 5 and the radiator 6 are both installed on the first circuit board 1. The heater 5 can increase the temperature of the temperature-controlled component 7 by heating the first circuit board 1. If the radiator 6 is a fan, it can directly blow air onto the temperature-controlled component 7 to lower the temperature of the temperature-controlled component 7. If the radiator 6 is a cooling plate, the radiator 6 can lower the temperature of the temperature-controlled component 7 by lowering the temperature of the first circuit board 1.

[0046] A first electrical connector 11 and a second electrical connector 12 are spaced apart on the first circuit board 1, and a third electrical connector 21 and a fourth electrical connector 22 are spaced apart on the second circuit board 2. In this embodiment, the first electrical connector 11 and the second electrical connector 12 are located on the side of the first circuit board 1 facing the second circuit board 2, and the third electrical connector 21 and the fourth electrical connector 22 are located on the side of the second circuit board 2 facing the first circuit board 1.

[0047] As one optional structure, in this embodiment, the first electrical connector 11 and the third electrical connector 21 are both conductors, and the second electrical connector 12 and the fourth electrical connector 22 are both L-shaped.

[0048] Specifically, the second electrical connector 12 includes a first conductive plate 121 and a first conductive rod 122. The first conductive plate 121 and the first conductive rod 122 are both conductors. The first conductive plate 121 is fixed at one end of the first conductive rod 122, and the other end of the first conductive rod 122 is arranged on the side of the first circuit board 1 facing the second circuit board 2, so that the first conductive plate 121 and the first circuit board 1 can be arranged relative to each other and spaced apart.

[0049] The fourth electrical connector 22 includes a second conductive plate 221 and a second conductive rod 222. The second conductive plate 221 and the second conductive rod 222 are both conductors. The second conductive plate 221 is fixed at one end of the second conductive rod 222, and the other end of the second conductive rod 222 is arranged on the side of the second circuit board 2 facing the first circuit board 1, so that the second conductive plate 221 and the second circuit board 2 can be arranged relative to each other and spaced apart.

[0050] The first conductive plate 121 and the second conductive plate 221 are arranged opposite to each other, and the second conductive plate 221 is located between the first conductive plate 121 and the first circuit board 1 .

[0051] Based on the above structure, when the first circuit board 1 and the second circuit board 2 are brought closer to each other, the first electrical connector 11 and the second electrical connector 12 are brought closer to each other, while the first conductive plate 121 and the second conductive plate 221 are moved away from each other. When the first circuit board 1 and the second circuit board 2 are moved away from each other, the first electrical connector 11 and the second electrical connector 12 are moved away from each other, while the first conductive plate 121 and the second conductive plate 221 are brought closer to each other.

[0052] Therefore, the temperature control device of this embodiment has a heating state, a normal temperature state and a heat dissipation state.

[0053] See also Figure 1 When the temperature of the temperature-controlled component 7 is low, the thermal expansion element 4 can be contracted, the distance between the first circuit board 1 and the second circuit board 2 is small, the first electrical connector 11 and the third electrical connector 21 can be electrically connected through contact, and the heater 5 can automatically start heating to increase the temperature of the temperature-controlled component 7. At this time, the temperature control device is in the heating state.

[0054] As a preference, the temperature-controlled component 7 and the heater 5 are arranged opposite to each other and are respectively located on two sides of the first circuit board 1 , so as to shorten the heat conduction path between the temperature-controlled component 7 and the heater 5 .

[0055] In addition, when the temperature control device is in the heating state, the first electrical connector 11 and the third electrical connector 21 are in surface contact, so as to improve the electrical connection stability between the first electrical connector 11 and the third electrical connector 21 .

[0056] When the temperature control device is in the heating state, the first conductive plate 121 and the second conductive plate 221 are spaced apart from each other, and the second electrical connector 12 and the fourth electrical connector 22 remain spaced apart and disconnected, thereby causing the radiator 6 to stop working to allow the temperature-controlled component 7 to increase in temperature more quickly.

[0057] See also Figure 2 When the temperature control device is at room temperature, the spacing between the first circuit board 1 and the second circuit board 2 is moderate, and the first electrical connector 11 and the third electrical connector 21 are spaced closely apart, thereby deactivating the heater 5 and preventing it from heating the temperature-controlled component 7. At the same time, the first conductive plate 121 and the second conductive plate 221 remain spaced closely apart, allowing the second electrical connector 12 and the fourth electrical connector 22 to remain disconnected and deactivate the heat sink 6. At this point, neither the heater 5 nor the temperature-controlled component 7 is required to operate, allowing the temperature control device to maintain a low power consumption level.

[0058] When the temperature control device is at room temperature, the temperature-controlled component 7 can operate normally, and thus the temperature-controlled component 7 can also generate heat. Based on this, heat dissipation fins 71 can be provided on the temperature-controlled component 7 to enhance the natural heat dissipation capacity of the temperature-controlled component 7, so that the temperature-controlled component 7 can reach thermal equilibrium through the heat dissipation fins 71 as much as possible, so that the temperature control device can be kept at room temperature for as long as possible, thereby reducing the energy consumption of the temperature control device.

[0059] See also Figure 3 When the temperature of the temperature-controlled component 7 is high, the temperature control device is in a heat dissipation state. At this time, the distance between the first circuit board 1 and the second circuit board 2 is large, and the first electrical connector 11 and the third electrical connector 21 are separated and disconnected, thereby stopping the operation of the heater 5. Simultaneously, the first conductive plate 121 and the second conductive plate 221 come into contact, electrically connecting the second electrical connector 12 and the fourth electrical connector 22. The heat sink 6 automatically begins to operate, cooling the temperature-controlled component 7.

[0060] Preferably, when the temperature control device is in the heat dissipation state, the second conductive plate 221 and the first conductive plate 121 are in contact with each other to improve the electrical connection stability between the second electrical connector 12 and the fourth electrical connector 22 .

[0061] In this embodiment, the radiator 6 is a fan, and the radiator 6 and the temperature-controlled component 7 are both located on the side of the first circuit board 1 facing away from the second circuit board 2. On the one hand, this allows the temperature-controlled component 7 to have more sufficient space to dissipate heat. On the other hand, the radiator 6 can directly blow the temperature-controlled component 7 and the cooling fins 71 to maximize the heat dissipation effect on the temperature-controlled component 7.

[0062] In summary, in this embodiment, when the actual temperature of the temperature-controlled component 7 deviates from the normal operating temperature, the expansion state of the thermal expansion element 4 can be changed through heat exchange with the first circuit board 1. The thermal expansion element 4 then cooperates with the elastic member 3 to automatically adjust the distance between the first circuit board 1 and the second circuit board 2, thereby changing the operating state of the heater 5 and the heat sink 6. Furthermore, the changed operating state of the heater 5 and the heat sink 6 can match the current actual temperature of the temperature-controlled component 7, allowing the actual temperature of the temperature-controlled component 7 to return to the normal operating temperature as quickly as possible.

[0063] In some other embodiments, the temperature-controlled component 7, the heater 5 and the radiator 6 may also be arranged on the second circuit board 2. The working principles thereof are similar to those of this embodiment and will not be further described.

[0064] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0065] The above-described embodiments merely represent several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
