Under the condition, the generator can start to generate power to deliver electric energy to the load after receiving the start signal. However, in cold weather, the temperature of the generator is low and cannot reach the temperature at which power generation is started. As such, the generator needs to be heated so that it can reach a temperature at which it starts generating electricity.

At present, the starting and generating temperature of the generator is usually maintained in an electric auxiliary heating mode, so that the power consumption is high and the cost is high.

Because first pump sets up in the drain pipe of liquid reserve tank, and the inlet that is located one side of liquid layer switches on with the drain pipe that stretches into the liquid reserve tank. After the first pump is turned on, liquid in the reservoir is drawn into the liquid layer.

In addition, when the heat absorbing plate is irradiated by the sun, the heat absorbing plate can absorb solar energy to increase the temperature. Since the liquid layer covers the surface of the heat absorbing plate, the heat of the heat absorbing plate is transferred to the liquid in the liquid layer, so that the liquid in the liquid layer is heated. And because the liquid outlet positioned at the other side of the liquid layer is communicated with the liquid inlet pipe extending into the liquid storage tank, the liquid in the liquid layer is heated and flows into the liquid storage tank, and the circulation is carried out, so that the liquid in the liquid storage tank is heated.

Furthermore, when the second pump is turned on, the liquid in the liquid pipe circulates. And because the heat exchange tube is positioned in the liquid storage tank, the heat exchange tube can absorb the heat of the liquid in the liquid storage tank, and the liquid tube and the heat exchange tube form a circulating loop, so that the liquid in the liquid tube is heated. And because the liquid pipe is used for winding the generator, the liquid pipe can transfer the heat of the heated liquid to the generator, so that the generator is heated. In this way, the generator can be kept at a temperature at which power generation is started.

The specific meaning of the above terms in the present application can be understood in a specific case by those of ordinary skill in the art.

The following describes the technical solutions of the present application and how to solve the above technical problems with specific embodiments. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments. Embodiments of the present application will be described below with reference to the accompanying drawings.

As shown in fig. 1, the present application provides a generator heating apparatus comprising an absorber plate, a liquid layer 118, a tank 104, a heat exchange pipe 105, a first pump 107, a second pump 108, and a liquid pipe 124 for winding a generator 101. Wherein the absorber plate may be adapted to absorb solar heat, the liquid layer 118 may be a hollow sandwich, the hollow sandwich may be adapted to allow liquid to flow through, and the tank 104 may be adapted to store liquid. The heat exchange tube 105 is one of the elements of the heat exchanger, is used for heat exchange between two media, and has high heat conductivity and good isothermal property. A first pump 107 and a second pump 108 may be used to deliver the liquid. Note that, in order to enable the heat exchange pipe 105 to absorb the heat of the liquid in the liquid storage tank 104 more sufficiently, the heat exchange pipe 105 may have a spiral shape.

An inlet 112 at one side of the liquid layer 118 is in communication with an outlet 110 extending into the tank 104, and the first pump 107 is disposed at the outlet 110 of the tank 104. As such, when first pump 107 is activated, first pump 107 may draw liquid from tank 104 and into liquid layer 118 through outlet pipe 110 and inlet 112 on one side of liquid layer 118.

The liquid layer 118 covers the back side of the heat sink plate, so that the liquid flowing into the liquid layer 118 can effectively absorb the heat of the heat sink plate.

The liquid outlet 113 on the other side of the liquid layer 118 is communicated with the liquid inlet pipe 109 extending into the liquid storage box 104, and the liquid flowing into the liquid layer 118 absorbs the heat of the heat absorbing plate and then flows out from the liquid outlet 113 on the other side of the liquid layer 118. Since the outlet 113 on the other side of the liquid layer 118 is in communication with the inlet 109 extending into the tank 104, the liquid flowing out of the liquid layer 118 is returned to the tank 104, and the temperature of the liquid in the tank 104 is continuously increased by this circulation.

It will be appreciated that, based on the principles of thermal expansion and contraction, as the temperature of the liquid in the tank 104 increases, the volume of the liquid in the tank 104 also increases. Thus, the tank 104 may be provided with a space, and the top of the tank 104 may be provided with an air hole 106. When the volume of the liquid in the tank 104 increases, the liquid in the tank 104 may press the air in the headspace out through the air hole 106. This prevents the liquid tank 104 from being deformed by being pressed due to an increase in the volume of the liquid.

The heat exchange pipe 105 is located in the liquid storage tank 104, and as the temperature of the liquid in the liquid storage tank 104 increases, the temperature of the liquid in the heat exchange pipe 105 also increases. The liquid pipe 124 and the heat exchange pipe 105 constitute a circulation loop, and the second pump 108 is provided to the liquid pipe 124. The second pump 108, when activated, circulates the liquid in the circulation circuit of the liquid pipe 124 and the heat exchange pipe 105 so as to sufficiently absorb the heat of the liquid in the tank 104.

When the liquid pipe 124 is wound around the generator 101, heat of the liquid in the liquid pipe 124 may be transferred to the generator 101 in a non-operating state to heat the generator 101. In this manner, the generator 101 is allowed to keep reaching a temperature at which power generation is started. Further, the liquid pipe 124 may be wound around the generator 101 in a mesh manner, so that the contact area between the liquid pipe 124 and the generator 101 is large. In this manner, the heat of the liquid in the liquid pipe 124 can be more sufficiently transferred to the generator 101.

To sum up, the generator heating device that this application provided, when using, generator heating device can be placed in the open air and can be fully shone by sunshine the place to convert solar energy into heat energy and heat for the generator. Specifically, the liquid pipe 124 and the liquid tank 104 of the generator heating apparatus are filled with liquid. Since the first pump 107 is disposed in the outlet pipe 110 of the liquid tank 104, the liquid inlet 112 at one side of the liquid layer 118 is connected to the outlet pipe 110 extending into the liquid tank 104. After the first pump 107 is turned on, the liquid in the tank 104 is drawn into the liquid layer 118.

In addition, when the heat absorbing plate is irradiated by the sun, the heat absorbing plate can absorb solar energy to increase the temperature. Due to the liquid layer 118 covering the surface of the heat absorbing plate, the heat of the heat absorbing plate is transferred to the liquid in the liquid layer 118, so that the liquid in the liquid layer 118 is heated. And because the liquid outlet 113 on the other side of the liquid layer 118 is communicated with the liquid inlet pipe 109 extending into the liquid storage box 104, the liquid in the liquid layer 118 is heated and flows into the liquid storage box 104, and the circulation is performed, so that the liquid in the liquid storage box 104 is heated.

Also, when the second pump 108 is turned on, the liquid located in the liquid pipe 124 circulates. Also, since the heat exchange pipe 105 is located in the liquid storage tank 104, the heat exchange pipe 105 can absorb heat of the liquid in the liquid storage tank 104 and the liquid pipe 124 and the heat exchange pipe 105 form a circulation loop, so that the liquid located in the liquid pipe 124 is heated. Also, since the liquid pipe 124 is used to wind the generator 101, the liquid pipe 124 may transfer heat of the heated liquid to the generator 101, so that the generator 101 is heated. In this manner, the generator 101 that is not in the state can be kept up to the temperature at which the power generation is started. In the above process, the solar energy is used to keep the generator 101 at the temperature for starting the generation, so that the cost is low.

In a possible embodiment, the heat absorbing plate can be a photovoltaic plate 117, as shown in fig. 2, the generator heating device further comprises a storage battery 120 and a charging circuit 119, and the photovoltaic plate 117, the charging circuit 119 and the storage battery 120 are electrically connected in sequence. Photovoltaic panel 117 may convert solar energy to electrical energy, which is delivered to battery 120 for storage via charging circuit 119. It should be noted that the characteristics of the photovoltaic panel 117 are: the photovoltaic efficiency of the photovoltaic panel 117 is higher when the temperature of the photovoltaic panel 117 is lower, whereas the photovoltaic efficiency of the photovoltaic panel 117 is lower when the temperature of the photovoltaic panel 117 is higher. Since the liquid in the liquid layer 118 continuously absorbs the heat of the photovoltaic panel 117, the temperature of the photovoltaic panel 117 can be lowered, and thus, the photovoltaic efficiency of the photovoltaic panel 117 can be kept high. Further, the storage battery 120 can be made to store more electric energy.

As shown in fig. 1 and 3, the generator heating apparatus further includes a controller 103, a temperature sensor 123, a first switch 121, and a heater 122 provided to the generator 101. The controller 103 is electrically connected to the photovoltaic panel 117, the first switch 121, and the temperature sensor 123, respectively, and the battery 120, the first switch 121, and the heater 122 are electrically connected in this order. The photovoltaic panel 117 is used to convert solar energy into electrical energy to power the controller 103. The temperature sensor 123 is arranged on the surface of the generator 101, and the temperature sensor 123 is used for acquiring the temperature of the generator 101; the controller 103 is configured to control the first switch 121 to close when the temperature of the generator 101 is lower than a temperature threshold; the battery 120 is used to supply power to the heater 122 after the first switch 121 is closed. The element that determines whether the temperature of the generator 101 is lower than the temperature threshold may be the controller 103, or may be a comparator connected to the controller 103.

It will be appreciated that the liquid in the utilization tank 104 is not sufficient to heat the generator 101 to a temperature threshold, wherein the temperature threshold is greater than or equal to a temperature at which the generator 101 is able to initiate power generation. The heater 122 may also be powered by electrical energy within the battery 120. In this way, the heater 122 releases heat, the heat of the heater 122 can be transmitted to the generator 101, and the generator 101 can be maintained at a temperature at which power generation is started, and reliability is high.

In some embodiments, the generator heating device may include a second switch, the controller 103 being in electrical communication with the second switch, in turn, the first pump 107, the controller 103 being configured to periodically control the second switch to close. Illustratively, the controller 103 may be connected with a timer, and when the timing of each time of the timer reaches a preset time length, the controller 103 controls the second switch to be closed, so as to periodically control the second switch to be closed.

In this way, the controller 103 may periodically control the first pump 107 to pump the liquid in the tank 104 into the liquid layer 118, which may save power consumption. In the embodiments of the present application, the liquid may be water, oil, or the like, and is not limited herein.

As shown in fig. 4, the generator heating apparatus further includes: a voltage converter. The first switch 121 may be a single-pole double-throw switch, the heater 122 is electrically connected to a fixed end of the single-pole double-throw switch, and the controller 103 is further electrically connected to the battery 120. The controller 103 is further configured to control the free end of the spdt switch to be electrically connected to the voltage converter when the power of the battery 120 is lower than the power threshold. The threshold value of the electric quantity may be 2%, 5%, 8%, etc., and is not limited herein. The component for comparing whether the electric quantity of the storage battery 120 is lower than the electric quantity threshold may be the controller 103, or may be a comparator connected to the controller 103.

When the free end of the single pole double throw switch is switched into electrical connection with the voltage converter, the voltage converter may provide mains power to heater 122 so that heater 122 may remain releasing heat for generator 101. Thus, when the amount of electricity in the battery 120 is insufficient, the heat of the heater 122 can be transmitted to the generator 101, and the generator 101 can be maintained at a temperature at which power generation is started, which is highly reliable.

In a possible embodiment, the generator heating device comprises N heat absorbing plates and N liquid layers 118, each liquid layer 118 is located on the back of one heat absorbing plate, the liquid inlets 112 and the liquid outlets 113 of the N liquid layers 118 are connected in parallel, and N is an integer greater than or equal to 2. For example, N may be an integer of 2, 3, 4, etc. In this way, the N heat absorbing plates can convert more solar energy into electric energy to be stored in the battery 120, so that the solar energy can be more fully utilized.

It should be noted that when the heat absorbing plate is a photovoltaic plate 117, each photovoltaic plate 117 is electrically connected to the controller 103 through a wire. When N photovoltaic panels 117 are included, N wires are required to electrically connect to the controller 103. In this manner, in order to allow the wires to be regularly arranged and to protect the wires, a receiving case 116 may be provided on one side of any of the liquid layers 118 and one ends of the n wires close to the liquid layers 118 may be received in the receiving case 116.

Referring to fig. 1, the embodiment of the present application further provides a power generation system, and it should be noted that the power generation system provided by the embodiment of the present application has the same basic principle and technical effects as those of the embodiment described above, and for brief description, reference may be made to corresponding contents in the embodiment described above for a part not mentioned in the embodiment. The power generation system provided by the embodiment of the present application includes the generator 101 and the generator heating device provided in the above embodiment, and the liquid pipe 124 of the generator heating device is wound around the generator 101.

The generator 101 provided in the embodiment of the present application may be a diesel generator 101, or may be another type of generator 101, which is not limited herein. In some scenarios, the location of use of the generator 101 may be a data center, which needs to maintain data maintenance at all times, and thus, the load (e.g., servers) of the data center needs to be constantly powered. The generator 101 provided by the embodiment of the application can be used as a standby power supply of a load of a data center after a mains supply power failure.

In some embodiments, as also shown in fig. 1, the power generation system may further include a housing 102, and the generator 101 may be located within the housing 102. The housing 102 may be a rectangular parallelepiped housing, the housing 102 may protect the generator 101 from being damaged, and when the generator 101 is located in the housing 102, the generator 101 is conveniently transported and hoisted. The controller 103 may also be located within the housing 102, and the housing 102 may also protect the controller 103 from damage. In addition, the generator 101 and the controller 103 are both located in the same housing 102, which can reduce the occupied area of the power generation system and save the cost. When the generator 101 and the controller 103 are located within the same housing 102, the appearance of the power generation system may be as shown in fig. 5.

Additionally, as shown in FIG. 6, the reservoir 104 of the generator heating apparatus may be integrally formed with the housing 102 or removably attached thereto. Therefore, the power generation system can be more conveniently transported and hoisted, and the occupied area of the power generation system is smaller.

In some embodiments, as also shown in fig. 1, in order to further improve the power generation efficiency of the photovoltaic panel 117, a bracket 115 is disposed on the top of the housing 102, and the photovoltaic panel 117 is disposed on the bracket 115 and forms a predetermined angle with the housing 102. The preset angle may range from 30 degrees to 50 degrees (e.g., 30 degrees, 45 degrees, or 50 degrees). This may enable the photovoltaic panel 117 to more fully absorb solar energy.

In some alternative embodiments, one end of the photovoltaic panel 117 is pivotally connected to the top of the housing 102, and the other end of the photovoltaic panel 117 is suspended. The bracket 115 is a telescopic bracket, one end of the bracket 115 is connected with the top of the shell 102, and the other end of the bracket 115 is connected with the back of the photovoltaic panel 117. Thus, the user adjusts the photovoltaic panel 117 to form a preset angle with the housing 102 according to the sunlight irradiation angle, so that the photovoltaic panel 117 can absorb solar energy more sufficiently.

When the generator 101 is in the operating state, the first pump 107 and the second pump 108 may be controlled to stop operating. In this way, the generator loading device no longer heats the generator 101, saving energy.
