Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention belong to the protection scope of the present invention; the "and/or" keyword referred to in this embodiment represents sum or two cases, in other words, a and/or B mentioned in the embodiment of the present invention represents two cases of a and B, A or B, and describes three states where a and B exist, such as a and/or B, which represents: only A does not include B; only B does not include A; including A and B.
The solar cooking bench provided by the embodiment of the invention can be particularly applied to cooking operations such as cooking, cooking and water boiling by using solar energy, and has the characteristics of low cost and energy conservation.
Specifically, referring to fig. 1, the solar cooking bench includes at least: a thermally conductive body 100 and a heat collecting device 200.
As shown in fig. 2, the heat conducting body 100 can be placed on a table (e.g., a top 800), and the heat conducting body 100 is provided with a heat dissipating panel 110 for placing objects to be heated, such as pots, kettles, etc. The heat collecting device 200 is used for collecting heat energy, and a heat conducting channel is provided inside the heat collecting device 200.
As an implementation of the embodiment of the present invention, the heat conducting channel may be a channel for circulating a liquid, so that the liquid is injected into the heat conducting body 100 through the heat conducting channel to heat the object to be heated. Preferably, the thermal energy in the embodiment of the present invention may be solar energy. Of course, those skilled in the art will understand that solar energy is only one of the heat collected by the heat collecting device 200 in the embodiment of the present invention, and is not limited thereto. In other words, when the heat energy collected by the heat collecting device 200 is other energy, such as heat energy collected from some high temperature equipment in a high temperature working environment, or high temperature heat energy collected in a high temperature chamber for secondary utilization of the high temperature energy in the chamber, it is within the scope of the present invention.
Further, when the heat conducting channel is a channel for flowing liquid, liquid is filled into the heat collecting device 200 in advance, the liquid can be understood as a carrier of heat energy, so that the liquid is heated and warmed under the action of the heat energy (such as solar energy) collected by the heat collecting device 200, the heated liquid flows into the heat conducting body 100 through the heat conducting channel, and is subjected to heat transfer with the to-be-heated object placed on the heat radiating panel disc through the heat radiating panel disc 110, and finally cooking operations such as cooking, cooking and boiling water are realized.
Meanwhile, referring to fig. 3, the solar cooking bench according to the embodiment of the present invention further includes a storage tank 300 for storing liquid. The storage tank is connected to the heat conductive body 100 so that liquid can be circulated through the heat collecting device 200, the heat conductive body 100, and the storage tank 300. The liquid storage function of the storage tank 300 will be described in further detail below, and the heat conductive body 100 and the heat collecting device 200 will be described in further detail.
With respect to the thermally conductive body 100, as an example, with continued reference to fig. 2 and 3, the thermally conductive body 100 may include at least: a heat generating plate 120. The heat generating plate 120 includes at least: a first inlet port 121, a first outlet port 122, and a chamber 123. The first inlet 121 is connected to the heat collecting device 200, the first outlet 122 is connected to the storage tank 300, and the cavity 123 is located between the first inlet 121 and the first outlet 122. Thus, after the liquid in the heat collecting device 200 placed under the irradiation of sunlight is heated, the heated high-temperature liquid circularly flows through the cavity 123 of the heating plate 120 through the heat conducting channel, so that the heat energy carried by the high-temperature liquid can transfer heat to the object to be heated placed on the heat radiating panel plate, such as a pot, and finally, the food in the pot can be cooked. Preferably, the heating plate 120 may be fixed below the heat dissipation panel plate 110 to be in seamless engagement with the heat dissipation panel plate 110, or the heating plate 120 and the heat dissipation panel plate 110 may be integrally formed, that is, the upper surface of the heating plate 120 serves as the heat dissipation panel plate 110 for placing the object to be heated.
As another embodiment, please refer to fig. 4, the thermally conductive body 100 may include at least: an elbow 130. The elbow 130 includes at least: a second inlet port 131 and a second outlet port 132. The second liquid inlet 131 is connected to the heat collecting device 200, and the second liquid outlet 132 is connected to the storage tank 300. Thus, the liquid in the heat collecting device 200 placed under the irradiation of sunlight can be heated, and the heated high-temperature liquid circularly flows through the pipe of the bent pipe 130 through the heat conducting channel, so that the heat energy carried by the high-temperature liquid can transfer heat to the object to be heated, such as a pot, placed on the heat dissipation panel disc 110, and finally, the food in the pot can be cooked. Preferably, the bent tube 130 may be a spiral heat conducting thin tube wound below the heat dissipation panel disc 110, so that the entire heat conducting body 100 may have a "thin disc" structure, which is characterized by a simple structure.
Of course, it will be understood by those skilled in the art that the heating plate 120 and the bent pipe 130 are only two preferred embodiments of the heat conducting body 100 of the present invention, and when the heat conducting body 100 is formed by other heat conducting components, such as an oil tank capable of accommodating a volume of liquid of at least 1 liter or more, or a liquid storage chamber capable of circulating heated liquid, is suitable for the present invention. It should be noted that the heat conductive body 100 is used for heat transfer between the object to be heated and the heat collecting device 200, that is, heat energy collected by the heat collecting device 200 is transferred to the object to be heated to heat the object to be heated, in other words, the heat conductive body 100 capable of performing the above heat transfer function is within the protection scope of the present invention.
As an embodiment, please refer to fig. 1 continuously, the heat collecting device 200 may include: at least two heat collecting pipes 210 and a turning pipe 220. Wherein, all the heat collecting pipes 210 are arranged in parallel in array with equal spacing. Each heat collection tube 210 is filled with a liquid to be heated. The turning pipe 220 includes a third liquid outlet 221 and a plurality of third liquid inlets 222 with the same number as the heat collecting pipes 210. That is to say, the nozzle of one of the liquid collecting tubes 210 is correspondingly connected to one of the third liquid inlets 222, so that the heated liquid in the plurality of heat collecting tubes 210 sequentially flows into the turning tube 220 through the nozzle and the third liquid inlet 222 to be merged, and the merged heated liquid flows into the heating plate or the turning tube through the third liquid outlet 221.
It should be noted that, the turning pipe 220 is disposed in the heat collecting device 200, and the turning pipe 220 plays a role in transferring heated liquid in the plurality of heat collecting pipes 210, so that in the process of the liquid entering the heating plate 120 or the bent pipe 130, on one hand, different flow rates in different pipes are effectively buffered, on the other hand, due to different irradiation angles or different irradiation area parts in the plurality of heat collecting pipes 210, the heated temperatures of the liquid in different heat collecting pipes 210 may be more or less inconsistent, and before the liquid enters the heating plate 120 or the bent pipe 130, the liquid temperature coming out from all the heat collecting pipes 210 is unified through the turning pipe 220, so as to prepare for setting a temperature range or a temperature threshold in the heating plate 120, which will be described later. On the other hand, by providing the turning pipe 220, when the heat conducting body 100 is the bent pipe 130, since the second liquid inlet 131 of the bent pipe 130 is smaller, the pipe openings of the plurality of heat collecting pipes 210 cannot be connected with the second liquid inlet 131 of the bent pipe 130 at the same time, thereby preventing the heated liquid from flowing from the heat collecting pipes 210 to the heat conducting body 100. The turning pipe 220 is arranged to transfer the liquid flowing out of the heat collecting pipe 210, so that the technical problem that the liquid flows from the heat collecting pipe 210 to the heat conducting body 100 is solved.
Preferably, in the embodiment of the present invention, the turning pipe 220 is perpendicular to the plurality of heat collecting pipes 210, so that a plurality of third liquid inlets 222 are formed on the side wall of the turning pipe 220 in a manner that the plurality of heat collecting pipes 210 are arranged and distributed at equal intervals in an array manner, and finally, heated liquid in the plurality of heat collecting pipes 210 flows into the turning pipe 220 from the plurality of third liquid inlets 222 to be merged, so as to achieve the purposes of reasonable distribution of the installation structure between the heat collecting device 200 and the heat conducting body 100 and effective utilization of the operation space, which can be specifically shown in fig. 1.
As another embodiment, for the heat collecting device 200, a parabolic reflecting surface or a focusing mirror with a light condensing function may be further added to the heat collecting device 200 on the basis of the heat collecting tube 210, so that the light condensing function is realized by the parabolic reflecting surface or the focusing mirror, the purpose of efficiently collecting light by the heat collecting tube 210 is achieved, and finally, the cooking efficiency of the solar cooking bench provided by the embodiment of the present invention is improved.
It should be noted that, in order to prevent the heat energy from dissipating during the cooking operation, the heating efficiency is reduced. Preferably, the outer wall of the heating tray chamber 123, the outer wall of the elbow 130 and/or the outer wall of the heat collecting pipe 210 according to the embodiment of the present invention are provided with insulating layers for preventing heat energy from being lost.
It should be particularly noted that, in the embodiment of the present invention, in addition to the cooking operations of cooking, cooking and boiling water by using solar energy, and in order to avoid the technical defect that the present invention cannot be normally used in rainy weather (without sunlight irradiation), preferably, referring to fig. 5 to 6, an electric heating element 400 is further added in the embodiment of the present invention, the electric heating element 400 may be disposed on the heat dissipation panel disc 110, and the electric heating element 400 is externally connected with an electric heating device (such as a power supply), so that heat transfer occurs between the electric heating element 400 heated by the electric heating device and the heat dissipation panel disc 110, and the object to be heated is heated. The electric heating element may be a resistance wire, an electric heating sheet, an electric heating tube, or the like, and the embodiment of the present invention is not limited.
Similarly, the connection mode of the electric heating element 400 and the heat dissipation panel disc 110 is also various, and the electric heating element can be embedded in the heat dissipation panel disc in an embedding mode; or the electric heating element 400 and the disk 110 are arranged up and down in a stacking mode; or the electric heating element 400 is separated from the radiating panel disc 110, the electric heating element 400 is directly placed in the space where the liquid flows, such as the cavity 123 of the heating panel disc 110, the bent pipe 130, the heat collecting pipe 210 and the like, to heat the liquid, and then the purpose of heating the object to be heated is achieved by indirectly using the heat transfer between the liquid heated by the electric heating element and the radiating panel disc. However, it will be understood by those skilled in the art that whatever connection relationship or positional relationship between the electric heating element 400 and the heat dissipation panel plate 110 is, as long as heat dissipation of the heat dissipation panel plate 110 by the electric heating element 400 can be realized, is within the protection scope of the present invention. Finally, the object to be heated can be heated by collecting solar heat energy under the condition of illumination, the object to be heated can be heated by adopting electric energy under the condition of no illumination, or the object to be heated can be heated by adopting the two modes simultaneously in order to achieve the purpose of efficient operation (such as low illumination).
The reservoir 300 is used to temporarily store the high temperature liquid overflowing the heat generating tray chamber 123 due to thermal expansion. The storage tank 300 and the heating plate 120 may be connected by an oil pipe. The reservoir 300 is connected to the chamber 123 of the heat generating plate 120 through the first liquid outlet 122 or connected to the bent pipe 130 through the second liquid outlet 132. In the present embodiment, the regulation reservoir 300 has at least three functions:
first, when the high-temperature liquid in the heating tray chamber 123 overflows with the rise of temperature (due to the characteristic of expansion with heat and contraction with cold of the liquid), the overflowing liquid can enter the storage tank 300 for temporary storage, and when the temperature of the liquid drops, the liquid in the storage tank 300 can flow back to the heating tray chamber again.
Secondly, when solar heat energy needs to be stored, heated liquid can be used as a carrier, and the solar heat energy can be stored in the form of heat energy. Specifically, the liquid in the storage tank can be heated to a high temperature by solar energy. In the actual operation process, the volume of the storage tank 300 can be reasonably designed according to actual needs. For example, a well-insulated tank (which may be considered as a regulation reservoir) may be made, in which 5-10 times of high-temperature heat transfer oil is stored for releasing heat energy for heating the object to be heated when no sunlight is irradiated.
Thirdly, the volume of the liquid in the storage tank 300 is adjusted by adding a buoy (such as a hollow sphere) or adopting an external force extrusion method, so that the height of the liquid in the heating disc cavity 123 is adjusted, and the temperature which the high-temperature liquid can use can be changed artificially. For example, if the liquid level in the chamber 123 just touches the heat dissipation panel plate when the temperature of the high-temperature liquid reaches 200 ℃, the heat dissipation panel plate 110 can heat the pot placed thereon, so that the liquid temperature reaching 200 ℃ is the lowest use temperature of the solar cooking bench, and when the temperature reaches this temperature, the solar cooking bench can be used for cooking and frying rice. However, when the temperature of the liquid is lower than 200 ℃, the liquid volume is reduced due to expansion and contraction of the liquid, the liquid level cannot touch the heat dissipation panel plate, and the cooker placed on the liquid level cannot be heated well. However, in order to perform normal cooking (cooking and frying), the liquid level of the high-temperature liquid in the cavity of the heating plate can be adjusted in the storage tank 300, the cavity 123 of the heating plate or other places where the liquid can circulate by adding a hollow floating ball or extruding the storage tank by external force, so that the liquid can contact the radiating panel plate when the temperature of the liquid is lower than 200 ℃, and the purpose of manually adjusting the usable temperature of the solar cooker can be realized.
Of course, referring to fig. 7, the storage tank 300 according to the embodiment of the present invention may also be designed in a structure of a groove space. That is, a groove-shaped space 124 is formed around the top of the heating plate cavity 123, so that when high-temperature liquid overflows the solar heating plate cavity 123, the high-temperature liquid can enter the groove-shaped space 124, and when the temperature is reduced, the liquid can flow back to the heating plate cavity. Or, when the heat conducting body 100 includes an elbow, the storage tank 300 may be an oil tank, and the liquid flowing out from the elbow flows into the storage tank 300 at this time, so that the liquid in the storage tank 300 flows into the heat collecting device again by adding the oil pump, thereby recycling the liquid.
It should be noted that, in the embodiment of the present invention, the heat conducting body 100 may be located above the heat collecting device 200 or below the heat collecting device 200 according to actual operation requirements.
In particular, the method of manufacturing a semiconductor device,
when the heat conductive body 100 includes the heat generating plate 120, the heat conductive body 100 can be installed above the heat collecting device 200 for use, because the liquid heated by solar energy always flows to the uppermost layer due to its thermodynamic characteristics. Therefore, the liquid in the heat generating pan chamber 123 (the liquid above the heat collecting device 200) is the highest temperature liquid in the whole liquid circulation passage. And finally, effective heating of the object to be heated placed on the heat radiation panel disk 110 is achieved.
When the heat conductive body 100 includes the bent pipe 130, the heat conductive body 100 may be installed below the heat collecting device 200 for use, for example, the heat collecting device 200 is installed on the roof, and the solar cooker is placed in a kitchen below the building. Since the position of the solar cooking bench is lower than that of the heat collecting device 200, an oil pump can be additionally arranged in the heat conducting body 100 to promote the circulation of high-temperature liquid in the system. Finally, the object to be heated placed on the radiating panel disc is effectively heated.
The working principle of the solar cooking bench provided by the embodiment of the invention is described in detail below to further support the technical problem to be solved by the invention.
For ease of understanding, the concept of the relative temperature of a high temperature liquid is defined as follows:
minimum use temperature: when the temperature of the heated liquid reaches the lowest use temperature, the heat dissipation temperature of the heat dissipation panel plate can be understood to basically meet the normal temperature of cooking and frying, and the lowest use temperature is assumed to be 200 ℃;
safe use temperature: when the temperature of the heated liquid reaches the safe use temperature, the heat dissipation temperature of the heat dissipation panel plate can be understood to not only meet the normal cooking and cooking temperature, but also be regarded as stronger firepower and be within the safe temperature range, and the safe use temperature is assumed to be 279 ℃;
limiting temperature: when the temperature of the heated liquid reaches the limit temperature, it can be understood that the heat radiation temperature of the heat radiation panel disc has a safety hazard, such as combustion, and the limit temperature is assumed to be 280 ℃.
The working principle of the solar cooking bench provided by the embodiment of the invention can be as follows:
first, the heat collecting device 200 is installed at a position where solar light can be irradiated, so that the heat collecting device can receive the solar light, and meanwhile, the pipe opening of the heat collecting pipe 210 is in butt-joint communication with the third liquid inlet 222 of the turning pipe 220, so that liquid can freely flow between the heat collecting device 200 and the heat conducting body 100 without leakage, thereby forming a liquid circulation channel.
Then, liquid (such as oil) for conducting heat energy is filled into the liquid circulation channel; the liquid filling amount can be set according to the following method: when the liquid temperature is lower than the lowest use temperature, the liquid level of the liquid can not touch the heat dissipation panel disc; when the temperature reaches the lowest use temperature, the liquid level height of the liquid can contact the heat dissipation panel disc; when the temperature reaches the limit temperature, the liquid overflows the solar heating plate and enters the regulating and storing tank.
Then, under the irradiation of sunlight, the temperature of the liquid in the heat collecting device and the liquid in the whole circulating circulation channel rises rapidly, after the temperature of the liquid reaches the lowest use temperature, the liquid level of the liquid can touch the heat dissipation panel disc, so the temperature of the heat dissipation panel disc also reaches a high-temperature state under the action of heat transfer to generate heat and scald, and at the moment, only a pot or a container filled with food is placed on the heat dissipation panel disc of the solar heating disc, and the food in the pot or the container can be cooked.
Then, as the temperature of the high temperature liquid in the heat generating tray chamber 123 is higher, the thermal power thereof for cooking or frying rice is larger. For safety, however, embodiments of the present invention may set a safe temperature range, such as the safe use temperature described above, according to the nature or ignition point of the injected liquid. When the temperature of the liquid exceeds the limit temperature, the embodiment of the invention can stop the heat collecting device from receiving the illumination or ensure that the liquid in the liquid circulation channel is cooled by heat dissipation so as to ensure the safety.
Or, when it is not ensured that the high-temperature liquid naturally flows in the whole liquid circulation channel by means of buoyancy (the highest temperature flows to the highest position due to light weight, and the low temperature sinks due to relatively heavy weight), the embodiment of the invention assists the circulation flow of the high-temperature liquid by additionally arranging a power pump (such as a water pump or an oil pump) so as to conduct heat energy. This kind of condition can be applicable to when the heat conduction body is the return bend, install heat collection device in the position or the roof that are higher than the heat conduction body, implement cooking operation.
It should be particularly noted that the solar cooking bench provided by the embodiment of the present invention can use solar energy or electric energy by adding the electric heating element 400 in the heat conducting body 100. In daily life, weather is changeable, and the weather is always sunny when it is cloudy or strong and weak when it is lighted, especially rainy weather. At this time, in order to ensure that the solar cooking bench can still be used normally, in the embodiment of the present invention, the electric heating element 400 is additionally arranged in the heat conducting body 100, the electric heating element 400 is connected to an electric heating device (such as a power supply), the electric heating device drives the electric heating element 400 to generate heat, the electric heating element 400 causes the temperature of the heat dissipation panel disc to be gradually increased under the heat transfer effect, and then the object to be heated placed on the heat dissipation panel disc 110 is heated. Finally, the cooking operation can be carried out by using solar energy in sunny days or cloudy days, and the cooking operation is carried out in an electric energy mode by switching to the electric heating element. Similarly, in the embodiment of the present invention, by providing the storage tank 300, when the illumination is good, the storage tank 300 or the high temperature liquid storing a certain amount of heat can be used for releasing heat energy at night or in rainy days to cook and fry. Preferably, a valve may be disposed in an oil pipe connected between the storage tank 300 and the heat conductive body 100, and the circulation of the high-temperature liquid between the storage tank and the heat conductive body is realized by controlling the opening and closing of the valve.
In addition, in order to further enhance the recycling of the solar energy, the embodiment of the invention further provides a water tank heat receiver 600 and a tray cover 500, as shown in fig. 8, the tray cover 500 is adapted to the heat dissipation panel tray 110 of the heat conduction body 100, and the two are detachably connected (e.g., clamped) to facilitate the detachment of the two, and of course, the detachable connection here may also be an open-close type movable connection manner, so that the tray cover 500 can be turned over relative to the heat dissipation panel tray 110 of the heat conduction body 100, thereby implementing the opening and closing functions of the tray cover 500. Wherein, the water tank heat receiver 600 includes: a cavity chamber 620 and a heat receiving surface 610, and the water tank heat receiver 600 is disposed on the tray cover 500 through the heat receiving surface 610, so that the heat dissipation panel tray 110 of the heat conductive body 100 according to the embodiment of the present invention can perform heat transfer between the tray cover 500 and the heat receiving surface 610 of the water tank heat receiver 600.
In detail, the tank heat receiver 600 is provided with a plurality of interfaces, and is connected with the corresponding interfaces of the plurality of tanks 700 through flexible pipes (hoses) or other multi-section water pipes, so that the tank heat receiver 600 is communicated with the plurality of tanks 700. Thus, when the heat receiving surface 610 of the water tank heat receiver 600 is in heat transfer with the heat dissipating panel plate 110 of the heat conducting body 100 through the plate cover 500, the water temperature of the water to be heated in the cavity chamber 620 and the plurality of water tanks 700 also gradually rises, because the water tank heat receiver 600 is communicated with the water tanks 700 through the interfaces, the water with high temperature after being heated automatically enters the plurality of water tanks 700 through the interfaces under the action of buoyancy, the water with relatively low temperature automatically sinks into the cavity chamber 620 of the water tank heat receiver 600 for heating, and the circulation is performed, so that the water temperature in the water tanks 700 can finally rise rapidly. Similarly, in order to promote the circulation of water, a water pump can be added to assist the circulation of water, and the principle of promoting the circulation of water by the water pump is known in the art and is not described in detail herein.
Preferably, the tray cover 500 may further include a heat insulating layer to prevent heat from being dissipated.
Finally, referring to fig. 9, the heat conductive body 100 may be further disposed in a cylindrical accommodation chamber 900, so that when an object to be heated is disposed in the cylindrical accommodation chamber 900, the object to be heated is heated by the heat conductive body 100. Still further, the method may further include: and the pot cover 1000 is matched with the top structure of the cylindrical accommodating chamber 900 and is detachably connected with the top structure, so that the pot cover 1000 can be used for preserving heat of the object to be heated in the cylindrical accommodating chamber 900.
