Description

Technical Field

[0001] The invention belongs to the technical field of efficient utilization of solar energy, and in particular relates to a heat pipe type solar vacuum heat collection evaporator. Background Art

[0002] The vacuum tube is a high-efficiency heat transfer element. Due to its high efficiency and good safety performance, it is widely used in heat pipe solar vacuum collector evaporators to convert solar energy into heat energy for absorption and use.

[0003] The heat pipes of the commonly used heat pipe type solar vacuum collector evaporator are often unable to make good use of heat energy due to their limited light-facing surface area. To solve the above problems, the existing design provides a solution of adding a fixed arc cover to reflect the sunlight that originally passed through the gap between two adjacent heat pipes and could not be used, so that it can be absorbed and utilized more by the heat pipe. The above solution has improved the utilization rate of sunlight per unit area to a certain extent, but because the position of the sun is relatively variable, the fixed arc cover in the design cannot effectively utilize the sunlight in the morning rising state and the sunlight in the afternoon setting state, and the effect of improving the efficiency of the heat pipe type solar vacuum collector evaporator equipment is very limited; in addition, because the vacuum tube of the vacuum collector is made of glass, it is often damaged by falling foreign objects such as flying stones and hail in some areas.

[0057] like Figures 1 to 7 As shown, a heat pipe solar vacuum heat collection evaporator described in the present application comprises a bracket 1 and a columnar shell 2 connected to one end of the bracket 1 away from the ground, the end of the bracket 1 away from the shell 2 is supported on the ground, and the bracket 1 supports the shell 2 at a position away from the ground;

[0058] The heat pipe solar vacuum heat collection evaporator further comprises:

[0059] A heat exchange main pipe 21, wherein the heat exchange main pipe 21 is disposed in the shell 2;

[0060] A heat pipe 22, wherein the heat pipe 22 is arranged in parallel with the inclined section of the bracket 1 (the inclination angle of the heat pipe 22 is the same as the inclination angle of the inclined section of the bracket 1), the heat pipe 22 penetrates the shell 2 and is connected with the heat exchange main pipe 21, and the axis of the heat pipe 22 is perpendicular to the axis of the heat exchange main pipe 21 (here, it is not limited whether the two axes intersect or not); a plurality of heat pipes 22 are provided, the plurality of heat pipes 22 are spaced from each other, and the axes of the plurality of heat pipes 22 are parallel to each other, and the intersection line of the connection between the plurality of heat pipes 22 and the heat exchange main pipe 21 is parallel to the axis of the heat exchange main pipe 21; the diameter of the heat pipe 22 is smaller than the diameter of the heat exchange main pipe 21;

[0061] An arc-shaped cover 3, wherein the arc-shaped cover 3 is arranged on the outer peripheral side of the heat pipe 22, the axis of the arc-shaped cover 3 is parallel to the axis of the heat pipe 22, and a reflective film 31 is arranged on one side of the arc-shaped cover 3 close to the heat pipe 22;

[0062] The first driving component 4 is disposed on one side of the bracket 1 , and is configured to drive the arc cover 3 to rotate along the circumference of the heat pipe 22 with its own axis as the axis.

[0063] In the present invention, by setting the arc cover 3 driven by the first driving component 4, the sunlight that was originally unusable is reflected, and the heat energy of the light that was originally unreceivable is applied to the heat pipe 22, so that the original back-to-sun side of the heat pipe can be utilized to absorb more heat, which has a positive significance for improving the heat collection efficiency of the equipment.

[0064] In a specific implementation of this embodiment, the shell 2 is a shell structure having a cylindrical hollow cavity, and the outer diameter of the heat exchange main pipe 21 is smaller than the inner diameter of the hollow cavity in the shell 2 .

[0065] In another specific implementation of this embodiment, the shell 2 is a square columnar hollow shell structure, the hollow cavity inside the shell 2 is cylindrical, and the diameter of the cylindrical hollow cavity is greater than or equal to the outer diameter of the heat exchange main pipe 21.

[0066] In a specific implementation of this embodiment, an annular gasket (not shown in the figure) is provided on the inner wall of the hollow cavity in the housing 2;

[0067] When the heat exchange main pipe 21 extends into the shell 2 and cooperates therewith, the annular gasket is compressed and deformed.

[0068] In the present invention, through the above arrangement, the heat exchange main pipe 21 can extend into and penetrate the shell 2 to form an integrated structure of the two without relative shaking; the arrangement of the shell 2 also provides effective protection for the heat exchange main pipe 21 and the connection between the heat exchange main pipe 21 and the heat pipe 22.

[0069] In a specific implementation of this embodiment, the diameter of the heat pipe 22 is smaller than the diameter of the main heat exchange pipe 21 .

[0070] In the present invention, by setting the heat pipe 22 with a smaller diameter, it is possible to ensure smooth flow between the water with a higher temperature rising in the heat pipe 22 and the water with a lower temperature in the heat exchange main pipe 21 .

[0071] Please refer to the attached Figure 2 In a specific implementation of this embodiment, the bracket 1 further includes a vertical section, a connecting section and a horizontal section (not shown in the figure), and the inclined section, the vertical section, the connecting section and the horizontal section each include two relatively arranged roots;

[0072] One end of the inclined section away from the ground is connected to one end of the vertical section away from the ground, and one end of the inclined section close to the ground is connected to the horizontal section and the connecting section, and the horizontal section and the connecting section are vertically arranged;

[0073] One end of the vertical section close to the ground is connected to the horizontal section and the connecting section, and the horizontal section and the connecting section are vertically arranged;

[0074] From a perspective along the axis direction parallel to the horizontal segment, the inclined segment, the connecting segment and the vertical segment are connected in pairs to form a triangular structure;

[0075] In a viewing angle along the axis direction parallel to the connecting section, the inclined section and the vertical section partially overlap;

[0076] The housing 2 is disposed at one end of the inclined section and the vertical section away from the ground.

[0077] In a specific implementation of the present embodiment, since adjacent heat pipes 22 are spaced a certain distance apart and the original back-to-sun side of the heat pipe 22 cannot receive sunlight, the reflective film 31 reflects the sunlight irradiated on the arc cover 3 to the original back-to-sun side (the side not directly facing the sun) of the heat pipe 22, so that the originally unusable sunlight can provide more heat energy for the heat pipe 22, thereby improving the heat collection effect of the (heat pipe type solar vacuum thermal collector evaporator) equipment.

[0078] In a specific implementation of this embodiment, the reflective film 31 includes a reflective layer and an adhesive layer (not shown in the figure), and the reflective layer is adhered and mounted on the inner side surface of the arc cover 3 (the side of the arc cover 3 close to the heat pipe 22) through the adhesive layer;

[0079] The reflective layer may be a metal structural layer (such as aluminum), or a structural layer made of other materials with high reflectivity.

[0080] Please refer to the attached Figure 5 To Attachment Figure 7 In a specific implementation of this embodiment, the central angle of the arc cover 3 is 120°-180°;

[0081] Preferably, in a specific implementation of this embodiment, the central angle corresponding to the arc cover 3 is 130°-160°;

[0082] More preferably, in a specific implementation of this embodiment, the central angle corresponding to the arc cover 3 is 140°.

[0083] In a specific implementation of this embodiment, the axis of the arc cover 3 coincides with the axis of the heat pipe 22 .

[0084] Please refer to the attached Figure 5 To Attachment Figure 7 In a specific implementation of this embodiment, the multiple arc covers 3 arranged on the multiple heat pipes 22 do not contact each other, that is, the spacing distance between two adjacent heat pipes 22 is greater than the diameter (centroid distance) of the arc cover 3.

[0085] In a specific implementation of this embodiment, the heat pipe solar vacuum collector evaporator further includes:

[0086] The control module 6 is configured to collect data information and perform corresponding control operations according to the collected data information.

[0087] Please refer to the attached Figure 4 To Attachment Figure 7 Specifically, the control module 6 includes a data processing unit 61, a light chasing unit 62 and a hail detection unit 63. The data processing unit 61 is configured to perform corresponding control operations (issue corresponding control instructions to control the rotation of the arc cover 3) according to the collected data information, the light chasing unit 62 is configured to detect sunlight irradiation angle information (a type of data information), and the hail detection unit 63 is configured to detect whether there is hail or other falling object information in the surrounding environment (a type of data information);

[0088] The light-chasing unit 62 is electrically connected to the data processing unit 61; the light-chasing unit 62 is used to detect the sunlight irradiation angle, and is used to control the arc cover 3 to maintain the best irradiation angle with the sunlight (the sunlight incident angle and the centroid line of the heat pipe 22 and the arc cover 3 are on a straight line). The unit module / component (light-chasing unit 62) with the light-chasing function is a mature and common-sense technology in the field, and will not be described in detail here;

[0089] The hail detection unit 63 is electrically connected to the data processing unit 61; the hail detection unit 63 is used to detect whether hail (or other falling objects) is falling in the surrounding environment. When hail is detected in the surrounding environment, the arc cover 3 is controlled to rotate to prevent hail or other foreign objects from falling on the vacuum tube 23 (heat pipe 22) of the equipment. The unit module / component (hail detection unit 63) for detecting the surrounding environment state is a mature and common-sense technology in the field and will not be elaborated here.

[0090] In a specific implementation of this embodiment, the hail detection unit 63 is an optical sensor (optical recognition method), or the hail detection unit 63 is a weather radar (sound wave recognition method).

[0091] In a specific implementation of this embodiment, the light chasing unit 62 and / or the hail detection unit 63 are turned on and off with a predetermined time t as a cycle to perform detection.

[0092] In a specific implementation of the present embodiment, the predetermined time t corresponding to the light chasing unit 62 and / or the hail detection unit 63 can be determined as needed; for example, because the weather changes (affecting the light) in winter are more frequent and faster than in summer, the time t in summer (such as 10 minutes) is greater than the time t in winter (such as 5 minutes); for another example, the time t in the morning (such as 5 minutes) is greater than the time t in the afternoon (such as 2 minutes).

[0093] Please refer to the attached Figure 5 To Attachment Figure 6 For the convenience and clarity of explanation, the side of the heat pipe 22 facing the sun (the side of the inclined section away from the vertical section) is called the sun-facing side, and the side of the heat pipe 22 facing away from the sun (the side of the inclined section facing the vertical section) is called the back-sun side; it can be understood that the device is fixed and the sun is relatively moving. According to the rotation of the sun's position, for a single heat pipe 22, the corresponding positions of the so-called sun-facing side and back-sun side are variable. The light-chasing unit 62 drives the arc cover 3 to rotate on the back-sun side (to ensure the incident angle of the sun, please refer to the attached Figure 5 and attached Figure 7When hail falls, the hail detection unit 63 drives the arc cover 3 to move to the original sunny side (the side of the original heat pipe 22 facing the sun, see the attached figure). Figure 6 and attached Figure 7 During the shielding period, the hail detection unit 63 drives the arc cover 3 to move and adjust (according to the incident angle of the hail), so as to control the arc cover 3 to have the best shielding angle for the hail (the hail incident angle and the centroid line of the arc cover 3 are on the same straight line).

[0094] Please refer to the attached Figure 1 In a specific implementation of this embodiment, the first driving component 4 includes:

[0095] A gear ring 41, wherein the gear ring 41 coincides with the axis of the arc-shaped cover 3, and the gear ring 41 is arranged (for example, key-connected, interference-connected, or pin-connected) on the outer periphery of the arc-shaped cover 3;

[0096] A first transmission gear 42, wherein the first transmission gear 42 is meshed with the gear ring 41;

[0097] The first motor 43 has the first transmission gear 42 disposed on its output shaft. When the first motor 43 is powered on and its output shaft rotates, the gear ring 41 is driven to rotate via the first transmission gear 42 .

[0098] In a specific implementation of this embodiment, the gear rings 41 on the outer sides of the plurality of heat pipes 22 mesh with each other and are driven uniformly by the first transmission gear 42 ; in this implementation, one first motor 43 and one first transmission gear 42 are each provided.

[0099] In a specific implementation of this embodiment, the diameter of the gear ring 41 is greater than or equal to the diameter of the first transmission gear 42 .

[0100] In a specific implementation of this embodiment, it also includes a power supply component (not shown in the figure), which provides electrical energy to the first motor 43;

[0101] The energy supply component is a storage battery (such as a lithium battery),

[0102] Alternatively, the energy supply component is a solar panel (not shown in the figure), which uses solar energy to generate electricity (regardless of the angle of incidence of the sun at any time, the projection of the solar panel will not block the heat pipe 22) to supply power to the first motor 43, or stores the generated electricity in a battery and supplies power to the first motor 43 via the battery.

[0103] In a specific implementation of this embodiment, the first motor 43 is a DC motor; the first motor 43 can realize forward and reverse rotation under the forward and reverse currents supplied by the energy supply component.

[0104] In a specific implementation of this embodiment, the first motor 43 is an AC motor; the first motor 43 can realize forward and reverse rotation under the current of different phase sequences supplied by the energy supply component.

[0105] Please refer to the attached Figure 1 In a specific implementation of this embodiment, the heat pipe type solar vacuum collector evaporator further includes: a vacuum tube 23, the vacuum tube 23 is sleeved on the outer periphery of the heat pipe 22, and the axis of the vacuum tube 23 coincides with the axis of the heat pipe 22; one end of the vacuum tube 23 is connected to the housing 2 or the heat pipe 22, and the other end of the vacuum tube 23 is smooth and closed;

[0106] In terms of numerical value, the radius of the vacuum tube 23 is larger than the distance between the intersection line where the focusing focus of the reflective film 31 is located and the axis of the arc cover 3 .

[0107] In the present invention, by setting the size design of the vacuum tube 23, the reflected sunlight energy can act more on the heat pipe 22 for absorption, while avoiding the infrared radiation of the heat of the heat pipe, ensuring the high efficiency of heat energy utilization.

[0108] When the device provided by the present invention is working, solar energy is absorbed by the heat pipe 22 in the vacuum tube 23, and heat is transferred to the heat exchange main pipe 21 of the shell 2 under the action of the heat pipe 22. The working fluid entering through the working fluid inlet is heated by the heat exchange main pipe 21 and then discharged from the working fluid outlet, thereby realizing heat exchange.

[0109] In a specific implementation of this embodiment, the vacuum tube 23 is a glass tube;

[0110] The vacuum tube 23 includes an inner tube and an outer tube, and the space between the inner tube and the outer tube is in a vacuum state; the outer surface of the inner tube (the surface of the inner tube facing the outer tube) is coated with a selective absorption coating for absorbing solar radiation. This coating has a high absorption rate for solar radiation (efficiently absorbs solar radiation energy) and a low emissivity for long-wave radiation such as infrared (reducing the thermal radiation loss of the heat pipe 22).

[0111] In a specific implementation of this embodiment, the vacuum tube 23 is arranged between the arc cover 3 and the heat pipe 22; the arc cover 3 reflects and concentrates the sunlight onto the vacuum tube 23 and / or the heat pipe 22; when the weather is bad (snowing, hail, or foreign matter such as sand and dust on a windy day), the arc cover 3 is rotated from the bottom side (the original non-sunny side) to the upper side (the original sunny side) to block hail or other foreign matter, protect the vacuum tube 23 and the heat pipe 22, and avoid accidental damage due to impact.

[0112] In a specific implementation of this embodiment, the axes of the arc cover 3, the vacuum tube 23 and the heat pipe 22 coincide with each other;

[0113] In terms of position, the arc cover 3, the vacuum tube 23 and the heat pipe 22 are arranged from outside to inside in sequence.

[0114] In a specific implementation of this embodiment, one end of the vacuum tube 23 is connected to the shell 2, and the vacuum tube 23 is sleeved on the outside of the heat pipe 22 and the vacuum tube 23 does not contact the heat pipe 22, so that the vacuum tube 23 is integrated with the heat pipe (the vacuum tube 23 will not rotate relative to the heat pipe 22), and the other end of the vacuum tube 23 (the closed end of the vacuum tube 23) is closed.

[0115] In another specific implementation of this embodiment, one end of the vacuum tube 23 is connected to the heat pipe 22, so that the vacuum tube 23 is integrated with the heat pipe (the vacuum tube 23 will not rotate relative to the heat pipe 22), and the other end of the vacuum tube 23 (the closed end of the vacuum tube 23) is closed.

[0116] Numerically, the radius of the vacuum tube 23 is greater than the distance between the intersection of the focusing focus of the reflective film 31 and the axis of the arc cover 3.
