Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of thermal storage devices, specifically relating to an indoor thermal storage temperature regulation device. Background Technology
[0002] Maintaining a suitable indoor temperature environment is a common need in homes, agriculture, and industry. Currently, indoor temperature regulation mainly relies on two types of technologies: electric air conditioning is commonly used for cooling in summer, while heating in winter is achieved using the heating mode of air conditioners or by directly burning fossil fuels such as coal and natural gas. However, these conventional technological approaches face serious challenges. On the one hand, air conditioning systems are major energy consumers, and their large-scale operation puts enormous pressure on the power grid; on the other hand, burning coal and natural gas directly consumes fossil fuels, resulting in non-renewable energy sources, pollutants generated during operation, and greenhouse gas emissions. Based on the dual considerations of energy conservation and environmental protection, developing a more energy-efficient and environmentally friendly new temperature regulation solution is of great significance for promoting sustainable development in various fields. Utility Model Content
[0003] The purpose of this invention is to provide an energy-saving and environmentally friendly indoor thermal storage temperature regulation device that requires no electricity and does not consume non-renewable energy.
[0004] To achieve the above objectives, the present invention adopts the following technical solution: An indoor thermal storage temperature regulation device includes a movable support, on which a thermal storage box is mounted. The thermal storage box is filled with phase change material, and several heat-conducting sleeves are installed inside the thermal storage box. One end of the heat-conducting sleeve is open, and the other end is sealed. The opening of the heat-conducting sleeve extends outside the thermal storage box, and the outer wall of the heat-conducting sleeve is sealed to the thermal storage box. A gravity heat pipe is detachably connected to the heat-conducting sleeve via threads. Part of the gravity heat pipe is located inside the heat-conducting sleeve, and the other part of the gravity heat pipe extends out of the heat-conducting sleeve and out of the thermal storage box. The upper section of the gravity heat pipe is a condensation section, the middle section is an insulation section, and the lower section is an evaporation section. The several heat-conducting sleeves are located in the upper and lower parts of the thermal storage box, respectively. The heat-conducting sleeves located in the upper part of the thermal storage box house the evaporation section and insulation section of the gravity heat pipe, and the condensation section extends out of the thermal storage box. The heat-conducting sleeves located in the lower part of the thermal storage box house the condensation section and insulation section of the gravity heat pipe, and the evaporation section extends out of the thermal storage box.
[0005] Furthermore, the heat storage box is wrapped with an insulation layer.
[0006] Furthermore, the gravity heat pipe is a water-methanol working fluid gravity heat pipe.
[0007] Furthermore, the phase change material is a TD-OC composite phase change material.
[0008] Furthermore, the heat storage box is a rectangular box.
[0009] Furthermore, the angle between the length direction of the gravity heat pipe installed inside the heat-conducting sleeve at the top of the heat storage box and the top wall of the heat storage box is an acute angle, and the angle between the length direction of the gravity heat pipe installed inside the heat-conducting sleeve at the top of the heat storage box and the bottom wall of the heat storage box is an acute angle.
[0010] Furthermore, the movable support is a cuboid frame, and casters are provided under the cuboid frame.
[0011] This invention combines a gravity heat pipe with a phase change material (PCM), utilizing the thermal conductivity of the gravity heat pipe and the high heat storage capacity of the PCM to regulate indoor temperature. When the external temperature is high, heat is conducted through the gravity heat pipe into the PCM for storage; when the external temperature is low, the heat is released from the PCM, thus regulating the indoor temperature. This device is suitable for areas with large diurnal temperature variations. The gravity heat pipe in this invention is also detachable. By removing the gravity heat pipe and changing the number of heat pipes on the storage tank, the heat transfer capacity of the gravity heat pipe can be controlled, thereby regulating the rate of indoor temperature change. This invention is also easy to move and install, convenient to use, requires no electricity, and is energy-saving and environmentally friendly. Attached Figure Description

Detailed Implementation Example 1
[0013] like Figure 1-4The illustrated indoor thermal storage temperature regulating device includes a movable support 1, on which a thermal storage box 2 is mounted. The thermal storage box 2 is filled with a phase change material. Several heat-conducting sleeves 3 are installed inside the thermal storage box 2. One end of each heat-conducting sleeve is open, and the other end is sealed. The opening of the heat-conducting sleeve extends outside the thermal storage box 2. The outer wall of the heat-conducting sleeve 3 is sealed to the thermal storage box 2. A gravity heat pipe 4 is detachably connected to the heat-conducting sleeve 3 via threads. Part of the gravity heat pipe 4 is located inside the heat-conducting sleeve 3, and the other part extends outwards. The gravity heat pipe 4 has a condensation section 41 at the top, an insulation section 42 in the middle, and an evaporation section 43 at the bottom. Several heat-conducting sleeves 3 are located in the upper and lower parts of the heat storage box 2. The evaporation section 43 and the insulation section 42 of the gravity heat pipe 4 are installed inside the heat-conducting sleeve 3 located in the upper part of the heat storage box 2, and the condensation section 41 extends out of the heat storage box 2. The condensation section 41 and the insulation section 42 of the gravity heat pipe 4 are installed inside the heat-conducting sleeve 3 located in the lower part of the heat storage box 2, and the evaporation section 43 extends out of the heat storage box 2. The heat storage box 2 is wrapped with an insulation layer 5, which is 4 mm thick and is made of small bubble aluminum insulation blanket. The gravity heat pipe 4 is a water-methanol working fluid gravity heat pipe 4, with a total length of 85cm. The condensation section 41 is 30cm long, the adiabatic section 42 is 10cm long, and the evaporation section 43 is 45cm long. The inner diameter of the circular axial surface of the gravity pipe 4 is 12mm, and the outer diameter is 13mm. The volume ratio of water to methanol in the gravity heat pipe 4 is 13L:1L. The phase change material is a TD-OC composite phase change material. The heat storage box 2 is a cuboid box with a length of 55cm, a width of 55cm, and a height of 45cm. The angle between the length direction of the upper gravity heat pipe 4 and the top wall of the heat storage box 2 is an acute angle, and the angle between the length direction of the upper gravity heat pipe 4 and the bottom wall of the heat storage box 2 is an acute angle of 30°. The movable support 1 has a cuboid frame, and casters 6 are provided under the cuboid frame. The heat storage box 2 is also equipped with a handle 7.
[0014] During use, when the external ambient temperature is higher than 20℃, the working medium in the evaporation section 43 of the gravity heat pipe 4 at the bottom of the heat storage box begins to absorb external heat energy and change from liquid to vapor. The vapor rises to the condensation section 41 located in the heat storage box and condenses to release heat, thereby transferring heat from the external environment to the heat storage box 2 through the gravity heat pipe 4. The TD-OC composite phase change material in the heat storage box 2 absorbs heat and changes from solid to liquid. The phase change heat storage box stores heat, and the external ambient temperature decreases. During this heat storage process, the upper gravity heat pipe does not work. When the external ambient temperature is lower than 20℃, the internal temperature of the heat storage box is higher than the external temperature. The working medium in the evaporation section 43 of the gravity heat pipe 4 at the top of the heat storage box absorbs the heat stored in the heat storage box and vaporizes. The vapor rises to the condensation section 41 located in the external environment and condenses to release heat. The TD-OC composite phase change material in the heat storage box 2 changes from liquid to solid, and the external ambient temperature rises.
