Description

Technical Field

[0001] This utility model relates to the field of charging technology, and in particular to a high-efficiency heat dissipation mobile power supply. Background Technology

[0002] In existing technologies, power banks (portable chargers) experience temperature increases during charging, leading to slow charging, excessively long charging times, and a poor user experience. This is especially true in power banks with wireless charging capabilities, where the phone's charging coil is in close contact with the power bank's wireless charging coil (which is designed for efficient heat dissipation). Heat accumulates in the wireless charging coil area and cannot be quickly dissipated, causing the temperature at the phone's contact point with the coil to rise too rapidly, quickly reaching the temperature threshold that limits the wireless charging current. Current technologies, which simply add an aluminum sheet or heat dissipation film to the bottom of the wireless charging coil, are insufficient for efficient and rapid heat dissipation. Therefore, a power bank with improved heat dissipation is needed. Utility Model Content

Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout.

[0025] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0026] The principles behind battery heat generation during charging and discharging are mainly based on the following points: Chemical reactions generate heat: The chemical reactions occurring inside the battery are the primary cause of heat generation. During charging and discharging, the positive and negative electrode materials and the electrolyte inside the battery undergo chemical reactions. These reactions act as a stage for chemical reactions, continuously releasing heat energy. Especially when the battery is deeply charged and discharged, the chemical reactions are more intense, and the heat generated increases accordingly. Current flow generates heat: When current flows through the battery, due to the existence of internal resistance, according to Joule's law (the heat generated by current flowing through a conductor is proportional to the square of the current, the resistance, and the time of current flow), heat is generated when current flows through the resistance. This is also an important reason for battery heat generation during charging and discharging. Battery aging and changes in internal resistance: As the battery is used for longer periods, the internal materials and structure of the battery will change, such as the electrolyte drying out or sulfuric acid crystals forming and precipitating on the lead plates. These changes lead to an increase in the battery's internal resistance. Increased internal resistance means that under the same current, the heat generated by the battery will increase. External environment and heat dissipation conditions: The external ambient temperature also affects the battery's heat generation. When the external ambient temperature rises, the chemical reactions inside the battery become more active, and the heat generated increases accordingly. In addition, if the battery's heat dissipation conditions are poor, such as being enclosed in a sealed space or having an unreasonable heat dissipation design, the battery's heat cannot be effectively dissipated and will accumulate inside the battery.

[0027] Reference Figure 1 , Figure 2 and Figure 3The high-efficiency heat-dissipating mobile power bank in the first embodiment of this utility model includes: a housing 1, a charging device 2, a heat dissipation channel 3, and a heat dissipation device 4. The housing 1 restricts the cavity 11, and has an air inlet 12 and an air outlet 13. The air inlet 12 connects the inside and outside of the cavity 11, and the air outlet 13 connects the inside and outside of the cavity 11. By setting the air inlet 12 and the air outlet 13, air can enter into the cavity 11 and be discharged from the cavity 11. During the use of the high-efficiency heat-dissipating mobile power bank, the high-efficiency heat-dissipating mobile power bank will release heat, thereby making the temperature inside the cavity 11 higher than the outside temperature. Therefore, after the gas outside the cavity 11 enters the cavity 11 through the air inlet 12, it absorbs the heat inside the cavity 11, thus becoming a hotter gas and being discharged through the air outlet 13. The air inlet 12 and the air outlet 13 are respectively opened on two surfaces of the housing 1 spaced apart along a first direction, the first direction being the length direction of the housing 1. This allows the heat dissipation channel 3 to carry away more heat within the housing 1.

[0028] The charging device 2 is disposed within the chamber 11 and used for charging. The charging device 2 and the inner wall of the chamber 11 together define a heat dissipation channel 3, which connects the air inlet 12 and the air outlet 13, allowing air from outside the chamber 11 to pass through the heat dissipation channel 3. The heat dissipation device 4 includes a heat absorption part and a heat dissipation part. The heat dissipation part is disposed within the heat dissipation channel 3 and used for heat dissipation. The heat absorption part conducts heat with the heat dissipation part, and the heat absorption part absorbs heat from the charging device 2. During the charging and discharging process, the charging device 2 releases heat, causing the temperature inside the chamber 11 to rise. The heat dissipation channel 3, disposed within the chamber 11, connects the air inlet 12 and the air outlet 13, allowing air from outside the chamber 11 to pass quickly through the heat dissipation channel 3 and carry away the heat dissipated by the charging device 2 within the heat dissipation channel 3, thereby lowering the temperature of the power supply. Furthermore, the heat absorption part of the heat dissipation device 4 absorbs heat from the charging device 2 and conducts the absorbed heat to the heat dissipation part. Meanwhile, the heat dissipation unit is placed within the heat dissipation channel 3, making it easier for the gas flowing through the heat dissipation channel 3 to carry away the heat from the heat dissipation unit, thereby giving the high-efficiency heat dissipation power bank a better heat dissipation effect. The charging device 2 includes a battery 21 and a charging coil 23, which are electrically connected. The heat-absorbing part is thermally connected to at least one of the battery 21 and the charging coil 23, allowing the heat emitted by the battery 21 or the charging coil 23 to be quickly carried away by the heat-absorbing part, thus avoiding the phenomenon of insufficient heat dissipation when the heat source is close by.

[0029] According to some embodiments of this utility model, the air inlet 12 and the air outlet 13 are respectively opened on two opposite sides of the housing 1, and the heat dissipation channel 3 connects the air inlet 12 and the air outlet 13 in a straight line along a first direction, which is the length direction of the housing 1. The air inlet 12 and the air outlet 13 are vertically connected by the heat dissipation channel 3, allowing air to pass through the heat dissipation channel 3 more quickly and smoothly, resulting in a faster airflow velocity within the heat dissipation channel 3 and thus a better heat dissipation effect. In the prior art, to achieve more uniform and comprehensive heat dissipation, the heat dissipation channel 3 is usually curved within the chamber 11, allowing the gas passing through the heat dissipation channel 3 to absorb heat more fully. However, this reduces the flow velocity within the heat dissipation channel 3, thereby reducing heat dissipation efficiency. Therefore, after setting the vertical heat dissipation channel 3, a heat dissipation device 4 is installed. Through the cooperation of the heat dissipation device 4 and the heat dissipation channel 3, the charging device 2 can be dissipated sufficiently and evenly, and the efficiency of heat dissipation through the heat dissipation channel 3 can be improved.

[0030] According to some embodiments of this utility model, the heat dissipation device 4 includes a cooling plate 41, which is used for cooling. The cooling plate includes a cold side surface and a hot side surface. The cold side surface is a heat-absorbing part, and the hot side surface is a heat-dissipating part. By using the cooling plate 41, the temperature of the heat-absorbing part is reduced, thereby making the temperature of the heat-absorbing part even lower, so that the heat-absorbing part can more fully absorb the heat generated by the charging device 2. The cooling plate 41 transfers the heat to the heat dissipation part for release, thereby better improving the heat dissipation efficiency of the high-efficiency heat-dissipating mobile power bank. Furthermore, the outer surface of the shell 1 includes a charging surface, which is located at one end of the shell 1 in the thickness direction. The charging coil 23 and the cold side surface are both disposed on the side of the cavity 11 near the charging surface, and the hot side surface faces away from the charging surface. When using the charging coil 23 for wireless charging, the electrical appliance, such as a mobile phone, will be attached to the charging surface. The mobile phone is also a heat source. Disposing the cold side surface on the side of the cavity 11 near the charging surface can better absorb the heat emitted by various heat sources.

[0031] According to some embodiments of this utility model, the heat dissipation device 4 includes a heat sink 42. The end of the heat sink near the charging device 2 is a heat absorption part, and the end of the heat sink away from the charging device 2 is a heat dissipation part. The heat sink 42 includes multiple blades 44, which are spaced apart on the heat dissipation part along a second direction. The blades 44 extend along a first direction, and the second direction is the width direction of the housing 1. By providing multiple blades 44, the contact area between the heat sink 42 and the gas in the heat dissipation channel 3 is increased, thereby enabling the heat sink 42 to transfer heat to the gas passing through the heat dissipation channel 3 with higher efficiency.

[0032] According to some embodiments of this utility model, the heat dissipation device 4 includes a cooling plate 41 and a heat sink 42. The cooling plate 41 includes a cold side surface and a hot side surface. The cold side surface is a heat-absorbing part. The heat sink 42 includes a plurality of blades 44, which are spaced apart on the hot side surface along a second direction. The blades 44 extend along the first direction, which is the width direction of the housing 1. The heat sink is a heat dissipation part. This achieves a better heat dissipation effect.

[0033] According to some embodiments of this utility model, multiple blades 44 jointly define multiple air ducts 43, and the air ducts 43 connect the air inlet 12 and the air outlet 13 along a first direction. The air ducts 43 defined by the blades 44 not only allow the gas to flow more smoothly in the heat dissipation channel 3, but also allow the gas to carry away heat more evenly from the blades 44.

[0034] According to some embodiments of this utility model, the heat dissipation device 4 further includes a heat-conducting plate 45, which includes a first part and a second part. The first part is attached to the charging device 2, and the second part is attached to the heat-absorbing part. By attaching the first part of the heat-conducting plate 45 to the charging device 2, heat can be absorbed from multiple locations on the charging device 2. This not only allows for more uniform absorption of heat from the charging device 2 across multiple areas, but also improves the heat conduction efficiency, thereby enabling the charging device 2 to dissipate heat more effectively.

[0035] The heat-conducting plate 45 uses materials with high thermal conductivity. Specific solid materials with high thermal conductivity mainly include metals and some non-metallic compounds, as follows: Metals: Silver, copper, aluminum, and gold are all metals with high thermal conductivity. Among them, silver has the highest thermal conductivity, followed by copper, and then gold. These metals are widely used in the manufacture of appliances and equipment requiring efficient thermal conductivity, such as radiators and heat pipes. Non-metallic compounds: Diamond, aluminum nitride, and silicon carbide also have high thermal conductivity. Diamond has extremely high thermal conductivity, about five times that of copper, and is often used for heat dissipation in electronic devices and jewelry identification. Aluminum nitride is a material with electrical insulation and high thermal conductivity, and can be used to make electrical insulators for mechanical chips. Silicon carbide, due to its hardness and durability, is often used in automotive brakes, turbine components, etc. Thermal conduction is the process of heat being transferred from a high-temperature object to a low-temperature object through direct contact. The thermal conductivity of solid materials depends on their internal microstructure and material composition. The high thermal conductivity of metals is mainly attributed to the free electrons within them. Free electrons in metals can move freely within the metal lattice. When one end of the metal is heated, the heat accelerates the free electrons, which then rapidly transfer heat to the other end, thus achieving rapid heat conduction. The thermal conductivity of non-metallic compounds depends on their internal atomic or molecular structure. For example, carbon atoms in diamond are tightly bound together by covalent bonds, forming a very stable lattice structure. This structure allows heat to be rapidly transferred through lattice vibrations and interatomic interactions when diamond is heated. In general, solid materials with high thermal conductivity typically possess a stable lattice structure, good electronic conductivity, or tight atomic bonding; these factors collectively determine the material's thermal conductivity. When selecting thermally conductive materials, in addition to considering thermal conductivity, factors such as cost, processability, corrosion resistance, and mechanical strength must also be considered to meet specific application requirements. Therefore, the heat-conducting plate 45 is made of copper or a copper alloy, which not only gives it good thermal conductivity but also good deformability, allowing it to adhere more tightly to the charging device 2.

[0036] According to some embodiments of this utility model, the charging device 2 includes a battery 21 and a charging coil 23, which are electrically connected. A heat-conducting plate 45 is attached to the battery 21, and the charging coil 23 is disposed on the side of the heat-conducting plate 45 facing away from the battery 21. Wireless charging technology is based on the principle of electromagnetic induction, transmitting electrical energy through the interaction of the magnetic fields of two coils. During the charging process, if the energy conversion efficiency of the wireless charging system is low, the portion that is not effectively converted into electrical energy will be released as heat, causing the phone and charger to heat up. During wireless charging, the electromagnetic field between the charger and the phone will generate a certain amount of interference, which may also lead to heat generation. High-power wireless charging devices, such as fast charging functions, can shorten charging time but also generate more heat. As can be seen from the principle of wireless charging, wireless charging releases more heat, and in order to improve the charging efficiency of wireless charging, a high-efficiency heat-dissipating power bank and the device need to be attached together during charging. Taking wireless charging of a mobile phone using a high-efficiency heat-dissipating power bank as an example, the phone needs to be placed against the charging coil 23 on the casing 1 for charging. At this time, not only does the high-efficiency heat-dissipating power bank dissipate heat, but the phone also generates considerable heat that needs to be dissipated. When the two heat sources are close to each other, it becomes even more difficult for the phone and the high-efficiency heat-dissipating power bank to dissipate heat. Therefore, the charging coil 23 is placed on the side of the heat-conducting plate 45 facing away from the battery 21, allowing the heat generated by the charging coil 23 to be released more quickly through the heat-conducting plate 45.

[0037] According to some embodiments of this utility model, the charging device 2 further includes a circuit board 22 and a charging port. The circuit board 22 is disposed at one end of the battery 21 along a first direction and is electrically connected to the battery 21. The charging port is electrically connected to the circuit board 22, and at least a portion of the charging port is exposed outside the cavity 11. When the thickness of the high-efficiency heat-dissipating power bank is large, the heat dissipation inside the power bank will deteriorate. Therefore, by arranging the circuit board 22 along the first direction, i.e., the length direction of the high-efficiency heat-dissipating power bank, the thickness of the high-efficiency heat-dissipating power bank is reduced, thereby improving the heat dissipation effect of the high-efficiency heat-dissipating power bank.

[0038] According to some embodiments of this utility model, a fan is provided inside the heat dissipation channel 3 to drive the air circulation within the heat dissipation channel 3. By increasing the air circulation speed within the heat dissipation channel 3 through the fan, the air passes through the heat dissipation channel 3 at a faster speed, thereby further improving the efficiency of heat removal by the air within the heat dissipation channel 3.

[0039] Furthermore, the space within chamber 11 can be divided into two regions along the first direction: a first region and a second region adjacent to each other along the first direction. The battery 21 is placed in the first region, where heat dissipation is greater. Therefore, a heat dissipation device 4 is installed on one side of the battery 21 along the second direction, i.e., the width direction of the high-efficiency heat-dissipating power bank. The side of the battery 21 facing the heat dissipation device 4, together with the internal structure of the housing 1, forms a heat dissipation channel 3. This heat dissipation channel 3 is vertically arranged along the first direction. This not only improves the space utilization within the housing 1, allowing for a larger battery 21 and thus increasing the energy density of the high-efficiency heat-dissipating power bank, but also directly exposes one side of the battery 21 within the heat dissipation channel 3, resulting in better heat dissipation. The heat dissipation channel 3, formed by the side of the battery 21 facing the heat dissipation channel 3 and the internal structure of the housing 1, extends through the first and second regions. The heat dissipation device 4 is located in the part of the heat dissipation channel 3 in the first region. The fan and circuit board 22 are placed together in the second region to ensure a large airflow within the heat dissipation channel 3. To avoid interference between the fan and the heat dissipation device 4, the fan is placed in the part of the heat dissipation channel 3 in the second region. Therefore, the heat dissipation efficiency of the fan location is not as high as that of the heat dissipation device 4 location. The heat dissipation of the circuit board 22 is relatively small. Therefore, the fan and circuit board 22 are placed together in the second region.

[0040] According to some embodiments of this utility model, both the air inlet 12 and the air outlet 13 are equipped with filter devices 5, which are used to filter the gas. In order to prevent impurities or moisture in the air from entering the heat dissipation channel 3, filter devices 5 are provided to filter the air, thereby making the air entering the heat dissipation channel 3 purer.

[0041] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
