Abstract

The present disclosure provides a heat dissipation module and a charging base to which the heat dissipation module is applied. The heat dissipation module comprises a heat conduction part, a medium part comprising a heat dissipation medium, the heat dissipation medium being in contact with a first end of the heat conduction part, and a mounting part connected with the heat conduction part, and the heat dissipation module is detachably mounted on the charging base through the mounting part. When the heat dissipation module is mounted on the charging base, the medium part is located outside the charging base, and a second end of the heat conduction part is in contact with a heat generating part inside the charging base. The heat conduction efficiency of the heat conduction part is higher than that of the heat generating part, and the heat capacity of the heat dissipation medium is higher than that of the heat generating part, so that the heat inside the charging base can be conducted to the heat dissipation medium through the heat conduction part, and then buffered and dissipated to the outside through the heat dissipation medium, thereby achieving passive heat dissipation of the charging base. The heat dissipation module is an independent module, and only needs to add a heat dissipation interface to the charging base body to realize the optional function, which is convenient for late installation and maintenance.

Description

Technical Field

[0001] This disclosure relates to the field of charging dock technology, and more specifically, to a heat dissipation module and the charging dock in which it is applied. Background Technology

[0002] In existing technology, electric vehicles have charging sockets suitable for mating with charging guns. These charging sockets include power terminals for transmitting power. One end of the power terminal on the charging socket mates with the mating terminal on the charging gun, and the other end of the power terminal is connected to a cable via a busbar. To meet market demands, the fast charging power of electric vehicles is gradually increasing, leading to an exponential increase in the heat dissipation requirements of electric vehicles. To address the temperature rise problem caused by high-power charging, existing charging solutions generally employ a liquid cooling circulation system located at the charging gun end for cooling. However, the charging socket end (inlet) lacks suitable heat dissipation methods, and its current carrying capacity remains limited, making it difficult to achieve higher charging power. Utility Model Content

[0003] To address at least some of the aforementioned problems and deficiencies in the prior art, this disclosure proposes a novel heat dissipation module and charging base suitable for electric vehicle charging bases. This heat dissipation module uses a heat-conducting part and a heat dissipation medium to conduct heat from the interior of the charging base to the exterior and gradually release it, thereby reducing the overall temperature rise of the charging base, overcoming the limitations of the charging base on charging power, and thus improving the performance of electric vehicles and increasing the current-carrying capacity of the charging base.

[0004] Based on this, the first aspect of this disclosure provides a heat dissipation module for a charging dock. The heat dissipation module includes: a heat-conducting part; a medium part including a heat dissipation medium, the heat dissipation medium being in contact with a first end of the heat-conducting part; and a mounting part connected to the heat-conducting part. The heat dissipation module is detachably mounted to the charging dock via the mounting part. When the heat dissipation module is mounted to the charging dock, the medium part is located outside the charging dock, and the second end of the heat-conducting part is in contact with a heat-generating part inside the charging dock, so that the heat inside the charging dock can be conducted and stored to the heat dissipation medium via the heat-conducting part, and then dissipated to the outside via the heat dissipation medium.

[0008] In a preferred embodiment of the first aspect of this disclosure, the mounting portion is provided with a sealing element, and when the heat dissipation module is detachably mounted on the charging base, the sealing element simultaneously achieves a sealed connection between the heat dissipation module and the charging base.

[0009] In a preferred embodiment of the first aspect of this disclosure, the medium section includes a medium tank containing the heat dissipation medium, and the medium tank and the mounting section are integrally injection molded.

[0010] In a preferred embodiment of the first aspect of this disclosure, the medium tank is further provided with an active heat dissipation structure, which includes a fan or a coolant circulation pipe.

[0012] A second aspect of this disclosure provides a charging dock, comprising: a charging dock body having a heat dissipation interface thereon; and the aforementioned heat dissipation module, which cooperates with the heat dissipation interface and is detachably mounted on the charging dock body.

[0013] In a preferred embodiment of the second aspect of this disclosure, the charging dock further includes a plug for engaging with the heat dissipation interface to be detachably mounted on the charging dock body, so as to seal and protect the internal components of the charging dock when the heat dissipation module is not installed.

[0027] The implementation and use of the embodiments are discussed in detail below. However, it should be understood that the specific embodiments discussed are merely illustrative of particular ways of implementing and using this disclosure, and are not intended to limit the scope of this disclosure. The terms used when describing the various components, such as upper end, lower end, left side, right side, top, bottom, etc., are not absolute but relative. These terms are appropriate when the various components are arranged as shown in the figures, but they change accordingly when the positions of the various components in the figures change.

[0028] As mentioned above, to address the technical problem of poor heat dissipation performance of charging sockets in electric vehicles in the prior art, improve the vehicle's charging power, and solve other problems caused by temperature rise, such as safety aging, this disclosure proposes a heat dissipation module and a charging socket suitable for electric vehicles. This heat dissipation module rapidly conducts heat from inside the charging socket to an external heat dissipation medium via a heat-conducting part, and the heat dissipation medium then slowly releases the heat to the surrounding environment. This heat dissipation module can effectively improve the heat dissipation performance of the charging socket, enabling it to charge at a higher power, improving vehicle charging efficiency and user experience.

[0029] refer to Figure 1a , Figure 1b , Figure 2a and Figure 2b This disclosure provides an embodiment of a charging dock 10, which includes a heat dissipation module 100 and a charging dock body 200, with the heat dissipation module 100 mounted on the charging dock body 200. In some examples, the heat dissipation module 100 is detachably mounted on the charging dock body 200, for example, by means of a snap-fit ​​structure or threaded fitting. In other examples, the charging dock 10 also includes a plug 400, which is detachably mounted on the charging dock body 200 when the heat dissipation module is not mounted thereon, to seal and protect the internal components of the charging dock. Users can selectively install the heat dissipation module or the plug according to product requirements, improving the flexibility of product use. In some examples, the charging dock body 200 has a heat dissipation interface 202 for inserting the heat dissipation module 100 or the plug 400. In some examples, the charging dock body 200 includes two heat dissipation interfaces 202, which are symmetrically arranged on both sides of the charging dock body 200, and each heat dissipation interface allows for the insertion of one heat dissipation module 100. The more heat dissipation modules there are, the higher the heat dissipation efficiency of the charging dock. The specific number installed can be flexibly set according to product needs, and this disclosure does not limit it. The heat dissipation interface should preferably be located near the heat-generating parts inside the charging dock, such as near the busbar or terminals.

[0030] In some examples, the heat dissipation module 100 includes a heat-conducting part 102, a medium part 104, and a mounting part 105. The medium part 104 includes a heat dissipation medium that contacts a first end of the heat-conducting part 102. The mounting part 105 is connected to the heat-conducting part 102. The heat dissipation module 100 is detachably mounted on the charging dock body 200 via the mounting part 105. When the heat dissipation module 100 is mounted on the charging dock body 200, the medium part 104 is located outside the charging dock body 200, and the second end of the heat-conducting part 102 contacts a heat-generating part (e.g., a busbar and / or a terminal) inside the charging dock body 200. The heat conduction efficiency of the heat-conducting part is higher than that of the heat-generating part, and the heat capacity of the heat dissipation medium is higher than that of the heat-generating part. This allows the heat inside the charging dock body to be conducted and stored in the heat dissipation medium via the heat-conducting part, and then buffered and dissipated to the outside via the heat dissipation medium, thus achieving passive heat dissipation of the charging dock.

[0031] In some examples, the medium section 104 is integrally cast concrete, with the heat-conducting section 102 partially embedded within it. In some examples, the medium section 104 includes a medium tank containing a heat-dissipating medium. The medium tank is preferably made of a material and structure that facilitates heat dissipation. In some examples, the medium tank may be made of materials such as plastic or metal. In some examples, when the heat-dissipating medium is a gas or liquid, the medium tank may have a sealed structure. When the heat-dissipating medium is a solid, the medium tank may have an open heat-dissipating structure.

[0032] In some examples, the media tank and the mounting section are separate components. In other examples, the media tank and the mounting section are injection molded as a single unit, which simplifies the manufacturing process and reduces production costs.

[0033] In some examples, the heat-conducting part 102 is used as an insert and is injection molded with the mounting part 105. The heat-conducting part 102 is partially embedded in the mounting part 105, which helps to enhance the overall structural strength of the product. The connection between the heat-conducting part and the mounting part is well sealed, reducing assembly steps and lowering production costs.

[0034] In some examples, the mounting part 105 is provided with a snap-fit ​​structure 1052, which, by cooperating with the slot structure 206 on the charging dock body 200, enables detachable installation between the heat dissipation module 100 and the charging dock body 200. In other examples, the snap-fit ​​structure and the slot structure between the mounting part 105 and the charging dock body 200 can be interchanged. In still other examples, the heat dissipation module 100 can also use other mounting structures to achieve detachable installation with the charging dock body, for example, by threaded fittings. This embodiment preferably uses a snap-fit ​​structure, which only requires inserting the heat dissipation module into the heat dissipation interface to complete the installation, making it simple and quick, and providing users with a good installation experience.

[0035] In some examples, the mounting portion 105 is provided with a seal 108. When the heat dissipation module 100 is detachably mounted on the charging base body 200, the seal 108 simultaneously achieves a sealed connection between the heat dissipation module 100 and the charging base body 200. In some examples, the mounting portion 105 is provided with a sealing groove 1054. The seal 108 is fitted onto the sealing groove 1054 of the mounting portion 105, and achieves a seal on the charging base body when the heat dissipation module 100 is inserted into the heat dissipation interface 202, preventing moisture, dust, and other impurities from entering and protecting the internal components of the charging base body.

[0036] In some examples, the charging dock 10 includes a plug 400, which detachably mounts to the charging dock body 200 in conjunction with the heat dissipation interface 202. When the heat dissipation module is not installed on the charging dock body 200, the plug 400 can be installed to seal and protect the internal components of the charging dock. In some examples, the plug 400 has a sealing element 402 for sealing the heat dissipation interface 202. In some examples, the plug 400 has a snap-fit ​​structure 404 that engages with the slot structure 206 on the charging dock body for detachable installation. Users can flexibly choose to install either the plug 400 or the heat dissipation module 100 on the charging dock body 200 according to their actual needs. For example, a heat dissipation module can be installed in environments with high heat dissipation requirements, while a plug can be installed in environments with low heat dissipation requirements. Another example is that a plug can be installed to provide sealing protection when the heat dissipation module is damaged.

[0037] In some examples, the heat-conducting part 102 is preferably a metal heat-conducting part, that is, the heat-conducting part is made of a metal heat-conducting material, such as pure metal heat-conducting materials like copper or aluminum. Its heat conduction efficiency is significantly higher than that of the heating element inside the charging holder, allowing heat within the charging holder to be quickly conducted and stored in the heat dissipation medium. In some examples, the heat-conducting part 102 is preferably a bent rod-shaped structure (e.g., a heat-conducting rod or heat pipe), which increases the heat dissipation area of ​​the heat-conducting part and the contact area between the heat-conducting part and the heat dissipation medium, allowing heat to dissipate more quickly.

[0038] In some examples, the heat dissipation medium is preferably a medium with a large heat capacity, such as air, water, ethanol, or concrete. The heat capacity of the heat dissipation medium is significantly higher than that of the heat-generating part inside the charging base, which can absorb and store more heat with a lower temperature rise. Preferably, concrete heat dissipation medium does not require an additional medium tank and the heat-conducting part can be pre-embedded in it during casting, resulting in a stable structure, simple process, improved heat dissipation performance and current carrying capacity of the charging base while reducing production costs.

[0039] In some examples, the heat dissipation module 100 also includes an insulating thermally conductive sheet 106 deployed around the thermally conductive part 102 to provide an insulated connection between the thermally conductive part 102 and the interior of the charging dock. When the thermally conductive part is made of metal, it needs to be insulated from the interior of the charging dock to avoid leakage or other safety hazards. Heat within the charging dock is conducted from the terminals or busbar through the insulating thermally conductive sheet and the thermally conductive part 102 to a heat dissipation medium with a large heat capacity, and then slowly released to the surrounding environment by the heat dissipation medium. The insulating thermally conductive sheet 106 serves two main functions: first, to provide insulation, isolating the thermally conductive part 102 from the busbar or terminals of the charging dock to prevent direct contact that could cause leakage; second, to conduct heat, transferring the heat from the busbar to the thermally conductive part as quickly as possible.

[0040] In some examples, one side of the insulating thermally conductive sheet 106 is attached to the heat-conducting part, and the other side is attached to the busbar or terminal inside the charging socket. In other examples, the insulating thermally conductive sheet 106 encloses the heat-conducting part. In still other examples, the insulating thermally conductive sheet 106 is sandwiched between the heat-conducting part and the busbar.

[0041] In some examples, the media tank is equipped with heat dissipation fins, which can increase the contact area with the heat dissipation medium through multiple sheet-like metal structures, thereby improving heat conduction efficiency. Heat dissipation fins are suitable for any type of heat dissipation medium.

[0042] In this embodiment, the heat dissipation module 100 is an independent module. It can be installed as an optional feature by simply adding the required number of heat dissipation interfaces to the charging dock body. It is easy to install and maintain in the future. It has a simple structure and low cost. There is no liquid circulation inside the charging dock, which has higher safety compared to conventional liquid cooling circulation heat dissipation systems. When the charging dock is charging at high power for a short time, the peak heat stored inside is quickly absorbed and stored to the outside by a heat dissipation medium with high heat capacity, and then the stored heat is slowly released to the surrounding environment, which effectively reduces the overall temperature rise of the charging dock.

[0043] Figure 3 The diagram illustrates the temperature rise of an existing charging dock and a charging dock equipped with the heat dissipation module of this disclosure. The left side shows the temperature rise of the existing charging dock, where the temperature rises to the peak value T1 at time t1. The right side shows the temperature rise of the charging dock equipped with the heat dissipation module of this disclosure, where the temperature rises to the peak value T2 at time t2. Here, t2 is greater than t1, and T2 is much less than T1. Figure 3 This demonstrates intuitively the significant effect of this disclosure on reducing the rate and peak temperature rise of the charging dock.

[0044] refer to Figures 4 to 10 Another embodiment of this disclosure proposes a different charging dock 30. The charging dock 30 includes a heat dissipation module 300 and a charging dock body 200. The difference between this charging dock 30 and the charging dock 10 lies in the heat dissipation module. The main difference between the heat dissipation module 300 of the charging dock 30 and the heat dissipation module 100 of the charging dock 10 is that an active heat dissipation structure can be added to improve the heat dissipation capacity of the system.

[0045] Figure 4 This is a schematic diagram of the charging dock 30. Figure 5 A schematic diagram of the heat dissipation module 300 installed on the charging dock 30. Figure 6 This is a schematic diagram of a media tank without an active cooling structure. Figure 7 This is a schematic diagram of a media tank with an alternative active heat dissipation structure. Figure 8 This is a schematic diagram of a charging dock excluding the active cooling structure. Figure 9a and Figure 9b This is a schematic diagram of the connection structure between the heat-conducting part and the heat dissipation fins inside the medium tank. Figure 10 This is a schematic diagram of the connection structure between the heat-conducting part and the charging base.

[0046] refer to Figure 4 and Figure 5 The heat dissipation module 300 includes a heat-conducting part 302 and a medium tank 304. A first end of the heat-conducting part 302 is disposed inside the charging socket, and a second end of the heat-conducting part 302 is disposed outside the charging socket. The medium tank 304 is disposed outside the charging socket. The medium tank 304 contains a heat dissipation medium, which is in contact with the second end of the heat-conducting part. Heat inside the charging socket is dissipated to the outside via the heat-conducting part 302 and the heat dissipation medium.

[0047] Preferably, an active cooling structure 3042 can be installed on the media tank 304 to further improve the heat dissipation capacity of the heat dissipation module. In some examples, such as Figure 6 As shown, a fan 3042 can be optionally installed on the media tank 304. When no fan is installed, the air inside the media tank circulates naturally, and the cooling medium is passively cooled; when a fan is installed, the fan rotation drives the air convection inside the media tank, achieving active cooling. In other examples, such as... Figure 7 As shown, a coolant circulation pipe 3042 can be optionally installed on the medium tank 304. When the coolant circulation pipe is not installed, a heat dissipation medium such as coolant, gel, or solid such as concrete can be added to the tank, and the heat dissipation medium will cool naturally, resulting in passive heat dissipation. When the coolant circulation pipe is installed, a coolant medium is added to the medium tank, and the heat can be carried away by circulating in the pipe, achieving active heat dissipation.

[0048] In some examples, the media tank 304 is provided with heat dissipation fins 3044. Figure 9a and Figure 9b The contact methods between the heat-conducting part 302 and the heat dissipation fins 3044 are shown from different angles. The large-area contact between the heat-conducting part 302 and the heat dissipation fins and heat dissipation medium is beneficial to improving the thermal conductivity of the product.

[0049] In some examples, the heat dissipation module 300 also includes an insulating thermally conductive sheet 306 for providing an insulated connection between the thermally conductive part 302 and the interior of the charging dock. The charging dock body 200 is provided with a busbar 204, through which heat from the terminals is conducted from the terminals via the busbar 204, the insulating thermally conductive sheet 306 and the thermally conductive part 302 to the heat dissipation medium in the medium tank, and then slowly released to the surrounding environment by the heat dissipation medium. Figure 10 A connection structure of busbar 204, insulating heat-conducting sheet 306 and heat-conducting part 302 is shown. One side of the insulating heat-conducting sheet is attached to the surface of one end of the heat-conducting part. After it is inserted into the charging base together with one end of the heat-conducting part, the other side of the insulating heat-conducting sheet is attached to the busbar, so that the heat in the charging base can be transferred from the busbar to the insulating heat-conducting sheet, and then from the insulating heat-conducting sheet to the heat-conducting part.

[0050] In some examples, both ends of the heat-conducting part 302 are provided with seals 308, which are used to seal the connection between the heat-conducting part and the heat dissipation interface of the charging base and the connection between the heat-conducting part and the medium tank, respectively, to prevent impurities from entering the charging base and to prevent the medium in the medium tank from leaking.

[0051] Optionally, the heat dissipation module 300 can be detachably installed on the charging dock body 200. The heat dissipation module 300 is an independent module; it can be installed simply by adding the required number of heat dissipation interfaces to the charging dock body, making subsequent installation and maintenance convenient. The media tank is located on the outside of the charging dock body, so even if a coolant circulation system is used, liquid leakage will not contaminate the inside of the charging dock, ensuring high safety. Multiple heat dissipation modes can be achieved by replacing accessories such as the media tank cover, meeting different user heat dissipation needs, offering high flexibility, good heat dissipation performance, and improving the user experience.

[0052] While this disclosure has been described with reference to specific examples, which are intended to be illustrative only and not to limit the disclosure, it will be apparent to those skilled in the art that changes, additions, or deletions may be made to the disclosed embodiments without departing from the spirit and scope of this disclosure.
