A battery charging cooling structure

Abstract

This utility model discloses a battery charging and cooling structure, including a first housing and a second housing that cooperate with each other. Several sets of arranged frame-shaped heat dissipation sections are installed inside the first and second housings. The upper and lower sides of the frame-shaped heat dissipation sections are elastically set for clamping the battery vertically. A vent cover is installed on the upper end of the second housing, and a cooling fan is installed on the vent cover. The upper end of the second housing also has several sets of air inlets corresponding to the frame-shaped heat dissipation sections. The cooling fan drives gas to move from the air inlets into the interior of the frame-shaped heat dissipation sections, and the gas moves around the frame-shaped heat dissipation sections once before being discharged. Compared with the prior art, the advantage of this utility model is that by installing the battery inside the frame-shaped heat dissipation section, the cooling fan generates airflow from the outside into the frame-shaped heat dissipation section. The airflow moves outward after circling the frame-shaped heat dissipation section, without directly contacting the battery, thus avoiding dust contact with the battery and improving safety.

Description

Technical Field

[0001] This utility model relates to the field of battery charging and cooling technology, and in particular to a battery charging and cooling structure. Background Technology

[0002] The charging process of a personal mobility vehicle battery is essentially an electrochemical reaction. When current flows through it, heat is generated. Long-term or repeated exposure to high temperatures will significantly shorten the battery's lifespan and cause rapid capacity decay. In extreme cases, excessively high temperatures may trigger thermal runaway reactions inside the battery, posing a risk of fire or explosion. High temperatures may also increase the battery's internal resistance and slow down the charging speed.

[0003] Therefore, cooling is required during battery charging. In CN207558881U, entitled "Battery Box and Its Cooling System", a cooling fan is mentioned to draw heat out of the battery box. Although it can draw air into multiple parts at the same time, there are still problems. When heat is discharged, airflow is necessary. If there is dust or impurities in the air, they will move into the battery box. The air may contain metal dust or conductive particles after being damp. If this dust accumulates on the battery terminals, circuit boards, connectors or cable interfaces, it may cause micro short circuits or local leakage, resulting in safety problems.

[0004] Therefore, when a cooling fan is needed to dissipate heat, dust in the air should be prevented from coming into contact with the battery. Utility Model Content

The frame-shaped heat dissipation parts have elastic settings on the upper and lower sides for clamping the battery in the vertical direction.

[0007] A gas collection cover is installed on the upper end of the second housing, and a cooling fan is installed on the gas collection cover. The upper end of the second housing also has several sets of air inlets corresponding to the frame-shaped heat dissipation section. The cooling fan drives the gas to move from the air inlet to the inside of the frame-shaped heat dissipation section, and the gas moves around the frame-shaped heat dissipation section and is discharged.

[0008] A further preferred embodiment of this utility model is: the frame-type heat dissipation part includes an outer frame 1 and an outer frame 2 respectively fixed inside the housing 1 and the housing 2, and the opposite sides of the outer frame 1 and the outer frame 2 respectively have an inner frame 1 and an inner frame 2 that can be stretched and changed, and the inner frame 1 and the inner frame 2 are used to support the battery.

[0009] The inner frame 1 and the inner frame 2 are connected at one end, and the outer frame 1 has an exhaust hole on its outer side for discharging gas.

[0010] A further preferred embodiment of this utility model is as follows: outer frame one and outer frame two are respectively sealed to the inner walls of housing one and housing two, inner frame one is slidably sleeved on the upper end of outer frame one, inner frame two is slidably sleeved on the lower end of outer frame two, and the contact surfaces of inner frame one and outer frame one are tightly fitted, and the contact surfaces of inner frame two and outer frame two are tightly fitted.

[0012] A further preferred embodiment of this utility model is: transmission channel one and transmission channel two are respectively fixed on opposite surfaces of inner frame one and inner frame two near one end, transmission channel one and transmission channel two are nested and connected to each other, and their contact surfaces are tightly fitted.

[0013] A further preferred embodiment of this utility model is: the discharge hole is located at the end of the outer frame one that is far away from the transmission channel one, the corresponding air inlet is connected to the corresponding outer frame two, and the air inlet and the transmission channel two are respectively close to the two ends of the outer frame two.

[0014] The gas moving inward from the air inlet moves in a "C" shape along the frame-shaped heat dissipation section and is then discharged from the outlet.

[0015] A further preferred embodiment of this utility model is as follows: multiple sets of mounting holes are provided on the inner walls of both sides of the first and second housings, and an outer limiting layer is provided on the inner walls of both sides of the first and second housings. The outer end of the outer limiting layer has a mounting shaft, which is inserted into the corresponding mounting hole. The outer limiting layer is used to limit the longitudinal direction of the frame-shaped heat dissipation part.

[0016] A further preferred embodiment of this utility model is: the outer limiting layer inside the first shell and the second shell respectively clamps the first inner frame and the second inner frame.

[0021] 2. The frame-type heat dissipation part has an elastic expansion and contraction function, which allows the frame-type heat dissipation part to be in close contact with the battery, thereby improving the heat conduction effect. At the same time, even if there are different height differences between the batteries, it can make contact with batteries of different heights, increasing the contact area and enhancing the heat dissipation effect.

[0032] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0033] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it may not be further defined and explained in subsequent figures.

[0034] This embodiment mainly describes a battery charging cooling structure. Please refer to [link / reference]. Figures 1-8 Specifically, the following applies: Existing technologies utilize cooling fans to dissipate heat from the battery pack. The main function of these fans is to generate airflow, which carries away the heat generated by the battery. However, this airflow is not always clean; it may contain metal dust or conductive particles that become damp, potentially causing micro-short circuits or localized leakage, leading to safety issues. Therefore, a battery charging cooling structure is proposed, such as… Figures 1-3 As shown, it includes a housing 1 and a housing 2 that cooperate with each other. Several sets of frame-shaped heat dissipation parts 5 are installed inside the housing 1 and the housing 2. The frame-shaped heat dissipation parts 5 have elastic settings on the upper and lower sides for clamping the battery in the vertical direction.

[0035] The upper end of the housing 2 is equipped with a gas collection cover 3, and a cooling fan 4 is installed on the gas collection cover 3. The upper end of the housing 2 also has several sets of air inlets 21 corresponding to the frame-shaped heat dissipation section 5. The cooling fan 4 drives the gas to move from the air inlet 21 to the inside of the frame-shaped heat dissipation section 5, and the gas moves around the frame-shaped heat dissipation section 5 and is discharged.

[0036] Specifically, the main function of the frame-shaped heat dissipation part 5 is to form an airflow channel, allowing the airflow to move along the frame-shaped heat dissipation part 5 without directly contacting the battery. At the same time, the frame-shaped heat dissipation part 5 has an elastic function, which can fit with the battery to a certain extent, thus ensuring that the heat of the battery is transferred to the frame-shaped heat dissipation part 5, and the gas moves along the frame-shaped heat dissipation part 5 to carry away the heat.

[0037] like Figures 3-5The frame-type heat dissipation part 5 is shown in detail. The frame-type heat dissipation part 5 includes an outer frame 51 and an outer frame 53 that are respectively fixed inside the housing 1 and the housing 2. The opposite sides of the outer frame 51 and the outer frame 53 have an inner frame 52 and an inner frame 54 that can be stretched and changed. The inner frame 52 and the inner frame 54 are used to support the battery.

[0038] The inner frame 1 52 and the inner frame 2 54 are connected at one end, and the outer frame 1 51 has an exhaust hole 58 for discharging gas on its outer side.

[0039] Specifically, the frame-type heat dissipation part 5 includes an outer frame 51, an outer frame 53, an inner frame 52, and an inner frame 54. The outer frame 51 is sleeved with the inner frame 52, and the outer frame 53 is sleeved with the inner frame 54. It should be noted that during the sleeve connection, the outer frame 51 and the inner frame 52, as well as the outer frame 53 and the inner frame 54, can expand and contract without separating the outer frame 51 and the inner frame 52, or the outer frame 53 and the inner frame 54. This prevents the inner frame 52 from detaching from the outer frame 51 and the inner frame 54 from detaching from the outer frame 53. It should also be noted that the expandable and contractible design, and the fact that they do not detach through fastening, are all existing technologies.

[0040] like Figure 5 The following is a further explanation of the structure of the frame-type heat dissipation part 5. The outer frame 1 51 and the outer frame 2 53 are respectively sealed to the inner walls of the housing 1 and the housing 2. The inner frame 1 52 is slidably sleeved on the upper end of the outer frame 1 51, and the inner frame 2 54 is slidably sleeved on the lower end of the outer frame 2 53. The contact surfaces of the inner frame 1 52 and the outer frame 1 51 are tightly fitted, and the contact surfaces of the inner frame 2 54 and the outer frame 2 53 are tightly fitted.

[0041] Specifically, in order to minimize gas leakage during airflow, outer frame 51 and outer frame 53 are sealed to the inner walls of housing 1 and housing 2 respectively using adhesive. Although inner frame 52 and inner frame 54 are slidable, the exhaust hole 58 prevents air pressure from being generated inside the frame-type heat dissipation part 5 when airflow passes through, allowing airflow to exit through the exhaust hole 58 and preventing airflow from leaking out from the mating position of inner frame 52 and inner frame 54.

[0042] like Figures 4-5 Further explanation is given for the outer frame 51, outer frame 53, inner frame 52, and inner frame 54. The outer frame 51 and outer frame 53 have the same shape, both being rectangular and running vertically through the interior. The inner frame 52 and inner frame 54 have the same shape, also being rectangular, with one end closed on the outside.

[0043] Specifically, outer frame 51 and inner frame 52, along with outer frame 53 and inner frame 54, form two tubular structures for airflow transport.

[0044] like Figure 4 As shown, in order to connect the inner frame 1 52 and the inner frame 2 54 and to allow them to expand and contract, transmission channels 1 56 and 2 57 are fixed on the opposite sides of the inner frame 1 52 and the inner frame 2 54 near one end, respectively. The transmission channels 1 56 and 2 57 are connected to each other and their contact surfaces are tightly fitted.

[0045] Specifically, by setting transmission channel 1 56 and transmission channel 2 57 to connect inner frame 1 52 and inner frame 2 54, when the positions of inner frame 1 52 and inner frame 2 54 change, transmission channel 1 56 and transmission channel 2 57 can change their extension and retraction length according to their position. It should be noted that although transmission channel 1 56 and transmission channel 2 57 are in a socketed state, they are also sealed to a certain extent because their contact surfaces are tightly fitted, so air leakage is not likely to occur.

[0046] like Figure 7 As shown, the discharge port 58 is located at the end of the outer frame 51 away from the transmission channel 56, the corresponding air inlet 21 is connected to the corresponding outer frame 53, and the air inlet 21 and the transmission channel 57 are respectively close to the two ends of the outer frame 53.

[0047] The gas moving inward from the air inlet 21 moves in a "C" shape along the frame-shaped heat dissipation section 5 and is then discharged from the outlet 58.

[0048] Specifically, the frame-type heat dissipation part 5 is C-shaped, with an air inlet 21 and an exhaust hole 58 at both ends. When the airflow moves, it moves in a C-shape to carry away the heat.

[0049] like Figure 3 and Figure 4 As shown, multiple sets of mounting holes 22 are provided on the inner walls of the sides of both housing 1 and housing 2. Both inner walls of housing 1 and housing 2 are provided with outer limiting layers 59. The outer end of the outer limiting layer 59 has a mounting shaft 591. The mounting shaft 591 is inserted into the corresponding mounting hole 22. The outer limiting layer 59 is used to limit the longitudinal direction of the frame-type heat dissipation part 5.

[0050] Each outer limiting layer 59 is used to clamp the inner frame 1 52 and inner frame 2 54 at the corresponding positions, so that the inner frame 1 52 and inner frame 2 54 can only slide in the longitudinal direction, further limiting the inner frame 1 52 and inner frame 2 54. It should also be noted that the transmission channel 1 56 and transmission channel 2 57 are located inside the outer limiting layer 59, so that when the inner frame 1 52 and inner frame 2 54 clamp the battery, the edge of the battery will not come into contact with the transmission channel 1 56 and transmission channel 2 57.

[0051] like Figure 4 and Figure 5As shown, the outer limiting layer 59 inside the housing 1 and housing 2 respectively clamps the inner frame 1 52 and the inner frame 2 54, ensuring that the inner frame 1 52 and the inner frame 2 54 slide along the outer limiting layer 59.

[0052] like Figure 4 and Figure 5 As shown, elastic elements 55 are fixed inside both inner frame 1 52 and inner frame 2 54. The elastic elements 55 inside inner frame 1 52 and inner frame 2 54 abut against the inner walls of shell 1 and shell 2 respectively. The elastic elements 55 are springs.

[0053] Specifically, elastic members 55 are fixed to the inner sides of both inner frame 1 52 and inner frame 2 54. The function of the elastic members 55 is to support inner frame 1 52 and inner frame 2 54. It should be noted that when the battery is clamped between inner frame 1 52 and inner frame 2 54, inner frame 1 52 and inner frame 2 54 can be pressed against the battery surface to minimize the gap and ensure effective heat transfer. In addition, it should be noted that when the battery surface has uneven surfaces, inner frame 1 52 and inner frame 2 54 at different positions can support the uneven surfaces of the battery, maximizing the contact area and improving heat transfer efficiency.

[0054] like Figure 5 As shown, heat dissipation fins 6 are fixed inside both inner frame 1 52 and inner frame 2 54. When the airflow moves, the heat generated by the heat dissipation fins 6 is quickly transferred to achieve rapid cooling. It should be noted that even if there is dust in the airflow and it adheres to the heat dissipation fins 6, the large number of heat dissipation fins 6 can still achieve good heat dissipation.

[0055] Working principle: The cooling fan 4 on the air collection cover 3 operates, generating airflow into the air collection cover 3, and causing the gas to move from the air inlet 21 into the housing 2. Figure 7 As indicated by the arrows, after the gas enters the outer frame 53 and inner frame 54, it moves along the extending direction of the outer frame 53 and inner frame 54. Then, it passes through the second transmission channel 57 and the first transmission channel 56, enters the outer frame 51 and inner frame 52, and then moves along the extending direction of the outer frame 51 and inner frame 52, finally exiting from the discharge hole 58. It should be noted that the battery is clamped between the inner frame 52 and inner frame 54. The heat generated by the battery is transferred to the inner frame 52 and inner frame 54, and then dissipated by the gas flow. It is important to understand that when the gas moves along the frame-shaped heat dissipation part 5, it does not come into direct contact with the battery, avoiding contact between dust and the battery, thereby improving safety.

[0056] Secondly, through the action of the elastic element 55, the inner frame 1 52 and the inner frame 2 54 can expand and contract, allowing them to directly and closely contact batteries of different sizes, thus improving heat conduction. It should be noted that if the batteries have different height differences, multiple sets of frame-type heat dissipation parts 5 can be set to contact batteries of different height differences, increasing the contact area and enhancing heat dissipation.

[0057] Heat dissipation fins 6 are provided in the inner frame 1 52 and the inner frame 2 54. The heat dissipation fins 6 increase the contact area with the airflow and improve the cooling effect.
