Description

Technical Field

[0001] The utility model relates to the technical field of temperature control, in particular to an air cooling plate and an electric box with the air cooling plate. Background Art

[0002] Due to the limited molding process, the fins of the air cooling plate on the electric box are usually highly consistent with each other; when the air is passed through the air cooling plate fin flow channel, the fins on the air cooling plate will absorb heat at the same time, thereby cooling the battery cells. However, when the battery cells are actually arranged inside the electric box, the temperature of the side battery cells will be lower than the temperature of the middle battery cells; when the air cooling plate fins absorb heat at the same time, the battery cells inside the electric box cannot be adjusted to dissipate heat, and there is still a temperature difference between the battery cells, resulting in different battery cell temperatures, affecting the consistency of the battery cells.

[0003] In order to reduce the temperature difference of the battery core, the existing technology usually mills steps of different heights on the air-cooling plate fins to reduce the heat absorption area of ​​the air-cooling plate fins and achieve the purpose of balanced heat dissipation of the battery module. However, this method requires machining in dense fin machines, which can easily cause fin deformation and affect the air duct flow between fins; at the same time, it increases the machining cost; during the processing, the air-cooling plate is first milled with fin steps, and then stir friction welding is performed; due to the different strengths of the air-cooling plate aluminum extrusion molds during the stir friction welding process, the stir friction welding process is unstable, which can easily cause the overall deformation of the air-cooling plate.

[0009] The first fin group and the second fin group are distributed at different positions on the mounting base plate, and a distance between adjacent fins of the first fin group is greater than a distance between adjacent fins of the second fin group.

[0010] Furthermore, the temperature control area is provided on both the first fin group and the second fin group.

[0028] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in conjunction with the implementation modes and the accompanying drawings.

[0029] Please refer to Figure 1 and Figure 5 , an air-cooled plate, comprising a mounting base plate 1 for mounting on a device, a heat insulating member 2 and a fin structure 3 located on the mounting base plate 1;

[0030] The fin structure 3 is provided with a temperature control area 4 corresponding to a relatively low temperature position inside the device, and the thermal insulation component 2 covers the fin structure 3 in the temperature control area 4 .

[0031] From the above description, it can be seen that the beneficial effects of the utility model are: providing an air-cooled plate, adding a thermal insulation part 2 to the fin structure 3 in the temperature control area corresponding to the relatively low temperature position inside the equipment on the air-cooled plate, relying on the thermal insulation part 2 to reduce the heat absorption of the fin structure 3 in the temperature control area, reducing the temperature loss at the relatively low temperature position inside the equipment, and reducing the temperature difference between the relatively low temperature position and other relatively high temperature positions inside the equipment. There is no need to perform deformation processing on the fin structure 3, and the temperature difference at different positions inside the equipment is reduced at a low cost, while ensuring the quality of the fins of the air-cooled plate.

[0032] Further, the fin structure 3 includes a first fin group 31 and a second fin group 32;

[0033] The first fin group 31 and the second fin group 32 are distributed at different positions on the mounting base plate 1 , and the distance between adjacent fins of the first fin group 31 is greater than the distance between adjacent fins of the second fin group 32 .

[0034] From the above description, it can be seen that the first fin group 31 and the second fin group 32 with different adjacent fin spacings have different heat absorption effects respectively. The two can be relatively set according to the different temperature changes inside the equipment, so as to promote the temperature consistency at different positions inside the equipment, so that some temperature-sensitive accessories can operate normally.

[0035] Furthermore, the temperature control area 4 is provided on both the first fin group 31 and the second fin group 32 .

[0036] From the above description, it can be seen that the first fin group 31 and the second fin group 32 are both provided with a temperature control area 4. On the basis of adjusting the heat absorption effect by using different fin spacings, the temperature control area 4 is set, that is, the thermal insulation component 2 is used for further regulation, so that the air-cooled plate is more flexible in controlling the temperature inside the equipment and has stronger applicability.

[0037] Furthermore, the thermal insulation member 2 is detachably connected to the fin structure 3 .

[0038] From the above description, it can be seen that the installation of the thermal insulation component 2 is arranged in a detachable form, so as to flexibly change the actual position of the temperature control area 4 on the installation base plate 1 to meet the actual use requirements of the equipment.

[0039] Furthermore, the thermal insulation member 2 is adhesively connected to the fin structure 3 .

[0040] From the above description, it can be seen that the thermal insulation member 2 and the fin structure 3 are connected by gluing, which not only eliminates the need for connecting accessories, but also makes the thermal insulation member 2 and the fin structure 3 fit more closely, thereby improving the thermal insulation effect.

[0041] Furthermore, the thermal insulation member 2 is composed of at least two thermal insulation sheets 7 , and the thermal insulation sheets 7 are covered one by one on the fins of the fin structure 3 in the temperature control area 4 .

[0042] From the above description, it can be seen that the thermal insulation member 2 and the fin structure 3 adopt the same sheet form, and the two correspond one to one, so as to increase the contact area and improve the thermal insulation effect, thereby significantly reducing the heat absorption capacity of the fins.

[0043] In order to solve the above technical problems, another technical solution adopted by the utility model is:

[0044] An electric box with an air cooling plate, comprising an electric box upper cover 5, a battery module 6 and the above-mentioned air cooling plate;

[0045] The battery cell module 6 is arranged on a surface of the mounting base plate 1 away from the fin structure 3 , the electric box upper cover 5 is arranged on the battery cell module 6 , and the electric box upper cover 5 is connected to the mounting base plate 1 .

[0046] From the above description, it can be seen that the beneficial effects of the utility model are: providing an electric box with an air-cooling plate, adding a thermal insulation part 2 to the fin structure 3 in the temperature control area of ​​the air-cooling plate corresponding to the relatively low temperature position inside the electric box, relying on the thermal insulation part 2 to reduce the heat absorption of the fin structure 3 in the temperature control area, reducing the temperature loss at the relatively low temperature position inside the battery cell module 6, and reducing the temperature difference between it and other relatively high temperature positions inside the equipment, without the need to perform deformation processing on the fin structure 3, reducing the temperature difference at different positions inside the battery cell at low cost, and at the same time ensuring the quality of the fins of the air-cooling plate.

[0047] Furthermore, the electrical box upper cover 5 is provided with an air-conditioning air inlet;

[0048] The temperature control area 4 is located on the installation base plate 1 adjacent to the air inlet of the air conditioner.

[0049] From the above description, it can be seen that the temperature loss in the position near the air inlet of the air conditioner in the electric box is rapid. Compared with other positions, the temperature of the battery core near the air inlet of the air conditioner is lower. Therefore, a temperature control area 4 for installing a heat insulating part 2 is provided on the fins of each fin structure 3 to reduce the temperature loss at this location.

[0050] Please refer to Figures 1 to 5 , Embodiment 1 of the present utility model is:

[0051] A wind-cooled plate comprises a mounting base plate 1 for mounting on a device, a heat insulating member 2 and a fin structure 3 located on the mounting base plate; the fin structure 3 is provided with a temperature control area 4 corresponding to a relatively low temperature position inside the device, and the heat insulating member 2 covers the fin structure 3 in the temperature control area 4.

[0052] In this embodiment, the fin structure 3 includes a first fin group 31 and a second fin group 32; the first fin group 31 and the second fin group 32 are distributed at different positions on the mounting base plate 1, and the spacing between adjacent fins of the first fin group 31 is greater than the spacing between adjacent fins of the second fin group 32. The first fin group 31 and the second fin group 32 are both provided with a temperature control area 4.

[0053] Take the case where the air cooling plate is installed on the electrical box as an example. Figures 2 to 4 As shown, the use process of an air cooling plate in this embodiment is as follows:

[0054] Firstly, for the electric box, the temperature of the middle area of ​​the battery cell module 6 of the electric box is higher than that of the surrounding batteries. Therefore, the first fin group 31 with a larger distance between adjacent fins, that is, the heat absorption capacity is relatively weak, is set at a position close to the side of the mounting base 1, which corresponds to the surrounding area of ​​the battery cell module 6; and the first fin group 31 with a smaller distance between adjacent fins, that is, the heat absorption capacity is relatively strong, is set in the middle position of the mounting base 1, which corresponds to the middle area of ​​the battery cell module 6, thereby promoting temperature balance at different positions of the battery cell module 6.

[0055] Secondly, there are some locations in the electric box where the temperature drops rapidly, such as the air inlets of air conditioners, which can easily affect the temperature of the battery cells near these locations. Therefore, temperature control areas are set at the corresponding locations, and the temperature control is achieved by relying on the thermal insulation part 2 to reduce the heat absorption of the fin structure 3.

[0056] Furthermore, it should be noted that the air cooling plate of this embodiment can be used for temperature control not only in electrical boxes but also in other devices whose internal components have higher requirements for the operating environment temperature.

[0057] In this embodiment, the heat insulating member 2 is detachably connected to the fin structure 3. As a preferred mode, the heat insulating member 2 is connected to the fin structure 3 by gluing. In addition, the heat insulating member 2 is composed of at least two heat insulating sheets 7, and the heat insulating sheets 7 are covered one by one on the fins of the fin structure 3 in the temperature control area 4. During installation, glue is applied to the fins of the fin structure 3 and the corresponding positions on the mounting base plate 1, and the heat insulating sheets 7 are glued to the fins.

[0058] Please refer to Figures 2 to 4 , Embodiment 2 of the present utility model is:

[0059] An electric box with an air cooling plate comprises an electric box upper cover 5, a battery module 6 and an air cooling plate of the first embodiment; the battery module 6 is arranged on a side of the mounting base plate 1 away from the fin structure 3, the electric box upper cover 5 is arranged on the battery module 6, and the electric box upper cover 5 is connected to the mounting base plate 1. An air inlet for air conditioning is arranged on the electric box upper cover 5; and the temperature control area 4 is located on the mounting base plate 1 adjacent to the air inlet for air conditioning.

[0060] In summary, the utility model provides an air-cooling plate and an electric box with an air-cooling plate, wherein a heat insulating member is added to the fin structure in the temperature control area of ​​the air-cooling plate corresponding to the relatively low temperature position inside the equipment, and the heat insulating member is relied upon to reduce the heat absorption of the fin structure in the temperature control area, thereby reducing the temperature loss at the relatively low temperature position inside the equipment, and reducing the temperature difference between the relatively low temperature position and other relatively high temperature positions inside the equipment, without the need to perform deformation processing on the fin structure, thereby reducing the temperature difference at different positions inside the equipment at a low cost, and ensuring the quality of the fins of the air-cooling plate, and at the same time providing fin groups with different adjacent fin spacings and correspondingly providing a plurality of temperature control areas, so as to flexibly adjust the temperature changes inside the equipment.
