Technical Field

The utility model belongs to the technical field of internal structures of batteries, and particularly relates to a thermal management unit of a marine battery.

Background

Generally, the battery pack is directly called a battery in daily life. The structural composition of the battery pack can be mainly divided into the following 4 parts: battery cluster, shell, control module and thermal management unit.

The battery clusters are a plurality of battery cores which are integrally connected, and the control module is connected with the battery clusters and the thermal management unit, so that the charge and discharge actions and the heating and cooling actions can be performed as required. The heat management unit can be divided into water cooling and air cooling according to different principles, and the main structure of the heat management unit is a fan.

On the other hand, the marine battery is most different from the normal battery in that: in the thermal management unit of the marine battery, whether the air inlet or the air outlet, the thermal management unit must have enough waterproof performance in a specific period. Otherwise, water is fed into the shell, the battery cluster and the control module meet water, and the whole battery pack is very easy to discard completely.

Therefore, the thermal management unit of the marine battery has at least one controllable opening waterproof function.

The waterproof device in the patent of the utility model has the following structural principle and advantages: the setting of first heat dissipation bar hole can strengthen the radiating effect of box, and when raining or meet water environment and use down, can drive first dwang and first baffle through the rotation motor to make first baffle cover first heat dissipation bar hole, and then play waterproof effect.

However, the waterproof device has at least the following 2 defects in the actual use process, in other words, the technical problem to be solved by the utility model is that:

1. after the first waterproof component and the second waterproof component trigger the waterproof function, the whole lithium battery is totally closed, so that the lithium battery cannot be used normally, and the blocking type waterproof function is not applicable when the water stroke is relatively light or the lithium battery still needs to be used;

2. the triggering and maintaining of the waterproof function of the lithium battery require the intervention and maintenance of a rotating motor respectively, which is relatively troublesome, and further, the structural complexity of the lithium battery is greatly improved, and at least one motor is additionally arranged.

Therefore, in view of the foregoing, there is an urgent need for a new thermal management unit that has sufficient waterproof strength, a relatively simple waterproof structure, and a battery that can still be used when the waterproof function is triggered, so as to be used on a marine battery.

Detailed Description

The following description is of the preferred embodiments of the utility model and is not intended to limit the scope of the utility model.

As shown in fig. 1-5, a thermal management unit for a marine battery structurally comprises an air inlet pipe 11 arranged on the side surface of a shell a, an air outlet pipe 12 arranged on the side surface of the shell a, a fan 13 arranged in the air outlet pipe 12, a clamping frame unit 1 arranged on the upper surface of the shell a and covering a control module b, and 2 opening box units 2 arranged on the clamping frame unit 1 and respectively connected with the air inlet pipe 11 and the air outlet pipe 12 in an inserting mode after being taken down so as to increase the height of an air inlet.

In this embodiment, the casing a is rectangular, and is made of engineering plastics, which are the same as the air inlet pipe 11 and the air outlet pipe 12. In addition, the air inlet pipe 11, the air outlet pipe 12 and the control module b respectively correspond to 1 opening d of the shell, so that the ventilation effect and the wire connection effect are effectively achieved.

Next, the air inlet duct 11 and the air outlet duct 12 are rectangular in shape, which can ensure that the opening box unit 2 is less likely to perform a harmful rotating operation when being mounted and used, as compared with a circular tube.

The fan 13 is arranged on the shell opening d or the air outlet pipe 12 through a mounting frame, and the dust screen 14 is arranged on the air inlet pipe 11 and/or the air outlet pipe 12. In addition, the air inlet pipe 11 can be further provided with an electric heating wire, so that the temperature of the battery cluster c of the marine battery can reach a proper range rapidly when the marine battery is used in winter.

In addition, when the marine battery has no waterproof requirement, the 2 opening box body units 2 are respectively taken down from the air inlet pipe 11 and the air outlet pipe 12 and clamped at the clamping frame body unit 1, so that the 2 opening box body units 2 have enough stable idle states. At this time, the marine battery may be used inside the cabin or the water surface is sufficiently calm.

Finally, when the marine battery has a waterproof requirement, the 2 opening box units 2 are respectively arranged on the air inlet pipe 11 and the air outlet pipe 12, and the marine battery only slightly improves the air cooling resistance at the moment and can still be used normally. The key is that the tuyere is higher in height, and splash splashed when the battery is used on the deck of the ship body is difficult to enter the shell a, so that the battery is ensured to meet the requirement of a relatively frequent water use scene.

The clamping frame unit 1 comprises an inverted U-shaped plate 101 which is arranged on the upper surface of the shell a and is used for pressing down and fixing the open box unit 2.

In this embodiment, the 2 vertical plates of the inverted U-shaped plate 101 are two end connection parts, and the middle transverse plate is an acting part for covering and protecting the control module b and clamping and fixing the open box unit 2.

The clamping frame unit 1 further comprises a protruding plate 102 arranged on the lower surface of the inverted U-shaped plate 101 and used for transversely clamping the open box unit 2.

In this embodiment, the number of the protruding plates 102 is 2 or 3, ensuring that 2 of the open box units 2 are not easily displaced in the long side direction of the above-described intermediate cross plate.

Wherein 2 of said open box units 2 are either all in use or all idle. When the number of the protruding plates 102 is 2, 1 of the open box units 2 is abutted against one of the above-mentioned risers.

During this time, the control module b is always located at one end position below the inverted U-shaped plate 101.

The distance between the lower surface of the inverted U-shaped plate 101 and the upper surface of the control module b is 2-5cm.

In this embodiment, the control module b may have a lead led out from the upper surface, so that the lower surface of the inverted U-shaped plate 101 cannot be excessively close to the upper surface of the control module b, and the distance of 2-5cm needs to be set, so that the normal use of the clamping frame unit 1 is ensured not to interfere with the control module b.

The open box unit 2 includes a rectangular box 201, a mounting opening 202 provided on the rectangular box 201 for inserting the air inlet duct 11 or the air outlet duct 12, and air outlets 203 provided on the rectangular box 201 and respectively located at positions of both sides of the rectangular box 201 with the mounting opening 202.

In this embodiment, the main body of the open box unit 2 is also made of engineering plastic, and the air inlet 203 is used for air inlet and air outlet when the open box unit is installed and used. When the shapes and dimensions of the air inlet pipe 11 and the air outlet pipe 12 are consistent, 2 opening box units 2 can be mixed.

In addition, when the open box unit 2 is in use, the height of the mounting opening 202 is lower than that of the air opening 203, so that a rubber sealing ring is arranged at the mounting opening 202, and the marine battery is relatively difficult to damage by water inflow inside even if the bottom of the marine battery completely enters water.

The open box unit 2 further includes 2 screw hole plates 204 disposed on the outer surface of the rectangular box 201 and located at two sides of the mounting hole 202, respectively, for connecting the air inlet pipe 11 or the air outlet pipe 12.

In this embodiment, screw holes are preset at the positions of the outer pipe orifices of the air inlet pipe 11 and the air outlet pipe 12, so that the disassembly and assembly difficulty of the open box unit 2 is moderate, and the stability is sufficient during installation.

The clamping frame unit 1 further comprises an elastic piece 103 which is arranged on the lower surface of the inverted U-shaped plate 101 and is positioned between the two screw joint hole plates 204 and is used for vertically clamping the cuboid box 201.

In this embodiment, the elastic piece 103 is made of normal rubber, and has a rectangular shape, and the functions thereof are at least 2 of the following:

firstly, the opening box body unit 2 in an idle state is vertically clamped by virtue of self elasticity;

secondly, the long side dimension of the box body unit 2 is larger than the mounting opening 202, the wide side dimension of the box body unit 2 is slightly smaller than the distance between the 2 screw joint hole plates 204, and the box body unit 2 is ensured to be difficult to shift and drop spontaneously after being extruded by means of moderate elasticity, namely, 1 screw joint hole plate 204 needs to pass over the elastic sheet 103 when the box body unit 2 is inserted and taken out.

Up and down, left and right, front and back are all fully fixed when the open box unit 2 is idle, and even if the open box unit is a marine battery, the open box unit 2 may not have waterproof requirements in normal use, so that most of the time of the open box unit 2 may be in an idle state, which is the function of the clamping frame unit 1.

The mounting ports 202 and the air ports 203 are respectively arranged on two symmetrical side plates of the rectangular box 201.

In this embodiment, the installation openings 202 and the air openings 203 are arranged in a vertical direction and a horizontal direction, and the purposes of the left-right separation are mainly 2:

when the first box unit 2 is used, the mounting opening 202 of the first box unit is necessarily oriented to the shell a, and if the mounting opening 202 and the air opening 203 are on the same side, the air opening 203 is also oriented to the shell a, and the air opening is blocked by the shell a or the inverted U-shaped plate 101, so that the air inlet and outlet effect is seriously affected;

secondly, when the open box unit 2 is idle, the mounting opening 202 needs to be upward along with the screw hole plate 204, and the width of the inverted U-shaped plate 101 is smaller than the length of the open box unit 2, at this time, if the mounting opening 202 and the air opening 203 are on the same side, the air opening 203 is also upward, i.e. directly exposed, so that water and ash are easily introduced into the open box unit 2, otherwise, the process is not very ingenious.

The open box body unit 2 further includes a drain hole 205 provided on an end plate of the rectangular box 201 remote from the mounting port 202, and a hole plug 206 provided on the drain hole 205.

In this embodiment, the drain hole 205 is further away from the mounting hole 202, so that when the open box unit 2 is in use, the drain hole 205 is at the highest position, so that the marine battery is relatively difficult to be damaged when water is in contact with the inside even if the lower half part of the marine battery directly enters water.

After the usage of the open tank unit 2 is completed, a small amount of water will inevitably enter therein, at this time, the open tank unit 2 is inverted, the hole plug 206 is removed, that is, the water is discharged, and finally the open tank unit 2 is put back to the clamping frame unit 1 for standby.

The length of the rectangular box 201 is 20-30cm.

In this embodiment, the length of the rectangular box 201 is relatively large, and when the open box unit 2 is in use, the height of the air opening 203 may be higher than that of the clamping frame unit 1, so that most of the water splashed by small scale is difficult to enter the open box unit 2, and therefore various battery structures in the housing a can be fully protected.

The embodiments of the present utility model have been described in detail with reference to the drawings, but the present utility model is not limited to the above embodiments, and various modifications may be made within the knowledge of those skilled in the art without departing from the spirit of the present utility model. These are all non-inventive modifications which are intended to be protected by the patent laws within the scope of the appended claims.
