Description

Technical Field

[0001] This utility model belongs to the technical field of heat dissipation channels for heat sinks, and specifically relates to a heat dissipation channel for a heat sink. Background Technology

[0002] Excessive heat generated inside the fuel cell stack can reduce efficiency and performance, limiting its energy storage and release capabilities. The development of cabinet-type heat sinks can more effectively control temperature, ensuring that the fuel cell stack operates within a suitable temperature range, thereby improving the stack's efficiency and performance. This is particularly critical for renewable energy integration, grid dispatch, and other energy applications.

[0003] Excessive operating temperature will accelerate battery aging and degradation, reducing its lifespan. The presence of a cabinet-type heat sink can maintain a suitable temperature, slow down battery aging, extend the lifespan of the battery stack, and thus reduce system maintenance and replacement costs.

[0004] Currently, to ensure the heat dissipation effect of cabinet-type heat sinks, heat dissipation channels are often installed inside. During daily use, these channels are inevitably subject to vibration. When vibrating, the channels are easily squeezed by the fuel cell stack and come into direct contact with the heat sink. Existing heat dissipation channels do not have corresponding buffering mechanisms. Once the fuel cell stack vibrates, the channels are easily squeezed and deformed, which not only damages the channels but also affects the normal use of the heat sink, reduces its heat dissipation efficiency, and makes it inconvenient to use.

[0005] Therefore, in order to address the aforementioned technical problems, it is necessary to provide a heat dissipation channel for the heat sink. Utility Model Content

[0006] The purpose of this invention is to provide a heat dissipation channel for a heat sink, which solves the problem in the prior art where the heat dissipation channel of the heat sink is deformed by the pressure of the fuel cell stack, which not only easily damages the heat dissipation channel but also affects its normal use.

[0007] To achieve the above objectives, the technical solution provided by an embodiment of this utility model is as follows:

[0008] A heat dissipation channel for a heat sink includes: a heat dissipation channel body, a pair of buffer mechanisms, and a support mechanism;

[0009] The heat dissipation channel body is provided with a heat dissipation box shell on its outer side;

[0010] A pair of buffer mechanisms are connected between the heat dissipation channel body and the heat dissipation box shell. The buffer mechanism includes a buffer chamber, a guide plate is provided on one side of the buffer chamber, and a connecting rod is connected between the guide plate and the heat dissipation channel body.

[0011] The buffer mechanism is equipped with support mechanisms on both sides.

[0012] Furthermore, a guide rod is connected between the pair of buffer chambers, which can provide a track for the guide plate, so that the guide plate can be guided by the guide rod and the sliding of the guide plate is more stable;

[0013] The guide plate has a track groove that matches the guide rod, which facilitates the sliding of the guide plate and makes the sliding of the guide plate smoother.

[0014] The buffer chamber is equipped with a pressure plate that can slide inside the buffer chamber and squeeze the hydraulic oil inside the buffer chamber, so that the hydraulic oil can be injected into the limiting airbag.

[0015] A sealing gasket is connected between the pressure plate and the buffer chamber, which improves the sealing performance of the pressure plate and allows the pressure plate to better squeeze the hydraulic oil.

[0016] Furthermore, a synchronizing rod is connected between the pressure plate and the guide plate, so that the pressure plate and the guide plate are connected, and the sliding of the guide plate can drive the sliding of the pressure plate.

[0017] The synchronizing rod passes through the buffer chamber, and a first bearing connects the synchronizing rod and the buffer chamber, making the sliding of the synchronizing rod smoother and reducing the friction between the synchronizing rod and the buffer chamber.

[0018] Furthermore, the buffer chamber is equipped with a limiting chamber, which can limit the limiting airbag, thereby improving the stability of the limiting airbag and enabling the limiting airbag to better support the heat dissipation channel body.

[0019] The limiting chamber is equipped with a limiting airbag, which can support the heat dissipation channel body by expanding, thereby reducing the damage to the heat dissipation channel body.

[0020] A connecting pipe is provided between the limiting airbag and the buffer chamber, allowing the hydraulic oil in the buffer chamber to enter the limiting airbag and inflate it. The connecting pipe runs through the buffer chamber, the limiting chamber, and the limiting airbag.

[0021] Furthermore, the support mechanism includes a support chamber, which facilitates the sliding of the pressure flow plate and provides balance for the sliding of the pressure flow plate;

[0022] The support chamber is equipped with a pressure flow plate, which can slide under the drive of the second bearing, so that the pressure flow plate pressurizes the hydraulic oil, and the hydraulic oil can buffer the pressure flow plate and reduce the sliding speed of the pressure flow plate.

[0023] A support spring is connected between the pressure flow plate and the heat sink housing, which can buffer the pressure flow plate and rebound it when it slides downward.

[0024] Furthermore, the pressure flow plate is provided with several pressure relief holes to facilitate the flow of hydraulic oil and allow the hydraulic oil to pass through the pressure flow plate.

[0025] The pressure flow plate is connected to the heat dissipation channel body by a connecting support rod, which connects the heat dissipation channel body and the pressure flow plate. When the heat dissipation channel body vibrates, it can be buffered by the pressure flow plate. The connecting support rod is set through the support chamber.

[0026] Furthermore, a second bearing is connected between the connecting support rod and the support chamber, which reduces the friction between the connecting support rod and the support chamber and improves the smoothness of the sliding of the connecting support rod. Hydraulic oil is provided in the support chamber, the buffer chamber and the limiting airbag.

[0027] Compared with the prior art, the present invention has the following advantages:

[0028] This invention improves the buffering effect of the heat dissipation channel inside the heat dissipation box by setting corresponding mechanisms on the heat dissipation channel, reducing the possibility of deformation of the heat dissipation channel. This not only reduces the chance of damage to the heat dissipation channel, but also reduces the impact on the normal use of the heat dissipation box, improves the heat dissipation efficiency of the heat dissipation box, and makes it more convenient to use.
