Description

Technical Field

[0001] The utility model relates to the field of high temperature protection, in particular to an anti-blocking thermal shock buffer device. Background Art

[0002] High temperature protection generally uses energy blocking and temperature buffering to achieve temperature control. In some all-weather conditions, uncertain time, and unknown posture applications, special design methods and principles are required to ensure the maintenance-free and high-reliability function of the thermal buffer device. A typical example is an airborne black box. When the function (thermal buffer) is required to work, its posture (forward, reverse, sideways, etc.) and time are random, while in normal times, it is necessary to maintain zero leakage of the thermal buffer medium and the integrity of the functional structure in an environmental change of -30 to +70°C.

[0003] By placing spherical solid phase change materials in the box, the phase change materials can be vaporized at a specific temperature, break through the pores, and achieve full conversion and capacity release of the temperature buffer medium. However, in the existing thermal buffer device, the solid phase change materials are generally spherical or cylindrical. The solid phase change materials increase in volume during the process of being heated, and the phase change materials are easy to block the pores. As a result, when the insulated equipment reaches the predetermined temperature, the pores are blocked, causing the thermal shock buffer device to fail. For this reason, we propose an anti-blocking thermal shock buffer device to solve the above problem. Utility Model Content

[0004] The utility model provides a heat shock buffer device that is anti-blocking, which solves the problem that the volume of the phase change material increases during the process of being heated, and the phase change material is easy to block the air outlet, resulting in the air outlet being blocked when the insulated equipment reaches a predetermined temperature, causing the heat shock buffer device to fail.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is: an anti-blocking thermal shock buffer device, comprising two outer shells, an anti-blocking device is provided on the outer shells, the anti-blocking device comprises a mounting seat, a fastener and an exhaust member, and an anti-overflow sealing tape is provided on the top of the anti-blocking device;

[0006] The tops of the mounting seat, the fastener and the exhaust member are located in the same plane.

[0007] In a preferred solution, a device limiting groove is provided at the bottom of the outer shell, a connecting groove is provided on one side of the device limiting groove, a heat insulating device is provided between the two outer shells, and the heat insulating device passes through the connecting groove and is installed on the device limiting groove.

[0008] In a preferred solution, an anti-blocking device is provided on the upper cover body, a groove is provided on the upper cover body, a mounting hole is provided on the groove, and an anti-overflow sealing tape is pasted on the top of the mounting hole.

[0009] In a preferred solution, the mounting seat includes an outer ring, a bottom ring is provided at the bottom of the outer ring, a first thread is provided on the inner wall of the outer ring, and the outer ring abuts against the mounting hole.

[0010] In a preferred embodiment, the fastener comprises a hollow cylinder, a second outer ring is provided on the cylinder, a third thread is provided on the outer wall of the second outer ring, a second thread is provided on the inner wall of the cylinder, the second outer ring is connected to the first thread, and a plurality of flat-bottom holes are provided on the cylinder.

[0011] In a preferred solution, the exhaust member comprises a hollow exhaust cylinder, a curved bottom cover is provided at the bottom of the exhaust cylinder, a plurality of layers of circular array exhaust holes are provided on the exhaust cylinder, and an annular baffle is provided on the outer side of each layer of exhaust holes.

[0012] In a preferred solution, a fourth thread is provided on the top of the exhaust pipe, and the fourth thread is connected to the second thread.

[0013] In a preferred solution, a solid phase change material is provided in the outer shell.

[0014] The beneficial effects of the utility model are as follows: a mounting seat is installed on the upper cover body, the exhaust member is inserted from the bottom of the fastener, the exhaust member is rotated so that the fourth thread and the second thread are connected, so that the top of the exhaust member is flush with the top of the fastener, the structure of the fastener and the exhaust member is extended into the air of the bottom ring, and extended into the flat-bottom hole through the two ends of the clamp, and the structure of the fastener and the exhaust member is rotated so that the first thread and the third thread are connected until the fastener is flush with the top of the mounting seat, so that the multiple annular baffles on the exhaust member can pass through the bottom ring, so that the exhaust member can pass through the mounting seat, and at the same time ensure that the overall structure of the anti-blocking device keeps the top level, so as to facilitate the pasting of the anti-overflow sealing tape.

[0015] The exhaust part is provided with an arc-shaped bottom cover at the bottom, and the exhaust hole is located on the side of the exhaust pipe. When the spherical phase change material expands, the phase change material at the bottom of the exhaust part will not block the exhaust hole. The multi-layer annular baffle on the outside of the exhaust pipe will shift to the side of the exhaust pipe during the expansion of the phase change material. The annular baffle can prevent the exhaust hole from directly contacting the phase change material. At the same time, when the heated gaseous phase change material suddenly encounters the colder exhaust part material, if the phase change material suddenly liquefies, the liquid can flow down along the outer wall along the annular baffle, further avoiding the blockage of the exhaust hole and the failure of the overall structure.

[0016] The solid phase change material in the overall device is vaporized to ensure that the temperature buffer medium has reached a saturated state when sealed, thereby solving the sealing problem of the temperature buffer medium of the phase change unit under normal conditions. The corresponding switch can be opened at a specific high temperature to achieve full conversion of the temperature buffer medium and release of its capacity, which has great promotion value.
