Description

Technical Field

[0001] The utility model relates to an air outlet structure of a heat flow meter, in particular to a universal defrosting connection structure of the heat flow meter. Background Art

[0002] Heat flow meters are widely used in 5G communications, semiconductor chips, sensors and other fields. They can detect chemical changes and physical damage caused by high and low temperature thermal shocks in the shortest possible time, reduce testing and verification time, and quickly improve product development and production efficiency;

[0003] However, in the existing heat flow meter structure, the outlet pipe structure has a very low temperature of the inner pipe through which the low-temperature gas passes, which causes this part to be easily frosted, affecting its use. In order to improve its flexibility and expand its usage scenarios and application areas, it is necessary to design a universal defrostable connection structure. Utility Model Content

[0004] The utility model aims to provide a universal defrosting connection structure of a heat flow meter, which can realize the rotation of the air outlet direction and help the air outlet structure to defrost and avoid affecting the air outlet.

[0005] The above technical objectives of the utility model are achieved through the following technical solutions:

[0006] A universal defrostable connection structure for a heat flow meter comprises an air inlet joint, the outer end of which is connected to a fixing seat, a circular groove is provided in the fixing seat and is rotatably connected to a universal rotating ventilation shaft; the outer end of the universal rotating ventilation shaft is connected to an air outlet joint; the outer sleeve of the universal rotating ventilation shaft is provided with a hollow shell, the hollow shell is connected with an air inlet hole and an air outlet hole which are interconnected, and circulating gas is continuously introduced into the hollow shell through the air inlet hole to defrost the universal rotating ventilation shaft.

[0007] By adopting the above technical solution, the air inlet connector is connected to the air outlet connector, and the air outlet connector can be rotated 360° through the universal rotating ventilation shaft, and can also be used in conjunction with a connecting hose to increase the blowing angle range; circulating gas is continuously introduced through the hollow shell to defrost the universal rotating ventilation shaft to prevent it from affecting the air outlet.

[0008] Furthermore, the air inlet of the hollow shell is located at an end away from the air inlet connector, and the air outlet is located at an end close to the air inlet connector.

[0009] By adopting the above technical solution, low-temperature gas is blown from the air inlet joint to the air outlet joint on the universal rotating ventilation shaft, while the circulating gas is blown from the other direction, which helps to improve the heat exchange effect with the universal rotating ventilation shaft.

[0010] Furthermore, the air outlet holes are provided in a plurality.

[0011] By adopting the above technical solution, the heat exchange effect of the inside of the hollow cavity on the universal rotating ventilation shaft is improved.

[0012] Furthermore, the hollow shell includes a flange close to one end of the air inlet connector, and a plurality of air outlet holes are provided on a side of the flange away from the air inlet connector.

[0013] By adopting the above technical solution, the position of the air outlet hole can be easily changed so that air is discharged toward a direction close to the air outlet joint.

[0014] Furthermore, a plurality of air outlet holes are arranged aligned with the outer periphery of the hollow shell.

[0015] By adopting the above technical solution, the exhausted circulating gas can further purge the periphery of the entire device body to prevent frost.

[0016] Furthermore, the hollow shell includes a hollow outer cover and a hollow upper cover, and a hollow cavity is processed at one end of the hollow outer cover away from the air inlet connector and is detachably connected to the hollow upper cover.

[0017] By adopting the above technical solution, the processing and installation of the hollow shell are facilitated.

[0018] Furthermore, the universal rotating ventilation shaft is provided with a limit spring on the outside to limit its axial displacement in the circular groove of the fixing seat.

[0019] By adopting the above technical solution, the axial displacement of the universal rotating ventilation shaft in the circular groove of the fixing seat is limited, thereby preventing the remaining fixing seats from detaching.

[0020] Furthermore, a locking handle is connected to the fixing seat, and the locking handle is locked to the outer periphery of the universal rotating ventilation shaft to lock its position after rotation.

[0021] By adopting the above technical solution, the locking and fixation of the universal rotating ventilation shaft after rotation is achieved.

[0022] Furthermore, the air inlet connector is externally connected to a connecting block, which is detachably connected to a fixing seat. One end of the air inlet connector is for air intake, and the other end penetrates the fixing seat and is inserted into the universal rotating ventilation shaft.

[0023] By adopting the above technical solution, the disassembly of the air intake connector part and the entire device is facilitated, so that the air intake connector can intake air vertically, and when necessary, it can be connected to the fixed seat part to adjust the air outlet position through the universal rotating ventilation shaft part.

[0024] In summary, the utility model has the following beneficial effects:

[0025] By connecting the air inlet connector with the air outlet connector, the air outlet connector can be rotated 360 degrees through the universal rotating ventilation shaft; the temperature of the inner pipeline through which the low-temperature gas passes is very low. In order to effectively defrost, a double-layer hollow structure is adopted, and circulating gas is continuously introduced through the hollow shell, and the low-temperature gas is blown from the air inlet connector to the air outlet connector on the universal rotating ventilation shaft, while the circulating gas is blown from the other direction, so as to improve the heat exchange effect with the universal rotating ventilation shaft, so as to defrost the universal rotating ventilation shaft and avoid it affecting the air outlet; and the air outlet hole is aligned with the outer periphery of the hollow shell, so that the discharged circulating gas can further purge the outer periphery of the entire device body to prevent frost;

[0026] The universal rotating ventilation shaft cooperates with the hole on the fixed seat, and then a retaining spring is used to limit the position, and the locking hand-tightening position is adopted, so that the universal rotating ventilation shaft can rotate in the limiting hole of the fixed seat and will not be disengaged; the connecting block is detachably connected to the fixed seat, which is convenient for the disassembly of the air inlet joint part and the whole device, so that the air inlet joint can be vertically air-intaked, and the fixed seat part can be connected when needed to adjust the air outlet position through the universal rotating ventilation shaft part; it is reliable in practical application, and has a simple structure and a stable locking effect.
