Abstract: An immersion cooling system includes a cooling tank, a housing and a valve. The coolant tank is configured to accommodate a liquid coolant and an electronic device immersed in the liquid coolant. The housing covers a side of the cooling tank and thereby forms an enclosure. The valve has two ports, one of which communicates with the enclosure and the other communicates with a part of the cooling tank above the liquid coolant. The valve is configured to open in response to a gas pressure inside the cooling tank exceeding an upper limit.

Abstract: A heat pipe comprises a flat tube and a wick structure. The flat tube includes a hollow chamber and has a front and a rear sealed ends along an axial direction. The wick structure is disposed in the hollow chamber and extended along the axial direction of the flat tube. The wick structure is divided into a front, a middle and a rear sections sequentially along the axial direction. The front section is near the front sealed end, the rear section is near the rear sealed end. The front, middle and rear sections have a maximum length parallel to the width direction, respectively. The maximum length of the front section is greater than that of the middle section, and the maximum length of the middle section is greater than that of the rear section.

The air cylinder assembly comprises a mount, a back plate, at least one air cylinder positioned between the mount and the back plate. The first plate assembly further includes a linear servo motor for linearly moving the air cylinder assembly with respect to the first base, and a first tooling plate with a sealing surface area. The first tooling plate coupled to the back plate.

Abstract: A converter includes a chopper circuit, including a first resistor and a power switch connected in series; a current detection circuit, including: a first capacitor and an isolation circuit, where an input end of the isolation circuit is connected in series with the first capacitor, an input end of the current detection circuit is connected in parallel to one of the first resistor or the power switch, and the current detection circuit detects a direction of a current flowing through the first capacitor and outputs a current detection signal; a signal conditioning circuit, electrically connected to an output end of the current detection circuit, receiving the current detection signal and outputting a chopper circuit operating state signal; and a controller, electrically connected to the signal conditioning circuit, receiving the chopper circuit operating state signal and determining whether the chopper circuit is in a turned-on state or a turned-off state.

Abstract: A cable strain relief structure includes a conducting seat, a cable, a supporting element, and an insulating sleeve. The conducting seat includes an insulating body and a conducting element disposed in the insulating body. The cable passes through the insulating body and is electrically connected to the conducting element. The supporting element includes a plurality of ridges arranged spacedly and annularly on the outer periphery of the cable. The ridges are extended in the direction along the cable and away from the insulating body. The insulating sleeve covers the supporting element and is extended in the direction along the cable.

Abstract: The present application provides a biological active peptide from seawater pearl, the sequence of which is Ile-Pro-Ser-Thr-Thr-Pro-Phe-Pro-Ser-Thr-Thr-Val-Ala-Thr-Thr-Thr-Met, and the name of which is SCOL polypeptide. The biological active peptide can improve an ACE2 enzyme activity to 3.76 times, and can be applied in preparation of a drug improving an ACE2 activity, treating hypertension, anti-heart failure, anti-tissue fibrosis, anti-inflammation, and type 2 diabetes mellitus and the complication thereof, and relieving neuropathic pain. The biological active peptide can be specifically bound to the ACE2, effectively inhibits the 65% binding between novel coronavirus S protein and the ACE2, can be applied in preparation of an anti-coronavirus infection drug as an inhibitor, and specifically applied in preparation of anti-novel coronavirus drug.

Abstract: A stator structure includes a silicon steel sheet, a first plastic material and a second plastic material. The silicon steel sheet has a plurality of pole faces. The first plastic material covers on the silicon steel sheet. The second plastic material forming on the first plastic material. The first plastic material covered on the plurality of the pole faces is not covered by the second plastic material. The thermal conductivity of the first plastic material is higher than that of the second plastic material.

Abstract: A lithium battery cell includes an upper cover module, a first battery electrode group, a second battery electrode group, and a plurality of first electrode connection straps. The first electrode connection straps are stacked together and have the same width and length. A first end of the first electrode connection straps is welded to a first tab, a second end of the first electrode connection straps is welded to a second tab, and a middle part of the first electrode connection straps is welded to a first electrode terminal. An even number of first bending parts are formed between the middle part and the first end, and an even number of second bending parts are formed between the middle part and the second end, and the first bending parts and the second bending parts are symmetrical to each other. Furthermore, a lithium battery cell manufacturing method is also disclosed therein.
