Air fryer capable of forming thermal cycle heating through cyclone

The invention discloses an air fryer capable of forming thermal cycle heating through cyclone. The air fryer comprises a windshield cover, a motor assembly, an extractor fan and a rotating air duct unit, wherein the lower part of the windshield cover is opened, and a small hole is formed in the center of the upper part of the windshield cover; the motor assembly is arranged at the upper part of the windshield cover and comprises a motor transmission shaft, and the motor transmission shaft penetrates through the small hole in the center of the upper part of the windshield cover; the extractor fan is arranged in the windshield cover and is connected with the motor transmission shaft; the rotating air duct unit is arranged in the windshield cover, is positioned under the extractor fan and is fixedly connected with the windshield cover through a connecting post, a ventilating opening is formed in the upper part of the rotating air duct unit, and the lower part of the rotating air duct unit is opened; the rotating air duct unit can enable air flowing downwards under the combined action of the extractor fan and the windshield cover to flow downwards rotationally along a certain angle to form the cyclone. According to the air fryer disclosed by the invention, the thermal cycle heating is formed through the cyclone, and thus food can be more uniformly baked by hot air.

Continous flow thermal device

The present invention provides a thermal cycling device including: a heat exchanger body (3) having a longitudinal axis and longitudinally divided to provide at least two segments which are able to be heated to different temperatures so that said body has peripheral surfaces of different temperatures; a conduit (2) extending about said body so as to be in thermal contact with said peripheral surfaces; a first delivery device to deliver a first fluid to said conduit to cause said fluid to pass therealong and therefore change in temperature as the fluid passes said segments; and a second delivery device to deliver a second fluid to said conduit so as to flow with said first liquid and therefore also change in temperature. The fluid then leaves the device by conduit (4). The invention also is directed to an injector means for use in the thermal cycling device of this invention, comprising: a septum (26); a needle (20) which is able to pierce the septum; a reservoir (27) in fluid contact with septum (26) having an inlet (28) and an outlet (30); wherein when in use, the needle is urged through the fluid in said reservoir and then through the septum while continually purging the reservoir with said purge fluid. The present invention also includes a scanning detector (5) fitted to the outside of the heat exchange body (3) which monitors the course of reaction inside the conduit (2).

Halogen-free fire-retardant high heat conducting insulating resin composition and heat dissipation metal-base copper clad plate

The invention discloses a halogen-free fire-retardant high heat conducting insulating resin composition and a heat dissipation metal-base copper clad plate (CCL). The composition comprises the following components in parts by weight: 10-45 parts of halogen-free epoxy resin, 0-15 parts of thermoplastic resin and/or synthetic rubber, 0.1-5 parts of curing agent, 0.02-1 parts of accelerator, 0.5-1 parts of antioxidant and 25-80 parts of heat conducting filler. The halogen-free fire-retardant high heat conducting insulating resin composition of the invention adopts high heat conducting filler, and the cured composition shows good thermal conductivity, electric insulativity and welding heat resistance as well as high adhesive force. The invention also discloses a heat dissipation metal-base CCL prepared by using the above halogen-free fire-retardant high heat conducting insulating resin composition, which has high thermal conductivity and high peel strength, does not have the problems of peel-off and deterioration even being subjected to thermal cycle of quick heating and quick cooling, and also has high electrical breakdown resistance, good heat resistance and soldering resistance and the like, and the flame retardant rating of the heat dissipation metal-base CCL reaches UL-94V0.
