The invention discloses a burner of an inner flame gas stove, which consists of a burner body and a fire distributer device; an upper layer fire hole and a lower layer fire hole are arranged on the fire distributer device and the direction of the outlets of the fire holes is inward, and an air channel is arranged or not arranged between the upper layer fire hole and the lower layer fire hole; a single inner cavity or two independent inner cavities is or are arranged; the two independent inner cavities are arranged so that the flame at the upper layer and the lower layer can be regulated independently; while the air channel is arranged so that the air supplementation can be more abundant. The burner utilizes multiple-layer fire holes, stratified combustion and multiple-layer cyclonic flame, and has the advantages of large heat flow, fierce fire power, high heat efficiency, low-CO and low-NOx in smoke gas, no fire hole blocking and the like.

A piston rod for piston compressors, wherein the piston rod has a base body with one end facing the piston, one end away from the piston, and at least one cavity. The cavity is filled with a solid, whose specific thermal conductivity is greater than that of the base body.Furthermore, the invention concerns a piston compressor with a piston and a nonlubricated piston rod seal, wherein the piston is connected to the described piston rod.

A method for removing vapor within a heat pipe includes providing a predetermined amount of working fluid injected into the heat pipe. An opening is reserved at one end of the heat pipe. The opening is communicated with a vacuum environment. The communication between the opening and the vacuum environment is normally disconnected, such that at the instant the communication is connected ,the vacuum level of the vacuum environment is maintained at a certain range. The communication between the opening of the heat pipe and the vacuum environment is intermittently connected for several times. Within the duration while the communication between the opening and the vacuum environment is connected, the working fluid is evaporated without being boiled and vapor is exhausted from the opening.

A bearing ring with integrated cooling channels and a method for producing a bearing ring with integrated cooling channels are provided.

The invention discloses a radiator of an infrared radiation gas stove. The radiator comprises a ceramic base plate (1), wherein a plurality of fire outlet holes (11) are formed in the base plate (1). The radiator is characterized by also comprising burners (2), wherein connecting holes (12) are formed in the base plate (1); the connecting holes (12) and the fire outlet holes (11) are formed at intervals in a staggered mode; the burners (2) are inserted into the connecting holes (12) and are protruded out of the upper surface of the base plate (1). The burners form an uneven concave-convex structure, so that the effective radiation area is increased, and the radiation strength is effectively improved.

A soya-bean milk machine includes a barrel body and a heating element. The heating element is arranged at bottom and / or side wall of the barrel body and / or in the barrel body, a super heat conductor is arranged on a heating surface of the heating element or close to the heating element, and is used for heating slurries in the barrel body, the heating element is a heating disc and is arranged at outer bottom of the barrel body, and the super heat conductor is arranged between the heating disc and the barrel body. The super heat conductor includes a casing with cannular shape, discal shape, annular shape or groove-type shape, a vacuum cavity is arranged in the casing, working medium is disposed in the vacuum cavity, lower segment of the vacuum cavity is evaporation segment and is arranged at or close to the heating surface of the heating element, and upper segment of the vacuum cavity is condenser segment and is arranged at bottom and / or side wall of the barrel body and / or in the barrelbody. When using the heating element to heat, the soya-bean milk machine forms a real stereo encircling heating for the bottom of the barrel body by utilizing efficient heat-conducting characteristicof the super heat conductor (thermal resistance is close to zero). The soya-bean milk machine has simple and reasonable structure, large heat flow and large heating area, and can save a large amount of metal material compared with other heating mode.

The invention relates to an efficient heat exchange fin. The efficient heat exchange fin comprises a base plate. The surface of the base plate is provided with at least two heat exchange pipe holes at intervals and provided with at least two flow disturbing rings at intervals. The efficient heat exchange fin is characterized in that the heat exchange pipe holes are arranged in two rows, the upper row of heat exchange pipe holes and the lower row of heat exchange pipe holes are staggered, the flow disturbing rings are also arranged in two rows, the upper row of flow disturbing rings and the lower row of flow disturbing rings are staggered, each flow disturbing ring is located above the corresponding heat exchange pipe hole, the two side edges of the base plate are each provided with a turnup protruding outwards, the portion, located between the two rows of flow disturbing rings, of each turnup is recessed inwards, so that an energy gathering arc is formed, the portions, corresponding to the energy gathering arcs, of the surface of the base plate are provided with flow guide channels, the flow guide channels are located between the upper flow disturbing rings and the lower flow disturbing rings, a first end opening of each flow guide channel faces the lower row of flow disturbing rings, and a second end opening of each flow guide channel faces the upper row of flow disturbing rings. The efficient heat exchange fin can greatly improve the heat exchange intensity and the heat exchange efficiency.
