3results about How to "Avoid heat accumulation" patented technology

The utility model discloses a cooling and fresh-keeping device for zongzi production, and relates to the technical field of food fresh-keeping. The device comprises a support frame; the mounting seat is rotationally mounted on the supporting frame through a rotating seat, and the mounting seat is driven by a driving component to rotate; and the rotary drum comprises an inner-layer drum and an outer-layer drum which are coaxially arranged, and the inner-layer drum and the outer-layer drum are both of hollow structures. According to the utility model, the driving component drives the double-layer hollow rotary drum to rotate, a bidirectional three-dimensional air supply system formed by direct blowing of the center shaft through hole and side blowing of the circumferential spray head is combined, and the through-type ventilation design of the hollow bearing structure is matched, so that the problems of low efficiency of traditional standing cooling and single airflow of rotary equipment are effectively solved; cooperative circulation of outward diffusion of cold air from the center of the rotary drum and horizontal penetration of the side face is achieved, the cooling uniformity inside and outside the zongzi is remarkably improved, center heat accumulation caused by stacking is avoided, and the cooling time is greatly shortened on the premise that food sanitation and safety are guaranteed.

The utility model relates to related technical field of automobile parts provides a kind of for producing automobile parts's die structure, injection mold and injection equipment.Die structure includes first die, second die and 3D printing insert, first die is equipped with first cavity, first die and second die are oppositely movable, second die is equipped with second cavity, first cavity and second cavity are communicated to form die cavity, die cavity is used to form surface cover, 3D printing insert is located in first die, 3D printing insert is formed with functional position and conformal cooling waterway, conformal cooling waterway is arranged with functional position to avoid, conformal cooling waterway is arranged around the shape of 3D printing insert or along the structure trend of elbow area on 3D printing insert for forming surface cover, avoid the structure interference of ejector pin, exhaust insert and conformal cooling waterway, quickly take away the residual heat of product's elbow area, reduce the deformation shrinkage caused by heat residual after demoulding, to improve product forming quality.

The utility model discloses an electric heating block structure, including stainless steel shell, aluminium core and heating pipe, the inside of aluminium core is equipped with the expansion cavity of extending to aluminium core bottom, the stainless steel shell is equipped in aluminium core outside, the outside of aluminium core is provided with at least one recessed cooperation slot, the inside of stainless steel shell is equipped with the convex structure, the convex structure is inserted cooperation slot in. Form the clamping cooperation through setting cooperation slot in aluminium core outer periphery, the convex structure is set in the inner wall of stainless steel shell, and the design of the bottom inside edge compression can effectively prevent the problem that aluminium core appears loose, displacement or drop -out in long -time cold -hot cycle process, improves overall structure stability and service life.
