5results about How to "Reduce heat exchange efficiency" patented technology

The application discloses a kind of polyethylene outer protective tube extrusion after cooling setting processing mechanism, its technical scheme includes: cooling box and setting box, the cooling box one side is equipped with setting box, the cooling box inside side away from setting box is equipped with cooling chamber A by partition, the cooling box inside side close to cooling chamber A is equipped with cooling chamber B by partition, the cooling box inside side close to cooling chamber B is equipped with cooling chamber C.A kind of polyethylene outer protective tube extrusion after cooling setting processing mechanism solves the polyethylene outer protective tube in cooling, more using the way of whole section cooling, leading to cooling water and pipe material long time large area contact, heat exchange efficiency is low, the cooling load of equipment is relatively larger, the cooling efficiency of polyethylene outer protective tube is lower, to extend the cooling cycle of single pipe material, seriously influence the production efficiency of polyethylene outer protective tube problem, improve the cooling efficiency of polyethylene outer protective tube, to improve the production efficiency of polyethylene outer protective tube.

The utility model discloses a kind of for facilities agricultural glass greenhouse's entrance hall mounting structure, comprising: big shed main body, entrance hall group and wind shower group;Entrance hall group includes the first entrance hall and the second entrance hall of adjacent arrangement;Second entrance hall is installed at the entrance of big shed main body;Wind shower group is installed in the first entrance hall. The setting of double entrance hall, through the adjacent structure of first entrance hall outside buffer, second entrance hall inside transition, forms the transition of outside environment→first buffer cavity→second buffer cavity→greenhouse interior, makes hot air direct convection, makes door area heat exchange efficiency reduce, the setting of three-stage switch door, first switch door controls outside, second switch door separates buffer cavity, third switch door is connected greenhouse, progressive opening and closing logic, further avoid the defect of door leakage heat.

The utility model discloses a liquid cooling heat pipe radiator, include: radiator main part, including liquid cooling board, heat pipe, radiating fin, heat dissipation frame and fan, the heat pipe is located the bottom of liquid cooling board, the radiating fin is located the outside of heat pipe, the middle part of liquid cooling board is connected with liquid delivery tube, and the both ends of liquid delivery tube are connected with water inlet pipe and water outlet pipe respectively, the middle part of water outlet pipe is provided with the pump body, cleaning assembly sets up in the middle part of heat dissipation frame and fan, including the support frame of fixed heat dissipation frame upper end, can solve in the long -term operation process of fan, external dust will be attached to the surface of radiating fin with airflow, forms the dense dust layer, thereby makes dust accumulation to hinder the direct contact of radiating fin and air, reduces the heat exchange efficiency, then, liquid cooling system is the problem that needs to improve fan speed or prolongs the working time for the compensation heat dissipation efficiency reduction, and then aggravates dust adsorption and increases the energy consumption.

The utility model discloses a purpose lies in providing a kind of composite light water meter box with high protection, can substantially reduce the heat exchange efficiency of inside and outside of box, let water meter device work in the temperature state of more constant, avoid more precise or can realize multiple function water meter product when working in harsh environment appear detection error or cause damage. The composite light water meter box includes water meter box, and the accommodation cavity for installing and fixing water meter is formed in the water meter box;The front side of the water meter box is provided with movable open-close door;The board piece that surrounds the formation water meter box is internally provided with the heat insulation layer structure capable of reducing the heat exchange efficiency of the accommodation cavity and outside.

This application relates to an evaporator and an air conditioner. The evaporator includes a heat exchange tube and multiple fins. The multiple fins are sequentially arranged along the length of the heat exchange tube. The fins are at least divided into first fins and second fins. The first fin includes at least one fin, and the second fin includes at least one fin. Each fin of the first fin has at least one hydrophobic coating, and each fin of the second fin has at least one hydrophilic coating. At least one second fin is arranged adjacent to the first fin. The hydrophilic coating of the first fin and the hydrophobic coating of the second fin are arranged alternately. The first fin is located at both ends of the heat exchange tube along its length. This application, through the alternating arrangement of the hydrophilic and hydrophobic coatings, makes the evaporator less prone to frost and ice formation, and achieves dual optimization of heat exchange efficiency and drainage performance.
