Refrigerated van Cars and refrigeration units equipped with insulated structures for van-type transport vehicles for refrigerated transport. Commonly used for transporting frozen food (frozen cars), dairy products (milk transport vehicles), vegetables and fruits (fresh goods transport vehicles), vaccine drugs (vaccine transport vehicles). structure The refrigerated truck consists of the walking part of the special car chassis, and the heat insulation car body (generally composed of polyurethane material, glass steel, color steel plate, stainless steel, etc.), refrigeration unit, cabin temperature recorder and other components. For special requirements vehicles, Such as meat hook car, can be added with meat hooks, waist, aluminum rails, ventilation slots and other options. Key equipment 1. Refrigeration unit: Refrigeration units are divided into non-independent refrigeration units and independent refrigeration units; domestic and imported units. The average model uses an external chiller, and a few micro-refrigerators use a built-in chiller. For refrigerated trucks with lower temperature requirements, the built-in cold plate (function equivalent to the evaporator) can be adopted. The refrigeration unit of the refrigerated truck provides a continuous supply of "cold" equipment for the refrigerated trucks. It is generally installed on the front of the front of the container. It has an air-conditioned shape, but has a stronger cooling capacity than the same volume of air conditioner. Refrigeration units are generally divided into two types, independent units and non-independent units. The difference is that the independent units are completely powered by another unit to maintain the work. The non-independent units are completely powered by the engine of the whole vehicle. Refrigeration work. Generally, the refrigeration unit with different power cooling capacity is selected according to the volume of the refrigerated car body and the temperature requirement of the transported goods. 2. Refrigerated car insulation car The refrigeration unit of the refrigerated truck is used for temperature regulation, and the role of the car is for temperature maintenance. If the refrigeration unit is the provider of energy, then the car is the storage of energy. Among the three major components of the refrigerated truck, the refrigeration unit and the insulation compartment are the most important, and the removal of the chassis can be used as a small insulation and refrigerator. Refrigerated car bodies are generally of the following types: (1) The “sandwich†board-bonding type of piece-and-piece assembly is adopted by domestic large-scale refrigerating truck manufacturers, and the refrigerating truck produced by this technology has high heat insulation performance. (2), injection molding foamed into pieces. (3) The whole skeleton is injected into the foaming type. (4), vacuum adsorption type paste Insulation car body selection generally follows several principles: good insulation performance, light weight and not easy to damage. 3. Positioning management system The refrigerated transport vehicle positioning management system is an open positioning and monitoring platform integrating GPS/temperature detection technology, electronic map and wireless transmission technology. Realize effective tracking and positioning management of refrigerated truck resources, and integrate positioning information with business resources of enterprises. The refrigerated vehicle positioning management system not only provides an efficient and flexible management tool for refrigerating enterprises and field personnel, but also creates a new and efficient scientific model for managing and controlling refrigerated vehicle resources for refrigerated enterprises. Product advantages Advantage 1: Highly safe cab Adopting the popular cage structure in Europe; the safety factor of the cab is higher than other brands in the market; the skin is a high-strength steel plate to ensure the impact resistance of the cab; Advantage 2: Lightweight chassis With the finite element as the platform, the cab and the frame are subjected to force analysis in different road conditions. Through continuous optimization, the plate thickness is increased and decreased, and the parameters of the key parts are changed, which not only satisfies the overall strength and rigidity requirements of the chassis, but also reduces the self-weight; Advantage three: system optimization configuration The special chassis of the Lingma H3 high-pressure cleaning car adopts the mainstream Yuchai YC6J series engine, and the Fast 8 gearbox is economical and practical, with good reliability and high cost performance. Advantage 4: The refrigerated truck category is Class F. When the ambient temperature is 30 degrees, the average temperature in the cabin can be kept at minus 20 degrees, which can meet the transportation of most perishable foods. Valin special car chassis Lingma H3 recommended configuration Vehicle parameters: (This article is from Star Horse) With the rapid development of science and technology, the use of plastics in modern medicine is steadily increasing. Medical devices made from injection-molded plastics help reduce health care costs, infectious diseases and pain management. High-tech polymers are used in medical device prototyping and are often used to create improved prosthetics and devices to reduce the risk of infection. Medical plastic injection molding directly improves patient safety and the ability to save more lives. High-gloss injection molding: the basic process of high-gloss injection molding is to rapidly heat the surface of the mold with high temperature and high pressure steam before injection molding, so that the surface temperature of the molding mold cavity reaches above the glass transfer temperature (TG) of the resin plastic, and then inject the plasticized plastic melt into the closed mold cavity. During the injection phase, the mold temperature is kept constant by high temperature and high pressure steam. After injection molding, stop the air supply, blow out the steam in the tube with the air pressure of the duct, and then inject cooling water to make the mold temperature drop rapidly, until the mold is cooled and opened to take out the product.
