• How to distinguish the quality of liquid cold plate?

  Liquid cold plate has been relatively popular, for the use of manufacturers, the quality of the water cooling plate can make an objective judgment is to improve the quality of equipment necessary ability. Now let Lori the customized liquid cold plate manufacturer to introduce to you, how to distinguish the quality of cold plate good or bad?

   

  1. Appearance.

   

  A product is like a person, a product is like a character. Clothing reflects your taste and attitude towards life. So does the product's appearance. Basic requirements: uniform chamfer, no burr, comfortable feel, roughness shall not be greater than 6.3 (generally 3.2 for Lori), no oil residue on the surface, no oxidation and discoloration.

   

  2. Material.

   

  In the fierce market competition, in order to reduce costs, some businesses use non-national standard materials for the base plate of liquid cold plate. The base plate of cold plate. is generally aluminum plate, some are made from waste aluminum recasting, which will have impurities sand holes, if used in the air cooling heat sink, the risk is not big, but if used in the water cooling plates, there will be the risk of leakage corrosion. For a liquid cooling plate, the use of non-national standard materials can be hundreds to thousands of yuan, which is why the market price difference of different merchants is an important factor.The source and material reports can be confirmed with SGS reports.

   

  3. Process details

  The material can be the same but the process is different, the effect of the  liquid cold plate is completely different, look at the process from these aspects.

  (1) . Dimensional accuracy: the accuracy of hole position is generally about 0.1mm with good consistency.
  (2). Chamfering method. For an excellent manufacturer, chamfering must be done on the machine to ensure uniformity and consistency.

  (3) Look at the deformation amount, especially the flatness of the installation area of core components. Generally, it shall be within 0.1mm in any 100*100mm area, and 0.02mm in those with high requirements.The higher the flatness, the higher the heat transfer efficiency. You can put it on a flat surface with a square ruler and use a feeler to see how big the gaps are.

   

  4. The process of channel formation

   

  Because for liquid cold plate buried copper pipe, copper and aluminum plate through the process of buried pipe connect together, and then by grinding or fly the process for processing, makes the whole piece of water cooled surface to form a smooth surface, whether quality can also be observed from this plane flat, copper and aluminum have fused into a plane, have crack or uneven will affect the heat transfer effect, at the same time, if the joint use the soldering welding, time is long joint leakage is likely to happen, this belongs to the fake inferior products.

  5. The packing and shipping。

   

  As the core component of the equipment, water cooling plate is of high quality and high cost.In addition to surface protection, high quality water cooling plate will pay attention to the protection of the channel, generally using a special cover to protect the channel, prevent dust and other foreign matter into the channel. At the same time, for transport packaging, should use wooden case. 
  

  Finally, most importantly, the liquid cold plate must not have leakage and the risk of leakage. Each product must be tested for leakage and also for bursting pressure. For brazing liquid cooling plate due to many welding leakage points, the cavity area may be very large, especially in the case of thin wall.

• solar geyser suppliers in chian
  pressurised solar geyser suppliers and other solar power products.usually, the solar geyser port elizabeth domestic machine is a thermosyphon system, because of this that the intermittent fountain is placed on a solar collector and the water flow into evidently with out the need for a pump.

  This gets rid of the chance of failure of mechanical parts. For clients who do now not need to have a fountain (water tank) installed on the roof, the fountain may be mounted at the ceiling, because there's sufficient vertical space available to make the relaxation springs above the collector.

  this is referred to as the break up thermosyphon solar water heater. If neither of these two alternatives is possible, install a small electric pump to make the water flow into via the system.

• what is spunlace nonwoven fabric

  what is spunlace nonwoven fabric

  A nonwoven product derived from the process of entangling a web of loose fibers through multiple rows of jets of water at high pressure, this process entangles the fabrics and interlinks the fibres. Interlinking two fabrics in different directions gives it isotropic properties, the same strength in any direction.

  CHARACTERISTICS:

  1. Flexible entanglement, does not affect the original characteristics of the fiber, does not damage the fiber.
  2. Appearance is closer to traditional textiles than other nonwovens.
  3. High strength, low fluffy.
  4. High moisture absorption, rapid moisture absorption.
  5. Good ventilation.
  6. Soft, good shape
  7. Various of Patterns
  8. No adhesive reinforcement, washable

  USES:

  • First of all, spunlace non woven fabric is mainly used for wipes: such as home, personal, beauty, industrial, medical wipes, etc.
  • Too many Wipes both dry and wet are made by spunlace fabric.
  • Second, medical using is another major market for spun lace fabric: such as disposable surgical clothing, surgical cover cloth, surgical tablecloths, surgical aprons, etc;
  • And also wound application materials: bandages, gauze, Band-Aid, etc.
  • Third, spunlace fabric can make for clothes, for example clothing lining, baby clothes, training clothes, carnival night disposable color service, all kinds of protective clothing etc.

• How to design volleyball court lighting?
  Volleyball is one of the ball sports. The stadium is rectangular, with high nets in between. The two sides of the game (six people per party) each occupy one side of the course. The players use the ball to hit the ball from the Internet. The ball used in volleyball is made of sheepskin or artificial leather, rubber is bold, and the size is similar to football.

  Perhaps the strength of the Chinese men's volleyball team can only be in the middle of the world, but the strength of the women's volleyball team is absolutely second to none. At the 2016 Rio Olympic Games, the women's volleyball team won the championship and the Chinese fans were ecstatic! The "women's volleyball spirit" is an example for us to learn. As one of the three major balls, volleyball has a large number of people participating in the country, and there are many strong universities and colleges. The community leagues are numerous and the rankings are becoming part of our lives.

  Volleyball is flying in multiple directions and at multiple angles in the air. The athletes who play are also multi-angle, multi-directional, and move at different speeds. The human eye and volleyball are always a process of tracking and focusing imaging. The player's playing process is the process of tracking the trajectory of the sphere and the positioning of the air.

  According to the characteristics of the indoor volleyball court lighting, the lighting quality objectives of the indoor volleyball hall are as follows: the overall lighting of the stadium is as white as it is. The light color is pure white, the color is pure, bright and clear. The lighting is stable, smooth, non-fluctuating, and there is no stroboscopic effect hazard; the volleyball field lighting fixtures do not produce glare, no glare damage, the venue lighting is not dazzling, not dazzling, not glaring, not dazzling.

  Ensure that the volleyball flight path in the air is real, no tailing, no ghosting, and the air positioning is true and accurate. The athlete's ball is played correctly, played stably, and is visually comfortable and not fatigued.
