迄今为止，压铸铝散热器是最具技术含量，最新型的散热器，以其单片重量轻、容水量低、单片散热量巨大和因其对流加辐射的散热方式，在低温供暖的工况下，热衰减相对较小，完全满足节能环保的要求，而日渐成为市场散热器主流。

 

So far, die-casting aluminium radiator is the most technological content. The latest radiator, with its light weight, low water capacity, huge heat dissipation and convective radiation, has become the mainstream of market radiator because of its relatively small thermal attenuation under low temperature heating conditions, which fully meets the requirements of energy saving and environmental protection.

 

 

 

☆使用寿命：

 

Service life:

 

因供暖水质的偏碱性（PH值约在10-12之间），故需在压铸铝散热器内腔增设低碳钢内胆。由于压铸铝散热器的工艺使然，要求低碳钢内胆须满足800吨压铸压力的工艺，因此，该内胆至少要保证壁厚大于2.0mm，方能承受压铸压力。而该内胆的材质不同于普通钢制散热器，多采用Q235的钢材，其年腐蚀速度按照海水腐蚀的0.08mm/年来计算，也会有25年的使用寿命；钢内胆也可考虑使用熔融防腐工艺处理，该寿命可达50年，完全不低于铸铁散热器的使用寿命。

 

Because the heating water quality is alkaline (PH value is about 10-12), it is necessary to add low carbon steel inner liner in the inner cavity of die-casting aluminum radiator. Because of the technology of die-casting aluminium radiator, the inner liner of low carbon steel must meet 800 tons of die-casting pressure. Therefore, the inner liner must be at least 2.0 mm thick to withstand the die-casting pressure. The material of the inner liner is different from that of the ordinary steel radiator. The steel Q235 is mostly used. Its annual corrosion rate is calculated according to 0.08mm/year of seawater corrosion, and it will have a service life of 25 years. The steel inner liner can also be treated by melting anticorrosive technology. The service life of the inner liner can reach 50 years, which is no less than that of the cast iron radiator.

 

 

☆金属热强度：

 

Thermal Strength of Metals:

 

中心矩为600mm的压铸铝双金属散热器的金属热强度高达1.52W/Kg·℃，是铸铁散热器的5倍，单片重量为1.67kg/片左右，容水量为0.26kg/片，水道为低碳钢Q235，散热部件为800吨压力下致密的ADC12铝锭；通体毫无焊点，极大地发挥了每一平方厘米的散热功能；

 

The metal thermal strength of the die-cast aluminum bimetallic radiator with a center moment of 600 mm is as high as 1.52W/Kg. It is five times as high as that of the cast iron radiator. The weight of the single piece is about 1.67kg/sheet, the capacity of water is 0.26kg/sheet, the channel is low carbon steel Q235, and the heat dissipating parts are compact ADC12 ingots under 800 tons of pressure.

 

 

 

☆散热量：

 

Heat dissipation:

 

中心矩为600mm的压铸铝双金属散热器在进回水温度为95-70℃的工况下，该散热量高达为187W/柱，是铸铁散热器的1.4倍，是钢二柱散热器的两倍多；又因其散热方式为对流兼辐射型散热方式，在现行的低温供暖大环境下，该散热器热衰减很小，尤其在55-30℃的进回水工况下，只需增加为数不多的设备数量即可满足设计所需的热负荷；

 

The heat dissipation of the die-cast aluminum bimetallic radiator with a central moment of 600 mm is 187W/column, 1.4 times that of the cast iron radiator and more than twice that of the steel two-column radiator under the working condition of the inlet and outlet water temperature of 95-70 C. Because of its convective and radiative heat dissipation mode, the heat dissipation of the radiator is very small in the current low-temperature heating environment, especially in the water inlet and outlet at 55-30 C. In addition, only a small number of equipment can be added to meet the design heat load.

 

 

 

☆生产工艺：

 

Production process:

 

压铸铝双金属散热器的生产工艺环保节能，因其为大规模自动化工艺，每道工序的人为因素很少，这样既解决了人为不可控的潜在问题，同时也保证了散热器品质的均衡，是技术密集型企业；

 

The production process of die-casting aluminum bimetallic radiator is environmentally friendly and energy-saving. Because it is a large-scale automation process, there are few human factors in each process. This not only solves the potential problem of uncontrollable human activities, but also ensures the balance of radiator quality. It is a technology-intensive enterprise.

 

 

 

☆使用情况：

 

_Use:

 

压铸铝双金属散热器承压能力很高，甚至可以承受4.0MPa左右的爆破压力试验，在工程使用过程中，几乎不用考虑分区采暖的压力问题。又因其外表面丰润饱满，装饰性很强，因此无需暖气罩等额外措施将其遮蔽，这样既极大地利用了散热量，保证了热的舒适性，又因其占用空间小，艺术性强，完全不影响二次装修的效果。

 

Die-casting aluminum bimetallic radiator has high pressure bearing capacity, even can withstand about 4.0 MPa of blasting pressure test. In the process of Engineering use, the pressure problem of zonal heating is hardly considered. Because of its plump surface and strong decoration, it does not need additional measures such as heating hood to cover it, which not only makes great use of heat dissipation, guarantees thermal comfort, but also because of its small occupancy space and strong artistry, completely does not affect the effect of the second decoration.
