  • 1. SRL Heatsink Overview

    1. The finned tube of SRL finned tube radiator adopts the process of winding aluminum fins with steel tube, which is smooth, free of burrs, wrinkle-free and easy to clean. When wet cooling is carried out in heating and air conditioning engineering, it is easy to remove condensed water on the surface of the fins, and it is not easy to form dust and scale in dry heating and other heat exchange occasions.

    2.SRL finned tube radiator is composed of carbon steel frame and steel aluminum fin heat dissipation pipe. The heat dissipation pipe is fixed by frame, with compact structure, good air tightness and convenient installation.

    3.SRL finned tube radiator is composed of steel tube aluminum fin tube bundle, which is divided into two rows and three rows along the airflow direction, with a total of 37 models;

    4. The working heat medium of SRL finned tube radiator can be steam or hot water, steam (≤ 1.6MPa), hot water (≤ 300 ℃).

    5.SRL finned tube radiator has the advantages of good heat transfer performance, high strength, low flow loss, high corrosion resistance, not easy to deform under long-term hot and cold conditions, and long working life.

    6.SRL finned tube radiator is mainly used in the air heating system of hot air heating, air conditioning and drying device. It is the main equipment in hot air device. It is widely used in the heating and ventilation system of large buildings in the current industrial and mining enterprises.

    7.SRL finned tube radiator model description: ① × ②/③

    ①, ②-respectively, the radiator length, width size decimeter

    ③-Number of rows of heat pipe

    For example, 12 × 5/3 means that the surface is 1250mm long and 545mm wide, and consists of 3 rows of heat dissipation pipes.

    2. SRL finned tube radiator features

    1. Compact structure: the use of steel tube aluminum fin tube bundle, close contact, good heat dissipation performance;

    2. Cost saving: the price is much lower than the price of the hot blast stove, and its performance-price ratio is high;

    3. Careful processing: advanced processing technology, strict quality assurance system, strict organization, careful processing;

    4. Easy to install: installation, use, maintenance is simple and convenient, low labor intensity;

    5. High cost performance: SRL heat dissipation finned tube is made of seamless steel tube wound aluminum. Due to the high heat transfer coefficient of aluminum, low contact thermal resistance, high strength, thermal shock and mechanical vibration resistance, good thermal expansion performance, and considerable expansion of heat transfer surface.

    Technical parameters of 3. SRL type radiator

    Table 1. The experimental formula of SRL radiator performance under different working conditions:

    Radiator model heat medium Heat transfer coefficient K value kcal/m² h ℃ Resistance mm water column
    SRLB× A/2 Steam (one gauge) K = 13.1(Vr)0.40 H=0.174（Vr）1.67
    130 ℃ superheated water (flow rate 0.023-0.037) K = 14.2(Vr)0.24 H=0.153（Vr）1.58
    SRLB× A/3 Steam (one gauge) K = 13.0(Vr)0.43 H=0.309（Vr）1.62
    superheated water 130 ℃ (flow rate 0.0154-0.038) K = 12.5(Vr)0.29 H=0.296（Vr）1.58
