Heat Dissipation Group

The heat dissipation group is an important accessory component of the transformer, mainly used to dissipate the heat generated during the operation of the transformer, ensuring that its temperature remains within a safe range, thereby guaranteeing the stable operation of the transformer and extending its service life. The heat dissipation group is typically composed of heat sinks, fans, oil pumps (for oil-immersed transformers), oil pipes, temperature controllers and other components. Its design and performance directly affect the load capacity and reliability of the transformer.

Product Overview

Key Features and Capabilities

Core product characteristics:

High-efficiency heat dissipation performance: Multi-fin or corrugated heat sink structure enlarges heat dissipation area for higher cooling efficiency. Optional forced air cooling (fans) or oil circulation systems (oil pumps) for high-load working conditions
Corrosion-resistant and high-strength materials: Heat sinks adopt aluminum alloy or stainless steel, anti-corrosion and anti-oxidation for harsh outdoor conditions. Oil pipes and connecting components are anti-rust treated for long-term stable operation, advancing sustainable substation thermal management
Intelligent temperature control system: Built-in temperature sensors and automatic controllers. Fans or oil pumps auto start-stop according to transformer oil temperature or winding temperature, saving energy and reducing mechanical wear

Modular design: Flexible to increase or decrease heat-dissipation units (heat sinks / fan groups) to match transformers of different capacities. Easy installation & maintenance, lower O&M costs

Platform‑level capabilities:

Modular Cooling Architecture: Plug-and-play modules scalable for different transformer sizes and substation layouts, supporting phased deployment and future upgrades without heavy retrofits
High-Efficiency Heat Exchangers: Compact large-surface heat exchangers with low fouling and low pressure drop, boosting heat-transfer performance; suitable for renewable storage cooling to stabilize battery temperature and extend cycle life

Intelligent Thermal Control: Integrated sensors & control logic realize real-time cooling optimization. Dynamically adjust fan speed, coolant flow or heat-sink engagement by temperature, load and ambient data to balance energy consumption and cooling capacity for efficient substation thermal management
Redundant and Fault-Tolerant Design: Redundant pumps, fans and control nodes ensure valid thermal management even under single-component failure or maintenance status for substation safety
Low-Maintenance Materials and Coatings: Anti-corrosion coatings and long-life material selection for outdoor & industrial environments, extending maintenance cycles and stabilizing whole-life-cycle costs

FAQ

Frequently Asked Questions

Q1: Are your transformer accessories (tanks, cores, radiators) suitable for non‑standard transformer models? Do you support customisation based on drawingsA1: Absolutely. We are not only a manufacturer but also a provider of customised solutions. Whether you provide hand‑drawn sketches, used part samples, or PDF drawings, our technical team can produce precise CAD production drawings for you. For cores, we can tailor the stacking scheme of grain‑oriented silicon steel sheets according to your loss requirements; for tanks, we can adjust wall thickness and reinforcement structures based on insulation class

Q2: How do you ensure that the cores or clamping frames you produce match the performance of my original transformer designA2: We implement full‑process quality traceability. For cores, we strictly test flux density and specific loss to ensure they meet or even exceed national standards. For clamping frames (clamps), we pay special attention to punching position accuracy and galvanising/anti‑corrosion treatment, and provide CMM (coordinate measuring machine) inspection reports for critical dimensions, ensuring seamless installation upon receipt

Q3: What materials are used for the transformer tanks and radiators? How do you prevent rustingA3: We conventionally use high‑quality cold‑rolled steel plates (Q235B or Q345R). For rust prevention, we perform strict shot‑blasting to remove mill scale, followed by epoxy coal tar paint or polyurethane topcoat, with a dry film thickness strictly controlled above 120μm. For radiators (fin‑type radiators), we place special emphasis on internal pickling and Phosphating treatment to ensure that the transformer oil is not contaminated during circulation

Q4: Are the silicon steel sheets for the cores imported or domestic? Are the clamping frames strong enoughA4: We offer two options – Baowu Steel and Nippon Steel – to suit different budget requirements. For clamping frames (clamps), we use high‑strength steel formed in one stamping process, followed by vibration ageing treatment to relieve internal stress. This ensures that the clamps do not deform during a transformer short circuit, firmly securing the core
