换热器 ε-NTU 计算器(效能-NTU 法)

按效能-NTU 法(ε-NTU)计算换热器:C*=C_min/C_max(0–1),NTU=U·A/C_min,q_max=C_min·(T_h,in-T_c,in),ε=q_actual/q_max。支持四种构型:顺流 ε=[1-exp(-NTU(1+C*))]/(1+C*);逆流 ε=[1-exp(-NTU(1-C*))]/[1-C*·exp(-NTU(1-C*))],C*=1 时取 NTU/(1+NTU);管壳式 1-2 级 ε=2/[1+C*+√(1+C*²)·(1+exp(-NTU√(1+C*²)))/(1-exp(-NTU√(1+C*²)))];叉流(两侧不混合)ε=1-exp{(NTU^0.22/C*)·[exp(-C*·NTU^0.78)-1]}。C*=0(一侧相变,锅炉/冷凝器)统一取 ε=1-exp(-NTU)。可选填 T_h,in、T_c,in,则反推实际传热速率 q=ε·q_max 及两出口温度。温度仅用于差值:Δ°C=ΔK,°F 差×5/9=ΔK。

列出可用工具

连接到 SSE 端点后,列出已开放的工具:

tools/list
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/list"
}

调用此工具

通过工具 id 调用,参数由其参数表构建:

tools/call
{
  "jsonrpc": "2.0",
  "id": 2,
  "method": "tools/call",
  "params": {
    "name": "heat-exchanger-ntu",
    "arguments": {
  "exchangerType": "counter",
  "hotCapacityRate": 1000,
  "coldCapacityRate": 1500,
  "overallU": 500,
  "area": 10,
  "hotInletTemp": 0,
  "coldInletTemp": 0,
  "tempUnit": "°C",
  "decimalPlaces": 4
}
  }
}
可用逗号分隔的 toolId 在一个会话中串联多个工具,例如 /mcp/sse?toolId=png-to-webp,jpg-to-webp,gif-to-webp(最多 20 个)。
