Description of stainless steel surface cooler
One: explanation:
The stainless steel tube of TL type high efficiency heat transfer system is worn with stainless steel sheet type surface cooling heat exchanger. It adopts advanced mechanical and circular corrugated double flanged stainless steel ribs. The mechanical expansion tube makes the stainless steel tube contact closely with the stainless steel ribs. The circular corrugation can promote the fluid rate flow, destroy the boundary layer and increase the heat transfer coefficient. The advanced structure type, water route, pipe distance and spacing design are reasonable, which makes the heat exchanger have good heat transfer performance, small air resistance, compact structure, light weight and so on. It can be widely used in air conditioning, cooling, dehumidification, heating and other projects. It is an ideal supporting product for fresh air and air conditioning units. It can be used as a cold ice cream or heating alone with the wind pipe. The stainless steel tube is welded by low temperature quick brazing to ensure >1.2Mpa.

Two: the main specifications are:

不锈钢管直径（mm）	孔距（mm）	排距（mm）	翅片规格	片距（mm）
ф15.88	38	33	不锈钢翅片	1.8---4
ф9.52	25	21．6	不锈钢翅片	1．3—4
ф12.7	31.75	27.5	不锈钢翅片	4---9

Three:
The TL type numbering method is: TL x 4 x 24 x 1500 (Z) 2.7
TL - - model
4 - - the number of N
24 -- - the number of surface tubes n
1500 -- - the surface pipe length A
(Z) - the direction of the air flow (Y is right)
2.7 -- - t=2.7
Relevant technical parameters:
Windward area: Fy=A * B (M2) heat transfer area: F=Fd A n n N (M2)
Single pipe per meter heat dissipation area: Fd=0.84m2 (film distance 2.7) total water area: f=1.767 * 0.0001 / N (M2)
Ventilation net face ratio: =Ff / Fy=0.532 (calculated by slice distance 2.7).
Four: selection of material and type of surface cooler
1: the remittance material of the surface cooler can be a galvanized steel pipe, a stainless steel tube or a stainless steel tube, the surface of the surface cooler fin can be a common stainless steel foil, but also a hydrophilic stainless steel foil or stainless steel fin; the surface cooling plate can be a galvanized sheet or a stainless steel plate.
2: there are two kinds of fins for the stainless steel tube surface cooler, namely, sine wave and circular arc wave plate 16.
The diaphragm of the 9.52 meter tube cooler is two kinds of double windows.
3: the surface cooler has 4 rows, 6 rows, and 8 rows (vertical tubes).
The 4: surface cooler is divided into the left and right type.
Five: the classification of the surface cooler
In general, it can be divided into * * * *
1: serpentine coil type: there are fan coil units, air conditioning units with flat type, mobile medium can be frozen water, hot water, industrial frozen brine and so on.
Six: the application of the surface cooler;
1: fan coil type surface cooling device. 2: combined air conditioning unit, ceiling air conditioning unit, new air conditioning unit, vertical air conditioning air conditioning unit, jet set, combined air conditioner, horizontal air conditioning unit and other matching plate cooler 3: all kinds of oil water cooling surface cooler, air cooling surface cooler, warm air model cooler.
Seven: the installation and use of the surface cooler:
1. the surface cooler should be equipped with a special bracket, and it is not allowed to use the nozzle to support the surface cooler.
2. the water supply for the surface coolers should be well maintained in order to reduce heat loss or avoid frosting.
3. cold, the highest point of the hot water pipe should be set up the exhaust point, the lowest point should be set up drainage pipe. In winter, when the surface coolers are not used, the remaining water should be exhausted so as not to freeze and freeze the stainless steel pipes.
4. the cold and hot water used for the surface cooler is not allowed to have impurities such as sand, rust and fiber.

2: cold air model
Among them are air-cooled modular unit, constant temperature and humidity unit, and cold air fan. There are L, U, V, W and so on.
Most of the mobile media are Freon or 407 environmental friendly refrigerant preparations.
