Abstract
The utility model provides a surface air cooler for a low air volume fan coil unit. The surface air cooler comprises a surface air cooler elbow group, surface air cooler sealing plates, surface air cooler fins, an air release valve, a first collecting head and a second collecting head, wherein the surface air cooler elbow group is divided into two rows, and each row consists of a plurality of U-shaped bends and a plurality of surface air cooler elbows; the surface air cooler elbows are communicated through the U-shaped bends; the surface air cooler elbows respectively penetrate through the surface air cooler sealing plates and the surface air cooler fins; the surface air cooler fins are arranged between the surface air cooler sealing plates; two copper tubes are arranged on each of the first and second collecting heads; the two copper tubes on the first collecting head are in sealed connection with the inlet of the surface air cooler elbow group; the two copper tubes on the second collecting head are in sealed connection with the outlet of the surface air cooler elbow group; the air release valve is arranged on the second collecting head. The surface air cooler has the beneficial effects that the surface air cooler can better ensure a smooth water system and guarantee the best heat exchange effect for the low air volume fan coil unit.
Description
Technical field
The utility model belongs to refrigeration air-conditioner end technology field, especially relates to a kind of low air quantity fan coil units surface cooler.
Background technology
Along with social economy constantly develops, people are more and more higher to living space environmental requirement, all kinds of air-conditionings have all entered the place of ordinary people family or various commercial uses, user is more and more higher to the serviceability of machine group end, comprises running refrigerating (heat) ability, unit eer of end etc.If can make the heat transfer effect of surface cooler reach best, just be beneficial to machine group end and reach best duty.Due in heat exchange area and the approximately equalised situation of the temperature difference, total heat exchange amount and the coefficient of heat transfer are directly proportional, the coefficient of heat transfer increases, total heat exchange amount will increase, and then guarantee that heat transfer effect reaches best, so require fan coil units on the low side for air quantity, how to guarantee that heat transfer effect reaches the best part flow arrangement that just needs reasonably to select.
Summary of the invention
Problem to be solved in the utility model is to provide a kind of low air quantity fan coil units surface cooler, is especially applicable to making fan coil units (200-400CFM) heat transfer effect to reach best.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of low air quantity fan coil units surface cooler, comprise surface cooler bend pipe group, surface cooler shrouding, surface cooler fin, air bleeding valve, the first collecting head, the second collecting head, described surface cooler bend pipe component is two rows, every row forms by some U-shaped elbows and some surface cooler bend pipes, described some surface cooler bend pipes are connected by described some U-shaped elbows, described surface cooler bend pipe is respectively through described surface cooler shrouding and described surface cooler fin, described surface cooler fin is arranged between described surface cooler shrouding, described the first collecting head, on the second collecting head, be equipped with two copper pipes, two copper pipes on described the first collecting head are connected with the inlet seal of described surface cooler bend pipe group, two copper pipes on described the second collecting head are connected with the exit seal of described surface cooler bend pipe group, described air bleeding valve is arranged on described the second collecting head.
Advantage and the good effect that the utlity model has are: owing to adopting technique scheme, for low air quantity (200-400CFM) fan coil units, surface cooler adopts two control, because surface cooler entire length is partially short, and total quantity of circulating water is certain, the in the situation that of selected hydraulic pressure, it is bigger than normal that interior two pipes of unit are enter the water velocity of entering than three pipes, can better guarantee that water system is smooth, guarantee that heat transfer effect reaches best.

The specific embodiment
As Fig. 1, Fig. 2, Fig. 3, Fig. 4, shown in Fig. 5, the utility model provides a kind of low air quantity fan coil units surface cooler, this surface cooler fan coil units air quantity is 200CFM-400CFM, comprise surface cooler bend pipe group, surface cooler shrouding 2, surface cooler fin 3, air bleeding valve 5, the first collecting head 7, the second collecting head 6, surface cooler bend pipe component is two rows, every row forms by some U-shaped elbows 4 and some surface cooler bend pipes 1, surface cooler bend pipe 1 is connected by U-shaped elbow 4, surface cooler bend pipe 1 is respectively through surface cooler shrouding 2 and surface cooler fin 3, surface cooler fin 3 is arranged between two blocks of surface cooler shroudings 2, U-shaped elbow 4 is tightly connected with surface cooler bend pipe 1, on the first collecting head 7, the second collecting head 6, be equipped with two copper pipes, two copper pipes on the first collecting head 7 are connected with the inlet seal of surface cooler bend pipe group, two copper pipes on the second collecting head 6 are connected with the exit seal of surface cooler bend pipe group, and air bleeding valve 5 is arranged on the second collecting head 6.
The course of work of this example: chilled water is entered by the first collecting head 7 and divides two-way to enter surface cooler bend pipe 1, and along with surface cooler bend pipe 1 is through surface cooler shrouding 2, afterwards again through surface cooler fin 3, the mobile chilled water in surface cooler bend pipe 1 the inside is cooling the air of the surface cooler fin 3 of flowing through, and blower fan is delivered to field of employment cooling by the cold air after cooling; Final chilled water flows to the second collecting head 6 with absorbed heat, is finally brought back refrigeration unit, emits the air that is sent back to again surface cooler heat absorption, cool stream warp after heat, cooling, constantly circulation.In this course, due in heat exchange area and the approximately equalised situation of the temperature difference, total heat exchange amount and the coefficient of heat transfer are directly proportional, because of the first collecting head 7, the second collecting head 6, be provided with two copper pipes again, in the situation that total quantity of circulating water is certain, hydraulic pressure is certain, in unit are, in copper pipe, water velocity strengthens, the coefficient of heat transfer is increased, total heat exchange amount increases, and then guarantees that heat transfer effect reaches best, and Energy Efficiency Ratio strengthens.
Above an embodiment of the present utility model is had been described in detail, but described content is only preferred embodiment of the present utility model, can not be considered to for limiting practical range of the present utility model.All equalization variations of doing according to the utility model application range and improvement etc., within all should still belonging to patent covering scope of the present utility model.
