Abstract

The utility model discloses an air cooler, aiming at providing an air cooler which is simple in manufacturing technology, free from a fan and low in noise. In order to solve the problems, the utility model adopts the technical scheme that the air cooler mainly consists of a metal spiral pipe, joints and a flow distribution pipe, wherein an upper opening and a lower opening of the metal spiral pipe are respectively communicated with the flow distribution pipe by the joints. The air cooler not only has the characteristics of being large in heat exchange area, saving material, and being good in pressure resistance and easy to manufacture; compared with the exiting air coolers such as an engine cooling water tank, an air compressor intercooler, and a condenser in an air conditioner, the air cooler also omits a fan, a fan motor or a fan driving system. After the air cooler is adopted, the manufacturing cost is greatly reduced, and the power is not consumed, so that the fuel is saved when the air cooler is used for an engine, and the electricity is saved when air cooler is used for the air conditioner or an air compressor.

Description

an air cooler

technical field

The utility model relates to a heat exchanger, in particular to an air cooler using air as a cooling medium.

Background technique

Existing air coolers, such as engine cooling water tanks, intercoolers of air compressors, and condensers in air conditioners, use copper or aluminum tubes with additional fins, and are equipped with fans to blow air to form a complete cooling system. This system has three disadvantages: 1. The fins must be in close contact with the tube, so it is difficult to manufacture. 2 The fan needs power, so it consumes electricity or oil. 3 The fan makes noise when it is running.

Utility model content

The technical problem to be solved by the utility model is to provide an air cooler with simple manufacturing process, no fan and low noise.

In order to solve the above problems, the technical solution adopted by the utility model includes an air cooler, which is characterized in that: the air cooler is mainly composed of a metal spiral pipe, a joint, and a distribution pipe, and the upper and lower ports of the metal spiral pipe pass through the joint and the distribution pipe. connected.

The air cooler is characterized in that: the metal spiral tube is formed by one or more metal tubes helically and densely wound.

The air cooler is characterized in that: the number of the metal spiral tube is one or more.

The air cooler is characterized in that: a support frame is arranged between the distribution pipes.

The air cooler is characterized in that: the outer surface of the metal spiral tube is provided with a sheath.

The utility model has the following advantages:

This air cooler not only has a large heat exchange area, saves materials, but also has good pressure resistance and is easy to manufacture. It is different from existing air coolers, such as engine cooling water tanks, air compressor intercoolers, and condensers in air conditioners. In contrast, the fan, fan motor or fan drive system can also be omitted. Not only greatly reduces the cost of the air cooling system, but also no longer consumes power. It can save fuel when used in engines, and save electricity when used in air conditioners or air compressors.

Description of drawings

Below in conjunction with accompanying drawing and specific embodiment, the utility model is described in further detail.

Fig. 1 is the structural representation of the utility model.

Detailed ways

As shown in Figure 1, the air cooler of the present utility model is mainly composed of a metal spiral tube 3, a joint 2, and a distribution pipe 1. The metal spiral tube 3 is composed of one or more metal tubes (the metal tube can be a copper tube , aluminum tube or stainless steel tube, etc.) are densely wound in a spiral. The upper and lower openings of the metal spiral tube 3 communicate with the distribution tube 1 through the joint 2 .

According to needs, the number of said metal spiral tubes 3 can be one or more. A support frame 4 may be provided between the distribution pipes 1 . The outer surface of the metal spiral tube 3 is provided with a sheath 5, and the sheath 5 is generally made of a thin steel plate.

Working principle: The cooling medium flows in from the upper distribution pipe 1, flows into the metal pipe of the corresponding spiral straight tube 3 through the joint 2, gathers at the lower end distribution pipe 1 and flows out, the air is sucked in from the lower port of the straight tube, and discharged from the upper port, using the chimney effect to increase Large air flow and cooling capacity, the support 4 is used to maintain the overall rigidity and height of the air cooler, and the sheath 5 surrounds the spiral straight tube to protect and form the upper and lower air flow channels.

The above descriptions are only preferred embodiments of the present utility model, and are not intended to limit the present utility model. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present utility model are all included in the utility model. within the scope of protection.
