[0019] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0020] like Figure 1-2 As shown, a heat pipe air cooler comprises:

[0021] Rack 1;

[0022] The invention is characterized in that: a tube bundle 2 is fixedly installed on the top of the frame 1, a wind tube 3 is connected to the bottom of the tube bundle 2, a fan 4 is fixedly installed on the bottom of the wind tube 3, a motor 5 connected to the fan 4 is provided at the bottom, a shutter 6 is fixedly installed on the top of the tube bundle 2, a tube box 7 is provided inside the tube bundle 2, an outlet flange 8 and an inlet flange 9 are respectively provided on the upper and lower end surfaces of the front end of the tube box 7, and a plurality of heat pipe fin tubes 10 located on both sides of the tube box 7 are provided inside the tube bundle 2.

[0023] In the above structure, support plates 11 for fixing the heat pipe finned tubes 10 are provided on both the left and right sides of the tube bundle 2 .

[0024] In the above structure, side plates 12 are provided on both the front and rear sides of the tube bundle 2 .

[0025] When the heat pipe air cooler of the utility model is working, the medium flows in from the inlet flange of the tube box and flows out from the outlet flange, and the medium circulates in the tube box. A fully enclosed channel is provided inside the tube box for installing the heat pipe fin tubes. The heat pipe fin tubes are installed in the channels on both sides of the tube box. The good thermal conductivity of the heat pipe fin tubes enables the tube bundle to exchange heat over a long distance. The heat pipe fin tubes transfer heat by evaporating and condensing the working fluid in the fully enclosed vacuum tube shell, and have extremely high thermal conductivity; the heat pipe fin tubes do not contact the medium circulating in the tube box, and the heat exchange area can be changed by reducing or increasing the number of heat pipe fin tubes, and the medium temperature can be flexibly adjusted to reduce the leakage of the medium during the heat exchange process. The ends of the heat pipe fin tubes are fixed by a support plate to support the heat pipe fin tubes. A fan and a wind tube are arranged below the tube bundle to drive the air to flow through the tube bundle for heat transfer. A shutter is arranged above the tube bundle, which can control and adjust the air flow direction and protect the heat pipe fin tubes. The heat pipe fin tubes of the heat pipe air cooler are easy to install and disassemble. In winter working conditions, the medium that is easy to condense can reduce the heat exchange by reducing the number of heat pipe fin tubes to achieve the purpose of preventing condensation, while saving the cost of heating the heat pipe fin tubes. Similarly, if the heat exchange is not enough in summer, the heat exchange can also be increased by increasing the number of heat pipe fin tubes. Flexible changes in the heat exchange area can better adapt to various working conditions.

[0026] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
