Technical Field

The utility model relates to a detect technical field, concretely relates to refrigeration dryer heat abstractor.

Background

The freeze dryer is a drying device widely used in the field of detection, and is an air dryer which freezes moisture in compressed air below a dew point by using a physical principle to separate the moisture from the air. Limited by the freezing point of water, its dew point temperature can theoretically approach 0 degrees, and in practical cases, the good freeze-dryer dew point temperature is generally around 5 degrees. Because of the working characteristics of forced cooling of the freezing dryer, the freezing dryer also has larger heat productivity, and on the contrary, the drying effect of the freezing dryer can be directly influenced by the heat dissipation effect. The shell heat dissipation is a main heat dissipation path of the freeze dryer, and the traditional method improves the heat dissipation effect by arranging fins on the shell, but the heat dissipation performance is not ideal.

Detailed Description

With reference to fig. 1-4, a heat dissipation device for a freezing dryer comprises a dryer housing 1, wherein a plurality of vertical heat dissipation pipes 2 are uniformly arranged on the side wall of the housing 1, the heat dissipation pipes 2 are semicircular, and the two sides of the heat dissipation pipes are directly welded to the outer surface of the housing 1, so that the connection stability of the heat dissipation pipes is ensured during welding, and the stable heat transfer is ensured. Of course, in order to further improve the heat dissipation effect of the heat dissipation pipe 2, the heat dissipation pipe 2 and the housing 1 are made of copper alloy, aluminum alloy, or other materials.

The top of the shell 1 is provided with an air collection chamber 3, and the upper ends of the radiating pipes 2 extend into the air collection chamber 3 and are communicated with the air collection chamber 3. The top of the air collection chamber 3 is provided with four air outlets 4, as shown in the figure, the four air outlets 4 are distributed on the top of the air collection chamber 3 in a matrix shape, of course, the number of the air outlets 4 can be more or less, which can be designed according to the total amount of heat dissipation. The exhaust outlet 4 is internally provided with a dustproof filter screen and an exhaust fan which is used for exhausting air from the air collection chamber 3 outwards, the exhaust fan is started to exhaust the air in the air collection chamber 3, and negative pressure can be formed in the air collection chamber 3, so that the air in the radiating pipe 2 rises.

The utility model discloses in the use, the exhaust fan is opened, forms the negative pressure in the wind chamber 3 that converges, and the cold air is followed 4 discharges of air exit after gathering in wind chamber 3 by the lower extreme entering cooling tube 2 of cooling tube 2, collecting. Compare with traditional simple fin mode, the utility model discloses a semi-circular cooling tube 2, the inside and outside homoenergetic of cooling tube 2 can carry out the heat exchange with the air, has increased heat radiating area. Meanwhile, as the stable radiating airflow is arranged in the radiating pipe 2, the overall radiating stability of the equipment can be ensured, and the situation that the internal temperature is too high is prevented.
