Abstract
The utility model discloses a heat radiation device of an electronic medical refrigerating box, which comprises the following components: a semiconductor refrigerating chip, and a heat radiation sheet which is adhibited on the heat end of the semiconductor refrigerating chip. The heat radiation device of the electronic medical refrigerating box is characterized in that: heat radiation tubes are inserted on the heat radiation sheet; each heat radiation tube is internally provided with liquid coolant; at least one heat radiation tube is provided; when the heat radiated from the heat end of the semiconductor refrigerating chip is radiated out through the heat radiation sheet, the liquid coolant in the heat radiation tube turns to gas state in contact with the heat; the gas coolant rises in the tube and turns to liquid coolant in contact with low-temperature air in rising process; and the liquid coolant returns into the heat radiation sheet along the tube wall. The process is performed circularly. The heat radiation device of the electronic medical refrigerating box has the following advantages: remarkable heat radiation effect and no noise.
Description
Technical field
The utility model relates to a kind of heat abstractor, is the heat abstractor of the medical refrigerated case of a kind of electronics specifically.
Background technology
Electronic cooling (or being semiconductor refrigerating) technology widespread usage on the utensil of all kinds of little colds, usually semiconductor refrigeration chip has cold junction and hot junction, in order to strengthen radiating effect, except fin is arranged, also increase fan and carry out forced-air circulation, heat is spread out of as far as possible, hot-side temperature is reduced, also reduced cold junction temperature simultaneously, but the forced convertion of fan no doubt has positive effect to cooling, but its noise is big, especially inconvenience is being used in the place that the noise requirement is arranged.
Summary of the invention
The purpose of this utility model provides the heat abstractor of a kind of good heat dissipation effect and the medical refrigerated case of noiseless electronics.
The purpose of this utility model is achieved through the following technical solutions:
The heat abstractor of the medical refrigerated case of a kind of electronics comprises semiconductor refrigeration chip and the fin that sticks on the semiconductor refrigeration chip hot junction, it is characterized in that: be inserted with radiating tube on the described fin.
Be provided with liquid refrigerants in the described radiating tube.
Described radiating tube is at least one.
The heat abstractor of the medical refrigerated case of a kind of electronics of the utility model adopts the heat pipe switching technology to replace the fan heat radiation, liquid refrigerants becomes gaseous state in the radiating tube after accepting heat, gaseous coolant rises in pipe, in uphill process, meet low temperature liquefy refrigerant again, liquid refrigerants is got back in the fin along tube wall again, so circulation, radiating effect is obvious.
Description of drawings
Fig. 1 is the structural representation of the heat abstractor of the medical refrigerated case of a kind of electronics of the utility model;
The specific embodiment
Below in conjunction with accompanying drawing the utility model light fixture is described in further detail.
As shown in the figure, the heat abstractor semiconductor refrigeration chip 1 of the medical refrigerated case of a kind of electronics of the utility model and the fin 2 that sticks on semiconductor refrigeration chip 1 hot junction, be inserted with radiating tube 3 on the fin 2, be provided with liquid refrigerants in the radiating tube 3, when giving out heat, semiconductor refrigeration chip 1 hot junction distributes by fin, liquid refrigerants in the radiating tube runs into heat can become gaseous state, gaseous coolant rises in pipe, in uphill process, meet low temperature liquefy refrigerant again, liquid refrigerants is got back in the fin along tube wall again, so circulation, radiating effect is obvious, and noiselessness.
Claims (3)
