Description

Heat pipe heat radiation type miniature electronic refrigerator

Technical field

The utility model relates to a kind of refrigerator, specifically is a kind of micro refrigerator that adopts heat pipe to add the semiconductor refrigerating of fan heat dissipation type.

Background technology

Semiconductor refrigerating technology possesses that volume is small and exquisite, pollution-free, noiselessness, simple in structure, can multiple occasion use etc. advantage.But present electronic refrigerator product adopts the aluminium fin to add this traditional heat dissipation technology of fan more, causes can only obtaining in the refrigerator refrigerated storage temperature (under 25 ℃ of environment temperatures, oven temperature, is generally 2～8 ℃) because of radiating efficiency is low, can't produce ice cube and frozen food.Simultaneously, running up of cooling fan improved the noise and the power consumption of refrigerator, influenced the promotion and application of electronic refrigerator.

Chinese patent literature CN87207010U discloses a kind of " thermoacoustic refrigerator tube radiator ", it has a heat-pipe radiator, heat pipe evaporator section accompanies the heat conduction fixture block of being made up of (A), (B) two heat conduction fixture blocks outward, and there is suitable the ears of an ox or cow on the fixture block both sides, fix with screw.It greatly facilitates the maintenance and the transposing of heat pipe condenser.But the evaporator section of heat-pipe radiator is a single tube, and does not have radiator fan, and its heat exchanger effectiveness is not high enough.

Summary of the invention

The utility model technical issues that need to address are, overcome disadvantages of background technology, provide that a kind of evaporator section is arranged is multitube, and the higher miniature electronic refrigerator of heat exchanger effectiveness of radiator fan is arranged.

Heat pipe heat radiation type miniature electronic refrigerator of the present utility model, the casing that comprises a band door, casing heat in the exterior pipework condensation device, condenser accompanies the heat-conducting metal pipe clamp, face of semiconductor refrigerating unit and pipe clamp are fitted, cooler is fitted in another side and the casing, it is characterized in that the communicating pipe of described condenser becomes

Shape, or

Shape, two fixture blocks of heat-conducting metal pipe clamp have the tube seat that matches.Becoming above-mentioned two shapes communicating pipe, make the pipe of heat exchange increase, improved heat exchanger effectiveness, is an innovative point of the present utility model.

As preferably, condenser has the fan that matches outward, also helps improving heat exchanger effectiveness.

The combination of semiconductor refrigerating unit can have pattern.One " heat series connection, independently-powered " pattern: two single-stage semiconductor chilling plates are arranged, press metal derby, first cooling piece, transition plate, second cooling piece, the cooler order is composed in series, and is independently-powered.This pattern toggle speed is slower, but cryogenic temperature is low, can reach-15 ℃.

Its two " heat is in parallel, electricity is connected ": two twin-stage semiconductor chilling plates are arranged, press metal derby, first cooling piece-second cooling piece series-fed, first cooler-second cooler composes in parallel.This pattern toggle speed is very fast, but cryogenic temperature is higher, can reach-5 ℃.

As preferably, connector is located on the two pipe clamp blocks, can save the ears of an ox or cow of protrusion, makes pipe clamp processing simple.

The utlity model has rational in infrastructurely, the refrigerating efficiency height can obtain ice cube, is particularly suitable for the travelling micro refrigerator.
