Abstract
The utility model relates to an evaporator and an evaporating pipe thereof for a water tank cooling device, aiming to enhance the heat exchange performance and the heat exchange speed of the evaporator. The utility model comprises an evaporating pipe and an evaporating panel connected with the outer wall of the evaporating pipe. The inner wall of the evaporating pipe is provided with at least one tank; the tank can be helical or axial. The connection of the pipe and the panel can be in the bonded structure. The evaporator can be the random geometry. The tank enlarges the heat exchange areas of the inner wall of the evaporating pipe and the refrigerant; the bonded structure enlarges the actual heat transfer area between the pipe and the panel. The utility model can enhance 15% of the heat exchanger efficiency.
Description
The utility model relates to refrigeration plant, particularly evaporimeter and the evaporation tube thereof in the direct cooling refrigerator cooling system.
Class in original refrigerator cooling system normally is made of cold-producing medium circulating pump, condenser, the evaporimeter of pipeline connection, the cold-producing medium that charges into pipeline.A kind of band-tube type structure in the evaporimeter constitutes by evaporation tube with evaporation plate that the evaporation tube outer wall links, and evaporation tube is made repeatedly bent back-shaped with metal pipe material, and evaporation plate is made with metallic plate.Evaporimeter integral body is made the shape that matches with refrigerator, is evaporated the cold-producing medium that flows in the pipe behind the heat transferred evaporation plate of the cooled thing around the evaporimeter and the evaporation tube and absorbs and take away.Because the inwall of evaporation tube is smooth shape, and the heat exchange between cold-producing medium and evaporation tube is limited to, applying adhesive tape is adopted in the evaporation tube that in addition has and the binding of evaporation plate, makes contact between the two not tight, influences the heat transmission of evaporation plate to evaporation tube.Thereby make the cold and hot exchange efficiency of evaporimeter undesirable.
Given this, the purpose of this utility model provides a kind of evaporator of refrigerator that improves heat exchange property and heat transfer rate.
The purpose of this utility model is to realize by increasing the evaporation tube inner wall surface area.
Evaporator of refrigerator of the present utility model comprises the tubular evaporation tube of metal and the evaporation plate of the metal plate shape that links with the evaporation tube outer wall, and above-mentioned evaporation tube inwall has at least one tank circuit.Since the setting of the interior tank circuit, the corresponding surface area that increases the evaporation tube inwall.
The above-mentioned tank circuit can be made the spirality angled with the tubular axis line, also can make along tubular axis to axial shape.The shape of cross section of the tank circuit can be trapezoidal or rectangle or other shapes.
Preferably adopt adhesive structure between above-mentioned evaporation tube and the evaporation plate.
Evaporimeter of the present utility model can be made into a kind of arbitrarily geometry that can match with the refrigerator shape.
The utility model is compared with original tube-in-sheet evaporator has following tangible advantage and remarkable result.
One, the evaporation tube inwall is made the tank circuit, has increased the contact area of cold-producing medium and evaporation tube inwall, thereby has increased heat exchange area.Moreover, because of the tank circuit can form capillary effect, make the also corresponding increase of wetted area of its inner surface, also improved heat exchange area.The increase of heat exchange area can improve heat exchange property and heat transfer rate.
Two, the evaporation tube inwall tank circuit is made the spirality angled with the tubular axis line, the turbulence effect of tube refrigerant fluid is increased, and the temperature of cold-producing medium is more even, can fully manage inside and outside heat exchange, thereby reduce the energy consumption of refrigerator, improve the Energy Efficiency Ratio of refrigerator.
Three, adopt adhesive structure between evaporation tube and the evaporation plate, can make the two tight contact, the corresponding real contact area that has increased between the plate pipe has improved heat-transfer effect.
Below, with embodiment and comparative examples accompanying drawing the utility model is elaborated again.
Brief description of drawings.
Fig. 1 is the structural representation of a kind of evaporator of refrigerator of the present utility model
Fig. 2 is the part section enlarged diagram of cross section of the evaporation tube 1 of Fig. 1
Fig. 3 is the local enlarged diagram that the evaporation tube of Fig. 1 is analysed and observe along axis.
A kind of evaporator of refrigerator of the present utility model as Figure 1-3, is made of evaporation tube 1 and evaporation plate 2.
Above-mentioned evaporation tube 1 is made with ten several meters long metal tubes, can select aluminum pipe for use, and processing tens with usual method on the wall within it has the spirality tank circuit 3 appropriate depth and become suitable helical angle with the tubular axis line, and helical angle may be selected to be about 20 °.The tank circuit also can be processed into along tubular axis to axial shape.The shape of cross section of the tank circuit can be trapezoidal or rectangle, perhaps triangle or other shapes.Then, more above-mentioned metal tube is made bent back-shaped or other flat shapes on plane through bending several times.
Above-mentioned evaporation plate 2 is made with sheet metal, can select flat aluminium sheet for use, is cut into required form, and the side outer wall with above-mentioned evaporation tube pastes mutually with a side surface of evaporation plate again, and with common binding agent with the two close adhesion.And then crooked make the geometry that matches with the refrigerator container cavity, as JiongZi Xing or other shapes.
This evaporator of refrigerator can improve heat exchange efficiency 15%.
