The specific embodiment
To shown in Figure 6, casing 1 inside of derect refrigerated refrigerator provided by the invention has refrigerating chamber 2 as Fig. 1.Derect refrigerated refrigerator can only have refrigerating chamber 2 or have refrigerating chamber 2 and refrigerating chamber, and its inside also can be provided with the pickles preserving chamber.Be provided with the evaporimeter 10 that its internal separation can be become certain space in the refrigerating chamber 2.That is, the inside of refrigerating chamber 2 is provided with a plurality of evaporimeters 10.Evaporimeter 10 is made up of heat exchange panel 11 and refrigerant pipe 12.Heat exchange panel 11 is divided into certain space with refrigerating chamber 2.The inside of refrigerating chamber 2 can be provided with multilayer heat exchange panel 11.But when the inner space of refrigerating chamber 2 hour, only heat exchange panel 11 is set in the bottom surface of refrigerating chamber 2.The bottom surface 11a of heat exchange panel 11 has certain tiltangle.The shape of back bending song is arranged on the heat exchange panel 11 since the refrigerant pipe 12.As shown in Figure 1, the bottom surface 11a of heat exchange panel 11 is towards the downward-sloping setting of the posterior direction of refrigerating chamber 2.As shown in Figure 2, refrigerant pipe 12 is crooked back and forth along the fore-and-aft direction of refrigerating chamber 2, and also towards the downward-sloping setting of the posterior direction of refrigerating chamber 2.Heat exchanger effectiveness was the highest when the tiltangle of refrigerant pipe 12 was 45 °.Can reduce the food amount of storage of refrigerating chamber 2 when but the tiltangle of refrigerant pipe 12 is excessive.Therefore should be taken into account that above-mentioned factor designs the angle of inclination of suitable refrigerant pipe 12.In addition, need the surface of heat exchange panel 11 is handled, make it have better hydrophily.Plasma surface treatment is a kind of method of above-mentioned surface-treated, its be will activation the ion or the electronics of hydroaropic substance quicken with accelerator, and irradiation substance to be processed, thus form one deck plated film on the surface of substance to be processed.Through after such surface treatment, condensed water will collect in the bottom surface that refrigerant pipe 12 is housed on the heat exchange panel 11 and produce and condense, condensed water after condensing will promptly be discharged to the rear portion of refrigerating chamber 2 along the bottom surface of heat exchange panel 11, thereby can reduce the frosting speed of condensed water on heat exchange panel 11.Below, the refrigerant pipe structure that is provided with on heat exchange panel 11 is illustrated in greater detail.To shown in Figure 4, be formed with a plurality of installation portion 11b as Fig. 2 on the bottom surface 11a of heat exchange panel 11.Each installation portion 11b has the straight shape groove shape structure that is parallel to each other substantially.Can insert in the installation portion 11b refrigerant pipe 12 is set.Refrigerant pipe 12 and installation portion 11b are in contact with one another, thereby the cold air of refrigerant pipe 12 is passed better to heat exchange panel 11.The left side wall of heat

provided with not shown condensate draining.Also the condensed water of the water pipe of autocondensation in the future 13 is sprayed on compressor or the condenser, so that condensate evaporation.The effect of derect refrigerated refrigerator with said structure is as follows.The refrigerant of compressed machine compression will flow through condenser and expansion gear, and inflow evaporator 10 then.But the refrigerant of inflow evaporator 10 is heat of cooling exchange panel 11 when flowing through refrigerant pipe 12, thereby the food on the panel 11 of heat of cooling exchange simultaneously.Because the refrigerant pipe 12 of heat exchange panel 11 has certain tiltangle, therefore, the refrigerant in the refrigerant pipe 12 has higher heat exchanger effectiveness.That is, as shown in Figure 5, be the two-phase state at the refrigerant of refrigerant pipe 12 internal flows, this refrigerant wake flow and eddy current can occur when flowing through the refrigerant pipe 12 of inclination.And this wake flow and eddy current can improve the heat conduction efficiency on refrigerant pipe 12 boundary layer, thereby can improve the heat exchanger effectiveness of refrigerant pipe 12.When continuing within a certain period of time to carry out above-mentioned cooling effect, the humid air in the refrigerating chamber 2 will be attached on the evaporimeter 10, and generates condensed waters on surface treated evaporimeter 10 surfaces.Condensed water collects in the bottom surface 11a that refrigerant pipe 12 is housed on the evaporimeter 10.The condensed water that condenses at heat exchange panel 11 front ends can flow to its rear portion, and in this process, the water droplet of condensed water becomes greatly gradually, is discharged from then, thereby the humid air of refrigerating chamber 2 inside is condensed quickly.As shown in Figure 6, the condensing drip after condensing will promptly drain into along the inclined plane of heat exchange panel 11 in the condensate pipe 13, then discharge.Promptly form the initial stage of the small globule and promptly it is discharged when freezing as yet, so just can reduce the surperficial frosting speed of heat exchange panel 11 at condensed water.In addition, as long as produce certain frost on the heat exchange panel 11, then the speed of frosting will sharply be accelerated, and the result can generate a large amount of frosts.Therefore, the present invention utilizes the method for discharging condensed water fast effectively to postpone the time that produces a certain amount of frost, thereby can prolong the defrosting cycle of evaporimeter 10.
