Technical field

This utility model relates to refrigerating evaporator technology, particularly relates to a kind of racetrack wire-tube evaporator.

Background technology

Refrigerator freezing vaporizer is that refrigerant liquid after reducing pressure by regulating flow enters vaporizer, flashes to gas from surrounding medium heat absorption, makes ambient air temperature reduce, it is achieved freezes, and is one of important building block of refrigeration system. Existing vaporizer body structure is varied according to different purposes, if the patent announcement number of opening is CN203274365U, a kind of wire-tube evaporator, it is by the upper strata vaporization chamber of wire-and-tube evaporator, middle vaporization chamber and the 3rd vaporization chamber are constituted, the upper strata of wire-and-tube evaporator is welded with finned evaporator, and evaporator fin is to be exported by vaporization chamber, and vaporization chamber entrance and aluminum pipe are consisted of outside framework welding. And for example patent publication No. is a kind of double-deck wire-tube evaporator that CN202993671U proposes, and evaporation tube unit includes coil portions, is fixedly connected on the tinsel of coil portions two sides; Being provided with another evaporation tube unit above or below evaporation tube unit, this evaporation tube unit includes coil portions, is fixedly connected on the tinsel of coil portions two sides. For another example patent announcement number is the CN202328926U a kind of wire-tube evaporator designed, S-shaped bending, is provided with iron wire, and iron wire is S-shaped alternating bending shape also, and the side of wire-tube evaporator is located at by iron wire, and iron wire all welds with the junction point of wire-tube evaporator. In these structures, the contact between steel wire and evaporation tube is all coordinate in dots, and its radiating rate is unsatisfactory.

Summary of the invention

The purpose of this utility model is to solve after existing circular evaporation tube bends molding, welding wire on snakelike, there is weld defect in welding position great Yi, and evaporation tube and single steel wire are point cantact, the problem that its way of contact does not reach better heat dissipation effect, there is provided a kind of reasonable in design, steel wire and evaporation tube with the racetrack wire-tube evaporator of linear contact lay.

Above-mentioned technical problem of the present utility model is addressed mainly by following technical proposals: a kind of racetrack wire-tube evaporator, including an evaporation tube, the steel wire being positioned at evaporation tube surface, it is characterized in that a described evaporation tube forms some layers of evaporation tube unit in the back and forth mode of turning around, each evaporation tube unit has some in the being generally aligned in the same plane bodys being parallel to each other, body two ends are arc connector, described steel wire arranges that on two faces of body being parallel to each other in the same plane, the cross section of body is long waist shaped. The cross section of evaporation tube has mainly been carried out racetrack flattening and has processed by the technical program, under keeping the original conveying capacity state of evaporation tube, evaporation tube and steel wire is made to be improved to linear contact lay by point cantact, accelerate to send out evaporation tube and extraneous rate of heat exchange, thus improving refrigeration system heat exchanger effectiveness. The evaporation tube entirety pipe fitting of this structure also carries out positive circular sliding slopes break-in with racetrack, it is thus achieved that structural strength preferably.

As preferably, the cross section of described evaporation tube body is long waist shaped, and two waists of long waist shaped are parallel lines, and steel wire and described parallel lines are close to. Evaporation tube cross section reasonably deforms, and not only ensures body intensity, and provides the maximum contact area between body and steel wire.

As preferably, its two waists length of the cross section of described evaporation tube body is equal, and circular sliding slopes, the length of every circular arc and every waist appearance etc. are passed through in the two ends of two waists. The positive circle cross-section of isosceles easily makes, trombone slide stable molding.

As preferably, the cross section of described evaporation tube body is square or rectangular pipe. Principle according to this programme, the further design to evaporation tube body shape of cross section, its principle is to ensure that under normal pipeline traffic capacity premise, and each thermal component direction of travel is constant, constancy of volume time, make steel wire coordinate with the face way of contact with evaporation tube.

As preferably, described steel wire vertical with evaporation tube and along body maximum two parallel planes arrange.

The beneficial effects of the utility model are: considerably increase the contact area between evaporation tube and steel wire, accelerate evaporation tube inner refrigerant and external heat transmission, namely condenser and extraneous radiating rate are accelerated, thus improving refrigeration system heat exchanger effectiveness, reduce compressor operating time, reduce energy consumption.

Detailed description of the invention

By the examples below, and in conjunction with accompanying drawing, the technical solution of the utility model is described in further detail.

Referring to Fig. 1, Fig. 2, the present embodiment one racetrack wire-tube evaporator, four layers of evaporation tube unit are constituted in the back and forth mode of turning around by an evaporation tube 1, each evaporation tube unit has 10 bodys being parallel to each other in being generally aligned in the same plane, namely have 5 to turn around back and forth, body two ends are arc connector, and arc connector is a part for positive round, the bend shape in runway. Arrange steel wire 2 on evaporation tube 1 surface, steel wire 2 is arranged on two faces of the evaporation tube body being parallel to each other in the same plane.

The cross section of evaporation tube 1 body is long waist shaped, and specifically, two waists of the cross section long waist shaped of evaporation tube 1 body are parallel lines, and these two parallel lines are exactly the position of steel wire 2 and its snug fit, as shown in Figure 3. The cross section two waist length of evaporation tube 1 body is equal, and the two ends of two waists are connected by full circle camber line, and the length of every circular arc and every waist appearance etc., namely two waist length and two turning arc length are all equal. Steel wire 2 and evaporation tube 1 parallel tubes are arranged vertically, and maximum two parallel planes laminating spot welding along body.

The cross section of evaporation tube 1 body can also is that other regular polygon body such as square, rectangle, equally, steel wire 2 vertical with evaporation tube 1 parallel tubes and along body maximum two parallel planes arrange.

Above-described embodiment is to explanation of the present utility model, is not to restriction of the present utility model, any structure after simple transformation of the present utility model is belonged to protection domain of the present utility model.
