Abstract

The utility model relates to a roll-bond evaporator which is simple in structure, high in reliability, and high in heat exchange efficiency. The roll-bond evaporator comprises a roll-bond evaporator body. A groove is formed in the surface of the roll-bond evaporator body, opening seams are formed in the bottom wall of the groove, the opening seams are parallel to the bottom wall of the groove, the length of the opening seams are h and the opening seams are convenient in airflow, so that the area of the bottom wall of the groove of the surface of the roll-bond evaporator body is not reduced, and the problem that melted frost on the upper surface of the roll-bond evaporator needs to be excluded when a compressor shuts down is solved. When the compressor works again, the upper surface of the roll-bond evaporator body is no longer frozen, and is relatively dry, so that the air can flow to achieve the heat exchange with the upper surface of the roll-bond evaporator directly. The roll-bond evaporator is simple in structure, high in reliability, and high in heat exchange efficiency.

Description

A kind of inflation type evaporator

Technical field

The utility model relates to an electro-technical field, is specially a kind of inflation type evaporator.

Background technology

The inflation type evaporator of using on refrigerator at present, is horizontal positioned mostly, and effectively heat-exchange surface only has lower surface; Upper surface, because area is large, after air is cooling on upper surface, does not flow substantially, and therefore heat exchange efficiency is low.In use, when compressor operating, the surperficial frosting of inflation type evaporator, when compressor shutdown, the frost layer of the upper surface of inflation type evaporator is melted naturally, and its defrosting water is gathered on inflation type evaporator upper surface; When compressor is worked again, the defrosting water meeting glaciation on inflation type evaporator upper surface, air can not directly contact with inflation type evaporator upper surface like this, thereby causes the heat exchange variation of inflation type evaporator and air, affects refrigeration.For addressing this problem raising heat exchange efficiency, prior art personnel have the through hole of up/down perforation on the groove diapire of inflation type evaporator body, when compressor shutdown, the frost layer of the upper surface of inflation type evaporator is melted naturally, its defrosting water can be discharged and be flow to drip tray by through hole, when compressor is worked again, the upper surface of body is no longer icing like this, relatively dry, air can directly and heat exchange be carried out on the surface of inflation type evaporator so that raising heat exchanger effectiveness, but for the groove that solves body has defrosting water problem, must on diapire, have the abundant through hole of up/down perforation, certainly will reduce like this heat exchange area of body recess diapire, affected equally the refrigeration of inflation type evaporator.

Summary of the invention

The purpose of this utility model is to provide a kind of simple in structure, reliability is high, heat exchange efficiency is high inflation type evaporator.

In order to achieve the above object, the utility model solves the problems of the technologies described above adopted technical scheme: a kind of inflation type evaporator, comprise body, the surface of described body is provided with groove, the diapire of described groove is provided with and cracks, and the diapire at the place, both sides of cracking pulls open certain distance h along the vertical direction.

The distance h that the described diapire that cracks place, both sides pulls open is along the vertical direction 1-9mm.

Described body is tabular.

Described body is comprised of flat board or U-shaped plate or L shaped plate or C shape plate.

Described groove is multiple, described in crack for multiple, respectively on the corresponding diapire that is located at multiple described grooves.

Described body is made by aluminum.

Adopt after said structure, owing to being provided with and cracking on the groove diapire at body surface, and the diapire at the place, both sides of cracking pulls open certain distance along the vertical direction.Formation window parallel with diapire in place's is equivalent to crack on the groove diapire of body surface; be convenient to Air Flow; so both do not reduced the area of the groove diapire of body surface; solved again when compressor shutdown; defrosting water queueing problem on inflation type evaporator upper surface, its defrosting water can be discharged and be flow to drip tray by this window.When compressor is worked again, the upper surface of body is no longer icing like this, relatively dry, and air can flow directly and the upper surface of inflation type evaporator carries out heat exchange.The utlity model has advantage simple in structure, that reliability is high, heat exchange efficiency is high.

Accompanying drawing explanation

Fig. 1 is the structural representation of the utility model inflation type evaporator;

Fig. 2 is the front view of Fig. 1;

Fig. 3 is A-A cross section enlarged drawing in Fig. 1;

Fig. 4 is B-B cross section enlarged drawing in Fig. 1.

The specific embodiment

The embodiment providing below in conjunction with accompanying drawing is described in further detail the utility model.

Referring to Fig. 1,2,3,4, shown in, a kind of inflation type evaporator, its innovation is: comprise body 1, the surface of described body 1 is provided with groove 2, the diapire of described groove 2 is provided with the 2-1 that cracks, and the diapire at the place, 2-1 both sides of cracking pulls open certain distance h along the vertical direction.The 2-1 place that is equivalent to crack on groove 2 diapires on body 1 forms a window parallel with groove 2 diapires; so both do not reduced the area of groove 2 diapires on body 1; solved again when compressor shutdown; defrosting water queueing problem on inflation type evaporator upper surface, its defrosting water can be discharged and be flow to drip tray by this window.When compressor is worked again, the upper surface of body 1 is no longer icing like this, relatively dry, and air can flow directly and the upper surface of inflation type evaporator carries out heat exchange.

Referring to Fig. 4, in order to make the defrosting water that is gathered in body upper surface, discharge, be convenient to Air Flow, described in the distance h that the diapire at place, 2-1 both sides pulls open along the vertical direction of cracking be 1-9mm, the distance h that the diapire at the place, 2-1 both sides of cracking in the present embodiment pulls open is along the vertical direction 5 mm.

Referring to Fig. 1, described body 1 is tabular.

Referring to Fig. 1, described body 1 is comprised of flat board or U-shaped plate or L shaped plate or C shape plate, in other words body 1 can have the shapes such as plate shaped, U-shaped, L shaped or C shape, particularly, body 1 can carry out bending to form the shapes such as U-shaped, L shaped or C shape by flat board, so that install, be conducive to make full use of the space in refrigerator in refrigerator.

Referring to Fig. 1,4, in order to increase heat exchange area and to improve heat exchange efficiency, described groove 2 is multiple, described in the 2-1 that cracks be on multiple corresponding diapires that are located at multiple described grooves 2 respectively.

Described body 1 is made by aluminum, both convenient processing, and heat transfer effect is good again.

Referring to Fig. 1,4, in use, by the 2-1 that cracks is set on the diapire of the groove 2 at body 1, and the diapire at the place, 2-1 both sides of cracking pulls open certain distance h to the utility model along the vertical direction.Be equivalent to form a window parallel with groove 2 diapires at the 2-1 place of cracking of groove 2 diapires of body 1, thus make to be gathered in defrosting water on the upper surface of body 1 by crack 2-1 smoothly discharge flow in drip tray.The area that had not so both reduced groove 2 diapires on body 1, has solved again when compressor shutdown the queueing problem of the defrosting water on inflation type evaporator upper surface.When compressor is worked again, the upper surface of body 1 is no longer icing like this, relatively dry, and air can flow directly and the upper surface of inflation type evaporator carries out heat exchange, to improve heat exchanger effectiveness.
