Fig. 2 is that low-temperature cabinet vaporizer fixing strip is arranged on the three-dimensional structure diagram on the inner bag;
Fig. 3 is the three-dimensional structure diagram that is provided with the low temperature cabinet of low-temperature cabinet vaporizer fixing strip.
The specific embodiment
The cold bundle steel plate of the material selection of low-temperature cabinet vaporizer fixing strip of the present utility model, aluminium sheet or corrosion resistant plate.Low-temperature cabinet vaporizer fixing strip forms with the thick strip cold-rolled steel sheet bending of 0.5mm, and the cross section is L-shaped.Wherein a side has been arranged a plurality of U-lags that spacing differs, and in being used for evaporimeter is fixed on, has guaranteed that the spacing of evaporator tube is fixed.The U-lag bottom contacts with opposite side, so that evaporimeter is close on the inner bag.For the ease of the smooth installation of evaporimeter, on top, U-lag both sides chamfering is arranged, this chamfering can be selected three kinds of parameters such as 1mm * 45 °, 5mm * 45 °, 10mm * 45 ° for use.This low-temperature cabinet vaporizer fixing strip can be widely used in various refrigeration plants, has improved the heat exchange effect.
Below in conjunction with accompanying drawing the utility model preferred embodiment is described in detail.
Shown in the three-dimensional structure diagram of Fig. 1 low-temperature cabinet vaporizer fixing strip 1, low-temperature cabinet vaporizer fixing strip 1 comprises that first plane 2 and 3, the first planes 2, second plane that are connected are provided with U-lag 4.The bottom of U-lag 4 is connected with second plane 3, and just U-lag 4 extends on second plane 3, and the top, both sides of U-lag 4 is provided with chamfering.Low-temperature cabinet vaporizer fixing strip 1 cross section is L-shaped.
Low-temperature cabinet vaporizer fixing strip 1 is selected cold bundle steel plate for use, comprises two mutually perpendicular planes, has formed U-lag 4 on first plane 2, and the width of this U-lag 4 matches with the diameter of evaporator tube 6 (Fig. 3).For the ease of installing, stamping-out has chamfering on the top, both sides of U-lag 4.Second plane 3 is used for installing, and width can be chosen according to actual needs.
Fig. 2 is that low-temperature cabinet vaporizer fixing strip is arranged on the three-dimensional structure diagram on the inner bag, as shown in Figure 2, in this preferred embodiment, two sides at inner bag 5 outer walls respectively are provided with a low-temperature cabinet vaporizer fixing strip 1 in vertical direction, be provided with two low-temperature cabinet vaporizer fixing strips 1 in the back side of inner bag 5 vertical direction, like this, the outer wall at inner bag 5 is provided with 4 low-temperature cabinet vaporizer fixing strips 1 altogether.Low-temperature cabinet vaporizer fixing strip 1 is welded on the inner bag 5.
Shown in the three-dimensional structure diagram of low temperature cabinet that Fig. 3 is provided with low-temperature cabinet vaporizer fixing strip 1, the low temperature cabinet comprises inner bag 5, the outer wall of inner bag 5 is provided with low-temperature cabinet vaporizer fixing strip 1, low-temperature cabinet vaporizer fixing strip 1 is provided with first plane 2 and second plane 3 that is connected, first plane 2 therein is provided with U-lag 4, the second planes 3 and welds mutually with inner bag 5.With the size bending of copper pipe according to inner casing, the evaporator tube 6 after the bending embeds in the U-lag 4, by low-temperature cabinet vaporizer fixing strip 1 evaporator tube 6 is installed in inner bladder outer wall.
The bottom of U-lag 4 extends on second plane 3, like this, can guarantee that evaporimeter 6 is attached on the outer wall of inner bag 5.Low-temperature cabinet vaporizer fixing strip 1 cross section is L-shaped, and first plane 2 and second plane 3 are orthogonal.Install for convenience, be provided with chamfering on the top, both sides of U-lag 4.Low-temperature cabinet vaporizer fixing strip 1 should be one at least, selects 4 in this preferred embodiment for use.
Owing between U-lag 4 and the evaporator tube 6 very little gap is arranged, evaporator tube can axially and vertically not moved.Because U-lag 4 bottoms abut against the outer wall of inner bag 5, and evaporator tube 6 also can be close on the inner bag outer surface, have solved the problem that evaporator tube and inner bag are easy to generate the gap.Owing to have identical gap between the U-lag 4, make that the spacing between the evaporator tube 6 is identical, it is wayward to solve the evaporator tube spacing, influences the problem of temperature homogeneity.Certainly, the spacing between the U-lag also can be different.
Installation method to low temperature cabinet evaporimeter is described in detail below, and this method comprises the following steps:
The utility model is selected cold bundle steel plate for use in order to save cost on material, at first, cold bundle steel plate is put into plate shearing machine cold bundle steel plate is processed into base-material.If the width of base-material does not need plate shearing machine to handle, this step can be omitted.
Next, automatic punching machine is with the base-material bending.In this step, according to the width of vaporizer fixing strip needs the parameter of automatic punching machine is set, can be satisfied the demand in two planes after the bending.
Next, automatic punching machine is gone out groove on a face of the base-material after the bending.The width of this groove will adapt to the diameter of evaporator tube, and evaporimeter can be embedded in this groove, and guarantees not loosening.For easy for installation, above this groove, go out chamfering simultaneously.In the utility model, because evaporator tube is selected copper pipe for use, so this flowing current separation U-lag.
Next describe the process of assembling, step is as follows:
A, cabinet vaporizer fixing strip are installed on the inner bag;
B, the evaporator tube that bending is good embed in the groove of low-temperature cabinet vaporizer fixing strip;
C, the inner bag that will install evaporator tube and the assembling of low temperature cabinet shell.
For better insulation, evaporator tube is fixed on the inner bag better, charge into blowing agent in the space with the inner bag that assembles and inner casing.
Fixed strip and inner bag are by welding or draw anchor to be connected among the step a.
At last, in evaporator tube 6, inject cold-producing medium, again with evaporator tube 6 with after compressor is connected, just formed a complete low temperature cabinet.
