Embodiment 1

[0048] figure 2 Shown is a schematic structural diagram of the refrigeration equipment provided by this embodiment.

[0049] The refrigeration equipment includes:

[0050] Liner 1;

[0051] The evaporator 2 connected to the inner tank 1;

[0052] The heating device 3 has a distance between the heating device 3 and the evaporator 2. The heating device 3 includes a heat conducting plate 30 fixed to the inner container 1 and a heat source connected to the heat conducting plate 30;

[0053] Wherein, the heat conducting plate 30 has at least one notch on the side 301 on the side close to the evaporator 2.

[0054] Specifically, refer to figure 2 As shown, the evaporator 2 is one of the core components of the refrigeration equipment, including a heat exchange plate 20, and a pipe piece fixed on one side of the heat exchange plate 20, such as an aluminum pipe 21. The liquid refrigerant flows in the aluminum pipe 21, and the gas The temperature of the inner liner 1 on the other side of the he...

Embodiment 2

[0068] The refrigeration equipment provided in the second embodiment is roughly the same as the refrigeration equipment in the first embodiment, the difference lies in: Figure 4 versus Figure 5 As shown, the notches of the plurality of arc-shaped structures 301a are not directly connected, but adjacent notches are connected by a straight connecting portion 301b.

[0069] The above-mentioned linear connecting portion 301b increases the distance between the connection point (virtual) of the two adjacent arc-shaped structures 301a and the bottom of the arc-shaped structure 301a, disguisedly increases the bandwidth L of the thermal temperature gradient distribution range, thereby further reducing the inner tank 1 Cracked.

[0070] In other embodiments, the side edge 301 may be directly connected with the notch in the arc-shaped structure 301a in a part of the area, or may be connected with the straight connecting portion 301b in the notch of the arc-shaped structure 301a in the part o...

Embodiment 3

[0072] The refrigeration equipment provided in the third embodiment is roughly the same as the refrigeration equipment in the first embodiment, the difference lies in: Image 6 versus Figure 7 As shown, the notch on the side 301 of the heat conducting plate 30 on the side close to the evaporator 2 is a V-shaped structure 301c. The V-shaped structure 301c can be realized by cutting off some triangles on the side 301. The above structure takes advantage of the stability of the triangle, making it difficult for the inner container 1 to crack in the direction AB along the side 301 of the heat conducting plate 30. .

[0073] In this embodiment, two adjacent V-shaped structures 301c are directly connected, that is, a zigzag shape is formed. The thermal temperature gradient formed by the zigzag side edge 301 ranges from the tip of a V-shaped structure 301c to the V-shaped structure 301c. A band with a width of L between the connection point with the adjacent V-shaped structure 301c. I...

Abstract

Refrigerating equipment comprises a liner (1), an evaporator (2) connected to the liner (1) and a heating device (3), wherein an interval exists between the heating device (3) and the evaporator (2), the heating device (3) comprises a heat conduction plate (30) and a heat source connected to the heat conduction plate (30), and the lateral side (301) on one side, close to the evaporator (2), of the heat conduction plate (30) is provided with at least one notch. By the notches, sudden change of the cold source of the evaporator (2) and the heat source of the heating device (3) at one linear edge, cold and heat distribution is allowed to have certain gradient range, and the liner (1) cracking problem is relieved.

Description

Technical field [0001] The present invention relates to the technical field of refrigeration, in particular to a refrigeration equipment. Background technique [0002] In refrigeration equipment, an evaporator fixed on the outer wall of the inner tank is generally used to provide a cold source to the inner tank. However, the temperature distribution in the inner tank using only the above-mentioned cold source is generally uneven, especially when the inner tank is large This problem is more prominent. In view of this problem, heating devices are generally installed at other positions on the inner container to compensate for the temperature distribution in the inner container. The heating device generally includes a heat source, such as a heating wire, which is usually fixed on the inner tank through a heat conducting plate. [0003] However, after a period of use, the above refrigeration equipment is prone to cracking of the inner tank, which affects the sealed storage environment...
