Problems solved by technology

The composite plate evaporator has the advantages of fast cooling speed, low cost and easy processing, and uses internal circulation fan and air duct to strengthen the air flow in the box to achieve the purpose of rapid cooling, but due to the limitation of the structure of the composite plate evaporator, the wind direction It can only circulate from top to bottom from the front or back of the composite plate evaporator. The temperature at the lower air outlet is low, and the temperature of the items stored in the top and middle is high. The temperature difference between the top and bottom of the box is too large, and the maximum temperature difference is about 10 degrees. An air channel plate, the air channel plate is located on one side of the evaporator, an air channel is formed between the air channel plate and the evaporator, and several air channel holes are arranged on the air channel plate from top to bottom, and the fan passes through the air channel and passes through the air channel The ventilation holes on the board send cold air into the box to achieve uniform temperature in the box, thereby ensuring the quality of the stored items, but the cost of adding an air duct plate is higher

Embodiment 1

[0029] refer to figure 1 As shown, a composite plate evaporator 10 includes two aluminum plates 11 that are pressed together. The periphery of the two aluminum plates 11 is all pressed and has fixing holes 12 to facilitate fixing the evaporator on the inner tank. The center of the two aluminum plates 11 It includes a pressing part 111 and a channel part 112, that is, the central part of each aluminum plate 11 includes a pressing part 111 and a channel part 112, and several ventilation holes 113 are opened on the pressing part 111 in the center of the two aluminum plates 11.

[0030] Ventilation holes 113 are strip-shaped, and the ventilation holes 113 are distributed in the whole body of the evaporator 10 from top to bottom, including 5 rows, and the number of ventilation holes 113 on each row is 2, 3, and 2 from top to bottom. , 3, 4.

[0031] Such as figure 1 As shown, the channel part 112 between the two aluminum plates 11 is a strip-shaped cavity formed by continuous ben...

Embodiment 2

[0034] Such as figure 2 As shown, a refrigerator 20 includes a box body 21 and a glass door 22. The box body 21 includes a box shell 211 and an inner container 212. The inner container 212 is provided with a composite plate evaporator 10, a fan 23, and a shelf 24. The composite plate evaporator 10 is fixedly connected to the inner container rear wall 213. The structure of the composite plate evaporator 10 is the same as that described in Embodiment 1, and will not be repeated here. Wherein, the composite plate evaporator 10 and the inner container rear wall 213 The air duct 25 is formed in between, that is, the inner tank rear wall 213 and the composite plate evaporator 10 enclose the air duct 25, the composite plate evaporator 10 serves as the function of the air channel plate, and the composite plate evaporator 10 serves as a heat exchanger while simultaneously The function of the air channel plate is dual-purpose, which saves costs. The fan 23 sends cold air to the box thr...

Abstract

The invention provides a composite board evaporator and refrigeration equipment. The composite board evaporator comprises two aluminum boards combined together in a pressing mode, wherein the peripheries of the two aluminum boards are combined in a pressing mode and provided with fixing holes, the centers of the two aluminum boards comprise pressing combination parts and passage parts, and the pressing combination parts at the centers of the two aluminum boards are provided with a plurality of vents. The invention further provides the refrigeration equipment with the composite board evaporator. An air passage is formed between the composite board evaporator and the rear wall of an inner container, the composite board evaporator serves as a heat exchanger and has the function of an air passage board, and a fan supplies cold air into a box through the air passage and the vents in the evaporator so that the temperature inside the box can be uniform. As the air passage board is omitted, the cost is reduced, and the heat exchange efficiency is high.

Description

technical field [0001] The invention belongs to the technical field of refrigeration, and in particular relates to a composite plate evaporator and refrigeration equipment using the composite plate evaporator. Background technique [0002] At present, composite plate (inflation) evaporators are mostly used in refrigerators, showcases, refrigerators and other series of refrigeration equipment. The composite plate (inflation) evaporator is made of two pieces of aluminum plates pressed together, and the unpressed part is the refrigerant channel. The parts other than the channel are all pressed together. The size or width of the refrigerant channel is adjusted according to the pressing part of the mold. There are fixing holes around the two aluminum plates for fixing the evaporator on the rear wall of the inner tank. The composite plate evaporator has the advantages of fast cooling speed, low cost and easy processing, and uses internal circulation fan and air duct to strengthen ...
