Embodiment 1

[0017] A high-efficiency condenser for a plate-and-tube refrigerator, comprising: an aluminum heat dissipation fixing plate 1, a microchannel pipe and a superheated steam inlet pipe 2; the microchannel pipe is fixed on the heat dissipation fixing plate 1 by riveting, and A distance of 1.5 cm is left between the lower surface of the channel tube and the upper surface of the heat dissipation fixed plate to ensure air circulation.

[0018] The micro-channel tube comprises an upper integrated tube 3, a lower integrated tube 4 and a vertical tube bundle 5, the superheated steam tube 2 communicates with the upper integrated tube, and the lower integrated tube 4 is provided with a condensate outlet 6; The vertical pipe bundle 5 is composed of a straight pipe section and an S-shaped pipe section; wherein, the straight pipe section has two ends, and the S-shaped pipe section is embedded between the two straight pipe sections.

[0019] In the high-efficiency condenser of the above-menti...

Embodiment 2

[0021] A high-efficiency condenser for a plate-and-tube refrigerator, comprising: a heat dissipation fixing plate 1, a microchannel pipe and a superheated steam inlet pipe 2; the microchannel pipe is fixed on the heat dissipation fixing plate 1 in the form of an adhesive, and A distance of 2 cm is left between the lower surface of the tube and the upper surface of the cooling plate to ensure air circulation.

[0022] The micro-channel tube comprises an upper integrated tube 3, a lower integrated tube 4 and a vertical tube bundle 5, the superheated steam tube 2 communicates with the upper integrated tube, and the lower integrated tube 4 is provided with a condensate outlet 6; The vertical pipe bundle 5 is composed of a straight pipe section and an S-shaped pipe section; wherein, each of the straight pipe section and the S-line pipe section has one section, and the straight pipe section communicates with the upper integrated pipe 3, and the S-shaped pipe section communicates with...

Embodiment 3

[0025] The difference from Example 2 is that the straight pipe section communicates with the lower manifold 4, and the S-shaped pipe section communicates with the upper manifold 3; the distance between the pipes is 15 cm.

[0026] Compared with existing condensers, the condenser in the above embodiment saves materials by more than 30%, and improves heat exchange efficiency by more than 10%.

Abstract

The invention discloses a plate and tube type refrigerator efficient condenser. The plate and tube type refrigerator efficient condenser comprises a heat dissipation fixing plate, a micro-channel tube and a superheated steam inlet tube, wherein the micro-channel tube is fixed to the heat dissipation fixing plate and comprises an upper integrated tube, a lower integrated tube and vertical tube bundles, the superheated steam tube is communicated with the upper integrated tube, and a condensate outlet is formed in the lower integrated tube; the vertical tube bundles are composed of straight tube sections and S-shaped tube sections. Through reasonable tube bundle design and spatial structure design, pressure drop difference inside a condenser pipe is effectively reduced, meanwhile, convective diffusion efficiency is improved, materials are saved, the cost is lowered, and heat dissipation and cooling efficiency is high.

Description

technical field [0001] The invention relates to the field of condensers, in particular to a high-efficiency condenser of a plate-tube refrigerator. Background technique [0002] The structure of the existing refrigerator refrigerator has the following characteristics: 1. The condensing pipe is embedded in the fixed plate; 2. Almost all the condensing pipes adopt a serpentine pipe structure. The refrigerator with the above structure has the following disadvantages: 1. The length of the single condensing tube is too long, and the pressure drop inside the tube is too large; 2. There is no space inside the fixed plate, so the consumption of tubes is large and the cost is high. Contents of the invention [0003] The technical problem mainly solved by the present invention is to provide a high-efficiency condenser of a plate-tube refrigerator, which can solve the above-mentioned problems existing in the condenser pipe of the existing refrigerator. [0004] In order to solve the...
