A microchannel heat exchanger structure with a nozzle and a working method thereof. The microchannel heat exchanger structure with a nozzle, includes a first heat exchange portion, a second heat exchange portion, and at least one nozzle portion between the first heat exchange portion and the second heat exchange portion, the first heat exchange portion having a high-pressure heat exchange channel, a first micro-fin array being provided inside the high-pressure heat exchange channel, and the second heat exchange portion having a low-pressure heat exchange channel, the high-pressure heat exchange channel and the low-pressure heat exchange channel being in communication through at least one nozzle disposed in the nozzle portion. The heat exchanger structure has a good heat exchange effect and can achieve a better heat flux during heat exchange.

An aftercooler device with ribs for aligning cooling tubes in a twelve-pass configuration provides a heat exchanger that transfers optimal amount of heat from combustion air through use of a tortuous, back-and-forth arrangement of twelve rows of tubes carrying a coolant fluid, and creating agitation therein for efficient cooling. The cooling tubes are organized into separate rows through heat exchanger body. A top cover fastens to the top end of heat exchanger body. The top cover includes six top ribs that segregate cooling tubes into six rows at top end of the heat exchanger. Four of the top ribs are linear, and two of the top ribs have angled configurations. A bottom cover fastens to the bottom end of the heat exchanger. The top cover includes five bottom ribs that segregate the cooling tubes into six rows at bottom end of heat exchanger. The bottom ribs have a linear configuration.

The present invention provides underground equipment enabling the internal heat of a buried box to be stably discharged to the outside without an external power source. In one embodiment, underground equipment comprises: a buried box of which the top is open; a cover part inserted into the buried box so as to cover the top; and air-conditioning parts which are disposed at the cover part, and which ventilate or close the inner space of the buried box according to the inflow of external water, wherein the inner space of the buried box is closed by means of the lower surface of the cover part, and a heat exchange part for allowing heat to be exchanged between rainwater and the inner space when the rainwater flows therein is disposed at a position of the cover part that differs from the arrangement position of the air-conditioning parts.

A heat exchanger assembly has a top par and a bottom part joined to the top part. At least one of the top and bottom parts defines a recess. The top and bottom parts define therebetween a passage formed in part by the recess. The passage has a first portion of the passage extending along a first side of the heat exchanger assembly; a second portion of the passage extending along a second side of the heat exchanger assembly; an inlet fluidly communicating with the first portion of the passage near a first end of the passage; and an outlet fluidly communicating with the second portion of the passage near a second end of the passage. Fluid enters the passage via the inlet, then flows in the first portion of the passage, then flows in the second portion of the passage, and then exits the passage via the outlet.
